“农民肺”(Farmmer’s Lung)是由于吸入霉变的稻草或植物粉尘中含有普通嗜热性放线菌或凡尼微小多孢子菌而致的肺部疾病,其临床表现特点主要是支气管与肺周围部分的反应性病变所引起,并可导致气体交换障碍。Madsen 1976年报告英国一些地区农民肺的发病率达2.3～8.6%。Gruchow 等1981年也称,Wisconsin 地区农民中沉淀素反应阳性者达6%。说明农民肺在西方是个较常见的疾病;在东方,日本曾多次报道这类病例。在我国,特别是江南以生产稻米为主的地区,气候温湿,应有农民肺存在,只是由于诊断手段不全而漏 Farmmer’s Lung is a lung disease caused by inhalation of mildewed straw or plant dust containing common thermophilic actinomycetes or Microsporum perenne, and its clinical manifestations are mainly bronchial and pulmonary Reactive lesions in surrounding areas cause gas barrier disorders. Madsen reported in 1976 that the incidence of lung disease in some areas of Britain was 2.3 to 8.6%. Gruchow et al. (1981) also said that 6% of precipitin-positive peasants in the Wisconsin area were positive. This shows that farmer lungs are a common disease in the West. In the East, Japan has repeatedly reported such cases. In our country, especially in the areas where rice is mainly produced in the southern part of the Yangtze River, there should be peasant lungs in the warm and humid climate, only because of incomplete diagnosis and omission
