对C57BL/6纯种小鼠注射同系、同种肿瘤细胞混悬液,二者脾细胞~3HTdR渗入指数(自发性增殖)早期皆增高。约10天后同种的减低,同系继续增高直至死亡前,表明同系的脾细胞晚期仍有较大活性,讨论了发生机理。这一方法可用于肿瘤的免疫药理学和肿瘤免疫发病机理的研究。 C57BL / 6 purebred mice injected with the same type, all kinds of tumor cell suspension, both spleen cells ~ 3HTdR infiltration index (spontaneous proliferation) were increased early. About 10 days after the reduction of the same species, the same series continued to increase until death, suggesting that the same line of splenocytes still have greater activity late, discuss the mechanism of occurrence. This method can be used for tumor immunopharmacology and tumor immune pathogenesis research.
