农民在从事农业生产劳动过程中,若吸入含有嗜热放线菌的霉变稻谷粉尘,可以发生过敏性肺泡炎,即“农民肺”。慢性农民肺可合并肺间质纤维化和肺心病。1981年同济医科大学在我县发现慢性农民肺死亡病例和现症病人后,我院又收治5例急性农民肺病人,报道如下。 一、病史、症状及体征 5例中男4人,女1人。年龄35～55岁,平均38.4岁。呼吸道病史8～32年。平均21年。有明显接触霉稻草发病和复发病史者2例。 发病时均有不同程度的畏寒、发热、咳嗽、气急、乏力。2例伴有哮喘,4例咳少量白色痰,2例痰中带血丝。患者均于发病后2～7天,因咳嗽、气急住院。 5例有低热(37～37.5℃),呼吸急促,平均27次/分。3例有明显的三凹征和紫绀。2例胸廓 Farmers engaged in agricultural production process, if the inhalation of mildew containing thermophilic actinomycetes rice dust, allergic alveolitis, or “farmer lungs.” Chronic peasant lung may be associated with pulmonary fibrosis and pulmonary heart disease. 1981 Tongji Medical University in our county found that chronic lung disease deaths and cases of patients, our hospital has treated 5 cases of acute peasant lung disease, reported as follows. First, history, symptoms and signs in 5 cases, 4 males and 1 females. Aged 35 to 55 years old, with an average of 38.4 years old. Respiratory history of 8 to 32 years. Average 21 years. There are two cases of obvious contact with mold straw pathogenesis and relapse. When the onset of varying degrees of chills, fever, cough, shortness of breath, fatigue. 2 cases with asthma, 4 cases of cough with a small amount of white sputum, 2 cases with bloody sputum. Patients were 2 to 7 days after onset, due to cough, urgency hospitalization. 5 patients had low fever (37 ~ 37.5 ℃), shortness of breath, an average of 27 beats / min. 3 cases have obvious three concave signs and cyanosis. 2 cases of thoracic
