Recently, ferritin is pointed out to be related with oxidative stress. However, there is still no population research which showed the relation of CP and ferritin. Therefore, we investigated the relationship between CP and ferritin including oxidative stress biomarkers among healthy Japanese (n = 389). We measured serum CP, ferritin, Fe, high-sensitivity C-reactive protein (hs-CRP), and urinary oxidative stress biomarkers [H2O2, 8-hydroxy-2'-deoxyguanosine (8-OHdG), 8-isoprostane] and so on. Subjects showed that age; 41.7 ± 10.0 (year), CP; 31.9 ± 6.8 (mg/dl), ferritin; 123.5 ± 121.0 (ng/ml), hs-CRP; 0.89 ± 2.53 (mg/l), 8-OHdG; 10.2 ± 4.4 [ng/mg creatinine (Cre)] and H2O2; 6.5 ± 10.9 (µM/g Cre), (All data mentioned above were expressed as mean ± SD). CP was significantly and positively correlated with hs-CRP and inversely correlated with ferritin, Fe and 8-OHdG. By a multiple logistic regression analysis, odds ratio of CP according to quartiles of hs-CRP was 4.86, and according to quartiles of 8-OHdG was 0.39 after adjusting for age and other confounding factors. In conclusion, our findings suggest that CP was an antioxidative biomarker which controls oxidative stress, whereas ferritin was a marker which may participate in the generation of oxidative stress. en-copyright= kn-copyright= en-aut-name=InoueKiyomi en-aut-sei=Inoue en-aut-mei=Kiyomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakanoNoriko en-aut-sei=Sakano en-aut-mei=Noriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OginoKeiki en-aut-sei=Ogino en-aut-mei=Keiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatoYoshie en-aut-sei=Sato en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangDa-Hong en-aut-sei=Wang en-aut-mei=Da-Hong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KuboMasayuki en-aut-sei=Kubo en-aut-mei=Masayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakahashiHidekazu en-aut-sei=Takahashi en-aut-mei=Hidekazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanbaraSakiko en-aut-sei=Kanbara en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyatakeNobuyuki en-aut-sei=Miyatake en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Department of Hygiene, Faculty of Medicine, Kagawa University affil-num=3 en-affil= kn-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Perineito Hahatokono Hosp Mothers & Children, Dept Gynecol & Obstet affil-num=5 en-affil= kn-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=6 en-affil= kn-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=7 en-affil= kn-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=8 en-affil= kn-affil=Okayama Univ, Dept Pediat, Grad Sch Med Dent & Pharmaceut Sci affil-num=9 en-affil= kn-affil=Department of Hygiene, Faculty of Medicine, Kagawa University en-keyword=ceruloplasmin kn-keyword=ceruloplasmin en-keyword=ferritin kn-keyword=ferritin en-keyword=8-OHdG kn-keyword=8-OHdG en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=high-sensitivity C-reactive protein kn-keyword=high-sensitivity C-reactive protein END start-ver=1.4 cd-journal=joma no-vol=52 cd-vols= no-issue=1 article-no= start-page=27 end-page=31 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Thioredoxin-1 and oxidative stress status in pregnant women at early third trimester of pregnancy: relation to maternal and neonatal characteristics en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined the clinical and biological importance of thioredoxin-1, a redox-active defensive protein that controls multiple biological functions, in pregnant women. We measured serum concentrations of thioredoxin-1, total hydroperoxides, and redox potential in 60 pregnant women at the early third trimester: gestational age of 27-29 weeks. The thioredoxin-1 concentration (mean +/- SD) was 90 +/- 42 ng/ml. Total hydroperoxides was 471 +/- 105 U.CARR (1 U.CARR = 0.08 mg/dl H2O2). Redox potential was 2142 +/- 273 mu mol/l. The total hydroperoxides: redox potential ratio (oxidative stress index) was 0.23 +/- 0.08. Thioredoxin-1, total hydroperoxides, and oxidative stress index were higher and redox potential was lower than in blood of healthy adults. Total hydroperoxides and redox potential were mutually correlated significantly and negatively. Thioredoxin-1 correlated significantly and negatively and redox potential correlated significantly and positively with body weight and body mass index. Thioredoxin-1 and redox potential correlated significantly and positively with uric acid and albumin, respectively. Thioredoxin-1 and oxidative stress index correlated significantly and negatively and redox potential significantly and positively with neonatal birth weight. These results suggest that high concentrations of thioredoxin-1 are linked to high oxidative stress status in pregnant women and that neonatal birth weight is affected by the maternal oxidative condition during later pregnancy. en-copyright= kn-copyright= en-aut-name=NakatsukasaYoko en-aut-sei=Nakatsukasa en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TabuchiKazuhisa en-aut-sei=Tabuchi en-aut-mei=Kazuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TabuchiMasako en-aut-sei=Tabuchi en-aut-mei=Masako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MagamiTomoko en-aut-sei=Magami en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamadaMutsuko en-aut-sei=Yamada en-aut-mei=Mutsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiiYosuke en-aut-sei=Fujii en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YashiroMasato en-aut-sei=Yashiro en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsugeMitsuru en-aut-sei=Tsuge en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MorishimaTsuneo en-aut-sei=Morishima en-aut-mei=Tsuneo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Perineito Hahatokono Hosp Mothers & Children, Dept Pediat affil-num=2 en-affil= kn-affil=Okayama Univ, Dept Pediat, Grad Sch Med Dent & Pharmaceut Sci affil-num=3 en-affil= kn-affil=Perineito Hahatokono Hosp Mothers & Children, Dept Gynecol & Obstet affil-num=4 en-affil= kn-affil=Perineito Hahatokono Hosp Mothers & Children, Dept Gynecol & Obstet affil-num=5 en-affil= kn-affil=Perineito Hahatokono Hosp Mothers & Children, Dept Gynecol & Obstet affil-num=6 en-affil= kn-affil=Okayama Univ, Dept Pediat, Grad Sch Med Dent & Pharmaceut Sci affil-num=7 en-affil= kn-affil=Okayama Univ, Dept Pediat, Grad Sch Med Dent & Pharmaceut Sci affil-num=8 en-affil= kn-affil=Okayama Univ, Dept Pediat, Grad Sch Med Dent & Pharmaceut Sci affil-num=9 en-affil= kn-affil=Okayama Univ, Dept Pediat, Grad Sch Med Dent & Pharmaceut Sci affil-num=10 en-affil= kn-affil=Okayama Univ, Dept Pediat, Grad Sch Med Dent & Pharmaceut Sci en-keyword=later pregnancy kn-keyword=later pregnancy en-keyword=oxidative stress kn-keyword=oxidative stress en-keyword=redox potential kn-keyword=redox potential en-keyword=thioredoxin kn-keyword=thioredoxin en-keyword=total hydroperoxides kn-keyword=total hydroperoxides END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=2 article-no= start-page=219 end-page=226 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=200909 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Basic Study on Active Changes in Biological Function of Mouse Liver Graft in Cold Storage after Low-Dose X-Irradiation en-subtitle= kn-subtitle= en-abstract= kn-abstract=We previously reported that low-dose X-irradiation alleviates ischemia-reperfusion injury such as mouse paw edema. In this study, we examined active changes in the biological function of mouse liver grafts in cold storage after low-dose X-irradiation. Mouse livers were sham-irradiated or were irradiated with 0.25, 0.5, 1.0, or 5.0 Gy of X-ray and stored for 4, 8, 24, or 48 h in preservation or saline solution. The results show that storage for 24 h in saline solution after 0.5 Gy irradiation significantly increased the activity of superoxide dismutase (SOD) and catalase. Following storage for 4, 8, or 48 h in preservation solution, lipid peroxide levels of the 0.5 Gy irradiated group were significantly lower than those of the sham irradiated group. Following storage for 24 h in preservation solution, the activity of SOD and catalase of the 1.0 Gy irradiated group were significantly higher than those of the sham irradiated group. Hepatocytes stored in saline solution were vacuolated. However, no vacuole formation was observed in hepatocytes stored in preservation solution. These findings suggest that low-dose irradiation significantly activates antioxidative functions of liver grafts. Moreover, the dose at which enhancement of antioxidative function occurs in livers stored in preservation solution, which contains glutathione, is significantly higher than that in saline solution. en-copyright= kn-copyright= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshimotoMasaaki en-aut-sei=Yoshimoto en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakagawaShinya en-aut-sei=Nakagawa en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MizuguchiYuko en-aut-sei=Mizuguchi en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TaguchiTakehito en-aut-sei=Taguchi en-aut-mei=Takehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University affil-num=3 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University affil-num=4 en-affil= kn-affil=Radiation Safety Research Center, Central Research Institute of Electric Power Industry affil-num=5 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University affil-num=6 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University en-keyword=organ transplantation kn-keyword=organ transplantation en-keyword=low-dose irradiation kn-keyword=low-dose irradiation en-keyword=antioxidative function kn-keyword=antioxidative function en-keyword=hepatopathy kn-keyword=hepatopathy END start-ver=1.4 cd-journal=joma no-vol=43 cd-vols= no-issue=1 article-no= start-page=41 end-page=49 dt-received= dt-revised= dt-accepted= dt-pub-year=2008 dt-pub=200807 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=No Different Sensitivity in Terms of Whole-Body Irradiation between Normal and Acatalasemic Mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=To elucidate the radiosensitivity of an acatalasemic mouse, we examined the time and dose-dependency in the survival rates, the lymphocytes and the intestinal epithelial cells, and the antioxidant function after 3.0 to 12.0 Gy whole body irradiation. Results showed that no significant differences between acatalasemic mice and normal mice were observed in the survival rates and the histological changes in spleens and small intestine after each irradiation. The catalase activities in livers and spleens of acatalasemic mice were significantly lower than those of normal mice and the glutathione peroxidase activity in livers of acatalasemic mice was significantly higher than that of normal mice. At 10 days after 6.0 Gy irradiation, the catalase activities in livers of acatalasemic and normal mice and that in spleens of normal mice significantly decreased compared with no-irradiation control, and there were no differences between those catalase activities. The total glutathione content in acatalasemic mice was significantly higher than that in normal mice at 10 days after 6.0 Gy irradiation. These findings suggested that the radiosensitivity of acatalasemic mice in terms of whole body irradiation doesn’t significantly differ from that of normal mice, probably due to compensated sufficient contents of glutathione peroxidase and total glutathione in acatalasemic mice. en-copyright= kn-copyright= en-aut-name=NakagawaShinya en-aut-sei=Nakagawa en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MizuguchiYuko en-aut-sei=Mizuguchi en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshimotoMasaaki en-aut-sei=Yoshimoto en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakodaAkihiro en-aut-sei=Sakoda en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NomuraTakaharu en-aut-sei=Nomura en-aut-mei=Takaharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WangDa-Hong en-aut-sei=Wang en-aut-mei=Da-Hong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawabeAtsushi en-aut-sei=Kawabe en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TaguchiTakehito en-aut-sei=Taguchi en-aut-mei=Takehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University affil-num=2 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University affil-num=3 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University affil-num=4 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University affil-num=5 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University affil-num=6 en-affil= kn-affil=Radiation Safety Research Center, Central Research Institute of Electric Power Industry affil-num=7 en-affil= kn-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University affil-num=8 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University affil-num=9 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University affil-num=10 en-affil= kn-affil=Graduate School of Health Sciences, Okayama University en-keyword=acatalasemic mouse kn-keyword=acatalasemic mouse en-keyword=radiosensitivity kn-keyword=radiosensitivity en-keyword=catalase kn-keyword=catalase en-keyword=glutathione peroxidase kn-keyword=glutathione peroxidase en-keyword=total glutathione kn-keyword=total glutathione END
