Of all patients with respiratory disease, 1778 (83.5%) patients had asthma and chronic obstructive pulmonary disease (COPD). 1. Of 1778 patients showing obstructive ventilatory dysfunction, 1311 (73. 7%) patients had asthma. The frequency of asthma in all patients with respiratory disease was 53.8% for the first 5 years from 1982, 71. 7% for the second 5 years, 73.6% for the third 5 years, 53.9% for the last 5 years and 43.6% in 2002. 2. The frequency of steroid -dependent intractable asthma (SDIA) was from 25.9% to 41. 3% except the frequency (68.4%) for the first 5 years. The frequency of patients with SDIA showed a tendency to decrease in recent years. The frequency of patients with pulmonary emphysema in those with COPD was very low 09.2% for the first 5 years) tended to increase and 76. 7% for the last 5 years and 88.5% in 2002. The frequency of patients over age 60 was 30. 1% for the first 5 years, and showed a tendency to increase, and 68.0% for the last 5 years and 85.4% in 2002. 3. The frequency of patients from distant areas outside Tottori prefecture was larger compared to the frequency inside Tottori prefecture. The number of patients from Okayama, Osaka, Hyogo, Tokyo, Ehime, Yamaguchi, and Kyoto was larger than the number from other distant areas. kn-abstract=1982年から2002年までの21年間の当医療センターで入院加療した2129例を対象に5年間毎にその年次推移を検討した．2129例のうちわけは，気管支喘息1311例（61.5％），COPD467例（21.9％），その他351例であった．1. 気管支喘息は，第1期（1982-1986年）の5年間では，平均11.4例/年であったが第4期（1997-2001年）では平均93例と初期と比べ8.1倍の増加が見られた．また，そのなかのSDIA （steroid-dependent intractable asthma）の頻度は初期の68.4％から第4期では28.9％にまで低下する傾向を示した．2. COPD症例は，初期の5年間（1982-1986年）では平均5.2例/年から第4期には45.4例へと8.7倍の増加が見られた．また，そのなかの肺気腫が占める割合いは初期の19.2％から第4期では78.5％と明らかな増加傾向を示した．なお，昨年度の1年間では，第4期の5年間（1997-2001年）とほぼ同様の傾向を示したが，全般的な傾向としては気管支喘息症例がやや減少し，一方肺気腫症例が増加する傾向が見られた．3. 気管支喘息およびCOPD症例の年齢別検討では，60歳以上の症例の頻度は第1期では30.1％だあったが，第4期では68.0％，そして昨年度は85.4％と，年々その頻度は高くなっていく傾向が見られた．すなわち，最近21年間の年次推移からは，温泉療法を必要とする呼吸器疾患患者が増加しつつあること，そしてその年令は年々高くなる傾向にあることが示された． en-copyright= kn-copyright= en-aut-name=TanizakiYoshiro en-aut-sei=Tanizaki en-aut-mei=Yoshiro kn-aut-name=谷崎勝朗 kn-aut-sei=谷崎 kn-aut-mei=勝朗 aut-affil-num=1 ORCID= en-aut-name=MitsunobuFumihiro en-aut-sei=Mitsunobu en-aut-mei=Fumihiro kn-aut-name=光延文裕 kn-aut-sei=光延 kn-aut-mei=文裕 aut-affil-num=2 ORCID= en-aut-name=HosakiYasuhiro en-aut-sei=Hosaki en-aut-mei=Yasuhiro kn-aut-name=保﨑泰弘 kn-aut-sei=保﨑 kn-aut-mei=泰弘 aut-affil-num=3 ORCID= en-aut-name=AshidaKozo en-aut-sei=Ashida en-aut-mei=Kozo kn-aut-name=芦田耕三 kn-aut-sei=芦田 kn-aut-mei=耕三 aut-affil-num=4 ORCID= en-aut-name=NishidaNorikazu en-aut-sei=Nishida en-aut-mei=Norikazu kn-aut-name=西田典数 kn-aut-sei=西田 kn-aut-mei=典数 aut-affil-num=5 ORCID= en-aut-name=TsugenoHirofumi en-aut-sei=Tsugeno en-aut-mei=Hirofumi kn-aut-name=柘野浩史 kn-aut-sei=柘野 kn-aut-mei=浩史 aut-affil-num=6 ORCID= en-aut-name=NagataTakuya en-aut-sei=Nagata en-aut-mei=Takuya kn-aut-name=永田拓也 kn-aut-sei=永田 kn-aut-mei=拓也 aut-affil-num=7 ORCID= en-aut-name=YokoiTadashi en-aut-sei=Yokoi en-aut-mei=Tadashi kn-aut-name=横井正 kn-aut-sei=横井 kn-aut-mei=正 aut-affil-num=8 ORCID= en-aut-name=TakataShingo en-aut-sei=Takata en-aut-mei=Shingo kn-aut-name=高田真吾 kn-aut-sei=高田 kn-aut-mei=真吾 aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=岡山大学三朝医療センター　内科 affil-num=2 en-affil= kn-affil=岡山大学三朝医療センター　内科 affil-num=3 en-affil= kn-affil=岡山大学三朝医療センター　内科 affil-num=4 en-affil= kn-affil=岡山大学三朝医療センター　内科 affil-num=5 en-affil= kn-affil=岡山大学三朝医療センター　内科 affil-num=6 en-affil= kn-affil=岡山大学三朝医療センター　内科 affil-num=7 en-affil= kn-affil=岡山大学三朝医療センター　内科 affil-num=8 en-affil= kn-affil=岡山大学三朝医療センター　リハビリテーション科 affil-num=9 en-affil= kn-affil=岡山大学三朝医療センター　内科 en-keyword=喘息 kn-keyword=喘息 en-keyword=COPD kn-keyword=COPD en-keyword=温泉療法 kn-keyword=温泉療法 en-keyword=高齢者 kn-keyword=高齢者 END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue= article-no= start-page=10 end-page=18 dt-received= dt-revised= dt-accepted= dt-pub-year=2003 dt-pub=20030201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=気管支喘息の low attenuation are (LAA) に対する長期喫煙の影響-4年間の経過観察- kn-title=Influence of long-term cigarette smoking on changes of lung density by high-resolution computed tomography in asthmatics--4 years follow-up study en-subtitle= kn-subtitle= en-abstract=気管支喘息患者の肺高分解能CT所見に対する長期喫煙の影響を検討することを目的とした｡非喫煙喘息患者8名,喫煙歴を有する喘息患者6名を対象として,肺機能,肺平均CT値(MLD),-950HU以下のlow attenuation area(RA(950))について4年間の経過観察を行った｡ 4年間の観察中,非喫煙喘息患者では努力肺活量,1秒量の低下を認めた｡喫煙歴を有する喘息患者では努力肺活量,1秒量,1秒率,肺拡散能 の低下および残気率の増加を認めた｡喫煙歴を有する喘息患者では吸気において,上肺野MLDの有意の低下,RA(950)の有意の上昇を認めたが,非喫煙喘息患者では有意の変化は認めなかった｡中肺RA(950)は喫煙歴を有する喘息患者,非喫煙喘息患者ともに有意の上昇を認めた｡また,呼気において,喫煙歴を有する喘息患者でMLDの有意の低下,RA(950)の有意の上昇を認めたが,非喫煙喘息患者では有意の変化は認めなかった｡喘息患者において,加齢は主に中肺野のlow atenuation area,喫煙は上肺野のlow atenuation areaに影響を及ぼすことが示唆された｡ kn-abstract=Background-The influence of cigarette smoking on the pathogenesis of asthma in the elderly remains controversial. This study attempts to estimate longitudinal changes in HRCT (high resolution computed tomography) parameters and pulmonary function parameters obtained for ex-smokers and never-smokers in asthmatics during 4-yr follow-up period. Methods-Fourteen asthmatics (6 ex-smokers and 8 never-smokers) were studied to determine the influence of aging and cigarette smoking on pulmonary function, and mean lung density (MLD) and the relative area of the lung showing attenuation values less than -950 HU (RA950) on HRCT scans. Results-The values of FVC and FEV1, were significantly more decreased in asthmatics without a smoking history during 4-yr follow-up period. The values of FVC, FEV1, FEV1/FVC and DLco/VA were significantly decreased and RV/TLC were significantly increased in asthmatics with a smoking history over 4 years, and annual decline in FEV1 ex-smokers was larger than that in never-smokers. In the upper lung field, inspiratory MLD was observed to shift in a negative direction and inspiratory RA950 was found to increase during 4-yr observation period in ex-smokers, but not in never-smokers. In the middle lung field, inspiratory RA950 was significantly enhanced in both two groups. Although expiratory MLD, expiratory RA950 and exp RA950/ins RA950 were observed to change significantly during the observation period in ex-smokers, no changes were observed in never-smokers. Conclusion-These results suggest that aging augments airspace enlargement predominantly in the middle lung field, while long term cigarette smoking further worsens emphysematous alterations in the upper lung field. en-copyright= kn-copyright= en-aut-name=MitsunobuFumihiro en-aut-sei=Mitsunobu en-aut-mei=Fumihiro kn-aut-name=光延文裕 kn-aut-sei=光延 kn-aut-mei=文裕 aut-affil-num=1 ORCID= en-aut-name=AshidaKozo en-aut-sei=Ashida en-aut-mei=Kozo kn-aut-name=芦田耕三 kn-aut-sei=芦田 kn-aut-mei=耕三 aut-affil-num=2 ORCID= en-aut-name=HosakiYasuhiro en-aut-sei=Hosaki en-aut-mei=Yasuhiro kn-aut-name=保﨑泰弘 kn-aut-sei=保﨑 kn-aut-mei=泰弘 aut-affil-num=3 ORCID= en-aut-name=TsugenoHirofumi en-aut-sei=Tsugeno en-aut-mei=Hirofumi kn-aut-name=柘野浩史 kn-aut-sei=柘野 kn-aut-mei=浩史 aut-affil-num=4 ORCID= 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=5 ORCID= en-aut-name=NishidaNorikazu en-aut-sei=Nishida en-aut-mei=Norikazu kn-aut-name=西田典数 kn-aut-sei=西田 kn-aut-mei=典数 aut-affil-num=6 ORCID= en-aut-name=NagataTakuya en-aut-sei=Nagata en-aut-mei=Takuya kn-aut-name=永田拓也 kn-aut-sei=永田 kn-aut-mei=拓也 aut-affil-num=7 ORCID= en-aut-name=TakataShingo en-aut-sei=Takata en-aut-mei=Shingo kn-aut-name=高田真吾 kn-aut-sei=高田 kn-aut-mei=真吾 aut-affil-num=8 ORCID= en-aut-name=YokoiTadashi en-aut-sei=Yokoi en-aut-mei=Tadashi kn-aut-name=横井正 kn-aut-sei=横井 kn-aut-mei=正 aut-affil-num=9 ORCID= en-aut-name=NakaiMutsuo en-aut-sei=Nakai en-aut-mei=Mutsuo kn-aut-name=中井睦郎 kn-aut-sei=中井 kn-aut-mei=睦郎 aut-affil-num=10 ORCID= en-aut-name=TanizakiYoshiro en-aut-sei=Tanizaki en-aut-mei=Yoshiro kn-aut-name=谷崎勝朗 kn-aut-sei=谷崎 kn-aut-mei=勝朗 aut-affil-num=11 ORCID= en-aut-name=TanimotoMitsune en-aut-sei=Tanimoto en-aut-mei=Mitsune kn-aut-name=谷本光音 kn-aut-sei=谷本 kn-aut-mei=光音 aut-affil-num=12 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部三朝医療センター　内科，放射線室 affil-num=2 en-affil= kn-affil=岡山大学医学部三朝医療センター　内科，放射線室 affil-num=3 en-affil= kn-affil=岡山大学医学部三朝医療センター　内科，放射線室 affil-num=4 en-affil= kn-affil=岡山大学医学部三朝医療センター　内科，放射線室 affil-num=5 en-affil= kn-affil=岡山大学医学部三朝医療センター　内科，放射線室 affil-num=6 en-affil= kn-affil=岡山大学医学部三朝医療センター　内科，放射線室 affil-num=7 en-affil= kn-affil=岡山大学医学部三朝医療センター　内科，放射線室 affil-num=8 en-affil= kn-affil=岡山大学医学部三朝医療センター　内科，放射線室 affil-num=9 en-affil= kn-affil=岡山大学医学部三朝医療センター　内科，放射線室 affil-num=10 en-affil= kn-affil=岡山大学医学部三朝医療センター　内科，放射線室 affil-num=11 en-affil= kn-affil=岡山大学医学部第二内科 affil-num=12 en-affil= kn-affil=岡山大学医学部第二内科 en-keyword=lung density kn-keyword=lung density en-keyword=high resolution computed tomography kn-keyword=high resolution computed tomography en-keyword=asthma kn-keyword=asthma END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue= article-no= start-page=19 end-page=24 dt-received= dt-revised= dt-accepted= dt-pub-year=2003 dt-pub=20030201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=高齢者喘息における HRCT 上の肺の low attenuation area (LAA) に及ぼす長期間喫煙の影響．肺気腫症例との比較． kn-title=Long-term cigarette smoking influences low attenuation area of the lungs on high-resolution CT in elderly patients with asthma, compared with pulmonary emphysema. en-subtitle= kn-subtitle= en-abstract=70歳以上の気管支喘息40例(20例喫煙者,20例非喫煙者)および肺気腫20例を対象に,長期間喫煙のHRCT上の-950 HU以下の肺のlow atenuation area(LAA)に及ぼす影響について検討した。 HRCT上の肺の% LAAは,喘息の喫煙例で非喫煙例に比べ有意に高い値を示した｡また,この% LAAは,肺気腫症例で喘息の喫煙例に比べさらに高い値を示した｡LAA比(呼気時LAA/吸気時LAA)は,職息症例では喫煙例で非喫煙例比べ有意に高い値を示したが,肺気腫症例ではさらに高い値を示した｡LAA比0.5以上を示す症例は,喘息の非喫煙例では見られず,喫煙例で20例中10例,肺気腫症例では全例に見られた｡そして,喘息喫煙例でLAA比が0.5以上を示す症例は,0.5以下の症例に比べ,% RVは有意に高く,また% DLcoは有意に低い値を示した｡しかし,% RV,% DLco値いずれも喘息のLAA比0.5以上の症例と肺気腫の間には有意差は見られず,喘息における喫煙の影響の高いことが示唆された｡ kn-abstract=The influence of cigarette smoking on the pathophysiology in elderly patients with asthma. Forty asthmatics over the age of 70 years (20 ex-smokers and 20 never-smokers), and 20 patients with pulmonary emphysema over age 70 (all ever-smokers) were studied to determine the influence of cigarette smoke on the low attenuation area (LAA) <-950 HU (RA950) of the lungs on high resolution CT (HRCT) scans, and the ratio of expiratory LAA to inspiratory LAA of the lungs in relation to pulmonary function. The LAA value was significantly higher in patients with pulmonary emphysema compared with ever-smokers of asthmatics. The LAA ratio was significantly higher in ever-smokers than in never-smokers of asthmatics, and the ratio was less than 0.5 in all never-smokers, and the ratio was more than 0.5 in 10 of 20 ever-smokers of asthmatics and in all patients with pulmonary emphysema. The % RV (residual volume) was significaltly larger and % DLco (diffusing capacity for carbon monoxide) was significantly lower in subjects with the ratio more than 0.5 than in those with the ratio less than 0.5. These results suggest that cigarette smoke influences LAA of the lungs in relation to % RV value and % DLco value. en-copyright= kn-copyright= en-aut-name=MitsunobuFumihiro en-aut-sei=Mitsunobu en-aut-mei=Fumihiro kn-aut-name=光延文裕 kn-aut-sei=光延 kn-aut-mei=文裕 aut-affil-num=1 ORCID= en-aut-name=HosakiYasuhiro en-aut-sei=Hosaki en-aut-mei=Yasuhiro kn-aut-name=保﨑泰弘 kn-aut-sei=保﨑 kn-aut-mei=泰弘 aut-affil-num=2 ORCID= en-aut-name=AshidaKozo en-aut-sei=Ashida en-aut-mei=Kozo kn-aut-name=芦田耕三 kn-aut-sei=芦田 kn-aut-mei=耕三 aut-affil-num=3 ORCID= en-aut-name=TsugenoHirofumi en-aut-sei=Tsugeno en-aut-mei=Hirofumi kn-aut-name=柘野浩史 kn-aut-sei=柘野 kn-aut-mei=浩史 aut-affil-num=4 ORCID= en-aut-name=NishidaNorikazu en-aut-sei=Nishida en-aut-mei=Norikazu kn-aut-name=西田典数 kn-aut-sei=西田 kn-aut-mei=典数 aut-affil-num=5 ORCID= en-aut-name=NagataTakuya en-aut-sei=Nagata en-aut-mei=Takuya kn-aut-name=永田拓也 kn-aut-sei=永田 kn-aut-mei=拓也 aut-affil-num=6 ORCID= en-aut-name=TakataShingo en-aut-sei=Takata en-aut-mei=Shingo kn-aut-name=高田真吾 kn-aut-sei=高田 kn-aut-mei=真吾 aut-affil-num=7 ORCID= en-aut-name=YokoiTadashi en-aut-sei=Yokoi en-aut-mei=Tadashi kn-aut-name=横井正 kn-aut-sei=横井 kn-aut-mei=正 aut-affil-num=8 ORCID= en-aut-name=TanizakiYoshiro en-aut-sei=Tanizaki en-aut-mei=Yoshiro kn-aut-name=谷崎勝朗 kn-aut-sei=谷崎 kn-aut-mei=勝朗 aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 affil-num=2 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　リハビリテーション科 affil-num=3 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 affil-num=4 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 affil-num=5 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 affil-num=6 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 affil-num=7 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 affil-num=8 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　リハビリテーション科 affil-num=9 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 en-keyword=cigarette smoking kn-keyword=cigarette smoking en-keyword=high resolution CT kn-keyword=high resolution CT en-keyword=% RV kn-keyword=% RV en-keyword=% DLco kn-keyword=% DLco en-keyword=elderly asthmatics kn-keyword=elderly asthmatics END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue= article-no= start-page=25 end-page=30 dt-received= dt-revised= dt-accepted= dt-pub-year=2003 dt-pub=20030201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=高齢者喘息における喫煙による気道過敏性の亢進について kn-title=An increase in bronchial hyperresponsiveness by cigarette smoking in elderly patients with asthma en-subtitle= kn-subtitle= en-abstract=高齢者喘息の病態におよぽす喫煙の影響についてはなお不明な点が多い｡本論文では,IgEにmediateされるアレルギー反応,気道過敏性,ロイコトリエンB4 (LTB4),C4(LTC4)産生に及ぼす喫煙の影響について,48例(20年以上の喫煙歴のある症例25例,非喫煙例23例)の70歳以上の高齢者喘息症例を対象に検討した｡ 1.吸入抗原に対する特異的IgE抗体の陽性頻度は,喫煙歴のある症例で,非喫煙例と比べ有意に高い値を示した｡ 2.メサコリンに対する気道過敏性の検討では,平均Cminは,喫煙例(949μg/ml)において非喫煙例(1677μg/ml)に比べ有意に低い値 を示し,喫煙例でより気道の過敏性が高いことが示された｡ 3.LTB4の産生は喫煙例で非喫煙例に比べ有意に高い傾向を示したが,LTC4に関しては両群間に有意の差は見られなかった｡以上の 結果より,長期間の喫煙は,IgEにmediateされるアレルギーやLTB4産生の亢進などを通じて気道過敏性を亢進させる可能性が示唆された｡ kn-abstract=Influence of cigarette smoking on the pathogenesis of asthma in the elderly remains controversial.

The LAA of the lungs on HRCT and the ratio of expiratory LAA (exp LAA) to inspiratory LAA (ins LAA) were also significantly larger in elderly asthmatics than in younger subjects. The generation of LTB4 and LTC4 was larger in younger patients than in elderly subjects, and LTB4 generation was significantly larger in younger subjects compared with elderly subjects. These results suggest that changes in IgE-mediated allergy, airflow and lung volume accompanied with hyperinflation are often observed in elderly asthmatics. en-copyright= kn-copyright=

The ventilatory parameters showing airflow limitation (% FEV(1) and FEV(1)%) were not significantly different between ever-smokers and never-smokers of elderly asthmatics. In contrast, % FEV(1) and FEV(1) % values were significantly lower in patients with pulmonary emphysema than in those with asthma with or without a history of smoking. The % RV value was significantly larger and % DLco value was significantly more decreased in ever-smokers compared with neversmokers of the elderly asthmatics. However, there were no significant differences in % RV and % DLco values between asthmatics with a history of smoking and patients with pulmonary emphysema.

In this study, the inluence of cigarette smoking on IgE - mediated allergy including the generation of leukotrienes B4 (LTB4) and C4 (LTC4) was examined in forty asthmatics over the age of 70 years (20 ex-smokers and 20 never-smokers), and 20 patients with pulmonary emphysema over age 70 (all ex - smokers). The frequency of patients with serum IgE more than 200 IU/ml was significantly larger in smoking asthmatics than in non - smoking asthmatics. The incidence of patients with positive RAST score for inhalant allergens, was also significantly higher in patients with a history of smoking than in those without a smoking history. There were no significant differences in the frequency of patients with positive RAST and those with serum IgE more than 200 IU/ml between non-smoking asthmatics and patients with pulmonary emphysema. The generation of leukotriene B4 (LTB4) by leukocytes was significantly more increased in ex-smokers than in never-smokers in the elderly asthmatics. The results suggest the possibility that cigarette smoking enhances IgE - mediated allergy in elderly patients with asthma. en-copyright= kn-copyright= en-aut-name=AshidaKozo en-aut-sei=Ashida en-aut-mei=Kozo kn-aut-name=芦田耕三 kn-aut-sei=芦田 kn-aut-mei=耕三 aut-affil-num=1 ORCID= en-aut-name=MitsunobuFumihiro en-aut-sei=Mitsunobu en-aut-mei=Fumihiro kn-aut-name=光延文裕 kn-aut-sei=光延 kn-aut-mei=文裕 aut-affil-num=2 ORCID= en-aut-name=HosakiYasuhiro en-aut-sei=Hosaki en-aut-mei=Yasuhiro kn-aut-name=保崎泰弘 kn-aut-sei=保崎 kn-aut-mei=泰弘 aut-affil-num=3 ORCID= en-aut-name=TsugenoHirofumi en-aut-sei=Tsugeno en-aut-mei=Hirofumi kn-aut-name=柘野浩史 kn-aut-sei=柘野 kn-aut-mei=浩史 aut-affil-num=4 ORCID= en-aut-name=NishidaNorikazu en-aut-sei=Nishida en-aut-mei=Norikazu kn-aut-name=西田典数 kn-aut-sei=西田 kn-aut-mei=典数 aut-affil-num=5 ORCID= en-aut-name=NagataTakuya en-aut-sei=Nagata en-aut-mei=Takuya kn-aut-name=永田拓也 kn-aut-sei=永田 kn-aut-mei=拓也 aut-affil-num=6 ORCID= en-aut-name=TakataShingo en-aut-sei=Takata en-aut-mei=Shingo kn-aut-name=高田真吾 kn-aut-sei=高田 kn-aut-mei=真吾 aut-affil-num=7 ORCID= en-aut-name=YokoiTadashi en-aut-sei=Yokoi en-aut-mei=Tadashi kn-aut-name=横井正 kn-aut-sei=横井 kn-aut-mei=正 aut-affil-num=8 ORCID= en-aut-name=TanizakiYoshiro en-aut-sei=Tanizaki en-aut-mei=Yoshiro kn-aut-name=谷崎勝朗 kn-aut-sei=谷崎 kn-aut-mei=勝朗 aut-affil-num=9 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 affil-num=2 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 affil-num=3 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　リハビリテーション科 affil-num=4 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 affil-num=5 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 affil-num=6 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 affil-num=7 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 affil-num=8 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　リハビリテーション科 affil-num=9 en-affil= kn-affil=岡山大学医学部附属病院三朝医療センター　内科 en-keyword=cigarette smoking kn-keyword=cigarette smoking en-keyword=IgE - mediated allergy kn-keyword=IgE - mediated allergy en-keyword=LTB4 kn-keyword=LTB4 en-keyword=LTC4 generation kn-keyword=LTC4 generation en-keyword=elderly asthmatics kn-keyword=elderly asthmatics END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue= article-no= start-page=55 end-page=63 dt-received= dt-revised= dt-accepted= dt-pub-year=2003 dt-pub=20030201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=気管支喘息に対する温泉療法とα-リノレン酸強化食の効果 kn-title=Effects of spa therapy combined with dietary supplementation with alpha -linolenic acids on bronchial asthma en-subtitle= kn-subtitle= en-abstract=N-3系脂肪酸は喘息に有効であることが報告されている｡また喘息に対する温泉療法の有効性も報告されている｡今回我々は温泉療法とn-3系脂肪酸を多く含むエゴマ油食の喘息に対する効果を検討した｡14名の喘息患者に温泉療法及びα-リノレン酸(n-3系)を多く含むエゴマ油食の摂取を8週間行い,その間の白血球ロイコトリエンC 4(LTC4)の産生能と呼吸機能の変化を検討した｡ その結果白血球LTC4の産生能は治療開始2過後より4,8過後と抑制された(P<0.05)Oピークフロー値(PEF)は治療2,4,6,8週後に有意な増加がみられた(P<0.05)｡また呼吸機能[努力肺活量(FVC),1秒量(FEV(1)),FEF(25),FEF(75),FEF(25-75)]は治療開始4過,8過後に有意に改善した(P<0.05)｡これらの結果より温泉療法とエゴマ油食は白血球LTC4の産生能を抑制することにより,呼吸機能を改善させ,気管支喘息の治療に有効であることが示唆された｡ kn-abstract=N-3 fatty acids are reportedly effective for asthma.
