将接种结核菌苗(BCG)或感染夏氏疟原虫的小鼠脾细胞,加相应抗原在37℃培养48小时后取上清液,观察此上清液对巨噬细胞吞噬IgG致敏的红细胞和吞噬感染伯氏疟原虫和夏氏疟原虫红细胞的活化作用。将存留于腹腔的巨噬细胞在体外与脾细胞因子孵育,然后测定巨噬细胞摄入IgG致敏的红细胞或感染疟原虫红细胞的数目。与对照组相 Spleen cells of mice inoculated with tuberculosis bacilli (BCG) or infected with P. pastoris were incubated with the corresponding antigens for 48 hours at 37 ° C, supernatants were observed, and the supernatant was observed for macrophage phagocytosis of IgG-sensitized erythrocytes And phagocytosis of Plasmodium berghei and Plasmodium malariae erythrocytes. Macrophages remaining in the peritoneal cavity were incubated with splenic cytokines in vitro and the number of erythrocytes or plasmodium-infected erythrocytes infected with IgG by macrophages was determined. Compared with the control group
