| Outline of Final Research Achievements |
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.
