Abstract |
本研究期間中にインジウム製造工場に勤務する作業者に健康調査を施行し, 影響の指標として肺拡散能(DLco)を測定した。測定値がQuality Grade A-Cの213名でDLco値の妥当性を検討後, 胸部CT所見の間質性変化, および気腫性変化スコアと比較した。相関係数(r)は, -0.320(気腫性変化とDLco), -0.412(気腫性変化と%DLco), -0.386(気腫性変化と%DLco/VA)とDLco, %DLco, %DLco/VAは間質性変化より気腫性変化のスコアとより相関が高かった。インジウム曝露者においてDLco値は, 胸部CT以外の気腫性変化の指標となる可能性が示唆された。
During the study period, we performed health checks on indium-exposed workers and measured diffuse lung capacity (DLco) as an effect marker of pulmonary function using a portable-type machine. After validity assessment of DLco with Quality Grade A-C (n=213), Spearman's correlation coefficient was conducted between DLCO and scores of emphysematous change or interstitial change on High-Resolution CT (HRCT) (n=48). Correlation coefficients (r) were -0.320 (emphysematous change and DLco), -0.412 (emphysematous change and %DLco) and -0.386 (emphysematous change and %DLco/VA). The correlation between emphysematous change on HRCT and %DLco was higher than that between interstitial change on HRCT and %DLco. Results suggested that DLco, %DLco and %DLco/VA in indium-exposed workers were effective markers for emphysema.
