补体是血清中的正常球蛋白。补体系统含有11个血清蛋白质成分,各种成分在血清中含量不一,其中以补体 C_3含量最高,目前已能用免疫化学方法测定血清中 C_3含量。C_3分子量为185,000,主要在肝脏合成,电泳迁移率分析主要为β_1A 球蛋白。为探讨煤矽肺在发病中与补体的关系,我们测定了119例煤矿工人尘肺病患者及32 Complement is a normal globulin in serum. Complement system contains 11 serum protein components, various components in the serum content varies, including the highest level of complement C_3, has been able to use immunochemical methods for determination of serum C_3 content. C_3 molecular weight of 185,000, mainly in the liver synthesis, electrophoretic mobility shift analysis mainly β_1A globulin. To explore the relationship between silicosis and complement in the pathogenesis, we measured 119 coal miners pneumoconiosis patients and 32
