ABSTRACT

Of all types of farm work in Japan, the threshing of rice, in which dust is generated in large quantities, produces the worst influence on the respiratory organ, and the author termed this symptom “thresher's bronchitis.” The repetition of thresher's bronchitis gives rise to chronic bronchitis. There have been the autposy cases of elderly farmers who suffered from pneumoconiosis, as he had been exposed to dustin over 30 years of threshing work. The symptom might well be called “thresher's pneumoconiosis.”
