铅是环境中最常见的毒物之一。近年来的研究表明，铅可能是一种潜在性的免疫抑制因子[1]。并将重点从职业性铅暴露转向长期低水平铅暴露。有文献报道，长期低铅染毒可影响大鼠的红细胞免疫功能[2]。但有关长期低铅暴露对机体红细胞免疫功能影响的研究少见报道。本文采用补体致? Lead is one of the most common toxicants in the environment. In recent years, studies have shown that lead may be a potential immunosuppressive factor [1]. And shifted the focus from occupational lead exposure to long-term low levels of lead exposure. It has been reported in the literature that long-term low-lead exposure can affect rat erythrocyte immune function [2]. However, few studies have reported the effect of long-term low-lead exposure on the immune function of the body’s red blood cells. In this paper, caused by complement?
