作者设想用皮内注射自身白细胞来分析矿工、矽肺和矽肺患者体内免疫过程状况。观察了45名矿工(无矽肺)、55名Ⅰ期矽肺和22名矽肺结核患者。在被观察对象的左前臂曲肌处,皮内注射0.2毫升的自身白细胞混合液(每毫升含10～20万白细胞),另注射0.2毫升肝素生理溶液作 The authors envision using intradermal injection of their own leukocytes to analyze the immune status of the miners, silicosis and silicosis patients. Forty-five miners (silicosis-free), 55 stage I silicosis and 22 silicosis patients were observed. In the left forearm muscle of the observed object, intradermal injection of 0.2 ml of leukocyte mixture (each containing 10 to 200,000 leukocytes), the other injection of 0.2 ml of heparin physiological solution
