Objectives: Recently, attention has been paid to the impact of cigarette smoking on skeletal muscles, as its underlying pathophysiological mechanism has been gradually elucidated. In this study, we aimed to examine whether cigarette smoking is associated with muscle mass reduction and low muscle strength in elderly men.Methods: The study participants comprised 417 community-dwelling elderly men (aged 73±6 years) without severe glucose intolerance, chronic kidney disease, or liver disease. Bioelectrical impedance analysis was performed to estimate appendicular skeletal muscle mass (ASM), which was normalized for height (ASM index, kg/m2). Handgrip strength (HGS) was measured using a Smedley grip dynamometer. Cumulative smoking exposure level during a lifetime was expressed in pack-years, which is a product of the average number of packs of cigarettes smoked per day and smoking duration in years.Results: When the participants were stratified on the basis of cumulative smoking exposure (<10 pack-years, 10–39 pack-years, ≥40 pack-years), the ASM index and HGS progressively decreased with increasing exposure level (P for trend <0.01). In multiple regression analysis, heavy smoking (defined as ≥40 pack-years) was found to be a significant determinant of the ASM index and HGS, independent of potential confounding factors. Among former smokers, the subgroup that quit smoking for ≥20 years had a significantly higher ASM index and HGS than the subgroup that quit smoking for <10 years. The duration of smoking cessation was significantly associated with the ASM index and HGS, even after adjusting for cumulative smoking exposure.Conclusions: These findings suggest that cigarette smoking contributes to the loss of muscle mass and function in elderly men and that smoking cessation could reverse the impact of cigarette smoking on skeletal muscles.

本研究の目的は炭酸ガス入り足浴(;炭酸ガス浴)の有用性の検討である。健康な女性16人(平均年齢19.6±0.7歳,平均身長160.2±5.0cm,平均体重52.4±5.8kg)を対象とし炭酸ガス浴と従来の足浴(;混浴)を実施した。測定内容は生理的指標として,皮膚血流量,体温(中枢温・末梢温・・腋窩温),脈拍,血圧であり,主観的指標として炭酸ガス浴と温浴を比較した被験者の感想である。生理的指標は足浴前,足浴直後,15分後,30分後,1時間後,2時間後に測定した。データの分析はpaired-t検定を行った。その結果,炭酸ガス浴後の皮膚血流量において,温浴と比較して有意に上昇していた(p<0.01〜O.05)。体温,脈拍,血圧では有意な差はみとめなかった。被験者の感想では,炭酸ガス浴の満足度は非常に高かった。以上のことから,炭酸ガス浴は皮膚血流量増加による保温効果や心地よさのレベルを高めることが明らかとなった。
