How can we tackle to explain the governance mechanism considered to be‘ intermediate?’  If we are to discuss such socioeconomic orders, this paper assumes that we should not be able to link micro-level explanations and macro-level ones concerning the third mode of governance mechanisms all at once. We need to stick to the meso-level at fi rst. The theoretical elaboration since Ouchi’s(1980) discussion of clan-type governance and cumulative empirical research on industrial agglomerations have allowed us to construct a more sophisticated theory called community capital.  In effective communities, members are ‘embedded as insiders’ who serve the purpose of the community, share experiences of failures and successes, and find and deepen their common identity. This limited membership is bound by‘ mutual trust to rely on each other’ for‘ distribution of short-term risks.’ In contrast to social norms that need to be abstract enough to be widely shared, the communal norms that are concrete enough to allow the members to understand without hesitation how they should behave in localized contexts are cumulatively cultivated along socializing process. Among the norms, sense of mutual obligation to incur intermittent costs for the whole community is a crucial norm for the sustainable development of the community. However, as a practical matter, membership control, mutual trust and short-term risk allocation may serve the communities in the short run, but they do not guarantee long-term accumulation of shared capital. As a result, the limits of community capital may need to be discussed once again, especially today when market liquidity is increasing, and its failures tend to become more apparent in a variety of areas. en-copyright= kn-copyright= en-aut-name=FujiiDaiji en-aut-sei=Fujii en-aut-mei=Daiji kn-aut-name=藤井大児 kn-aut-sei=藤井 kn-aut-mei=大児 aut-affil-num=1 ORCID= en-aut-name=OshimaTamako en-aut-sei=Oshima en-aut-mei=Tamako kn-aut-name=大島珠子 kn-aut-sei=大島 kn-aut-mei=珠子 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学学術研究院ヘルスシステム統合科学学域 affil-num=2 en-affil= kn-affil=国際医療福祉大学小田原保健医療学部看護学科 en-keyword=中間組織 kn-keyword=中間組織 en-keyword=内部組織の経済学 kn-keyword=内部組織の経済学 en-keyword=産業集積 kn-keyword=産業集積 en-keyword=コミュニティ・キャピタル kn-keyword=コミュニティ・キャピタル END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2018 dt-pub=20180323 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Newsletter from Course for Prospective Museum Workers, Faculty of Letters, Okayama University kn-title=学芸員課程 Newsletter 第10号 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=光本順 kn-aut-sei=光本 kn-aut-mei=順 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=三井絵莉子 kn-aut-sei=三井 kn-aut-mei=絵莉子 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=山岡隆太 kn-aut-sei=山岡 kn-aut-mei=隆太 aut-affil-num=3 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=田中陽子 kn-aut-sei=田中 kn-aut-mei=陽子 aut-affil-num=4 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=泉岳志 kn-aut-sei=泉 kn-aut-mei=岳志 aut-affil-num=5 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=大島友子 kn-aut-sei=大島 kn-aut-mei=友子 aut-affil-num=6 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=片山由奈 kn-aut-sei=片山 kn-aut-mei=由奈 aut-affil-num=7 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=額田千夏 kn-aut-sei=額田 kn-aut-mei=千夏 aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=文学部 affil-num=2 en-affil= kn-affil=文学部 哲学芸術学専修コース affil-num=3 en-affil= kn-affil=文学部 歴史文化学専修コース affil-num=4 en-affil= kn-affil=文学部 言語文化学専修コース affil-num=5 en-affil= kn-affil=文学部 哲学芸術学専修コース affil-num=6 en-affil= kn-affil=文学部 行動科学専修コース affil-num=7 en-affil= kn-affil=文学部 芸術学・美術史分野 affil-num=8 en-affil= kn-affil=文学部 歴史学・考古学分野 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230324 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=日本における性別と年齢ごとの性別違和の有病割合: ユトレヒト性別違和スケールを用いた人口ベースのインターネット調査 kn-title=Prevalence of Gender Dysphoria by Gender and Age in Japan: A Population-Based Internet Survey Using the Utrecht Gender Dysphoria Scale en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OSHIMAYoshitaka en-aut-sei=OSHIMA en-aut-mei=Yoshitaka kn-aut-name=大島義孝 kn-aut-sei=大島 kn-aut-mei=義孝 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=134 cd-vols= no-issue=1 article-no= start-page=22 end-page=27 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Developing a scale to measure nurses' difficulty related to the treatment of gender dysphoric patients kn-title=看護師の性別違和への関わりにくさについての尺度作成 en-subtitle= kn-subtitle= en-abstract= kn-abstract= This study aimed to develop a scale to measure the perceived difficulty experienced by nurses in treating and caring for patients diagnosed with gender dysphoria and examine its reliability and validity. We developed a 26-item preliminary scale through discussions with experts in gender dysphoria treatment. We administered a questionnaire including this scale to 1,010 nurses working at Okayama University Hospital and analyzed the data of 346 nurses who had been involved in the treatment of gender dysphoria and had no missing responses.
 A total of 20 items consisting of two factors, “relationship building” and “negative emotion for gender dysphoria,” were extracted by exploratory factor analysis, and we used them in the final version of the scale. Cronbach's alpha coefficient for the entire scale was 0.879, indicating a high degree of internal consistency.
 However, the correlations with a communication skills scale (ENDCOREs) and the Scale of Gender Conception were limited, and the external validity could not be proven. This scale may be useful for evaluating nursing practice and educational support for nurses; however, there is room for further study on the scale validation. en-copyright= kn-copyright= en-aut-name=MiyakeMaki en-aut-sei=Miyake en-aut-mei=Maki kn-aut-name=三宅麻希 kn-aut-sei=三宅 kn-aut-mei=麻希 aut-affil-num=1 ORCID= en-aut-name=OshimaYoshitaka en-aut-sei=Oshima en-aut-mei=Yoshitaka kn-aut-name=大島義孝 kn-aut-sei=大島 kn-aut-mei=義孝 aut-affil-num=2 ORCID= en-aut-name=NambaShihoko en-aut-sei=Namba en-aut-mei=Shihoko kn-aut-name=難波志穂子 kn-aut-sei=難波 kn-aut-mei=志穂子 aut-affil-num=3 ORCID= en-aut-name=MatsumotoYosuke en-aut-sei=Matsumoto en-aut-mei=Yosuke kn-aut-name=松本洋輔 kn-aut-sei=松本 kn-aut-mei=洋輔 aut-affil-num=4 ORCID= en-aut-name=HoriuchiMakiko en-aut-sei=Horiuchi en-aut-mei=Makiko kn-aut-name=堀内真希子 kn-aut-sei=堀内 kn-aut-mei=真希子 aut-affil-num=5 ORCID= en-aut-name=YamadaNorihito en-aut-sei=Yamada en-aut-mei=Norihito kn-aut-name=山田了士 kn-aut-sei=山田 kn-aut-mei=了士 aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Nursing, Okayama University Hospital kn-affil=岡山大学病院 看護部 affil-num=2 en-affil=Department of Neuropsychiatry, Okayama University Hospital kn-affil=岡山大学病院 精神科神経科 affil-num=3 en-affil=Department of Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil=岡山大学病院 新医療研究開発センター affil-num=4 en-affil=Department of Gender Center, Okayama University Hospital kn-affil=岡山大学病院 ジェンダーセンター affil-num=5 en-affil=Department of Medical Support, Clinical Psychology section, Okayama University Hospital kn-affil=岡山大学病院 医療技術部 臨床心理部門 affil-num=6 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil=岡山大学学術研究院医歯薬学域 精神神経病態学 en-keyword=性別違和 (gender dysphoria) kn-keyword=性別違和 (gender dysphoria) en-keyword=関わりにくさ (difficulty in relating) kn-keyword=関わりにくさ (difficulty in relating) en-keyword=コミュニケーション (communication) kn-keyword=コミュニケーション (communication) en-keyword=性差観 (gender conception) kn-keyword=性差観 (gender conception) END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue=1 article-no= start-page=1 end-page=14 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200327 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The meaning of “independence” and “burden” from FUKUZAWA Yukichi’s viewpoint kn-title=福沢諭吉における「独立」と「負担」 一家族・介護・老いを考える端緒として一 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=ShimadaYuichiro en-aut-sei=Shimada en-aut-mei=Yuichiro kn-aut-name=島田雄一郎 kn-aut-sei=島田 kn-aut-mei=雄一郎 aut-affil-num=1 ORCID= affil-num=1 en-affil=National Institute of Technology, Oshima College kn-affil=大島商船高等専門学校 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year= dt-pub= dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Canna indica L. var. flava (Roscoe) Baker kn-title=キバナダンドク en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-keyword=カンナ科 (Cannaceae) kn-keyword=カンナ科 (Cannaceae) END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year= dt-pub= dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Fimbristylis diphylloides Makino kn-title=クロテンツキ en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-keyword=カヤツリグサ科 (Cyperaceae) kn-keyword=カヤツリグサ科 (Cyperaceae) END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year= dt-pub= dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Cyperus nipponicus Franch. et Sav. kn-title=アオガヤツリ en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-keyword=カヤツリグサ科 (Cyperaceae) kn-keyword=カヤツリグサ科 (Cyperaceae) END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year= dt-pub= dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Cyperus difformis L. kn-title=タマガヤツリ en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-keyword=カヤツリグサ科 (Cyperaceae) kn-keyword=カヤツリグサ科 (Cyperaceae) END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year= dt-pub= dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Emilia sonchifolia (L.)

Recently, depression with Lewy body pathology before the appearance of parkinsonism and cognitive dysfunction has been drawing attention. Low cardiac metaiodobenzylguanidine (MIBG) uptake is helpful for early differentiation of Lewy body disease (LBD) from late-onset psychiatric disorders even before parkinsonism or dementia appears. In this study, we used MIBG uptake as a tool in suspected LBD, and evaluated the relationship of MIBG results to clinical characteristics and depressive symptoms.
METHODS:
Fifty-two elderly inpatients with depression were included in this study. The Hamilton Depression Rating Scale (HDRS) was administered at admission, and 123 I-MIBG cardiac scintigraphy was performed. Of 52 patients, 38 had normal and 14 had reduced MIBG uptake.
RESULTS:
Correlation analyses of the late phase heart-to-mediastinum (H/M) ratio on the MIBG test and each item of the HDRS revealed that the H/M ratio was significantly correlated with scores of 'agitation', 'anxiety-somatic', and 'retardation' on the HDRS. Mean HDRS composite scores of 'somatic and psychic anxiety (Marcos)' and 'somatic anxiety/somatization factor (Pancheri)' were higher in the low uptake group than in the normal uptake group.
CONCLUSION:
Elderly patients with depression who manifested an obvious somatic anxiety tend to show low MIBG uptake, and are more likely to have Lewy body pathology. en-copyright= kn-copyright= en-aut-name=TakenoshitaShintaro en-aut-sei=Takenoshita en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TeradaSeishi en-aut-sei=Terada en-aut-mei=Seishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OshimaEtsuko en-aut-sei=Oshima en-aut-mei=Etsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamaguchiMegumi en-aut-sei=Yamaguchi en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HayashiSatoshi en-aut-sei=Hayashi en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HinotsuKenji en-aut-sei=Hinotsu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=EsumiSatoru en-aut-sei=Esumi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShinyaTakayoshi en-aut-sei=Shinya en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamadaNorihito en-aut-sei=Yamada en-aut-mei=Norihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Pharmacy, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pediatric Radiology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Neuropsychiatry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=depression kn-keyword=depression en-keyword=elderly kn-keyword=elderly en-keyword=Lewy body disease kn-keyword=Lewy body disease en-keyword=metaiodobenzylguanidine kn-keyword=metaiodobenzylguanidine en-keyword=somatic anxiety kn-keyword=somatic anxiety END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year= dt-pub= dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Fallopia convolvulus (L.)

The Head and Neck Cancer Center was established at Okayama University Hospital in 2012.  This Center was the first of its kind at a national university hospital in Japan.  At the Center, 174 operations on head and neck carcinomas and 96 reconstructive operations were performed in 2014( fiscal year).  Medical and dental collaborative operations have been increasing almost every year since the 2005 fiscal year. There were 45 collaborative operations in the 2014 fiscal year, which included 30 cases of bone or metal plate reconstruction or plate reinforcement of the jaws.  There were 76 medical and dental collaborative operations in the 7 years before the establishment of the Center, with a mean of 10.9 operations per year. Since the establishment of the Center, there have been 112 cases over 3 years with a mean of 37.3 operations per year.

Here we report a case we recently encountered, and we review 16 cases reported in Japan. An 82-year-old Japanese woman was admitted to our hospital complaining of abdominal pain and heartburn. An endoscopic examination revealed a Type 2 tumor in the descending limb of the duodenum, and endoscopically obtained specimens revealed a poorly differentiated adenocarcinoma. We performed a curative pancreatoduodenectomy with lymph node resection, and the surgical specimen revealed that the duodenum was the primary site of the mucinous adenocarcinoma. The patient is currently alive > 1 year after the operation without any evidence of recurrence. Of the 16 patients reviewed, all patients had advanced tumors those depth were T3-T4. 9 patients had lymph node metastasis and 4 patients had peritoneal dissemination at the time of surgery. Since mucinous adenocarcinoma of the duodenum is often progressive cancer at a diagnosis, which is tend to have a worse prognosis than other histological types. en-copyright= kn-copyright= en-aut-name=HamanoIkumi en-aut-sei=Hamano en-aut-mei=Ikumi kn-aut-name=浜野郁美 kn-aut-sei=浜野 kn-aut-mei=郁美 aut-affil-num=1 ORCID= en-aut-name=MatsumotoYusuke en-aut-sei=Matsumoto en-aut-mei=Yusuke kn-aut-name=松本祐介 kn-aut-sei=松本 kn-aut-mei=祐介 aut-affil-num=2 ORCID= en-aut-name=EndoYoshikatsu en-aut-sei=Endo en-aut-mei=Yoshikatsu kn-aut-name=遠藤芳克 kn-aut-sei=遠藤 kn-aut-mei=芳克 aut-affil-num=3 ORCID= en-aut-name=WatanabeNaoki en-aut-sei=Watanabe en-aut-mei=Naoki kn-aut-name=渡邊直樹 kn-aut-sei=渡邊 kn-aut-mei=直樹 aut-affil-num=4 ORCID= en-aut-name=KaiKyouhei en-aut-sei=Kai en-aut-mei=Kyouhei kn-aut-name=甲斐恭平 kn-aut-sei=甲斐 kn-aut-mei=恭平 aut-affil-num=5 ORCID= en-aut-name=SatoShizou en-aut-sei=Sato en-aut-mei=Shizou kn-aut-name=佐藤四三 kn-aut-sei=佐藤 kn-aut-mei=四三 aut-affil-num=6 ORCID= en-aut-name=WaniYoji en-aut-sei=Wani en-aut-mei=Yoji kn-aut-name=和仁洋治 kn-aut-sei=和仁 kn-aut-mei=洋治 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=姫路赤十字病院 外科 affil-num=2 en-affil= kn-affil=姫路赤十字病院 外科 affil-num=3 en-affil= kn-affil=姫路赤十字病院 外科 affil-num=4 en-affil= kn-affil=姫路赤十字病院 外科 affil-num=5 en-affil= kn-affil=姫路赤十字病院 外科 affil-num=6 en-affil= kn-affil=姫路赤十字病院 外科 affil-num=7 en-affil= kn-affil=姫路赤十字病院 病理診断科 en-keyword=原発性十二指腸癌(primary duodenal cancer) kn-keyword=原発性十二指腸癌(primary duodenal cancer) en-keyword=粘液癌(mucinous carcinoma) kn-keyword=粘液癌(mucinous carcinoma) en-keyword=膵頭十二指腸切除(pancreatoduodenectomy) kn-keyword=膵頭十二指腸切除(pancreatoduodenectomy) END start-ver=1.4 cd-journal=joma no-vol=127 cd-vols= no-issue=3 article-no= start-page=213 end-page=218 dt-received= dt-revised= dt-accepted= dt-pub-year=2015 dt-pub=20151201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A case report of giant ectopic pheochromocytoma conversion therapy with radioisotope therapy and chemotherapy followed by curative resection kn-title=術前内照射および化学療法が著効し,根治切除し得た巨大異所性褐色細胞腫の1例 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 46-year-old man was found to be positive for occult blood at a medical checkup and was revealed to have a 14-cm tumor on the right side of abdominal aorta by a subsequent abdominal CT scan. The endocrinology laboratory data showed elevations in the levels of serum noradrenaline, and ectopic pheochromocytoma was suspected. The tumor was compressing the inferior vena cava and portal vein, the superior mesenteric artery and the pancreas. Since it would be difficult to cure by operation, neoadjuvant therapy was started using radioisotope therapy by I-131 metaiodobenzylguanidine (131I-MIBG) and chemotherapy (CVD therapy ; cyclophosphamide, vincristine, dacarbazine). He was treated with three courses of radioisotope therapy and 16 courses of chemotherapy, which significantly reduced the tumor size. This made radical resection possible ; we were able to avoid the merger excision of great vessels and other organs. On pathological and immunopathological findings, the tumor was diagnosed as ectopic pheochromocytoma. Regarding the safety and curability of the treatment, neoadjuvant therapy may be useful in treating very large tumors that show invasion of other organs. en-copyright= kn-copyright= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name=安井和也 kn-aut-sei=安井 kn-aut-mei=和也 aut-affil-num=1 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name=楳田祐三 kn-aut-sei=楳田 kn-aut-mei=祐三 aut-affil-num=2 ORCID= en-aut-name=KumanoKenjiro en-aut-sei=Kumano en-aut-mei=Kenjiro kn-aut-name=熊野健二郎 kn-aut-sei=熊野 kn-aut-mei=健二郎 aut-affil-num=3 ORCID= en-aut-name=TabataMasahiro en-aut-sei=Tabata en-aut-mei=Masahiro kn-aut-name=田端雅弘 kn-aut-sei=田端 kn-aut-mei=雅弘 aut-affil-num=4 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name=大塚文男 kn-aut-sei=大塚 kn-aut-mei=文男 aut-affil-num=5 ORCID= en-aut-name=YagiTakahito en-aut-sei=Yagi en-aut-mei=Takahito kn-aut-name=八木孝仁 kn-aut-sei=八木 kn-aut-mei=孝仁 aut-affil-num=6 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name=藤原俊義 kn-aut-sei=藤原 kn-aut-mei=俊義 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 affil-num=2 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 affil-num=3 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 affil-num=4 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 affil-num=5 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 affil-num=6 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 affil-num=7 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 en-keyword=異所性褐色細胞腫(ectopic pheochromocytoma) kn-keyword=異所性褐色細胞腫(ectopic pheochromocytoma) en-keyword=化学療法(chemo therapy) kn-keyword=化学療法(chemo therapy) en-keyword=131I-MIBG kn-keyword=131I-MIBG END start-ver=1.4 cd-journal=joma no-vol=126 cd-vols= no-issue=2 article-no= start-page=99 end-page=102 dt-received= dt-revised= dt-accepted= dt-pub-year=2014 dt-pub=20140801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The 2013 Incentive Award of the Okayama Medical Association in Neuroscience (2013 Niimi Prize) kn-title=平成25年度岡山医学会賞 脳神経研究奨励賞(新見賞) en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OshimaEtsuko en-aut-sei=Oshima en-aut-mei=Etsuko kn-aut-name=大島悦子 kn-aut-sei=大島 kn-aut-mei=悦子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学病院 精神科神経科 END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue=4 article-no= start-page=1 end-page=2 dt-received= dt-revised= dt-accepted= dt-pub-year=1949 dt-pub=19491010 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the biological control of plant diseases by the utilization of antagonistic organisms on the pathogenes.

report herein a case of mesenteric Castleman's disease which was confirmed on pathology. A 60-year-old man was admitted to our hospital complaining of abdominal pain. On the physical examination, there was no palpable mass. Computed tomography findings and magnetic resonance imaging revealed a well circumscribed, lobulated round mass on the right side of the superior mesenteric vein. Laparoscopic surgery for the mesenteric tumor was carried out to obtain a definite diagnosis and treatment. In the operative field, the mass was located on the ascending colic mesentery and measured about 3 cm in size. It was solid and surrounded by a thin fibrous capsule. The histological diagnosis of the mesenteric tumor was hyaline vascular type Castleman's disease. The postoperative course of the patient was uneventful, and he was discharged on the 10th postoperative day. en-copyright= kn-copyright= en-aut-name=NishieManabu en-aut-sei=Nishie en-aut-mei=Manabu kn-aut-name=西江学 kn-aut-sei=西江 kn-aut-mei=学 aut-affil-num=1 ORCID= en-aut-name=OtsukaShinya en-aut-sei=Otsuka en-aut-mei=Shinya kn-aut-name=大塚真哉 kn-aut-sei=大塚 kn-aut-mei=真哉 aut-affil-num=2 ORCID= en-aut-name=TomodaJun en-aut-sei=Tomoda en-aut-mei=Jun kn-aut-name=友田純 kn-aut-sei=友田 kn-aut-mei=純 aut-affil-num=3 ORCID= en-aut-name=FujiwaraKeishi en-aut-sei=Fujiwara en-aut-mei=Keishi kn-aut-name=藤原敬士 kn-aut-sei=藤原 kn-aut-mei=敬士 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=国立病院機構福山医療センター 外科 affil-num=2 en-affil= kn-affil=国立病院機構福山医療センター 外科 affil-num=3 en-affil= kn-affil=国立病院機構福山医療センター 内科 affil-num=4 en-affil= kn-affil=光生病院 内科 en-keyword=結腸間膜 (mesocolon) kn-keyword=結腸間膜 (mesocolon) en-keyword=Castleman病 (Castleman's disease) kn-keyword=Castleman病 (Castleman's disease) en-keyword=腹腔鏡手術 (laparoscopic surgery) kn-keyword=腹腔鏡手術 (laparoscopic surgery) END start-ver=1.4 cd-journal=joma no-vol=61 cd-vols= no-issue=6-7 article-no= start-page=131 end-page=134 dt-received= dt-revised= dt-accepted= dt-pub-year=1949 dt-pub=19490831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=温泉の效用 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=大島良雄 kn-aut-sei=大島 kn-aut-mei=良雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大學放射能泉研究所 END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=15 end-page=20 dt-received= dt-revised= dt-accepted= dt-pub-year=1953 dt-pub=195309 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=INDICE DE NUTRITION AND OXIDATIOM-REDUCTION POTENIAL OF MINERAL WATERS kn-title=温泉水のIndice de nutritionと酸化還元電位 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Indice de nutrition (Pech), indice de nutrition simplifié (Rimattei), membrane potential difference of human skin, and oxidation-reduction potential of several mineral watem were measured.

But the highest radon content of the waters used at that time was about 1000×10(-10) Curie units per liter. Recently a more highly radioactive spring was found in Misasa, its radon content being 3000-4000×l0(-10) Curie units per liter, though very feebly mineralized (under 0.5 g per liter) and cold. Therefore the hypoglycaemic effect of this newly discovered water was, investigated in rabbits and compared with the effects of two other thermal waters in Tottori Prefecture and of plain water as a control. Twenty cc. of ten per cent glucofoe solution in thermal waters or in plain water per kilogram of bodyweight was administered to the rabitts by stomach tube and blood sugar level was determined before, 30, 60, 120, and 180 minutes after the administration. All of the three thermal waters decreased the glycaemia significantly as compared the results with plain water control. en-copyright= kn-copyright= en-aut-name=OshimaYoshio en-aut-sei=Oshima en-aut-mei=Yoshio kn-aut-name=大島良雄 kn-aut-sei=大島 kn-aut-mei=良雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所内科 END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue= article-no= start-page=18 end-page=20 dt-received= dt-revised= dt-accepted= dt-pub-year=1950 dt-pub=19500725 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies of the radio-active springs.

Blood samples were taken from cubital vein before, 1, 2, 4, 6, 24, 48, and 72 hours after the intake of the vitriol water. Copper, zinc, nickel and cobalt contents of the blood samples were measured by Ashizawa' s dithizone- chromatographic method. It was shown that copper, nickel, and cobalt contents of blood rose unexpectedly high temporarily, in a manner that did not correspond to their amount in the given mineral water. So that the mobilization of copper, nickel, and cobalt in the body after the intake of the mineral IVrter was susrected.

Radon content of 166 thermal waters in IWAI, TOTTORI YOSHIOKA, HAMAMURA, TOGO, SEKIGANE, MISASA, and KAlKE Hot Springs was measured by I. M. Fontactoscope in the years 1950-1951. Of which 66 samples showed a radon content over 30×10(-10) curie units per liter. Namely, 50 springs in Misasa, 6 in Sekigane, 9 in Hamamura, and one in Togo belonged to the radioactive spring in the definition by Ministry of Social Welfare. The highest Radon content (1150×10(10) curie units per liter) was recorded in Hisuino-Yu in Misasa, where five springs had a radon content over 360×10(-10) curie units per liter. 2. No marked difference was proved between the results obtained this time and the data in the former reports concerning the radon content of these thermal springs. 3. Radon content proved higher in the springs which issue from granite than in the springs of other districts. No definite relation was proved between the radon content and water temperature. The radon content was generally high in simple thermals or in weak sodium chloride springs, low in sulfated springs and in saline springs which had a comparatively high sulfate content. en-copyright= kn-copyright= en-aut-name=OshimaYoshio en-aut-sei=Oshima en-aut-mei=Yoshio kn-aut-name=大島良雄 kn-aut-sei=大島 kn-aut-mei=良雄 aut-affil-num=1 ORCID= en-aut-name=YamadaNaoharu en-aut-sei=Yamada en-aut-mei=Naoharu kn-aut-name=山田尚春 kn-aut-sei=山田 kn-aut-mei=尚春 aut-affil-num=2 ORCID= en-aut-name=MifuneMasaaki en-aut-sei=Mifune en-aut-mei=Masaaki kn-aut-name=御船政明 kn-aut-sei=御船 kn-aut-mei=政明 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所 affil-num=2 en-affil= kn-affil=岡山大学温泉研究所 affil-num=3 en-affil= kn-affil=岡山大学温泉研究所 END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue= article-no= start-page=1 end-page=18 dt-received= dt-revised= dt-accepted= dt-pub-year=1956 dt-pub=195601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=REPORT OF THE CHEMICAL ANALYSIS OF MISASA HOT SPRINGS, TOTTORI PREFECTURE kn-title=鳥取県三朝温泉調査報告 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The water samples of 55 springs of Misasa were analysed in the years 1950~1951. The temperatures of the waters ranged from 44° to 85° C. Radon content ranged from 34.1 to 2360×10(-10) curies per liter. pH 6.2~7.5. Evaporation residue: 534~1940 mg/kg. K(+) :10.4~47.3mg/kg. Na(+) : 140.4~574mg/kg. Ca(2+) : 7.56~49.06mg/kg. Mg(2+) : 0.11~15.3mg/kg.. Fe(2+) : 0.10~0.67mg/kg. Cl(-) : 138~854mg/kg. SO(4)(2-) : 29.2~187mg/kg. HCO(3)(-) : 74.8~370mg/kg. HBO(2)(-) : 1.80~19.6mg/kg. S(2)O(3)(2-) : o.62~3.69mg/kg. Radon sources seem to exist at shallow places under the ground and the radon in the thermal wacer is supposed to have been derive partly from the ground water which also contains considerable amount of radon. A close linear correlation (r=0.751) was proved between the sulfate and the chloride ion contents. en-copyright= kn-copyright= en-aut-name=OshimaYoshio en-aut-sei=Oshima en-aut-mei=Yoshio kn-aut-name=大島良雄 kn-aut-sei=大島 kn-aut-mei=良雄 aut-affil-num=1 ORCID= en-aut-name=MifuneMasaaki en-aut-sei=Mifune en-aut-mei=Masaaki kn-aut-name=御船政明 kn-aut-sei=御船 kn-aut-mei=政明 aut-affil-num=2 ORCID= en-aut-name=YamadaNaoharu en-aut-sei=Yamada en-aut-mei=Naoharu kn-aut-name=山田尚春 kn-aut-sei=山田 kn-aut-mei=尚春 aut-affil-num=3 ORCID= en-aut-name=UeyamaAkiko en-aut-sei=Ueyama en-aut-mei=Akiko kn-aut-name=上山昭子 kn-aut-sei=上山 kn-aut-mei=昭子 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所 affil-num=2 en-affil= kn-affil=岡山大学温泉研究所 affil-num=3 en-affil= kn-affil=鳥取県衛生部 affil-num=4 en-affil= kn-affil=鳥取県衛生部 END start-ver=1.4 cd-journal=joma no-vol=68 cd-vols= no-issue=3 article-no= start-page=951 end-page=956 dt-received= dt-revised= dt-accepted= dt-pub-year=2005 dt-pub=20050811 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Kinetic-spectrophotometric method for the determination of trace amounts of bromide in seawater en-subtitle= kn-subtitle= en-abstract= kn-abstract=

A novel simple, sensitive and rapid kinetic-spectrophotornetric method is proposed for the determination of trace amounts of bromide. The method is based on its catalytic effect on the oxidation of methylene blue (MB) by hydrogen peroxide in strongly acidic solution. The oxidation reaction is activated by large amounts of chloride and can be monitored spectrophotometrically by measuring the decrease in the absorbance of MB at 746 run. The determination of bromide is performed by a fixed-time method at the first 100 s from the initiation of the reaction. Unlike other kinetic-spectrophotornetric methods for the determination of bromide, the proposed method does not require heating the solution. Bromide can be determined in the range from 80 to 960 mu g l(-1) with the detection limit of 35 mu g l(-1). The relative standard deviation of ten replicate determination of 480 mu g l(-1) bromide was 1.4%. The influence of potential interfering ions was studied. The proposed method was satisfactorily applied to the determination of bromide in seawater without interfering effect from chloride ion.

On-line preconcentration system for the selective, sensitive and simultaneous determination of chromium species was investigated. Dual minicolumns containing chelating resin were utilized for the speciation and preconcentration of Cr(III) and Cr(VI) in water samples. In this system, Cr(III) was collected on first column packed with iminodiacetate resin. Cr(VI) in the effluent from the first column was reduced to Cr(III), which was collected on the second column packed with iminodiacetate resin. Hydroxyammonium chloride was examined as a potential reducing agent for Cr(VI) to Cr(III). The effects of pH, sample flow rate, column length, and interfering ions on the recoveries of Cr(III) were carefully studied. Five millilitres of a sample solution was introduced into the system. The collected species were then sequentially washed by 1 M ammonium acetate, eluted by 2 M nitric acid and measured by ICP-AES. The detection limit for Cr(III) and Cr(VI) was 0.08 and 0.15 mu g l-1, respectively. The total analysis time was about 9.4 min.

In the present study, ultratrace amounts of silver collected on the resin were eluted and determined by ICP-MS. The resin packed in a 1 mL mini column could adsorb silver selectively and quantitatively at a flow rate of 2 mL min(-1) in the wide pH range from 1 to 8, and silver adsorbed on the resin could be easily recovered by passing 1 M nitric acid as an eluent into the column. High adsorption capacity for silver at pH 5, 0.37 mmol mL(-1) of the resin, was achieved, and t(1/2) of the adsorption is less than 5 min. The effect of chloride on the collection of silver was examined by varying chloride concentrations from 10(-4) to 0.75 M; the results showed that the present resin can be used for the collection/concentration of ultratrace amounts of silver in natural waters, as well as seawater. To ensure the accuracy and the precision of the method, CASS-4 near shore seawater reference material from the NRCC has been analyzed. This is not a certified SRM for silver, but has been used for comparative silver analysis by several groups, who report very similar results to those that are reported here. The developed method using ethylenediamine-type chitosan resin gives 0.7 pg mL(-1) of the detection limit when 50-fold enrichment was used. The proposed method was successfully applied to the determination of silver in tap, river, and seawater samples. en-copyright= kn-copyright= en-aut-name=KatarinaRosi Ketrin en-aut-sei=Katarina en-aut-mei=Rosi Ketrin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=2 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=3 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=4 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University en-keyword=Chelating resin kn-keyword=Chelating resin en-keyword=Chitosan kn-keyword=Chitosan en-keyword=Determination of silver kn-keyword=Determination of silver en-keyword=Environmental water samples kn-keyword=Environmental water samples en-keyword=ICP-MS kn-keyword=ICP-MS END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue=3 article-no= start-page=263 end-page=268 dt-received= dt-revised= dt-accepted= dt-pub-year=2005 dt-pub=200503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trace and ultratrace analysis of purified water samples and hydrogen peroxide solutions for phosphorus by flow-injection method en-subtitle= kn-subtitle= en-abstract= kn-abstract=

After the elution of the collected elements on the resin with 1M HNO3, the eluates were measured by inductively coupled plasma-mass spectrometry (ICP-MS). The CCTS-DHBA resin can adsorb several metal cations and several oxoanionic elements at appropriate pH. Among these metal ions, uranium shows an excellent adsorption behavior on this resin. Uranium as UO22+ species can be adsorbed on the resin by chelating mechanism with adsorption capacity of 330 mg g(-1) resin. Through the column treatment, the complete removal of large amounts of alkali and alkaline earth matrices without any loss of adsorption efficiency over prolonged usage were achieved with this resin. The CCTS-DHBA resin was applied to the adsorption/collection of uranium in tap water, river water and seawater samples with satisfactory results. The validation of the proposed method was carried out by analyzing uranium in the standard reference materials of SLRS-4, CASS-4, and NASS-5 after passing through the CCTS-DHBA resin, and the results showed good agreement with the certified values. en-copyright= kn-copyright= en-aut-name=SabarudinAkhmad en-aut-sei=Sabarudin en-aut-mei=Akhmad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HakimLukman en-aut-sei=Hakim en-aut-mei=Lukman kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OshitaKoji en-aut-sei=Oshita en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GaoYun Hua en-aut-sei=Gao en-aut-mei=Yun Hua kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=2 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=3 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=4 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=5 en-affil= kn-affil=Department of International Conservation Studies, Faculty of International and Industrial Studies, Kibi International University affil-num=6 en-affil= kn-affil=Technical Institute of Physics and Chemistry, Chinese Academy of Sciences affil-num=7 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University en-keyword=Chitosan resin kn-keyword=Chitosan resin en-keyword=3,4-dihydroxybenzoic acid kn-keyword=3,4-dihydroxybenzoic acid en-keyword=Uranium kn-keyword=Uranium en-keyword=Adsorption kn-keyword=Adsorption en-keyword=Water kn-keyword=Water en-keyword=Inductively coupled plasma-mass spectrometry kn-keyword=Inductively coupled plasma-mass spectrometry END start-ver=1.4 cd-journal=joma no-vol=588 cd-vols= no-issue=1 article-no= start-page=73 end-page=81 dt-received= dt-revised= dt-accepted= dt-pub-year=2007 dt-pub=20070404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of novel chitosan resin derivatized with serine diacetic acid moiety and its application to on-line collection/concentration of trace elements and their determination using inductively coupled plasma-atomic emission spectrometry en-subtitle= kn-subtitle= en-abstract= kn-abstract=A novel chelating resin functionalized with serine diacetic acid moiety was synthesized by using chitosan as base material, and applied to the collection/concentration of trace elements in environmental water samples, followed by the determination using inductively coupled plasma-atomic emission spectrometer (ICP-AES).

The method is based on the formation of an ion associate of molybdosilicate with malachite green (MG) and the collection of the ion associate on a tiny membrane filter (diameter: 5 mm, and effective filtering diameter: 1 mm). The ion associate formed on the membrane filter is dissolved together with the membrane filter in 1 ml of methyl cellosolve (MC) and the absorbance of MC solution is measured at 627 nm by a flow injection-spectrophotometric detection technique. In this method, silicate in the original sample (ultrapurified water) is concentrated as the ion associate into a small volume of MC to get high sensitivity. As sample concentration takes place, the small amounts of silicate contained in the reagents used also become concentrated as the ion associate into MC. The original sample volumes are varied and evaporated to an identical volume. Therefore, the reagent added is fixed to the same volume. The absorbance increase linearly with increase in the original sample volume will be due only to silicate in the original samples (ultrapurified water). The resulting slopes obtained by varying the sample volumes are compared with the slope of the calibration graph, and thus named the slope comparison method (SCM). The SCM facilitates a more sensitive and accurate evaluation of silicate concentration in the samples than either common calibration method (CCM) or standard addition method (SAM) because it compensates for the influence of trace amounts of silicate contained in chemicals, reagent solution and solvent used. The calibration graph was constructed from 0 to 0.25 ng ml(-1) of Si and the detection limit was 10 pg ml(-1) (ppt) when 30 ml of samples was used. The standard deviation and relative standard deviation from six measurements of the reagent blanks were 0.0012 and 3.5%, respectively. en-copyright= kn-copyright= en-aut-name=SabarudinAkhmad en-aut-sei=Sabarudin en-aut-mei=Akhmad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=2 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=3 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University en-keyword=slope comparison method kn-keyword=slope comparison method en-keyword=ultrapurified water kn-keyword=ultrapurified water en-keyword=ion associate kn-keyword=ion associate en-keyword=molybdosilicate kn-keyword=molybdosilicate en-keyword=malachite green kn-keyword=malachite green en-keyword=membrane filter kn-keyword=membrane filter END start-ver=1.4 cd-journal=joma no-vol=542 cd-vols= no-issue=2 article-no= start-page=207 end-page=215 dt-received= dt-revised= dt-accepted= dt-pub-year=2005 dt-pub=20050629 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Synthesis of chitosan resin possessing 3,4-diamino benzoic acid moiety for the collection/concentration of arsenic and selenium in water samples and their measurement by inductively coupled plasma-mass spectrometry en-subtitle= kn-subtitle= en-abstract= kn-abstract=A chitosan resin functionalized with 3,4-diamino benzoic acid (CCTS-DBA resin) was newly synthesized by using a cross-linked chitosan (CCTS) as base material.

Arsenic(V) could be retained on the CCTS-DBA resin at pH 3 as an oxoanion of H(2)ASO(4)(-). Selenium(VI) is strongly adsorbed at pH 2 and pH 3 as an oxoanion of SeO42-. while selenium(IV) as HSeO3- is adsorbed on the resin at pH 3.

A novel fluorophotometric method for formaldehyde determination in environmental waters was developed: the method does not require any enrichment procedures. A flow-injection analysis method for the spectrofluorometric determination of formaldehyde in waters, which is based on the reaction of formaldehyde with acetoacetanilide and ammonia, is proposed. The proposed method shows a good linearity from 0.50 to 40 x 10(-7) M, and the limit of detection (LOD) of 3 x 10(-9) M (0.09 ppb) is achievable. The sample throughput is 15 h(-1). One of the main advantages in the proposed method is that the reaction can be carried out at room temperature without any heating system. The effect of various interferences possibly present in the real water samples was investigated. Most cations and anions, as well as organic compounds, do not interfere with the determination of formaldehyde in environmental water samples. The proposed method is very simple, rapid, less expensive, and highly sensitive, and can be applied to the environmental water samples, such as rain, tap water and river water, at low concentration levels without any enrichment procedure.

A novel chitosan-based chelating resin modified with tris(2-aminoethyl)amine moiety (CCTS-TAA) was synthesized. and its characteristics in the collection/concentration of mercury was examined. The synthesized resin showed good adsorption toward mercury in a wide pH range, and the adsorbed mercury can be easily eluted by using 2 M HNO3 without any addition of complexing agent. The resin was then packed in a mini-column and the mini-column was installed on a computer-controlled automated-pretreatment (Auto-Pret) system coupled with inductively coupled plasma-atomic emission spectroscopy (ICP-AES) for on-line mercury collection and determination at trace level.

Ion association between inorganic anions and symmetrical tetraalkylammonium ions, R4N+ (R = Me, Et, Pr, n-Bu, n-Am, and 2-methyl butyl {isoamyl = iAm}) was investigated using ordinary silica capillary by capillary zone electrophoresis. An improved version of the Williams-Vigh method was used for the first time to measure the mobilities of the inorganic anions. Plots of log K-ass against log dielectric constant in various media, revealed a smaller change in K-ass compared to dielectric constant. These plots suggest that the Bjerrum's equation is inadequate in accounting for the associations of ions in a CZE setup.

A novel chitosan-based resin functionalized with threonine moiety was synthesized, and applied to the collection/concentration of Mo, V and Cu in environmental water samples, followed by their determination using inductively coupled plasma-atomic emission spectrometer (ICP-AES). The synthesized resin, cross-linked chitosan-threonine (CCTS-Thr), showed good adsorption behavior toward trace amounts of Mo, V and Cu in a wide pH range. The adsorbed elements can be easily eluted using 2 mol L-1 of nitric acid, and their recoveries were found to be 90-100%. The CCTS-Thr was packed in a mini-column, which was then installed in a computer-controlled auto-pretreatment system (Auto-Pret System) for on-line trace elements collection and determination by ICP-AES. Experimental parameters related to the improvement of sensitivity and reproducibility were optimized. The limits of detection (LODs) for target metals were found to be in sub-ppb level. The proposed method with CCTS-Thr resin was successfully applied to the determination of Mo, V and Cu in environmental water samples. The recovery test showed that common matrices which exist in environmental water samples did not interfere with the determination.

A chitosan resin functionalized with 3-nitro-4-amino benzoic acid moiety (CCTS-NABA resin) was newly synthesized for the collection/concentration of trace molybdenum by using cross-linked chitosan (CCTS) as base material. The carboxyl group of the moiety was chemically attached to amino group of cross-linked chitosan through amide bond formation. The adsorption behavior of molybdenum as well as other 60 elements on the resin was examined by passing the sample solutions through a mini-column packed with the resin. After the elution of the elements collected on the resin with 1 M HNO3, the eluates were analyzed by inductively coupled plasma-mass spectrometry (ICP-MS) and atomic emission spectrometry (ICP-AES).
The CCTS-NABA resin can adsorb several metal ions, such as vanadium, gallium, arsenic, selenium, silver, bismuth, thorium, tungsten, tin, tellurium, copper, and molybdenum at appropriate pHs. Among these metal ions, only molybdenum could be adsorbed almost completely on the resin at acidic regions. An excellent selectivity toward molybdenum could be obtained at pH 3-4. The adsorption capacity of CCTS-NABA resin for Mo(VI) was 380 mg g(-1) resin. Through the column pretreatment, alkali and alkaline earth metals in river water and seawater samples were successfully removed.
The CCTS-NABA resin was applied to the adsorption/collection of molybdenum in river water and seawater samples. The concentrations of molybdenum in river water samples were found in the range of 0.84 and 0.95 ppb (ng g(-1)), whereas molybdenum in seawater was about 9 ppb. The validation of the proposed method was carried out by determining molybdenum in the certified reference materials of SLRS-4, CASS-4, and NASS-5 after passing through the CCTS-NABA resin; the results showed good agreement with the certified-values.

A novel spectrophotometric reaction system was developed for the determination of nitrite as well as nitrate in water samples, and was applied to a flow-injection analysis (FIA). The spectrophotometric flow-injection system coupled with a copperised cadmium reductor column was proposed. The detection was based on the nitrosation reaction between nitrite ion and phloroglucinol (1,3,5-trihydroxybenzene), a commercially available phenolic compound. Sample injected into a carrier stream was split into two streams at the Y-shaped connector. One of the streams merged directly and reacted with the reagent stream: nitrite ion in the samples was detected. The other stream was passed through the copperised cadmium reductor column, where the reduction of nitrate to nitrite occurred, and the sample zone was then mixed with the reagent stream and passed through the detector: the sum of nitrate and nitrite was detected. The optimised conditions allow a linear calibration range of 0.03-0.30 mug NO2--N ml(-1) and 0.10-1.00 mug NO3--N ml(-1). The detection limits for nitrite and nitrate, defined as three times the standard deviation of measured blanks are 2.9 ng NO2--N ml(-1) and 2.3 ng NO3--N ml(-1), respectively. Up to 20 samples can be analyzed per hour with a relative standard deviation of less than 1.5%. The proposed method could be applied successfully to the simultaneous determination of nitrite and nitrate in water samples.

A new chelating resin using chitosan as a base material was synthesized. Functional moiety of 2-amino-5-hydroxy benzoic acid (AHBA) was chemically bonded to the amino group of cross-linked chitosan (CCTS) through the arm of chloromethyloxirane (CCTS-AHBA resin). Several elements, such as Ag, Be, Cd, Co, Cu, Ni, Ph, U, V, and rare earth elements (REEs), could be adsorbed on the resin. To use the resin for on-line pretreatment, the resin was packed in a mini-column and installed into a sequential-injection/automated pretreatment system (Auto-Pret System) coupled with inductively coupled plasma-atomic emission spectrometry (ICP-AES). The sequential-injection/automated pretreatment system was a laboratory-assembled, and the program was written using Visual Basic software. This system can provide easy operation procedures, less reagent consumption, as well as less waste production. Experimental variables considered as effective factors in the improvement sensitivity, such as an eluent concentration, a sample and an eluent flow rate, pH of samples, and air-sandwiched eluent were carefully optimized. The proposed system provides excellent on-line collection efficiency, as well as high concentration factors of analytes in water samples, which results in highly sensitive detection of ultra-trace and trace analysis. Under the optimal conditions, the detection limits of 24 elements examined are in the range from ppt to sub-ppb levels. The proposed method was validated by using the standard reference material of a river water, SLRS-4, and the applicability was further demonstrated to the on-line collection/concentration of trace elements, such as Ag, Be, Cd, Co, Cu, Ni, Ph, U, V, and REEs in water samples.

Chitosan resins modified with amino acids, such as glycine, valine, leucine, and serine, were synthesized for investigating the adsorption behavior of cationic and anionic species, and showed good abilities for the adsorption of trace elements in aquatic media as follows: glycine for lanthanoids at pH 7, leucine for molybdenum at pH 1 - 5, serine for uranium at pH 2 - 7, and amino acids for bismuth at pH 1 - 7. Cationic and anionic species could be adsorbed by a chelating mechanism and an anion-exchange mechanism.

A chelating resin, cross-linked chitosan modified with the glycine moiety (glycine-type chitosan resin), was developed for the collection and concentration of bismuth in aquatic samples for ICP-MS measurements. The adsorption behavior of bismuth and 55 elements on glycine-type chitosan resin was systematically examined by passing a sample solution containing 56 elements through a mini-column packed with the resin (wet volume; I ml). After eluting the elements adsorbed on the resin with nitric acid, the eluates were measured by ICP-MS. The glycine-type chitosan resin could adsorb several cations by a chelating mechanism and several oxoanions by an anion-exchange mechanism. Especially, the resin could adsorb almost 100% Bi(III) over a wide pH region from pH 2 to 6. Bismuth could be strongly adsorbed at pH 3, and eluted quantitatively with 10 ml of 3 M nitric acid. A column pretreatment method with the glycine-type chitosan resin was used prior to removal of high concentrations of matrices in a seawater sample and the preconcentration of trace bismuth in river water samples for ICP-MS measurements. The column pretreatment method was also applied to the determination of bismuth in real samples by ICP-MS. The LOD of bismuth was 0.1 pg ml(-1) by 10-fold column preconcentration for ICP-MS measurements. The analytical results for bismuth in sea and river water samples by ICP-MS were 22.9 +/- 0.5 pg ml(-1) (RSD, 2.2%) and 2.08 +/- 0.05 pg ml(-1) (RSD, 2.4%), respectively.

A chitosan resin derivatized with N-methyl-(D)-glucamine (CCTS-NMDG) was synthesized by using a cross-linked chitosan (CCTS) as base material. The N-methyl-D-glucamine (NMDG) moiety was attached to the amino group of CCTS through the arm of chloromethyloxirane. The adsorption behavior of 59 elements on the synthesized resin was systematically examined by using the resin packed in a mini-column, passing water samples through it and measuring the adsorbed elements in eluates by ICP-MS. The CCTS-NMDG resin shows high ability in boron sorption with the capacity of 0.61 mmol ml(-1) (= 2.1 mmol g(-1)). The sorption kinetics of this resin was faster than that of the commercially available resins. Other advantages of the synthesized resin are: (1) quantitative collection of boron at neutral pH regions; (2) complete removal of large amounts of matrices; (3) no loss of efficiency over prolonged usage; (4) effective collection of boron in wide range concentration using a mini column containing 1 ml resin; (5) complete elution of boron with 1 mol 1(-1) nitric acid. The resin was applied to the collection/concentration of boron in water samples. Boron in tap water and river water was found to be in the range of 6-8 mu g 1(-1). The limit of detection (LOD) of boron after pretreatment with CCTS-NMDG resin and measurement by ICP-MS was 0.07 mu g 1(-1) and the limit of quantification (LOQ) was 0. 14 mu g 1(-1) when the volume of each sample and eluent was 10 ml.

The method is based on the reaction of formaldehyde with methyl acetoacetate in the presence of ammonia. The increase in the absorbance of the reaction product was measured at 375 nm. An inexpensive light emitting diode (LED)based UV detector (375 nm) was, for the first time, used. Under the optimized experimental conditions, formaldehyde in an aqueous solution was determined over the concentration range from 0.25 to 20.0 x 10(-6) M with a liner calibration graph; the limit of detection (LOD) of 5 x 10(-8) M (1.5 mu g L-1) was possible. The relative standard deviation of 12 replicate measurements of 5 X 10(-6) M formaldehyde was 1.2%. Maximum sampling throughput was about 21 samples/h. The effect of potential interferences such as metals, organic compounds and other aldehyde was also examined. The analytical performance for formaldehyde determination was compared with those obtained by the conventional acetylacetone method, which uses visible absorption spectrophotometry. Finally, the proposed method was successfully applied to the determination of formaldehyde in natural water samples. en-copyright= kn-copyright= en-aut-name=LiQiong en-aut-sei=Li en-aut-mei=Qiong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SritharathikhumPiyanete en-aut-sei=Sritharathikhum en-aut-mei=Piyanete kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=2 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=3 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=4 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University en-keyword=Flow injection kn-keyword=Flow injection en-keyword=Formaldehyde determination kn-keyword=Formaldehyde determination en-keyword=Spectrophotometry kn-keyword=Spectrophotometry en-keyword=Methyl acetoacetate kn-keyword=Methyl acetoacetate en-keyword=UV-light emitting diode (LED) kn-keyword=UV-light emitting diode (LED) END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=5 article-no= start-page=1147 end-page=1150 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=20040611 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Flow injection spectrophotometry coupled with a crushed barium sulfate reactor column for the determination of sulfate ion in water samples en-subtitle= kn-subtitle= en-abstract= kn-abstract=

Catechol-type chitosan resin and salicylic acid-type chitosan resin were easily synthesized for use in estimating the adsorption behavior of 34 elements at pH 1 - 7 in aquatic media. The catechol-type chitosan resin could adsorb Cu(II) at pH 3 - 7, In(III) at pH 4 - 6, Pb(II) and lanthanoids at pH 5 - 7, and U(VI) at pH 4 - 7 more effectively than the salicylic acid-type chitosan resin and the cross-linked chitosan resin (base material). Adsorption ability was in the order: catechol-type chitosan resin > salicylic acid-type chitosan resin > cross-linked chitosan resin.

Ultrapurified water was evaporated to concentrate phosphorus and the final sample volume for analysis was 10 ml. In 0.55 mol 1(-1) HCl, orthophosphate forms molybdophosphate, and then the molybdophosphate forms ion associate with Malachite Green (MG), which can be collected on a tiny membrane filter (diameter: 5 mm, and effective filtering diameter: 2 mm). After the ion associate on the membrane filter is dissolved together with the membrane filter in I ml of methyl cellosolve (MC), the absorbance of MC solution is measured at 627 nm by a flow injection-spectrophotometric detection technique. When 10 ml of the sample solution was used for the procedures and absorbance measurement, the calibration graph is linear up to about 500 ng 1(-1) of phosphorus and the detection limit was 8 ng 1(-1) (S/N = 3). For the determination of phosphorus in an ultrapurified water, 10-40 ml of sample solutions were transferred into poly(tetrafluoroethylene) (PTFE) beaker and evaporated to 5 ml or to dryness. To them, 0.003 mol 1(-1) HCl was added to get 10 ml of final solution, which was used as sample. Phosphate is determined by comparing the slope of the varied sample volume after evaporation/concentration with a slope of the standard calibration graph (a slope comparison method: SCM). The SCM enables to evaluate the concentration of phosphate in ultrapurified waters more sensitively and accurately. en-copyright= kn-copyright= en-aut-name=SabarudinAkhmad en-aut-sei=Sabarudin en-aut-mei=Akhmad kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=2 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University affil-num=3 en-affil= kn-affil=Department of Chemistry, Faculty of Science, Okayama University en-keyword=ultrapurified water kn-keyword=ultrapurified water en-keyword=evaporation/concentration kn-keyword=evaporation/concentration en-keyword=ion associate kn-keyword=ion associate en-keyword=molybdophosphate kn-keyword=molybdophosphate en-keyword=malachite green kn-keyword=malachite green en-keyword=slope comparison method kn-keyword=slope comparison method END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=1 article-no= start-page=161 end-page=164 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20060224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Speciation of chromium in seawater by ICP-AES with dual mini-columns containing chelating resin en-subtitle= kn-subtitle= en-abstract= kn-abstract=

A method for the preconcentration and speciation of chromium in seawater was developed. On-line preconcentration and determination were carried out by using inductively coupled plasma atomic emission spectrometry (ICP-AES) with dual mini-columns containing a chelating resin. In this system, Cr(III) was collected on the first column. The effluent containing residual chromium from the first column was collected on the second column after passing through a reduction-switching unit, in which the reducing agent was introduced, or not, for the reduction of Cr(VI) to Cr(Ill). Cr(VI) was determined as the difference between the concentration of pre-reduced Cr(VI) and Cr(III) in the effluent from the first column. The detection limits for Cr(III) and Cr(VI) were 0.04 and 0.09 mu g l(-1), respectively.

Chitosan resin functionalized with 3,4-dihydroxy benzoic acid (CCTS-DHBA resin) was used as a packing material for flow injection (FI) on-line mini-column preconcentration in combination with inductively coupled plasma-atomic emission spectrometry (ICP-AES) for the determination of trace elements such as silver, bismuth, copper, gallium, indium, molybdenum, nickel, uranium, and vanadium in environmental waters. A 5-mL aliquot of sample (pH 5.5) was introduced to the minicolumn for the adsorption/preconcentration of the metal ions, and the collected analytes on the mini-column were eluted with 2 M HNO3, and the eluates was subsequently transported via direct injection to the nebulizer of ICP-AES for quantification. The parameters affecting on the sensitivity, such as sample pH, sample flow rate, eluent concentration, and eluent flow rate, were carefully examined. Alkali and alkaline earth metal ions commonly existing in river water and seawater did not affect the analysis of metals. Under the optimum conditions, the method allowed the determination of metal ions with detection limits of 0.08 ng mL(-1) (Ag), 0.9 ng mL(-1) (Bi), 0.07 ng mL(-1) (Cu), 0.9 ng mL(-1) (Ga), 0.9 ng mL(-1) (In), 0.08 ng mL(-1) (Mo), 0.09 ng mL(-1) (Ni), 0.9 ng mL(-1) (U), and 0.08 ng mL(-1) (V). By using 5 mL of sample solution, the enrichment factor and collection efficiency were 8-12 fold and 96-102%, respectively, whereas the sample throughput was 7 samples/hour. The method was validated by determining metal ions in certified reference material of river water (SLRS-4) and nearshore seawater (CASS-4), and its applicability was further demonstrated to river water and seawater samples.

In this study, the use of a polymer coated silica capillary and an anionic organic photometric reagent realized a stable baseline and short analytical time. Nine kinds of anions, Cl(-), Br(-), NO(3)(-), SO(4)(2-), C(2)O(4)(2-), ClO(4)(-), F(-), HPO(4)(2-), and HCO(3)(-), were well separated and detected within 12 minutes. Calibration graphs for the anions showed a good linearity in the range of 0 to 4x10(-4) mol dm(-3). Detection limits of the anions were 2x10(-6) mol dm(-3) (HPO(4)(2-)) to 4x10(-5) mol dm(-3) (NO(2)(-)). Anions in river water (Zasu river) and waste water (Okayama University, North district) were measured over 5 days. The waste water contained various kinds of anions, at high concentrations with its large variation, when compared with the river water. The proposed method offers a simple, rapid, and accurate analysis of anions in water samples. en-copyright= kn-copyright= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name=高柳俊夫 kn-aut-sei=高柳 kn-aut-mei=俊夫 aut-affil-num=1 ORCID= en-aut-name=WadaEiko en-aut-sei=Wada en-aut-mei=Eiko kn-aut-name=和田栄子 kn-aut-sei=和田 kn-aut-mei=栄子 aut-affil-num=2 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部化学科 affil-num=2 en-affil= kn-affil=岡山大学理学部化学科 affil-num=3 en-affil= kn-affil=岡山大学理学部化学科 affil-num=4 en-affil= kn-affil=岡山大学理学部化学科 END start-ver=1.4 cd-journal=joma no-vol=21 cd-vols= no-issue= article-no= start-page=4 end-page=10 dt-received= dt-revised= dt-accepted= dt-pub-year=1999 dt-pub=199908 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Determination of trace metals in environmental water samples by inductively coupled plasma - mass spectrometry (ICP-MS) kn-title=誘導結合プラズマ―質量分析法による環境水中の微量金属の定量 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Trace metals in water samples, such as tap water, river water, and sea water, were determined by inductively coupled plasma-mass spectrometry (ICP-MS). ICP-MS has sufficient sensitivity to detect even below the concentrations of ppt level, and therefore the samples were not pretreated with a concentration column. Practical samples were diluted by lo-fold with ultrapure water and measured directly by ICP-MS. The measuring time of one sample was 2.5 min, and the data for 30 elements were obtained simultaneously. The concentrations of heavy metals, such as Cr, Mn, Co, Ni, Cu, Zn, As, Cd, Sb, and Pb, in the water samples were in the ranges of 0.05~82ng/ml. Zasu river and Sibukawa (sea water) contained various kinds of metals, and the concentration ranges were spread in a wide range; for example, Mg was 25700 ppb and In was 2 ppt. ICP-MS is found to be a useful and a powerful instrument for trace amounts of elements, and can be applied satisfactorily to the environmental water analysis. en-copyright= kn-copyright= en-aut-name=LeeKyue-Hyung en-aut-sei=Lee en-aut-mei=Kyue-Hyung kn-aut-name=李啓熒 kn-aut-sei=李 kn-aut-mei=啓熒 aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name=高柳俊夫 kn-aut-sei=高柳 kn-aut-mei=俊夫 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部化学科 affil-num=2 en-affil= kn-affil=岡山大学理学部化学科 affil-num=3 en-affil= kn-affil=岡山大学理学部化学科 affil-num=4 en-affil= kn-affil=岡山大学理学部化学科 END start-ver=1.4 cd-journal=joma no-vol=25 cd-vols= no-issue= article-no= start-page=37 end-page=42 dt-received= dt-revised= dt-accepted= dt-pub-year=2003 dt-pub=200308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=岡山大学周辺の割川水の長期定量データの解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=HamasakiKayoko en-aut-sei=Hamasaki en-aut-mei=Kayoko kn-aut-name=濵崎佳代子 kn-aut-sei=濵崎 kn-aut-mei=佳代子 aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部 affil-num=2 en-affil= kn-affil=岡山大学理学部 END start-ver=1.4 cd-journal=joma no-vol=3 cd-vols= no-issue=3 article-no= start-page=265 end-page=269 dt-received= dt-revised= dt-accepted= dt-pub-year=1987 dt-pub=19870610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spectrophotometric Determination of Anionic Surfactants in River Water with Cationic AZO Dye by Solvent Extraction- Flow Injection Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anionic surfactants in water were determined by a spectrophotometric flow injection technique coupled with solvent extraction. The ion associate which formed between an anionic surfactant and an cationic azo dye was extracted into an organic solvent and the absorbance was measured. The carrier was distilled water, and the reagent solution contained an cationic azo dye and sodium sulfate, the pH of which being adjusted to 5 with acetate buffer. A phase separator with a poly(tetrafluoroethylene) porous membrane (0.8μm pore size) was used to separate the organic phase. Six derivatives of cationic azo dyes and several extracting solvents were examined; a pair of 1-methyl-4-(4-diethylaminophenylazo)- pyridinium cation and chloroform turned out best. The sampling rate was 30 samples per hour. Calibration graphs were linear up to 2×10(-6)M or 3×10(-5)M of anionic surfactant when injection volume was 300 or 100μl, respectively. The relative standard deviation(n=10) was 1.5% for 300μl of 1×10(-6)M sodium dodecylsulfate. The detection limit was as little as 1×10(-8)M of anionic surfactant.

The gas diffusion unit, which was constructed without any glue, could be assembled easily by fastening the screws to tee connectors with ferrules. The new gas-diffusion unit was improved to decrease the dead volume. The unit gave sharper peaks than the previous one, and peaks higher by 10% in the case of CO(2) determination. The gas-diffusion part consisted of an inner microporous polytetrafluoroethylene (PTFE) tube (GORE-TEX®, 1.0 mm i.d., 1.8 mm o.d., pore size 2.0 μm, porosity 50%) and an outer PTFE tube (2.0 mm i.d., 3.0 mm o.d.). Sample solution was injected into the carrier solution (CS), in which the analyte was converted to a gaseous substance which passed through the microporous PTFE membrane to be mixed with the reagent solution (RS) flowing in the space between the outer and the inner tubings. The resulting pH shift caused the color of the indicator in RS to change. The conditions for the determination of total carbonate are as folows; CS was 1.8X×10(-3) mol dm(-3) H(2)SO(4), RS contained Cresol Red (at pH 9.0) and the detection wavelength was 410 nm. The detection limit was 0.96 mg dm(-3) CO(2) (S/N=3), the response was linear up to 172 mg dm(-3), and the sampling rate was 20 h(-1). For ammoniacal nitrogen, CS was 10(-2) mol dm(-3) NaOH, RS contained Cresol Red (pH 7.0) and absorbance was measured at 550 nm. The detection limit was 30μg dm(-3)NH(4)(+)-N (S/N=3), the response was linear up to 3.5 mg dm(-3), and the sampling rate was 30 h(-1). Total carbonate and ammoniacal nitrogen in river and seawater samples were determined satisfactorily. kn-abstract=今回新たに多孔質PTFE(polytetrafluoroethylene)チューブを分離膜とするガス透過装置を試作し,その性能について総炭酸定量用FIA装置を用いて検討した.新しいガス透過装置は組み立てが簡単で,前回製作のものに比べ,約10%の感度向上が達成され,更にピークのテイリングも減少した.本装置を組み込んだFIAにより環境水中の総炭酸,アンモニア態窒素の定量が可能である.いずれの場合もpH変化に伴うクレゾールレッドの呈色変化を測定に利用した.本法によれば多孔質ガス透過チューブ長8cmのとき,172mg dm(-3)(4×10(-3)mol dm(-3))以下の総炭酸を1時間当たり20試料,3.6mg dm(-3)(2.6×10(-4)mol dm(-3))以下のアンモニア態窒素を1時間当たり30試料の速さで測定できた.この際の検出限界(S/N=3に相当)は総炭酸の場合,0.96mg dm(-3)(2×10(-5)mol dm(-3)),アンモニア態窒素の場合は30μg dm(-3)(2×10(-6)mol dm(-3))であった. en-copyright= kn-copyright= en-aut-name=SanadaMasahiro en-aut-sei=Sanada en-aut-mei=Masahiro kn-aut-name=真田昌宏 kn-aut-sei=真田 kn-aut-mei=昌宏 aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=FIA with gas-diffusion unit kn-keyword=FIA with gas-diffusion unit en-keyword=tubular microporous polytetrafluoroethylene kn-keyword=tubular microporous polytetrafluoroethylene en-keyword=determination of total carbonate and ammoniacal nitrogen kn-keyword=determination of total carbonate and ammoniacal nitrogen END start-ver=1.4 cd-journal=joma no-vol=42 cd-vols= no-issue=3 article-no= start-page=151 end-page=157 dt-received= dt-revised= dt-accepted= dt-pub-year=1993 dt-pub=19930305 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Determination of phosphate and arsenate by a flotation-pairing ion exchange/extraction method kn-title=フローテーション/対イオン交換抽出法による極微量リン酸及びヒ酸の吸光光度定量 en-subtitle= kn-subtitle= en-abstract=Flotation-pairing ion exchange-extraction and spectrophotometric determination of trace amounts of phosphate and arsenate were examined. Ion association complexes of heteropoly acids and a bulky cationic dye floated on the interface between an aqueous and a less polor organic solvent phase. After the flotation, the heteropoly acids were exchanged for an anionic dye, which have a high molar absorptivity and the similar maximum absorption wavelength to the cationic dye. The sum of the absorbances of the cationic and the anionic dyes was measured. In this work, malachite green (MG(+)) and 4'-hydroxy-3,5,3',5',2",6"-hexachlorofuchsone (Cl(6)BZ), a hexachloro derivative of benzaurin, were used as a cationic and an anionic dye. The recommended procedure for phosphate determination is as follows. To a 50-cm(3) separatory funnel, take sample solution (up to 10 cm(3)); if arsenate coexists, add 0.1 cm3 of 2×10(-2) M Na(2)S(2)O(3) to reduce arsenate to arsenite. Then, add 1 cm(3) of 10 M hydrochloric acid, 1 cm(3) of 0.4 M (as Mo) molybdate, 0.5 cm(3) of 5×10(-4) M Malachite Green, and 2 cm(3) of flotation solvent (Isobutyl methyl ketone + cyclohexane= 1 +8 v/v). After shaking for 5 min, discard the aqueous phase, and wash the organic phase 2 times with 5 cm(3) of water. After 1 cm(3) of 2×10(-4) M anionic dye solution, 8 cm(3) of 1, 2-dichloroethane and 5 cm(3) of borax buffer (pH 9) are added, shake 10 times by hands. After the phase separation, measure the absorbance of the organic phase at 620 nm. As arsenate reacts under the same conditions as phosphate, arsenate can be determined by subtracting the amounts of phosphate from the total amounts of phosphate and arsenate which were obtained in the absence of Na(2)S(2)O(3). The apparent molar absorptivity of phosphate or arsenate was 5.7×10(5) dm(3) mol(-1) cm(-1), and the absorbance of the reagent blank was 0.005. Six times concentration was achieved when 30 cm(3) of aqueous phase and 5 cm(3) of extraction solvent were used. Bulky anionic ions, such as iodide, perchlorate and lauryl sulfate, did not interfere with the determination of phosphate and arsenate. This method was applied to the determination of phosphate in seawater and iron and steel samples. kn-abstract=フローテーション/対イオン交換抽出法を用いる極微量リン酸,及びヒ酸の吸光光度定量法を確立した.オルトリン酸とモリブデン酸との反応により生成したモリブドリン酸にマラカイトグリーン(MG(+))をイオン会合させ,この会合体を水相と有機相(シクロヘキサン+イソブチルメチルケトン=8+1v/v)の界面にフローテーションさせる.この後,MG(+)と近い極大吸収波長をもつ染料陰イオン(A(-)と略記)とモリブドリン酸を交換し,(MG(+)・A(-))イオン会合体を有機相(フローテーション溶媒+1,2-ジクロロエタン)に抽出する.ヒ酸も類似のイオン会合体を形成するため,同様にして定量することができる.A-としては新規合成酸性染料の4'-ヒドロキシ-3,5,3',5',2",6"-ヘキサクロロフクソン(以後,Cl(6)BZと略記)を用いた.リンを基準とした見掛けのモル吸光係数は620nmで5.7×10(5)dm(3)mol(-1)cm(-1)であった.この方法によるRSDは1×10(-6)Mのリン酸で0.29%(n=10)であった.本法は試薬から試験値が0.005と低く,6倍の濃縮も可能であり,これによりsub-ppb(10(-10)gml(-1))レベルのリンの定量が可能となった.又ヨウ化物イオン,過塩素酸イオン,ラウリル硫酸イオンなどのイオン会合抽出されやすい疎水性イオンの影響は,溶媒抽出法に比べはるかに小さいことが分かった.本法を海水,鉄鋼試料中のリン,ヒ素の定量に応用した. en-copyright= kn-copyright= en-aut-name=GotoNobutake en-aut-sei=Goto en-aut-mei=Nobutake kn-aut-name=後藤伸武 kn-aut-sei=後藤 kn-aut-mei=伸武 aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=flotation-pairing ion-exchange-extraction kn-keyword=flotation-pairing ion-exchange-extraction en-keyword=heteropoly acid kn-keyword=heteropoly acid en-keyword=determination of phosphate and arsenate kn-keyword=determination of phosphate and arsenate en-keyword=Malachite Green and 4'-hydroxy-3,5,3',5',2 kn-keyword=Malachite Green and 4'-hydroxy-3,5,3',5',2 en-keyword=spectrophotometry kn-keyword=spectrophotometry END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=8 article-no= start-page=621 end-page=628 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=19940805 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Separation and determination of metal ions with 2-nitroso-1-naphthol-4-sulfonic acid by high-performance capillary electrophoresiscapillary electrophoresis kn-title=キャピラリー電気泳動法による2-ニトロソ-1-ナフトール4-スルホン酸を用いる金属イオンの分離・定量 en-subtitle= kn-subtitle= en-abstract=Capillary electrophoresis study was carried out by using 2-nitroso-1-naphthol-4-sulfonic acid (nitroso-NW acid) as a chelating and chromogenic agent. Nitroso-NW acid (H2R) reacts with Co(2+) to form the chelate anion, CoR(3)(3-) and also reacts with Fe(2+), Ni(2+), Cu(2+) and Pd(2+). However, except for Ni(2+) and Cu(2+), sharp peaks could not be obtained with a conventional carrier containing HR-and buffer components. This is probably because the metal chelates were highly charged: the chelates of Ni(2+), Cu(2+), Fe(2+), Co(2+) and Pd(2+) are expected to be CuR(2)(2-), Fe(II)R(3)(4-) Co(III)R(3)(3-), NiR(3)(4-) and Pd(OH)(2)(2) R(-), from their electrophoretic mobilities. The peaks of Fe(2+), Co(2+) and Pd(2+) were sharpend by adding a quaternary ammonium ion to the carrier. The quaternary ammonium ion in the carrier acts as a pairing cation of metal chelate anions. Of these, tetrabutylammonium ion(TBA(+)) was the best pairing ion for the metal chelates. By using a carrier containing HR(-), TBA(+) ·Br(-) and buffer components (pH 7), good separation and highly sensitive detection of the five metal ions (Fe(2+), Co(2+), Ni(2+), Cu2+and Pd2+) could be achieved within 7 min. The proposed method was applied to the determination of cobalt in nickel salts. kn-abstract=2-ニトロソ-1-ナフトール-4-スルホン酸(ニトロソ-NW酸)の金属キレート(Fe(2+),Co(2+),Ni(2+),Cu(2+)及びPd(2+))をキャピラリー電気泳動により分離した.通常の泳動液(ニトロソ-NW酸と緩衝剤の混合液)では,Ni(2+),Cu(2+)のみが鋭いピークを与えた.泳動液中に第四級アンモニウムイオンを加えると,ブロードなピークであったFe(2+),Co(2+),Pd(2+)も鋭いピークとなった.泳動液中に添加する第四級アンモニウムイオンの種類と濃度の影響を調べたところ,疎水性のイオンほど,又高濃度ほどキレートの移動度(絶対値)は小さくなることが分かった.これは,第四級アンモニウムイオンがキレート陰イオンと一部イオン会合体を形成し,実質的電荷を下げていることによると考えられる.泳動液組成の最適化を検討した結果,テトラブチルアンモニウムイオンを用いることにより,上述の5種の金属イオンの良好な分離と同時定量が可能となった.本法により,市販ニッケル塩中の微量コバルトの定量を行った. en-copyright= kn-copyright= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=1 ORCID= en-aut-name=KuwabaraMasayosi en-aut-sei=Kuwabara en-aut-mei=Masayosi kn-aut-name=桑原正良 kn-aut-sei=桑原 kn-aut-mei=正良 aut-affil-num=2 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=high-performance capillary electrophoresis kn-keyword=high-performance capillary electrophoresis en-keyword=metal ions kn-keyword=metal ions en-keyword=2-nitroso-1-naphthol-4-sulfonic acid kn-keyword=2-nitroso-1-naphthol-4-sulfonic acid en-keyword=ion-association kn-keyword=ion-association END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue=8 article-no= start-page=513 end-page=517 dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=19980805 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Highly sensitive graphite-furnace AAS of lead using a miniaturemembrane concentration/dissolution method kn-title=微小膜濃縮/黒鉛炉原子吸光法による鉛の高感度定量 en-subtitle= kn-subtitle= en-abstract=極微量の鉛イオンを定量するための濃縮法として,膜濾過捕集系を改良し,微小膜捕集濃縮/溶解法を用い,黒鉛炉AASにより測定する鉛の高感度定量法を開発した.試料溶液に3.5×10(-5)Mゼフィラミンを加えた後,鉛イオンをピロリジンジチオカルバミン酸イオンと錯形成させ,微小メンブランフィルター(MF)を用いて濾過し,膜捕集濃縮する.用いたMFは膜直径5mm,濾過有効径2mm,孔径0.2μmのニトロセルロース製であり,鉛キレートを捕集後,MFをポンチで3mmにカットして用いた.これにより,膜溶解溶媒であるメチルセロソルブの量を100μlまで減少させることができ,高倍率濃縮を達成することができた.試料量10mlの濾過時間は15分であった.試料10mlを用い,メチルセロソルブ200μlに溶解したときの鉛の定量下限は,10 pptであり,鉛40pptを含む試料を用いたときの相対標準偏差は4.51%(n=4)であった.本法により,水道水,河川水中の鉛を定量した. kn-abstract=Ultra-trace amounts of lead were determined by graphite-furnace AAS (GF-AAS) after miniature-membrane filter (MF) concentration/dissolution. Lead was concentrated as a pyrrolidinedithiocarbamate (APDC) chelate on a miniature MF, which was 5mm in diameter, 2mm in effective filtering diameter and 0.2 μm in pore size. After collection of the lead chelate on MF, the MF was cut so as to be 3mm in diameter using a punch. This tiny MF was dissolved in 100 μl of a dissolution solvent (methyl cellosolve), which resulted in a high concentration efficiency. When 10 ml of a sample was used, the concentration ratio was 100. The addition of 5 × 10(-5) M Zephiramine to the sample solution before chelation was effective for collecting lead; the recovery was almost 100%. The filtering time was 15 min for a 10 ml sample solution. The detection limit was 10 ppt when a 10 ml of sample solution was concentrated in 200 μl of methyl cellosolve. Measurements by GF-AAS were carried out using 40 μl of a methyl cellosolve solution. The relative standard deviation for 40 ppt of lead was 4.51% (n= 4). This method was applied to both river- and tap-water samples. en-copyright= kn-copyright= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=1 ORCID= en-aut-name=OhsakiTakashi en-aut-sei=Ohsaki en-aut-mei=Takashi kn-aut-name=大崎隆史 kn-aut-sei=大崎 kn-aut-mei=隆史 aut-affil-num=2 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 en-keyword=lead kn-keyword=lead en-keyword=miniature membrane filter concentration/dissolution kn-keyword=miniature membrane filter concentration/dissolution en-keyword=ammonium pyrrolidinedithiocarbamate kn-keyword=ammonium pyrrolidinedithiocarbamate en-keyword=graphite furnace AAS kn-keyword=graphite furnace AAS END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue=6 article-no= start-page=375 end-page=380 dt-received= dt-revised= dt-accepted= dt-pub-year=1998 dt-pub=19980605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Simultaneous determination of nitrate and nitrite ion by micro-flow injection analysis kn-title=マイクロフローインジェクション分析法による硝酸,亜硝酸イオンの同時定量 en-subtitle= kn-subtitle= en-abstract=試薬,試料量の低減化とオンサイト分析を目的として,マイクロフロー方式FIA(μFIA)による硝酸イオン,亜硝酸イオンの定量について検討した.流路は二流路とし,ダブルプランジャー型マイクロポンプを用い,吐出量は2.5μl stroke-1,流量は50μl min-1とした.吸光検出反応には,スルファニルアミドと2-ナフチルエチレンジアミンを用いるジアゾ化-カップリング反応を用い,538nmで測定した.試料注入量20μlで,内径0.25mm,長さ75 cmの反応コイルを用いれば,通常の河川水程度の硝酸,亜硝酸イオンの定量が可能である.μFIA用のCd/Cu還元ミニカラムは,カドミウムパウダー(60~80メッシュ)を銅コーティングし,内径0.53mmのシリカチューブ(長さ5cm)に詰めて作製した.本ミニカラムによる硝酸イオンの亜硝酸イオンへの還元効率は99%以上であった.スプリット方式により,硝酸亜硝酸イオンの同時定量用流路を構築した.実際試料のオンサイト分析装置には,発光ダイオード(LED)を川いて,消費電力の低減化を計った.硝酸,亜硝酸イオンを単独に定量する場合の検出限界はそれぞれ約2×10(-8)Mであり,同時定量の場合には約10(-7)Mであった.河川水中の硝酸,亜硝酸イオンの同時定量にも応用できることが分かった. kn-abstract=To minimize the sample size, reagent consumption and waste, a micro-flow injection analysis (μFIA) was investigated and applied to the simultaneous determination of nitrate and nitrite ion in water samples. A double-plunger micropump was used to propel a carrier and a chromogenic solution; each flow rate was 50 μl min(-1), and the delivery volume was 2.5 μl per stroke. Nitrate was reduced to nitrite on line by passing through a mini column (0.53 mm i.d.×5 cm) packed with powdered Cd/Cu (6080 mesh). The reduction efficiency was 99% using this reduction column. Detection was carried out at 538 nm with a light-emitting diode used as an azo dye. The carrier solution contained EDTA and NaCl (pH 8.18.4) and the reagent solution contained sulfanilamide, N-(1-naphthyl)ethylenediamine and HCl. For a simultaneous determination, the sample injected into the carrier stream was split into two streams: one passed through the mini Cd/Cu column ; the other passed through a bypass column packed with glass beads. The sample zone passing through the bypass column gave a first peak derived from nitrite; the other sample zone passing through the reduction column gave the second peak derived from nitrate and nitrite. The detection limits of nitrate and nitrite were about 1×10(-7) M using the proposed simultaneous determination system. en-copyright= kn-copyright= en-aut-name=MaLan en-aut-sei=Ma en-aut-mei=Lan kn-aut-name=馬蘭 kn-aut-sei=馬 kn-aut-mei=蘭 aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=3 ORCID= en-aut-name=HattoriTakayasu en-aut-sei=Hattori en-aut-mei=Takayasu kn-aut-name=服部隆康 kn-aut-sei=服部 kn-aut-mei=隆康 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=旭テクネイオン(株) en-keyword=micro-flow injection analysis kn-keyword=micro-flow injection analysis en-keyword=river water, nitrate and nitrite kn-keyword=river water, nitrate and nitrite en-keyword=simultaneous determination kn-keyword=simultaneous determination en-keyword=mini Cd/Cu reduction column kn-keyword=mini Cd/Cu reduction column END start-ver=1.4 cd-journal=joma no-vol=51 cd-vols= no-issue=9 article-no= start-page=785 end-page=789 dt-received= dt-revised= dt-accepted= dt-pub-year=2002 dt-pub=20020905 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Highly sensitive determination of copper ion with newly synthesized water-soluble fluorescent reagents having a 1,8-diaminonaphthalene-3,6-disulfonic acid skeleton kn-title=1,8-ジアミノナフタレン-3,6-ジスルホン酸骨格を持つ新規水溶性蛍光試薬の合成と銅イオンの高感度定量への応用 en-subtitle= kn-subtitle= en-abstract=水溶性蛍光試薬として1,8-ジヒドロキシナフタレン-3,6-ジスルホン酸 (クロモトロープ酸) に類似した1,8-ジアミノナフタレン-3,6-ジスルホン酸骨格を持つ1,8-ジ-(トルエン-4-スルホニルアミノ)-ナフタレン-3,6-ジスルホン酸 (BTND) 及び1,8-ジ-(トリフルオロメタンスルホニルアミノ)-ナフタレン-3,6-ジスルホン酸 (BTFND) を合成し, 金属イオンとの反応性を検討した.

BTND was selective to Cu(2+), and the fluorescence was quenched quantitatively at pH 7 in an aqueous solution (λ(ex)=360 nm and λ(em)=405 nm). The calibration graph for Cu(2+) with BTND was rectilinear over the concentration range from 0 to 10(-5) M and the detection limit was 2.0×10(-7) M.

At pH 7, Nitro-PAPS reacts with various metal ions to form chelate compounds having large molar absorptivities. Although chelate formation is useful for the highly sensitive detection of metal ions, the resolution of the metal complexes is poor at pH 7. Cetyltrimethylammonium bromide was added to suppress any electroosmotic flow. The hydration of nitro groups of a chelating agent and chelates was controlled by the addition of urea. Sodium sulfate was also utilized to sharpen the signals of metal chelates by a field-enhanced stacking effect. As a result, the resolution was improved and the determination of 10-7 M level metal ions was possible. The proposed method was applied to the analysis of metal impurity at ultratrace levels in commercially available nickel and iron salts. en-copyright= kn-copyright= en-aut-name=KagawaTakuji en-aut-sei=Kagawa en-aut-mei=Takuji kn-aut-name=香川拓司 kn-aut-sei=香川 kn-aut-mei=拓司 aut-affil-num=1 ORCID= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name=高柳俊夫 kn-aut-sei=高柳 kn-aut-mei=俊夫 aut-affil-num=2 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 en-keyword=capillary zone electrophoresis kn-keyword=capillary zone electrophoresis en-keyword=metal ions kn-keyword=metal ions en-keyword=2-(5-nitro-2-pyridylazo)-5-(N-propyl-N-sulfopropylamino)phenol kn-keyword=2-(5-nitro-2-pyridylazo)-5-(N-propyl-N-sulfopropylamino)phenol en-keyword=nickel and iron salt kn-keyword=nickel and iron salt en-keyword=impurity analysis kn-keyword=impurity analysis END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue= article-no= start-page=20 end-page=25 dt-received= dt-revised= dt-accepted= dt-pub-year=1952 dt-pub=195208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=MEDICAL STUDIES ON CHONDROITIN SULFATE (2nd Report) kn-title=コンドロイチン硫酸の医学的研究-2- en-subtitle= kn-subtitle= en-abstract= kn-abstract=After the internal use of daily 3 grams of crude chondroitin sulfate cholinesterase activity of serum decreased and elimination of glycuronic acid in urine increased, but no definite change in serum mucoprotein level was observed.

It was accelerated by making a burn to the skin of the bathed animals. Layton and Dziewiatkowski proved that the parenterally administered sulfate ion was partly fixed in the connective tissue as chondroitin sulfate. The author had proved that chondroitin sulfate relieves pain, increases peripheral circulation and when administered parenterally promotes production of immune bodies. In Japan natural and artificial Glauber's salt spring bath are known to have a beneficial effect on wound healing, but no satisfactory explanation was given till today.

Consequently, the total of reported acatalasemic cases amounted to 80 cases of 37 families by the end of 1964. en-copyright= kn-copyright= en-aut-name=TakaharaShigeo en-aut-sei=Takahara en-aut-mei=Shigeo kn-aut-name=高原滋夫 kn-aut-sei=高原 kn-aut-mei=滋夫 aut-affil-num=1 ORCID= en-aut-name=OguraYoshio en-aut-sei=Ogura en-aut-mei=Yoshio kn-aut-name=小倉義郎 kn-aut-sei=小倉 kn-aut-mei=義郎 aut-affil-num=2 ORCID= en-aut-name=OkazakiHideo en-aut-sei=Okazaki en-aut-mei=Hideo kn-aut-name=岡崎英生 kn-aut-sei=岡崎 kn-aut-mei=英生 aut-affil-num=3 ORCID= en-aut-name=YasuharaKozo en-aut-sei=Yasuhara en-aut-mei=Kozo kn-aut-name=安原晧三 kn-aut-sei=安原 kn-aut-mei=晧三 aut-affil-num=4 ORCID= en-aut-name=SadamotoMasanori en-aut-sei=Sadamoto en-aut-mei=Masanori kn-aut-name=貞本昌規 kn-aut-sei=貞本 kn-aut-mei=昌規 aut-affil-num=5 ORCID= en-aut-name=OhshimaAkio en-aut-sei=Ohshima en-aut-mei=Akio kn-aut-name=大島昭夫 kn-aut-sei=大島 kn-aut-mei=昭夫 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=2 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=3 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=4 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=5 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=6 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 END start-ver=1.4 cd-journal=joma no-vol=80 cd-vols= no-issue=1-2 article-no= start-page=65 end-page=75 dt-received= dt-revised= dt-accepted= dt-pub-year=1968 dt-pub=19680228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Lactic Dehydrogenase Activity and Isozyme in Malignant Disease Part 2 Effects of Chemotherapy on Serum Lactic Dehydrogenase Activity and Isozyme of Tumor-Bearing Mice kn-title=悪性腫瘍における乳酸脱水素酵素とそのIsozymeに関する研究 第二編 担腫瘍マウス血清乳酸脱水素酵素活性及びそのIsozyme patternに及ぼす抗癌剤の影響について en-subtitle= kn-subtitle= en-abstract= kn-abstract=Alterations of serum lactic dehydrogenase (S-LDH) activity and isozyme during therapy in tumor-bearing mice were assayed. 1. Normal Strong A mice receiving Mitomycin C (MMC), Chromomycin A(3) (TM), and Chloroquine phosphate (CQ) respectively were evaluated for S-LDH activity. S-LDH activities of the mice receiving MMC and TM were about twice as high as mormal, this seems to be the side effects of chemotherapeutic agents. The strong A mice receiving CQ showed no changes in S-LDH activity. 2. The strong A mice bearing Bashford carcinoma and the Swiss mice bearing fibrosarcoma were evaluated at weekly intervals for SLDH activity and isozymes. S-LDH activities gradually elevated for 4 weeks. In the Strong A mice bearing Bashford carcinoma LD(3) in creased and LD(1) decreased gradually. In the Swiss mice bearing fibrosarcoma LD(3) was higher than normal at every week. 3. S LDH activities in tumor-bearing mice undergoring therapy with MMC and TM, especially MMC, markedly decreased correlating with tumor regression. As to the S-LDH isozyme, LD(3) in mice receiving TM decreased correlating with decrease of S-LDH activity. In mice receiving others no characteristics were observed. 4. In couclusion, the assay of S-LDH activity and isozymes during therapy directing at tumors are useful in determining wheather or not a chemotherapentic agent affects the tumors. en-copyright= kn-copyright= en-aut-name=OshimaYukiko en-aut-sei=Oshima en-aut-mei=Yukiko kn-aut-name=大島由紀子 kn-aut-sei=大島 kn-aut-mei=由紀子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部平木内科教室 END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=5-6 article-no= start-page=453 end-page=463 dt-received= dt-revised= dt-accepted= dt-pub-year=1967 dt-pub=19670630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on Lactic Dehydrogenase Activity and Isozyme in Malignant Disease Part I.

Serum lactic dehydrogenase (S-LDH) activity and isozyme were measured in 29 patients with leukemia. The elevated S-LDH levels were demonstrated in all cases of acute leukemias and chronic myelocytic leukemias and in a half of cases of chronic lymphocytic leukemias. The S-LDH isozyme can be identified five fractions by means of agar gel electrophoresis. The changes of pattern of S-LDH isozyme were observed in all types of leukemia. It was the increased third (LD(3)), second (LD(2)) and first (LD(1)) fractions of LDH isozyme and the decreased fifth fraction (LD(5)). The most significant fraction in leukemia was LD(3), and the increased LD(3) and decreased LD(5) were observed in 25 of 29 cases (86 % ). 2. The degree of S-LDH elevation appeared to be the greatest in the acute lymphatic and the smallest in the chronic lymphatic leukemia. The degree of increase of LD(3) was independent on the type of leukemia. 3. As to the correlation of S-LDH with clinical findings, the level of S-LDH and LD(3) well correlated with the percentage of circulating immature leukocytes, but not with the absolute number of leukocyte. 4. The serial S-LDH levels and LD(3) closely paralleled with the clinical courses in 10 cases of 29 patients with leukemia and relatively well paralleled in 13 cases. 5. In regard to possible mechanisms of S-LDH elevation in leukemia, acceleration of biosynthesis of LDH in the leukemic cells and liberation of the enzyme from the cells might be suggested. en-copyright= kn-copyright= en-aut-name=OshimaYukiko en-aut-sei=Oshima en-aut-mei=Yukiko kn-aut-name=大島由紀子 kn-aut-sei=大島 kn-aut-mei=由紀子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部平木内科教室 END start-ver=1.4 cd-journal=joma no-vol=83 cd-vols= no-issue=7-8 article-no= start-page=259 end-page=265 dt-received= dt-revised= dt-accepted= dt-pub-year=1971 dt-pub=19710830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=昭和43年度および44年度Acatalasemia, Hypocatalasemia調査集計 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=高原滋夫 kn-aut-sei=高原 kn-aut-mei=滋夫 aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=小倉義郎 kn-aut-sei=小倉 kn-aut-mei=義郎 aut-affil-num=2 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=小野田元男 kn-aut-sei=小野田 kn-aut-mei=元男 aut-affil-num=3 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=大島昭夫 kn-aut-sei=大島 kn-aut-mei=昭夫 aut-affil-num=4 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=住田昭三 kn-aut-sei=住田 kn-aut-mei=昭三 aut-affil-num=5 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=滝口峻 kn-aut-sei=滝口 kn-aut-mei=峻 aut-affil-num=6 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=尾関安英 kn-aut-sei=尾関 kn-aut-mei=安英 aut-affil-num=7 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=笠井英夫 kn-aut-sei=笠井 kn-aut-mei=英夫 aut-affil-num=8 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=黒田泰生 kn-aut-sei=黒田 kn-aut-mei=泰生 aut-affil-num=9 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=大倉興司 kn-aut-sei=大倉 kn-aut-mei=興司 aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=2 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=3 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=4 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=5 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=6 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=7 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=8 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=9 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科学教室 affil-num=10 en-affil= kn-affil=東京医科歯科大学人類遺伝研究室 END start-ver=1.4 cd-journal=joma no-vol=93 cd-vols= no-issue=7-8 article-no= start-page=701 end-page=708 dt-received= dt-revised= dt-accepted= dt-pub-year=1981 dt-pub=19810830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Multiple polypoid filling defects of the duodenal bulb kn-title=十二指腸球部多発陰影欠損について en-subtitle= kn-subtitle= en-abstract= kn-abstract=Multiple polypoid filling defects of the duodenal bulb are infrequently encountered. Two cases of multiple filling defects of the duodenal bulb are reported in this paper. Case 1. A 42 year old female complained of abdominal fullness and epigastralgia. On examination, generalized peripheral lymphadenopathy and marked hepatosplenomegaly were noted. Cervical lymphnode biopsy revealed a diffuse, poorly-differanciated lymphocytic lymphoma. X-ray examination of the gastrointestinal tract showed multiple filling defects localized at the duodenal bulb. Endoscopy disclosed multiple well-defined protrusions with small mucosal ulceration over the the whole circumference of the duodenal wall. Case 2. A 36 year old female had no subjective symptoms. At gastric mass screening, numerous polypoid elevations of the duodenal bulb were pointed out. Detailed gastrointestinal x-ray examination showed numerous, tiny, round polypoid nodules localized at the duodenal bulb. These nodules were 2-3mm in size with no mucosal ulceration. The endoscopic biopsy specimen revealed lymphoid hyperplasia of the duodenal bulb. en-copyright= kn-copyright= en-aut-name=MorinoYasuo en-aut-sei=Morino en-aut-mei=Yasuo kn-aut-name=森野靖雄 kn-aut-sei=森野 kn-aut-mei=靖雄 aut-affil-num=1 ORCID= en-aut-name=TakedaYoshihiro en-aut-sei=Takeda en-aut-mei=Yoshihiro kn-aut-name=竹田芳弘 kn-aut-sei=竹田 kn-aut-mei=芳弘 aut-affil-num=2 ORCID= en-aut-name=MorimotoSetsuo en-aut-sei=Morimoto en-aut-mei=Setsuo kn-aut-name=森本節夫 kn-aut-sei=森本 kn-aut-mei=節夫 aut-affil-num=3 ORCID= en-aut-name=MiyakeMasayoshi en-aut-sei=Miyake en-aut-mei=Masayoshi kn-aut-name=三宅正淑 kn-aut-sei=三宅 kn-aut-mei=正淑 aut-affil-num=4 ORCID= en-aut-name=HayashiHidehiro en-aut-sei=Hayashi en-aut-mei=Hidehiro kn-aut-name=林英博 kn-aut-sei=林 kn-aut-mei=英博 aut-affil-num=5 ORCID= en-aut-name=EzoeHiroshi en-aut-sei=Ezoe en-aut-mei=Hiroshi kn-aut-name=江添弘 kn-aut-sei=江添 kn-aut-mei=弘 aut-affil-num=6 ORCID= en-aut-name=KimotoShin en-aut-sei=Kimoto en-aut-mei=Shin kn-aut-name=木本真 kn-aut-sei=木本 kn-aut-mei=真 aut-affil-num=7 ORCID= en-aut-name=JojaIkuo en-aut-sei=Joja en-aut-mei=Ikuo kn-aut-name=上者郁夫 kn-aut-sei=上者 kn-aut-mei=郁夫 aut-affil-num=8 ORCID= en-aut-name=HashimotoKeiji en-aut-sei=Hashimoto en-aut-mei=Keiji kn-aut-name=橋本啓二 kn-aut-sei=橋本 kn-aut-mei=啓二 aut-affil-num=9 ORCID= en-aut-name=AonoKaname en-aut-sei=Aono en-aut-mei=Kaname kn-aut-name=青野要 kn-aut-sei=青野 kn-aut-mei=要 aut-affil-num=10 ORCID= en-aut-name=HayashiKyoichi en-aut-sei=Hayashi en-aut-mei=Kyoichi kn-aut-name=林恭一 kn-aut-sei=林 kn-aut-mei=恭一 aut-affil-num=11 ORCID= en-aut-name=TakaokaKazuko en-aut-sei=Takaoka en-aut-mei=Kazuko kn-aut-name=高岡和子 kn-aut-sei=高岡 kn-aut-mei=和子 aut-affil-num=12 ORCID= en-aut-name=OshimaYukiko en-aut-sei=Oshima en-aut-mei=Yukiko kn-aut-name=大島由起子 kn-aut-sei=大島 kn-aut-mei=由起子 aut-affil-num=13 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=2 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=3 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=4 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=5 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=6 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=7 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=8 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=9 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=10 en-affil= kn-affil=岡山大学医学部放射線医学教室 affil-num=11 en-affil= kn-affil=岡山大学医学部第II内科学教室 affil-num=12 en-affil= kn-affil=岡山大学医学部第II内科学教室 affil-num=13 en-affil= kn-affil=三菱水島病院内科 en-keyword=Duodenal bulb kn-keyword=Duodenal bulb en-keyword=multiple polypoid nodules kn-keyword=multiple polypoid nodules END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20090325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=bFGF局所投与による下顎骨骨質改善効果の検討 ‐神経提由来骨髄細胞と中胚葉由来骨髄細胞の骨芽細胞分化ならびに破骨細胞分化の相違とbFGFへの反応性‐ en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OshimaMasamitsu en-aut-sei=Oshima en-aut-mei=Masamitsu kn-aut-name=大島正充 kn-aut-sei=大島 kn-aut-mei=正充 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue= article-no= start-page=1 end-page=7 dt-received= dt-revised= dt-accepted= dt-pub-year=1952 dt-pub=195211 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=STUDIES ON SERUM MUCOPROTEIN (1) SERUM MUCOPROTEIN LEVEL IN NORMAL AND PATHOLOGICAL STATES OF JAPANESE. kn-title=血清Mucoprotein含有量(1)正常人並に各種疾患患者に於ける血清Mucoprotein含有量 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Serum mucoprotein level in 16 normnls and 3CO cases of diseased was investignted by Winzler' s method.

Chondroitin Sulfate promotes the blood clotting time by intravenous injection, but has no influence on blood viscosity. It inhibits the action of cholin esterase slightly in vitro and shows a tendency to increase peripheral circulation by Laewen-Trendelenburgs method. It showed no definite effect on blood pressure in the above-mentioned patients. By Magnus method it was shown that chondroitin sulfate accelerates the motility of the isolated rabbit intestine and suppresses the action of adrenalin. Chondroitin sulfate increases the permeability of tissue, but it shows a slight inhibitory action on testicular byaluronidase. Peroral administration of chondroitin sulfate promotes diuresis, increases the elimination of total sulfate and diminishes the neutral sulfur in the urine. en-copyright= kn-copyright= en-aut-name=OshimaYoshio en-aut-sei=Oshima en-aut-mei=Yoshio kn-aut-name=大島良雄 kn-aut-sei=大島 kn-aut-mei=良雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所内科 END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue= article-no= start-page=49 end-page=51 dt-received= dt-revised= dt-accepted= dt-pub-year=1952 dt-pub=195203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=SENSITIVITY TO HISTAMINE DURING A SERIES OF THERMAL BATHS. kn-title=温泉浴による変調の研究, ヒスタミン感受性の変化 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sensitivity of mice to histamine was estimated with the death-rate by its subcutaneous injection. In control group without bath ten mg. of histamine per ten g. of body weight proved to be tolerable, but twenty mg. of histamine per ten g. of body weight was lethal in August. To 24 mice were given everyday a plain water bath at 37℃ for ten minutes. To another 24 mice were given everyday a thermal bath of Misasa at 37℃for ten minutes. On the 4th, 7th, 14th and 21st day to each six mice of both groups was given a subcutaneous injection of histamine, namely to three mice was given ten mg. of histamine per ten g. of bodyweight and to another three mice was given twenty mg. of histamine per ten g. of body weight. In plain water bath group no change in death rate was shown during the series of bath days. But in the thermal bath group a 100% 1ethality was recognized on the 4th day, 67% lethality was proved on the 7th day and only 17% lethality was shown on the 14th day. Histamine or histaminelike substance is known to be a chemical agent liberated in the skin by any skin irritants. And the above-mentioned change in the sensitivity to histamine during a series of thermal baths suggests an explanation to the mechanism of thermal crisis that has a tendency to occur in the first week of thermal bath cure. en-copyright= kn-copyright= en-aut-name=OshimaYoshio en-aut-sei=Oshima en-aut-mei=Yoshio kn-aut-name=大島良雄 kn-aut-sei=大島 kn-aut-mei=良雄 aut-affil-num=1 ORCID= en-aut-name=YokotaTakeo en-aut-sei=Yokota en-aut-mei=Takeo kn-aut-name=横田剛男 kn-aut-sei=横田 kn-aut-mei=剛男 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学温泉研究所内科 affil-num=2 en-affil= kn-affil=岡山大学温泉研究所内科 END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue= article-no= start-page=46 end-page=48 dt-received= dt-revised= dt-accepted= dt-pub-year=1952 dt-pub=195203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=SEASONAL DIFFERENCE IN THE EFFECT OF THERMAL BATH ON BLOOD CATALASE. kn-title=温泉浴作用の季節による差違: 血液カタラーゼ数にみられた変化 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Blood catalase level in healthy rabbits was measured before and after thermal bath of Misasa in January, May, July and September.

elements in natural water samples were determined simultaneously by air-segmented flow-injection/inductively coupled plasma-mass spectrometry(SFI/ICP-MS).A small volume of the sample solutions(80μl) was introduced into a nebulizer by an air-segmented flow-injection(SFI) system, and a maximum of fifteen elements were measured during each run.A chitosan-based chelating resin containing functional groups of iminodiacetate was used to separate and enrich analyte metal ions.A 50-fold preconcentration using 50ml of sample solutions was achieved by the proposed method, where 1ml of 0.1M nitric acid was added to residues after drying the chelating column effluent.At pH6, several heavy metals(Fe, Ni, Co, Cu, Zn, Ag, Cd, Pb and U) and rare earth elements(REEs) were quantitatively retained on the chelating resin column, whereas alkali and alkaline earth metals were eluted from the column by rinsing with 5ml of a 0.2M ammonium acetate solution.Metals adsorbed on the chelating resin column were recovered by elution with 10ml of 1M nitric acid.The proposed method was applied to the determination of trace elements in several natural water samples, such as river water and mineral drinking water. kn-abstract=本法では,各種天然水中の極微量金属成分を同時定量する目的で空気分節試料導入/ICP-MSシステムを用いて,微少量試料(数十μl)を前処理せずにネブライザーに送り込み,多数の金属成分の定量が可能であった。共存主成分による質量干渉を受ける一部遷移金属や直接試料導入では感度の足りない元素については,イミノ二酢酸型キトサンキレート樹脂充填カラムによる分離·濃縮操作の併用によって更に信頼性の高いデータが得られることが分かった。前処理においては,体積1mlのミニカラムを用いて50mlの溶液試料から50倍濃縮を行い,試料·試薬·廃液すべてを少量化することができた。本ICP-MSシステムでは試料導入量は80μlで十分であり,1mlでも数回繰り返し測定が可能で,しかも多元素同時分析ができた。確立した分析法を用いて河川水や市販のミネラルウォーターに応用し,希土類を含め45種の微量元素の定量が可能となった。

possessing the dithiocarbamate moiety (DTC-chitosan resin) was synthesized using cross-linked chitosan as a base material. The adsorption behavior of trace metal ions on the DTC-chitosan resin was systematically examined by packing it in a mini-column (1 ml of the resin) and measuring the recovery by ICP-MS. The resin could adsorb almost 100% of 7 kinds of metals(Cu, Mo, Ag, Te, W, Hg and Bi) at pH ranges from acidic to neutral. However, elution of these metals from the resin was difficult. In this study, we improved the recovery efficiency by a pretreatment of the resin: the resin was added to 100 ml of a 0.1 M copper sulfate solution, stirred for 24 h and washed sufficiently with 1 M nitric acid and water. With this pretreatment, metals adsorbed on 1 ml of the resin were readily eluted with 1 M nitric acid (10 ml). This method was applied to the determination of metals in river-water samples; the RSDs (10-fold preconcentration) were within 5%. kn-abstract=キレート官能基としてジチオカルバミン酸を架橋キトサンに導入した樹脂を合成した.ジチオカルバミン酸型キトサン樹脂への金属捕集挙動はカラム法を用いて誘導結合プラズマ質量分析法(ICP-MS)により評価した.銅,モリブデン,銀,テルル,タングステン,水銀,ビスマスは幅広いpH範囲で樹脂に捕集された.これらのうち,水溶液中に陽イオンとして存在する銅,銀,テルル,水銀,ビスマスは,キレート生成により樹脂に捕集され,モリブデン,タングステンのように酸素酸として存在する金属は,キレート生成とイオン交換により吸着していると考えられる.この樹脂は通常の溶離酸濃度では金属の溶離が困難であったので,試料処理前に樹脂をあらかじめ0.1 Mの銅イオン溶液とかくはんし,樹脂内部の強い吸着サイトに銅を吸着させておくことで,金属の溶離を改善することに成功した.この前処理をした樹脂1 mlを用いて捕集した金属は,1 M硝酸10 mlでほぼ100%回収可能であった.本法を河川水中の微量金属の定量に応用したところ,相対標準偏差5% 以内で定量可能であった. en-copyright= kn-copyright= en-aut-name=NinomiyaTakahiko en-aut-sei=Ninomiya en-aut-mei=Takahiko kn-aut-name=二宮崇彦 kn-aut-sei=二宮 kn-aut-mei=崇彦 aut-affil-num=1 ORCID= en-aut-name=OshitaKoji en-aut-sei=Oshita en-aut-mei=Koji kn-aut-name=大下浩司 kn-aut-sei=大下 kn-aut-mei=浩司 aut-affil-num=2 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部化学科 affil-num=2 en-affil= kn-affil=岡山大学理学部化学科 affil-num=3 en-affil= kn-affil=岡山大学理学部化学科 affil-num=4 en-affil= kn-affil=岡山大学理学部化学科 en-keyword=chitosan resin kn-keyword=chitosan resin en-keyword=dithiocarbamate kn-keyword=dithiocarbamate en-keyword=heavy metals kn-keyword=heavy metals en-keyword=elution method kn-keyword=elution method en-keyword=preconcentartion kn-keyword=preconcentartion END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=4 article-no= start-page=345 end-page=351 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=2004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Highly sensitive determination of boron with 1,8-dihydroxynaphthalene-3,6-disulfonic acid in ultrapurified water by fluorescence detection/flow-injection analysis kn-title=クロモトロープ酸を用いる高感度蛍光検出/フローインジェクション分析法による超純水中の極微量ホウ素の定量 en-subtitle= kn-subtitle= en-abstract=Boron as boric acid was determined as a complex with chromotropic acid at pH 6.0 in an aqueous medium by fluorescence detection/flow-injection analysis. The complex was detected by measuring the fluorescence intensities (λ(ex) = 313 nm, λ(em) = 360 nm). EDTA was used as a buffer component with the role of a masking agent to metal ions. The background fluorescence of chromotropic acid could be decreased by mixing with 0.1 M ammonia water after complex formation, resulting in a stable baseline. The calibration graph was rectilinear over 10(−9)∼10(−6) mol dm(−3) (M), and the detection limit was 5×10(−10) M (S/N = 3). The reproducibility was 3.61% (n = 10, with the peak height) at 6×10(−9) M of boron and sample throughput was 40 h(−1). Applications to river water, ion-exchanged water and distilled water could be achived without any pretreatments. For the analysis of ultrapurified water, an evaporation/preconcentration procedure was carried out, because the concentration was under the LOD and no reference water which could be used for the carrier solution or preparation of the reagent solutions. kn-abstract=超純水中の極微量ホウ素を定量するために,クロモトロープ酸を用いるホウ素の蛍光検出/フローインジェクション(FIA)法の諸条件を再検討し,検出限界を10分の1の5×10(-10) Mに下げることに成功し,大幅な感度向上を達成した.クロモトロープ酸とホウ酸との反応生成物の蛍光を利用するホウ素のFIA法における残存クロモトロープ酸の蛍光強度を低下させるために,アンモニア水を加え,アルカリ性にした.緩衝液としてエチレンジアミン四酢酸を含む酢酸緩衝液を用い,金属のマスキングを兼ねたpH調整を行うことにより,非常に安定なベースラインを得ることに成功した.流量,反応コイル長,試料注入量,試薬濃度等のFIAパラメーターについて感度向上の観点から最適化を行い,ホウ素錯体の蛍光測定(励起波長λ(ex)=313 nm,蛍光波長λ(em)=360 nm)により,前処理なしでホウ素10(-9) Mの定量が可能となった.S/N=3での検出限界は5×10(-10) M(5 ppt)で,現在最も高感度な定量法である.ホウ素6×10(-9) Mの10回繰り返し実験の相対標準偏差(RSD)は3.6%(n=10)であり,1時間に40試料の分析が可能であった.河川水,蒸留水,イオン交換水などに存在する程度の金属イオン及び陰イオンは定量を妨害しない.本法により,イオン交換水,蒸留水中に存在するホウ素は直接定量できた.超純水中に存在する微量のホウ素(10(-10) Mレベル)は,加熱濃縮操作法を併用することにより,定量可能となった. en-copyright= kn-copyright= en-aut-name=LiZhen Hai en-aut-sei=Li en-aut-mei=Zhen Hai kn-aut-name=李貞海 kn-aut-sei=李 kn-aut-mei=貞海 aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部 affil-num=2 en-affil= kn-affil=岡山大学理学部 affil-num=3 en-affil= kn-affil=岡山大学理学部 en-keyword=boron kn-keyword=boron en-keyword=chromotropic acid kn-keyword=chromotropic acid en-keyword=ultrapurified water kn-keyword=ultrapurified water en-keyword=fluorescence/flow injection analysis kn-keyword=fluorescence/flow injection analysis END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=1 article-no= start-page=1 end-page=6 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=2004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Development of a micro-flow titration method and application to acid-base titration kn-title=微量フロー滴定分析法の開発と酸塩基滴定への応用 en-subtitle= kn-subtitle= en-abstract=A flow titration analysis method based on flow ratiometry was developed in this study from the viewpoint of simplicity, rapidity, automation, and cost efficiency. Sample and titrant solutions react while the solutions are continuously propelled by individual pumps at different flow rates. The flow rates are accurately controlled and changed independently, and the color change of an indicator gives an equivalent point. The concentration of analyte was determined by using the ratio of the flow rate and the equivalent point. The fundamental properties of the flow titration method were evaluated through acid-base titration, and compared with the conventional manual titration. When Phenolphthalein or Cresol Red was used as an indicator added in either the sample solution or the titrant solution, linear calibration graphs were obtained for all titrations examined, including strong and weak acids. The proposed method was applied to the titration of carbonate salt using Bromocresol Green and Phenolphthalein. Two isolated end-points were obtained in one sequential measurement corresponding to carbonate and bicarbonate ions. The proposed titration method was applied to the analysis of commercial vinegar samples. The results agreed well with the ones obtained by the conventional titration method; the relative standard deviations for the end point were within 0.3%. The volume of wastewater per one measurement can be reduced down to about 100 μl by the proposed method, while a practical method requires about 50 ml. kn-abstract=容量分析法の簡便化,迅速化,自動化及び省力化を含む高機能化を目的として,送液ポンプの流量比に基づくフロー滴定システムの構築と応用について検討した.フロー滴定分析法は,連続して流れる試料液,滴定剤溶液の正確な流量制御を基本原理としている.2台の送液ポンプを用いてそれらの流量を変化させながら試料液(被滴定液)と滴定剤(滴定液)を送液し,流れ内において混合・反応させ,指示薬の変色を用いて試料液中の分析対象物質濃度を流量比から定量する容量分析法である.各種酸塩基滴定を通して本法の性能評価を行い,従来法との比較を行った.酸塩基指示薬としてフェノールフタレイン,あるいはクレゾールレッドを試料液又は滴定剤へ添加したところ,強酸,弱酸を問わず検討したすべての系において直線性の高い検量線が得られた.また,終点検出の相対標準偏差は0.3%未満であった.更に,滴定剤に2種類の指示薬を用いる多塩基酸・多酸塩基の連続滴定法について検討した.炭酸塩の分析ではブロモクレゾールグリーンとフェノールフタレインを指示薬として用い,炭酸イオン,重炭酸イオンに由来する二つの当量点を一試料測定で検出できた. 本法を市販されている食酢の分析に適用したところ,従来法により決定した酢酸濃度と良好な一致を得た.1試料測定当たりの廃液量は50 ml程度から100 μl程度まで大幅に低減化することができ,フロー滴定分析法により全操作の自動化,試料・廃液量の大幅な低減化,滴定時間の短縮等の高機能化を達成した. en-copyright= kn-copyright= en-aut-name=KonishiHironobu en-aut-sei=Konishi en-aut-mei=Hironobu kn-aut-name=小西明伸 kn-aut-sei=小西 kn-aut-mei=明伸 aut-affil-num=1 ORCID= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name=高柳俊夫 kn-aut-sei=高柳 kn-aut-mei=俊夫 aut-affil-num=2 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部化学科 affil-num=2 en-affil= kn-affil=岡山大学理学部化学科 affil-num=3 en-affil= kn-affil=岡山大学理学部化学科 affil-num=4 en-affil= kn-affil=岡山大学理学部化学科 en-keyword=flow titration analysis kn-keyword=flow titration analysis en-keyword=flow ratiometry kn-keyword=flow ratiometry en-keyword=acid-base titration kn-keyword=acid-base titration END start-ver=1.4 cd-journal=joma no-vol=103 cd-vols= no-issue=4 article-no= start-page=387 end-page=397 dt-received= dt-revised= dt-accepted= dt-pub-year=1991 dt-pub=1991 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the lymphocyte function bronchial asthma Part 1.

The allergic mechanisms of asthmatic attack induced by these antigens were analyzed to clarify the role of cellular immunity in the pathogenesis of bronchial asthma. Mite and Candida antigens were applied to lymphocyte blastogenesis in asthmatic patients. Both lymphocytes in bronchoalveolar lavage fluid (BALF) and in peripheral blood of asthmatic patients responded significantly to mite and Candida antiten. Furthermore, BALF lymphocytes of patients with non-atopic and intractable asthma showed higher responses against Candida antigen than those of patients with atopic and non-intractable asthma, while peripheral blood lymphocytes showed a higher response against mite antigen in patients with atopic and non-intractable asthma. These findings indicate that lymphocytes in lugns sensitized with Candida antigen might play an important role in the pathogenesis of non-atopic and intractable asthma. en-copyright= kn-copyright= en-aut-name=TakadaSho en-aut-sei=Takada en-aut-mei=Sho kn-aut-name=武田昌 kn-aut-sei=武田 kn-aut-mei=昌 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=気管支喘息 kn-keyword=気管支喘息 en-keyword=リンパ球幼若化反応 kn-keyword=リンパ球幼若化反応 en-keyword=bronchoalveolar lavage kn-keyword=bronchoalveolar lavage en-keyword=Candida kn-keyword=Candida en-keyword=mite kn-keyword=mite END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=9-10 article-no= start-page=915 end-page=922 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Development of double cancer in small cell lung cancer patients treated with intensive chemotherapy kn-title=肺小細胞癌化学療法実施例における重複癌の発生に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Development of double cancer was evaluated in 337 small cell lung cancer patients who had received intensive chemotherapy with or without radiotherapy.

The relative risk for the development of double cancer calculated by person-year method utilizing age and sex adjusted cancer incidence in Japan was 2.75-fold (P<0.01). The risk of non-small cell lung cancer (8.75-fold) and acute myelogenous leukemia (37.82-fold) was particularly high. The cumulative risk for the development of double cancer was 2.0% at 1 year, 4.1% at 2 years, 14.3% at 3 years, and 100% at 8.1 years. Of 27 patients who survived disease-free for more than 2 years, 10 patients died; five patients (50%) died of double cancer, two died of infectious disease, and only three patients died from recurrent small cell lung cancer. These findings indicate that a cautious follow-up program for the detection of double cancer is indicated in patients with small cell lung cancer. en-copyright= kn-copyright= en-aut-name=MiyakeKenichi en-aut-sei=Miyake en-aut-mei=Kenichi kn-aut-name=三宅賢一 kn-aut-sei=三宅 kn-aut-mei=賢一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=肺小細胞癌 kn-keyword=肺小細胞癌 en-keyword=化学療法 kn-keyword=化学療法 en-keyword=重複癌 kn-keyword=重複癌 END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=1-2 article-no= start-page=83 end-page=95 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=1992 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on laser photocoagulation for retinopathy of prematurity kn-title=レーザー光凝固による未熟児網膜症の治療に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Forty eyes in twenty-two cases in the active phase of retinopathy of prematurity were treated with laser photocagulation. Thiry (93.7%) of the 32 eyes in type I and intermediate type were found in the cicartrical phase grade 1. In type Ⅱ in which cryocautery was used as combination therapy, only 2 eyes (25.0%) were found in grade 1, 2 eyes (25.0%) in grade 2, 1 eye (12.5%) in grade 4 and 3 eyes (37.5%) in grade 5. All 21 eyes in which photocoagulation was performed up to the middle of stage 3 were found in grade 1 (100%). However, among 11 eyes in which photocoagulation were performed in late stage 3, 9 eys (81.8%) were found in grade 1, and 2 eyes (18.2%) in grade 2. In conclusion, if adequate laser photocoagulation is performed in avascular ares at the middle of stage 3 of type Ⅰ and intermediate type, treatment in cicartrical phase grade 1 is possible. Laser photocoagulation is clearly more effective than the xenon are photocoagula-tion or cryocautery. However, in type Ⅱ it is difficult to control the condition by photocagulation alone, and early diagnosis followed by combination therapy using cryocautery is reqired. en-copyright= kn-copyright= en-aut-name=OhtakiChiaki en-aut-sei=Ohtaki en-aut-mei=Chiaki kn-aut-name=大滝千秋 kn-aut-sei=大滝 kn-aut-mei=千秋 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部眼科学教室 en-keyword=未熟児網膜症 kn-keyword=未熟児網膜症 en-keyword=レーザー光凝固 kn-keyword=レーザー光凝固 END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=9-10 article-no= start-page=885 end-page=895 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The effect of nutritional intake on energy metabolism in postoperative patients after gastrointestinal surgery kn-title=間接熱量測定による消化器手術後のエネルギー代謝の検討―投与量・投与経路の比較― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Many studies have shown that enteral nutrition (EN) has nutritional effects comparable to total parenteral nutrition (TPN). However, the energy metabolism of the two different nutritioanl methods remains undefined. The two nutritional methods were compared by measuring the resting energy expenditure (REE) and nutritional assessment in postoperative patients after gastrointestinal surgery. The effects of different amounts of EN were also evaluated. Patients were diveded into three groups : Patients who were fed by EN of 30 Cal/kg/day (Group I, EN 30 : n=8), patients who were fed by EN of 40 Cal/kg/day (Group II, EN 40 : n=8), and patients who were fed by TPN of 30 Cal/kg/day (Group III, TPN : n=8). REE was measured by the Datex indirect calorimetry and nutritional assessment included the measurements of triceps skinfold thickness (TSF), arm muscle circumference (AMC), albumin and rapid turnover proteins. %REE/BEE of EN30, EN40 and TPN was 122.5±14.3%, 138.2±16.8% and 107.6±10.5% respectively. The RQ for the three groups was about 1.0, which means the energy source of all regimens is carbohydrate. The TPN group showed a significantly higher RQ than the EN groups, but there was no difference in albumin or transferrin. There was no difference in nutritional effect between EN 30 and EN 40. No difference was found in anthropometric effects among the three groups. These findings suggest that 30 Cal/kg/day would be preferable to 40 Cal/kg/day in energy supply of enteral nutrition and that the energy expenditure of EN is higher than that of TPN under 30 Cal/kg/day nutrition. There is no difference among the three mehtods in terms of nutritional effects. en-copyright= kn-copyright= en-aut-name=YoshizaneKen en-aut-sei=Yoshizane en-aut-mei=Ken kn-aut-name=吉實憲 kn-aut-sei=吉實 kn-aut-mei=憲 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二外科学教室 en-keyword=間接熱量計 kn-keyword=間接熱量計 en-keyword=経腸栄養 kn-keyword=経腸栄養 en-keyword=経静脈栄養 kn-keyword=経静脈栄養 en-keyword=代謝熱量 kn-keyword=代謝熱量 END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=5-6 article-no= start-page=663 end-page=668 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=1994 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Senile diabetes mellitus complicated with celiac arterial obliteration and heaptocellular carinoma : A case report kn-title=腹腔動脈完全閉塞をきたした肝細胞癌合併高齢者糖尿病の興味ある一例 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a 75-year-old female with diabetes mellitus complicated with celiac arterial obliteration and hepatocellular cercinoma (HCC).

Sine the deterioration of the liver function was not conspicuous, it was suggested that the development of HCC was affected by diabetes mellitus. en-copyright= kn-copyright= en-aut-name=OkaTakahiko en-aut-sei=Oka en-aut-mei=Takahiko kn-aut-name=岡隆彦 kn-aut-sei=岡 kn-aut-mei=隆彦 aut-affil-num=1 ORCID= en-aut-name=TomodaJun en-aut-sei=Tomoda en-aut-mei=Jun kn-aut-name=友田純 kn-aut-sei=友田 kn-aut-mei=純 aut-affil-num=2 ORCID= en-aut-name=KobashiHaruhiko en-aut-sei=Kobashi en-aut-mei=Haruhiko kn-aut-name=小橋春彦 kn-aut-sei=小橋 kn-aut-mei=春彦 aut-affil-num=3 ORCID= en-aut-name=SakaiNobuyuki en-aut-sei=Sakai en-aut-mei=Nobuyuki kn-aut-name=坂井宣行 kn-aut-sei=坂井 kn-aut-mei=宣行 aut-affil-num=4 ORCID= en-aut-name=SakaguchiKohsaku en-aut-sei=Sakaguchi en-aut-mei=Kohsaku kn-aut-name=坂口孝作 kn-aut-sei=坂口 kn-aut-mei=孝作 aut-affil-num=5 ORCID= en-aut-name=YamamotoKazuhide en-aut-sei=Yamamoto en-aut-mei=Kazuhide kn-aut-name=山本和秀 kn-aut-sei=山本 kn-aut-mei=和秀 aut-affil-num=6 ORCID= en-aut-name=HigashiToshihiro en-aut-sei=Higashi en-aut-mei=Toshihiro kn-aut-name=東俊宏 kn-aut-sei=東 kn-aut-mei=俊宏 aut-affil-num=7 ORCID= en-aut-name=ItoToshio en-aut-sei=Ito en-aut-mei=Toshio kn-aut-name=伊藤俊雄 kn-aut-sei=伊藤 kn-aut-mei=俊雄 aut-affil-num=8 ORCID= en-aut-name=YamadaGotaro en-aut-sei=Yamada en-aut-mei=Gotaro kn-aut-name=山田剛太郎 kn-aut-sei=山田 kn-aut-mei=剛太郎 aut-affil-num=9 ORCID= en-aut-name=TsujiTakao en-aut-sei=Tsuji en-aut-mei=Takao kn-aut-name=辻孝夫 kn-aut-sei=辻 kn-aut-mei=孝夫 aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第一内科学教室 affil-num=2 en-affil= kn-affil=岡山大学医学部第一内科学教室 affil-num=3 en-affil= kn-affil=岡山大学医学部第一内科学教室 affil-num=4 en-affil= kn-affil=岡山大学医学部第一内科学教室 affil-num=5 en-affil= kn-affil=岡山大学医学部第一内科学教室 affil-num=6 en-affil= kn-affil=岡山大学医学部第一内科学教室 affil-num=7 en-affil= kn-affil=岡山大学医学部第一内科学教室 affil-num=8 en-affil= kn-affil=岡山大学医学部第一内科学教室 affil-num=9 en-affil= kn-affil=岡山大学医学部第一内科学教室 affil-num=10 en-affil= kn-affil=岡山大学医学部第一内科学教室 en-keyword=糖尿病 kn-keyword=糖尿病 en-keyword=腹腔動脈閉塞 kn-keyword=腹腔動脈閉塞 en-keyword=肝細胞癌 kn-keyword=肝細胞癌 en-keyword=動脈硬化 kn-keyword=動脈硬化 END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=7-8 article-no= start-page=789 end-page=795 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The relationships between physique and throwing ability in high school baseball players kn-title=高校野球選手における形態と投能力の関係 en-subtitle= kn-subtitle= en-abstract= kn-abstract=There is little information on anthropometric measures (i. e., length, breadth and girth of body's parts) related to throwing ability. To clarify the influence of the physique on the throwing ability, the relationships between physique and throwing distance, as well as ball speed were investigated. The subjects were fourty-nine high school baseball players, and thirty-eight high school volleyball players, football players and canoeists served as a control group. The throwing distance was significantly related to lean body mass (r=.290), chest girth (r=.416), upper arm girth (r=.307), abdominal girth (r=.288), thigh girth (r=.327) and lower leg girth (r=.285) in baseball players group (p<0.05-0.01). A significant relationship between the throwing distance and foot length in control group (r=.329, p<0.05) was demonstrated. Significant relationships between ball speed and standing height in the baseball players group (r=.354, p<0.01) and that between ball speed and Impedance in the control group (r=-.288, p<0.05) were ovserved. These findings indicate that the throwing distance is influenced by quantity of body muscle in baseball players. There was no relation between physique and throwing ability in unskilled players. en-copyright= kn-copyright= en-aut-name=UchidaHayato en-aut-sei=Uchida en-aut-mei=Hayato kn-aut-name=内田勇人 kn-aut-sei=内田 kn-aut-mei=勇人 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部衛生学教室 en-keyword=野球選手 kn-keyword=野球選手 en-keyword=形態 kn-keyword=形態 en-keyword=遠投距離 kn-keyword=遠投距離 en-keyword=ボールスピード kn-keyword=ボールスピード en-keyword=Impedance kn-keyword=Impedance END start-ver=1.4 cd-journal=joma no-vol=104 cd-vols= no-issue=7-8 article-no= start-page=763 end-page=775 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199208 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the role of neutrophils in intractable asthma Part 1.

The production of leukotrienes (LTs) and superoxide stimulated by the calcium ionophores (CaI) from neutrophil-rich fraction of 29 intractable, 70 non-intractable asthmatics and 18 healthy subjects was examined by high performance liquid chromatography and a cytochrome C reduction method. Significantly larger amounts of LTC(4) and LTB(4) were produced by CaI in the neutrophil-rich fraction from asthematics, than in that from the healthy subjects (p<0.01). Moreover, a significantly larger amounts of LTC(4) was producted in the fraction obtained from the intractable asthmatics than in that from the non-intractable asthmatics (p<0.05). However, there was no significant difference in LTB(4) production between the two groups of asthmatics. The production of superoxide by concanavalin A was significantly increased in the neutrophil-rich fraction from prednisolone-within-10mg-dependent asthmatics than in those from prednisolone-over-10mg-dependent patients (p<0.01). There were correlations between the LTC(4) and LTB(4) production, and also between LTB(4) and superoxide production. LTs and superoxide released from inflammatory cells, especially neutrophils, may play an important role in the pathgenesis of intractable asthma. en-copyright= kn-copyright= en-aut-name=ShimizuIkki en-aut-sei=Shimizu en-aut-mei=Ikki kn-aut-name=清水一紀 kn-aut-sei=清水 kn-aut-mei=一紀 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=難治性喘息 kn-keyword=難治性喘息 en-keyword=好中球 kn-keyword=好中球 en-keyword=ロイコトリエン kn-keyword=ロイコトリエン en-keyword=スーパーオキサイド kn-keyword=スーパーオキサイド END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=7 article-no= start-page=723 end-page=728 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=20041022 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Separation and determination of n-alkylamines by reversed-phase high-performance liquid chromatography coupled with merging zone derivatization to water-soluble Schiff bases kn-title=水溶性シッフ塩基へのマージングゾーン誘導体化/逆相分配高速液体クロマトグラフィーによるn-アルキルアミン類の分離定量 en-subtitle= kn-subtitle= en-abstract=n-アルキルアミン類の分離定量法として,陰イオン性アルデヒドを誘導体化試薬として用いる吸光検出-逆相分配高速液体クロマトグラフィーを検討した.誘導体化試薬としては,サリチルアルデヒド-5-スルホン酸イオン(SAS)と4-(4-スルホフェニルアゾ)-1-ヒドロキシ-2-ナフトアルデヒド(SPAHNA)を用いた.n-アルキルアミンを含む試料溶液と試薬溶液はそれぞれの流路に同時に注入され,マージングゾーン法によりオンラインで混合され,5 m,70℃ の反応コイル中で水溶性シッフ塩基へと誘導体化された.生成した水溶性シッフ塩基は逆相カラムにより分離され,吸光検出された.オンライン誘導体化とカラム分離/検出を含む分析時間は,SASを用いた場合25分,SPAHNAを用いた場合は18分であった.アルキルアミン類に対する検量線は0~50 μMの範囲で良好な直線性が得られ,検出限界は,SASを用いた場合0.5~1.0 μM,SPAHNAを用いた場合は0.08~0.20 μMであった. kn-abstract=Separation and determination of n-alkylamines were investigated with anionic aldehydes to form water-soluble Schiff bases by using reversed-phase high-performance liquid chromatography (RP-HPLC).

By using the platinum tube reactor (0.5 mm i.d.×3 m), a standard sample, D-glucose, was measured within a few minutes, and the calibration graph was linear from 0 to 100 ppm of COD(D-glucose); the detection limit corresponding to S/N = 3 was 0.01 ppm. The relative standard deviations for 5, 10, 50 and 100 ppm of COD(D-glucose) were 0.9, 0.8, 0.8, 0.5 and 1.4%, respectively.

These two compounds and purchased diethyl- and dipropyl-2,2'-thiacyanine were examined for the spectrophotometric determination of an anionic surfactant, DBS.

Control rabbits inhaled radon water from the same springs which had been kept for over 10 radon half-life periods. TPR was evaluated 15 minutes after the beginning of inhalation by mass spectrometry. After inhalation for 90 minutes, plasma and adrenal glands were removed, and levels of adrenaline and noradrenaline were analyzed by high-performance liquid chromatography (THI mithod). Each group was divided into 4 subgroups according to intravenously injected medication as follows : 1) no medication (without adrenergic blocker), 2) phentolamine (α-blocker), 0.05mg/kg/min, 3) propranolol (non-selective β-blocker), 1mg/kg, and 4) atenolol (selective β1-blocker), 6mg/kg. In the radon group, plasma adrenaline and noradrenaline levels were significantly higher (p<0.01, p<0.05), and adrenaline and noradrenaline levels were significantly lower (p<0.01, P<0.01), than those in the control group. In the no medication and phentolamine subgroups, TPRs in the radon group were significantly higher than those in the control group (p<0.01, P<0.01). In the propranolol and atenolol subgroups, no significant change of TPR was found. It is suggested that catecholamines are secreted from the adrenal glands upon inhalation of radon water and that the β1-action of catecholamines contributes to the increase in tissue perfusion. en-copyright= kn-copyright= en-aut-name=SuzukaIchio en-aut-sei=Suzuka en-aut-mei=Ichio kn-aut-name=鈴鹿伊智雄 kn-aut-sei=鈴鹿 kn-aut-mei=伊智雄 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部心臓血管外科学教室 en-keyword=ラドン水 kn-keyword=ラドン水 en-keyword=副腎髄質 kn-keyword=副腎髄質 en-keyword=カテコラミン kn-keyword=カテコラミン en-keyword=組織循環 kn-keyword=組織循環 en-keyword=ホルミシス kn-keyword=ホルミシス END start-ver=1.4 cd-journal=joma no-vol=54 cd-vols= no-issue=10 article-no= start-page=953 end-page=957 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=20041222 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Determination of Trace Amounts of Ammonia in Air Using a Batchwise Collection/Concentration Method by Spectrophotometry kn-title=簡易捕集濃縮/吸光光度法による大気中微量アンモニアの定量 en-subtitle= kn-subtitle= en-abstract=Ammonia in the atmosphere can be determined by an improved indophenol method with 1-naphthol. Ammonia dissolved in water reacts with sodium hypochlorite in the presence of sodium hydroxide and 1-naphthol to form an indophenol blue dye, which can be measured at 720 nm (maximum absorbance). Since ammonia in the atmosphere can be absorbed in purified water almost completely, a calibration graph using standard aqueous ammonium chloride solutions can be used. The calibration graph showed a good linearity (y = 0.37 × 10(5)x+0.027, R(2) = 0.9992) and the detection limit was 0.9 × 10(−6) M. For practical samples, the air was collected into a 50 ml plastic syringe with an air-tight cap containing 3.0 ml of purified water as the absorbing solution, followed by shaking it by hand. The method was successfully applied to the determination of ammonia in indoor and outdoor air samples. kn-abstract=大気中のアンモニア定量法として1-ナフトールを用いるインドフェノール法を検討した.水溶液中のアンモニアは水酸化ナトリウム存在下で次亜塩素酸ナトリウム,1-ナフトールと反応し,インドフェノール型色素を生成する.この生成物の極大吸収波長である720 nmで吸光度を測定すること(1-ナフトール法)により,大気中のアンモニアを定量した.塩化アンモニウム標準溶液を用いる検量線は良好な直線性を示し(y=0.37 × 105 x+0.027,R(2)=0.9992),検出限界は0.9 × 10(-6) Mであった.アセトンを10% 加えることにより,均一溶液中で既報の約5倍の感度が得られた.2.0 × 10(-5) M塩化アンモニウム標準溶液を用いた場合の相対標準偏差は3.5% と良好であった.実試料への応用として,超純水3.0 mlを入れた50 mlプラスチック製シリンジ(実体積: 69.1±0.3 ml)に大気試料を捕集し,シリンジにキャップをして4分間振り混ぜた.大気中のアンモニアは吸収溶液として用いた超純水にほぼ完全に捕集濃縮できた.吸収したアンモニアを1-ナフトール法で測定した.本法は室内,屋外の大気中微量アンモニア定量に十分な精度と感度を示した. en-copyright= kn-copyright= en-aut-name=SuekaneTakashi en-aut-sei=Suekane en-aut-mei=Takashi kn-aut-name=末包高史 kn-aut-sei=末包 kn-aut-mei=高史 aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院自然科学研究科理学系 affil-num=2 en-affil= kn-affil=岡山大学大学院自然科学研究科理学系 affil-num=3 en-affil= kn-affil=岡山大学大学院自然科学研究科理学系 en-keyword=ammonia kn-keyword=ammonia en-keyword=1-naphthol kn-keyword=1-naphthol en-keyword=air sample kn-keyword=air sample en-keyword=spectrophotometry kn-keyword=spectrophotometry END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=9 article-no= start-page=1039 end-page=1043 dt-received= dt-revised= dt-accepted= dt-pub-year=2004 dt-pub=20041224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Synthesis of iminodi(methylphosphonic acid)-type chitosan resin and its adsorption behavior for trace metals kn-title=イミノ二メチルホスホン酸型キトサン樹脂の合成と微量金属の捕集挙動 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A chitosan-based resin possessing the iminodi(methylphosphonic acid) moiety (IDP-type chitosan resin) was synthesized by using cross-linked chitosan as a base material.

Uranium(VI) and thorium could not be eluted with nitric acid and hydrochloric acid (1∼6 M); other metal ions were easily and readily eluted with 1 M nitric acid. The IDP-type chitosan resin synthesized in this work can be applied to the separation of U(VI) and Th(IV) from other metal ions. en-copyright= kn-copyright= en-aut-name=YamakawaSatoko en-aut-sei=Yamakawa en-aut-mei=Satoko kn-aut-name=山川聡子 kn-aut-sei=山川 kn-aut-mei=聡子 aut-affil-num=1 ORCID= en-aut-name=OshitaKoji en-aut-sei=Oshita en-aut-mei=Koji kn-aut-name=大下浩司 kn-aut-sei=大下 kn-aut-mei=浩司 aut-affil-num=2 ORCID= en-aut-name=AkhmadSabarudin en-aut-sei=Akhmad en-aut-mei=Sabarudin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=4 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部化学科 affil-num=2 en-affil= kn-affil=岡山大学理学部化学科 affil-num=3 en-affil= kn-affil=岡山大学理学部化学科 affil-num=4 en-affil= kn-affil=岡山大学理学部化学科 affil-num=5 en-affil= kn-affil=岡山大学理学部化学科 en-keyword=chitosan resin kn-keyword=chitosan resin en-keyword=iminodi(methylphosphonic acid (IDP) kn-keyword=iminodi(methylphosphonic acid (IDP) en-keyword=uranium(VI) kn-keyword=uranium(VI) en-keyword=thorium(IV) kn-keyword=thorium(IV) en-keyword=heavy metals kn-keyword=heavy metals END start-ver=1.4 cd-journal=joma no-vol=55 cd-vols= no-issue=9 article-no= start-page=707 end-page=713 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20061117 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Development of Computer-Controlled Flow Injection Instruments and Its Application to Determination of Nitrate, Nitrite, and Ammonium Ions in Environmental Samples kn-title=コンピュータ制御されたフローインジェクション分析装置の開発と環境水中の硝酸イオン,亜硝酸イオン,アンモニウムイオン定量への応用 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Flow injection analysis (FIA) systems with low power consumption and personal-computer control were developed by using solenoid pumps and an LED detector.

Linear calibration graphs were obtained with the combination of pump(s) and photometric detector in the concentration range of nitrite ion at 0.5∼3.0 × 10−6 M. Nitrate and nitrite ions were also determined simultaneously by the system by using a Cd/Cu reduction column and a by-pass flow. Determination of ammonia in river-water samples was also realized by the system with a modified indophenol reaction. en-copyright= kn-copyright= en-aut-name=JoichiYasutaka en-aut-sei=Joichi en-aut-mei=Yasutaka kn-aut-name=城市康隆 kn-aut-sei=城市 kn-aut-mei=康隆 aut-affil-num=1 ORCID= en-aut-name=NarongLenghor en-aut-sei=Narong en-aut-mei=Lenghor kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name=高柳俊夫 kn-aut-sei=高柳 kn-aut-mei=俊夫 aut-affil-num=3 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=4 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=5 ORCID= en-aut-name=UraNobuo en-aut-sei=Ura en-aut-mei=Nobuo kn-aut-name=浦信夫 kn-aut-sei=浦 kn-aut-mei=信夫 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部化学科 affil-num=2 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=3 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=4 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=5 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=6 en-affil= kn-affil=株式会社相馬光学 en-keyword=Flow injection analysis kn-keyword=Flow injection analysis en-keyword=LabVIEW control kn-keyword=LabVIEW control en-keyword=solenoid pumps kn-keyword=solenoid pumps en-keyword=nitrate ion kn-keyword=nitrate ion en-keyword=nitrite ion kn-keyword=nitrite ion en-keyword=ammonia kn-keyword=ammonia END start-ver=1.4 cd-journal=joma no-vol=55 cd-vols= no-issue=9 article-no= start-page=715 end-page=720 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20061117 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Highly Efficient and Automatic Collection/Concentration with Chelating Resin for Inductively Coupled Plasma Atomic Emission Spectroscopy kn-title=誘導結合プラズマ発光分析のためのキレート樹脂を用いる高効率自動前処理濃縮 en-subtitle= kn-subtitle= en-abstract= kn-abstract=An automatically controlled collection/concentration system for ICP-AES was developed. Elements were collected with small chelating disks and chelating resin with the iminodiacetate moiety packed in a line filter. This column was installed in a 6-way valve on the pretreatment system, which could be connected on line to ICP-AES. The flow rate was 1 ml min−1 and conditioning of the chelating disk was carried out by flowing 0.5 M ammonium acetate (pH 5.5) for 2 min, sampling for 5 min and washing for 1 min. Elution was done by passing through 2 M HNO3 at 1.3 ml min−1 for 1 min. Bi, Cd, Co, Cr, Cu, Mn, Ni, Pb and V could be determined with 5.0 ml of the sample solution. The enrichment factors were 3∼15 times and the collection efficiencies were better than 80%. The detection limits (LOD) were from 0.003 for Mn to 0.311 for Bi, which were several 10 to 100-times lower than that of normal LOD of ICP-AES. This method was successfully applied to the determination of these metals in tap and river-water samples. en-copyright= kn-copyright= en-aut-name=YamamotoTakako en-aut-sei=Yamamoto en-aut-mei=Takako kn-aut-name=山本貴子 kn-aut-sei=山本 kn-aut-mei=貴子 aut-affil-num=1 ORCID= en-aut-name=AkhmadSabarudin en-aut-sei=Akhmad en-aut-mei=Sabarudin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NoguchiOsamu en-aut-sei=Noguchi en-aut-mei=Osamu kn-aut-name=野口修 kn-aut-sei=野口 kn-aut-mei=修 aut-affil-num=3 ORCID= en-aut-name=TakayanagiToshio en-aut-sei=Takayanagi en-aut-mei=Toshio kn-aut-name=高柳俊夫 kn-aut-sei=高柳 kn-aut-mei=俊夫 aut-affil-num=4 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=5 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学理学部化学科 affil-num=2 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=3 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=4 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=5 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 affil-num=6 en-affil= kn-affil=岡山大学大学院自然科学研究科機能分子化学専攻 en-keyword=automated collection/concentration kn-keyword=automated collection/concentration en-keyword=chelating disk and chelating resin kn-keyword=chelating disk and chelating resin en-keyword=ICP-AES kn-keyword=ICP-AES en-keyword=heavy metals kn-keyword=heavy metals END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=4 article-no= start-page=505 end-page=508 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20080410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spectrophotometric Determination of 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide Hydrochloride by Flow Injection Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC·HCl) is a very useful agent to form amide bonds (peptide bonds) in an aqueous medium.

The absorbances were measured at 400 nm and the reaction was accelerated at 40˚C. The calibration graph showed good linearity from 0 to 10% of EDC·HCl solutions: the regression equation was y = 3.15 × 104x (y, peak area; x, % concentration of EDC·HCl). The RSD was under 1.0%. Sample throughput was 15 h–1. This method was applied to monitoring the EDC·HCl concentration that remained after the anhydration of phthalic acid in water, esterification of acetic acid in methanol or dehydration condensation of malonic acid and ethylenediamine in water. en-copyright= kn-copyright= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KunihikoSeno kn-aut-sei=Kunihiko kn-aut-mei=Seno aut-affil-num=1 ORCID= en-aut-name= en-aut-sei= en-aut-mei= kn-aut-name=KazukiMatsumura kn-aut-sei=Kazuki kn-aut-mei=Matsumura aut-affil-num=2 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=3 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=4 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 affil-num=4 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=5 article-no= start-page=631 end-page=635 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=20080510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Minimization of Sample Volume with Air-segmented SampleInjection and the Simultaneous Determination of TraceElements by ICP-MS en-subtitle= kn-subtitle= en-abstract= kn-abstract=The application of inductively coupled plasma mass spectrometry (ICP-MS) to forensic chemistry was studied.

The optimum sample flow rate was found to be 0.4 ml min–1, along with a sample suction time of 30 s. The proposed method was validated by determining trace elements in river-water certified reference material (SLRS-4) issued by National Research Council Canada. The analytical results of the proposed method were in good agreement with the certified values. This method was successfully applied to a human hair sample, the volume of which was 3 ml. en-copyright= kn-copyright= en-aut-name=NoguchiOsamu en-aut-sei=Noguchi en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OshimaMitsuko en-aut-sei=Oshima en-aut-mei=Mitsuko kn-aut-name=大島光子 kn-aut-sei=大島 kn-aut-mei=光子 aut-affil-num=2 ORCID= en-aut-name=MotomizuShoji en-aut-sei=Motomizu en-aut-mei=Shoji kn-aut-name=本水昌二 kn-aut-sei=本水 kn-aut-mei=昌二 aut-affil-num=3 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil=岡山大学 affil-num=3 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=109 cd-vols= no-issue=1-2 article-no= start-page=25 end-page=33 dt-received= dt-revised= dt-accepted= dt-pub-year=1997 dt-pub=19970228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Clinical studies on choroidal circulatory disturbance : Relationship between central cerous chorioretinopathy and choroidal circulatory disturbance kn-title=脈絡膜循環障害に関する臨床的研究―中心性漿液性脈絡網膜症と脈絡膜循環障害の関連について― en-subtitle= kn-subtitle= en-abstract= kn-abstract=In order to know frequency of choroidal circulatory disturbance, 126 eyes with central serouse chorioretinopathy followed-up between Jan. 1985 and Dec. 1990 were retrospectively investigated by fundus fluorescein angiography. Appearance of choroidal circulatory disturbance was divided into two types. The type 1 showed choroidal filling delay at late retinal venous phase. The type 2 showed mosaic pattern of choroidal background at late retinal venous phase. Among the 126 eyes, 3 eyes were type 1 (2.4%) and 57 eyes were type 2 (45.2%), totaling 60 eyes (47.6%). Sixty-three eyes with normal part of branch retinal vein occlusion matching in sex and age were selected as controls. In the controls, no eye was type 1 (0%) and 8 eyes were type 2 (12.7%), totaling 8 eyes (12.7%). Distinctly, proportion of the type 2 was higher in central serous chorioretinopathy than in branch retinal vein occlusion. In conclusion, the pathogenesis of central serous chorioretinopathy is related to choroidal circulatory disturbance and especially mosaic pattern (type 2) was found to be a new type of circulatory disturbance. en-copyright= kn-copyright= en-aut-name=KawanishiYouko en-aut-sei=Kawanishi en-aut-mei=Youko kn-aut-name=河西葉子 kn-aut-sei=河西 kn-aut-mei=葉子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部眼科学教室 en-keyword=中心性漿液性脈絡網膜症 kn-keyword=中心性漿液性脈絡網膜症 en-keyword=フルオレセイン螢光造影 kn-keyword=フルオレセイン螢光造影 en-keyword=充盈遅延 kn-keyword=充盈遅延 en-keyword=モザイク模様 kn-keyword=モザイク模様 END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=7-8 article-no= start-page=907 end-page=915 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Establishment of antigen specific T cell clones from asthmatic patients including evaluation of cytokine production kn-title=気管支喘息における抗原特異的 T cell clone の樹立とサイトカイン産生能に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the pathogenesis of bronchial asthma, we establishied T cell clones specific for Candida antigen and for mite antigen from the peripheral blood of three asthmatic patients. Flow cytometric analysis was performed on these clones. The surface phenotype of all clones was helper/inducer type. These clones were analyzed for the ability to produce interferon gammma (IFN-γ) and interleukin 4 (IL-4). The T cell clone established from tne patient who showed late asthmatic response (LAR) after bronchial inhalation of Candida, as well as the clones from the patient who showed IAR and LAR after inhalation of housedust mite, produced a higher amount of IFN-γ and lower amount of IL-4. The T cell clone established from the patient who were under corticosteroid therapy and showed IAR after inhalation of Candida produced lower amounts of IFN-γ and IL-4, which seemed to be inhibition of cytokine production from antigen specific T cell clone by corticosteroids. These findings indicate that T cell clones established from the patients who showed LAR produced a large amount of IFN-γ, suggesting that IFN-γ plays an important role in allergic reactions of LAR. en-copyright= kn-copyright= en-aut-name=MiyaharaNobuaki en-aut-sei=Miyahara en-aut-mei=Nobuaki kn-aut-name=宮原信明 kn-aut-sei=宮原 kn-aut-mei=信明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=antigen specific T cell clone kn-keyword=antigen specific T cell clone en-keyword=IFN-γ kn-keyword=IFN-γ en-keyword=bronchial asthma kn-keyword=bronchial asthma en-keyword=late asthmatic response (LAR) kn-keyword=late asthmatic response (LAR) END start-ver=1.4 cd-journal=joma no-vol=106 cd-vols= no-issue=7-8 article-no= start-page=743 end-page=750 dt-received= dt-revised= dt-accepted= dt-pub-year=1994 dt-pub=199408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the occurrence of bronchial asthma Part 2.

CMV-induced lymphocyte reactivity (CMV-LR) in adult asthmatics was significantly higher than that in the healthy controls. A positive correlation was observed between CMV-LR titer and CMV-complement fixation (CMV-CF) antibody titers (r=0.35). In adult asthmatics, the CMV-LR in the high IgE titer (100U/ml≦) group was significantly higher than that in the low IgE titer (<100U/ml) group. These findings suggest that CMV is an important factor in the pathogenesis of adult asthma mediated by lymphocytes and probably IgE, although the precise mechanism in still unknown. en-copyright= kn-copyright= en-aut-name=OkamotoMakoto en-aut-sei=Okamoto en-aut-mei=Makoto kn-aut-name=岡本誠 kn-aut-sei=岡本 kn-aut-mei=誠 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部第二内科学教室 en-keyword=bronchial asthma kn-keyword=bronchial asthma en-keyword=viral infection kn-keyword=viral infection en-keyword=Cytomegalovirus kn-keyword=Cytomegalovirus en-keyword=IgE kn-keyword=IgE en-keyword=CMV-LTT kn-keyword=CMV-LTT END start-ver=1.4 cd-journal=joma no-vol=108 cd-vols= no-issue=7-8 article-no= start-page=215 end-page=223 dt-received= dt-revised= dt-accepted= dt-pub-year=1996 dt-pub=19960831 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Serum levels of macrophage colony stimulating factor and other acute phase reactants after open heart surgery kn-title=開心術後における Macrophage Colony-Stimulating Factor と急性相反応物質の血中動態について en-subtitle= kn-subtitle= en-abstract= kn-abstract=To clarify the phathophysiological role of macrophage colony stimulating factor (M-CSF) in the healing processes of inflammation, we studied chronological changes in serum concentrations of M-CSF and other reactants during the acute phase of inflammation in patients who underwent open heart surgery, since these patients showed a precise point of tissue damage. The number of neutrophilic leukocytes increased in the very early postoperative stage, reached a peak 48 h after surgery and declined to the basal level at day 14. The chronological changes in serum C-reactive protein level after surgery were similar to these of neutrophic leukocytes. Serum M-CSF concentrations increased gradually, reached a peak 7 days after surgery and remained at that level until day 14. Based on these phenomena, it is assumed that M-CSF plays a pathophysiological role in the healing processes of an inflammation. Measurement of the serum concentration of M-CSF would be useful for evaluating the process of inflammation. en-copyright= kn-copyright= en-aut-name=ChikakiyoHirokazu en-aut-sei=Chikakiyo en-aut-mei=Hirokazu kn-aut-name=近清裕一 kn-aut-sei=近清 kn-aut-mei=裕一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部公衆衛生学教室 en-keyword=M-CSF kn-keyword=M-CSF en-keyword=開心術 kn-keyword=開心術 en-keyword=白血球数 kn-keyword=白血球数 en-keyword=急性相反応物質 kn-keyword=急性相反応物質 en-keyword=サイトカイン kn-keyword=サイトカイン END start-ver=1.4 cd-journal=joma no-vol=112 cd-vols= no-issue=9-12 article-no= start-page=183 end-page=189 dt-received= dt-revised= dt-accepted= dt-pub-year=2000 dt-pub=20001225 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=An investigation into the factors of smoking cessation in male smokers kn-title=男性喫煙者の禁煙実行要因に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract=This syudy was designed to clarify what factors influenced the ability to stop smoking in male smokers, from the viewpoint of life-style guidance and primary care. Of the people who attended abult health examinations between 1993 and 1998 in Okayama Ctiy, 987 male smokers were selected and categorized according to the number of cigarettes per day into three groups. The relation was analyzed statistically between the three groups and the life-style related factors : age, the degree of obesity, sleep, snacks, salt, exercise and alcohol. The results showed significant differences in age, the degree of obesity, sleep, salt, exercise. Second, the relation between threse three groups and the experience and duration of smoking cessation was analyzed. The results showed a significant differnce in the experience of smoking cessation, but no significant differnce in duration of smoking cessation. The conclusions are as follows : 1. Male smokers, who do not activedy try to improve of their life-style related factors, have fewer experiences of smoking cessation, 2. Male smokers who try to improve their life-style habits have a similar period od smoking cessation to those who do not. 3. Long term support for all male smokers to continue to be non-smoking is important. en-copyright= kn-copyright= en-aut-name=KawadaYuichi en-aut-sei=Kawada en-aut-mei=Yuichi kn-aut-name=川田諭一 kn-aut-sei=川田 kn-aut-mei=諭一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部衛生医学講座 en-keyword=喫煙本数 kn-keyword=喫煙本数 en-keyword=生活習慣 kn-keyword=生活習慣 en-keyword=健康意識 kn-keyword=健康意識 en-keyword=健康意欲 kn-keyword=健康意欲 en-keyword=禁煙経験 kn-keyword=禁煙経験 en-keyword=再喫煙 kn-keyword=再喫煙 END start-ver=1.4 cd-journal=joma no-vol=118 cd-vols= no-issue=1 article-no= start-page=41 end-page=45 dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20060501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Two cases of acute pulmonary embolism after esophageal cancer operation kn-title=早期診断し得た食道癌術後静脈血栓塞栓症の2例 en-subtitle= kn-subtitle= en-abstract= kn-abstract=We encountered two cases of pulmonary embolism (PE)/venous thrombs (DVT) after surgery for esophageal cancer. The first case was a 58-year-old male. He underwent a subtotal esophagectomy and reconstruction using the stomach via the subcutaneus route. His postoperative course was stable; however, 13 days after the operation、 he had an elevated fever and pulmonary thrombi were observed on CT-scan screening. Scintigraphy confirmed the thrombi. An inferior vena cava filter (IVCF) was inserted and anti-coagulation therapy using heparin was started. His fever subsided, and 35 days after the operation, the thrombi disappeared. He was discharged thereafter and is being followed up using warfarin. The second case was a 74-year-old male. He also underwent subtotal esophagectomy and reconstruction using the stomach via the subcutaneus route. A central line was inserted via right femoral vein; however, the artery was injured and pressurization to the vessel was needed. His post-operative course was stable and symptom-free; however, ultrasound screening detected DVT in his right femoral vein. IVCF was mserted and anti-coagulation therapy was begun, thrombi disappeared 8 days after the therapy. en-copyright= kn-copyright= en-aut-name=KanazawaTakashi en-aut-sei=Kanazawa en-aut-mei=Takashi

(1)4,6,8KRを照射した蛹は,正常のものと大差なく高い羽化率を示し,奇型の出現も少ない. (2)羽化2日前の蛹へ8KRを照射すると雄・雌成虫とも完全不妊となる. しかし,それらは正常雄・雌より生存日数がやや短かい傾向を示す. (3)10個の正常雌に対して正常雄10個とその20倍の8KR不妊化雄200個を組み合わせるとほとんど完全な不妊効果が示される. 15倍の150個以下では若干の孵化幼虫が発育して次代の成虫となる. (4)上記雄・雌成虫は正常の雌・雄と組み合わされたとき,比較的高い不妊を示す. (5)生存日数がやや短かいという欠点を補正するために,6KR不妊化雄をつくると,もちろん完全不妊ではない. また次代に発育ができた成虫も不妊性があまり期待できない. しかし6KR不妊化雄を正常雄の20倍,すなわち200個以上組み入れると比較的に高い不妊が得られる. (6)我が国における他の研究と比較して,X線,60Coおよび137Csガンマー線は実用的には大体おなじ線盤8KRでミカンコミバエを完全不妊にできることがわかった. (7)なお解剖観察によって8KR不妊化雄の不妊原因は精巣そのもの,精子の雌への移動,精子の活動力などの異常によるよりも優性致死変異に起因するものと推察された。 en-copyright= kn-copyright= en-aut-name=KiyokuMasao en-aut-sei=Kiyoku en-aut-mei=Masao kn-aut-name=清久正夫 kn-aut-sei=清久 kn-aut-mei=正夫 aut-affil-num=1 ORCID= en-aut-name=TsukudaRitsuko en-aut-sei=Tsukuda en-aut-mei=Ritsuko kn-aut-name=佃律子 kn-aut-sei=佃 kn-aut-mei=律子 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 affil-num=2 en-affil= kn-affil=岡山大学 END
