作者在20年中,根据①明确的接触发霉饲料后的发病史,②X 线片中见到肺部弥漫性病变;③查到对嗜热性放线菌中一种以上的抗体;收集了在临床上诊断为农民肺的病例60例的肺部病理检查材料。病理检查100%有由浆细胞、淋巴细胞组成,有时也有多形核白细胞或嗜酸细胞的间质性肺炎。70%有肉芽肿。2/3病人有间质纤维化,但都不太重。50%可以见到闭塞性细支气管炎。其他尚有未吸收肺炎、胸膜纤维化、泡沫细胞及异物。值得注意的是没有见到属于过敏反应Ⅲ型或 Arthus 反应的血管炎。作者捉到在间质性肺炎病理组织,用免疫荧
The author in 20 years, according to ① clear exposure to moldy feed after the onset of history, ② X-ray film to see diffuse lung disease; ③ found more than one thermophilic actinomycetes antibodies; collected in Clinical diagnosis of lung disease in 60 cases of lung pathological examination of materials. Pathological examination of 100% by plasma cells, lymphocytes, and sometimes also polymorphonuclear leukocytes or eosinophilic interstitial pneumonia. 70% have granulomas. 2/3 of patients have interstitial fibrosis, but not too heavy. 50% can see obliterative bronchiolitis. Others still did not absorb pneumonia, pleural fibrosis, foam cells and foreign bodies. It is noteworthy that vasculitis, which belongs to the allergic reaction type III or Arthus reaction, is not seen. The authors captured the pathology in interstitial pneumonia using immunofluorescence
