作者报道了淋巴因子、短小棒状杆菌(Corynebactrium parvum)以及结核杆菌H_(87)Ra激活的C57BL/6鼠腹腔巨噬细胞,在体外对EMT6肿瘤细胞都有细胞毒作用,但不能杀死杜氏利什曼原虫苏丹株IS无鞭毛体(Leishmania donovani Sudan Strain IS),只有在感染无鞭毛体后每天向巨噬细胞加淋巴因子,使持续地维持在激活状态,才能清除无鞭毛体。实验用无鞭毛体,是在叙利亚金黄色田鼠腹腔注射受染脾脏匀浆,两个月后, The authors reported that lymphocytes, Corynebactrium parvum, and C57BL / 6 murine peritoneal macrophages activated by Mycobacterium tuberculosis H_ (87) Ra have cytotoxic effects on EMT6 tumor cells in vitro but not Dussrat In the case of Leishmania donovani Sudan Strain IS, the zymograms of Sudan Strain IS, removal of the amastigotes can only be achieved by adding lymphokines to macrophages daily after persistence of the activated state. Experiment with amastigotes, is Syrian golden vole intraperitoneal injection of infected spleen homogenate, two months later,
