本文对四例尘肺的尸体解剖材料进行了病理组织学的研究。其中一例是典型的矽肺,一例是典型的石棉肺,另两例是非典型的矽肺。此外,还对一些鼠进行了胸膜腔内单独注入矽,尘混悬液的病理实验研究。本文着重地研究了肺纤维化的组织发生情况。本例典型的矽肺患者表现肺间质的纤维化和显著的支气管淋巴结的纤维化,并有大量矽结晶的沉着;而本例典型的石棉肺呈现肺泡内型的纤维化,没有明显的局部淋巴结的肿大,也没有石棉的沉着。两
In this paper, four cases of pneumoconiosis were studied by histopathology. One of the cases is typical silicosis, one case of a typical asbestosis lung and the other two cases of atypical silicosis. In addition, a number of mice were also injected into the pleural cavity of silicon, dust suspension pathological experimental study. This article focuses on the occurrence of pulmonary fibrosis. In this case, a typical silicosis patient showed fibrosis of the lung interstitium and significant fibrosis of the bronchial lymph nodes with a large number of crystalline deposits of silica; in this case, the typical asbestosis of the lung presented with alveolar endogenous fibrosis with no apparent local lymph nodes Swollen, no asbestos calm.
