作者对疑诊为肺孢子虫肺炎患者142例中同时有经支气管活检标本的181份支气管冲洗液结果作了回顾性分析。方法为每次气管内滴注生理盐水约10ml,经过2～5次滴注收集约20ml的支气管冲洗液,加等量的50%乙醇后离心。每份离心所得标本制备6张涂片。涂片采用气雾剂喷雾固定,其中4张用Gill半氧化苏木精染色,2张用Gomori’s乌洛托品硝酸银染色。前一种染色常可显示 The authors retrospectively analyzed the results of 181 bronchial washings of 142 patients with suspected Pneumocystis pneumonia who had bronchial biopsy specimens at the same time. Methods for each tracheal instillation of saline about 10ml, after 2 to 5 drops of about 20ml bronchial fluid collection, plus an equal amount of 50% ethanol after centrifugation. Six samples were prepared for each centrifuge. The smears were aerosol sprayed, of which 4 were stained with Gill semi-oxidized hematoxylin and 2 were stained with Gomori’s methenamine silver nitrate. The former can often be displayed
