【Abstract】 Lung biopsies of ten grain workers with stage I pneumoconiosis were observed. The main histopathological changes were diffuse pulmonary fibrosis and deposition of large amount of dust. Fibro-cellular nodules were seen in three cases. Fibrosis of small airways and hyaline degeneration of small vessels were seen obviously in some cases. Grain dust had been analysed. It consisted of 58% organic and 42% inorganic dust, which contained 3.66-16.7% free silica. It is considered that both of organic and inorganic dust induce pulmonary pathological changes of the grain workers in cooperation.更多还原
