血清对异种细胞(正常细胞和癌细胞)的损伤效应与血清供体和靶细胞之间的亲缘关系有关,它们之间的亲缘关系越远,损伤效应的活性越高。自体保温条件较差的动物,其血清对异种细胞的损伤效应活性受其所处环境中的气温变化的影响,气温高时损伤效应的活性高,气温下降时损仿效应的活性也随之下降。肿瘤的存在并不影响其宿主血清对异种细胞的损伤效应。血清对异种细胞的损伤效应与抗体无关。 Serum damage to xenogenic cells (normal cells and cancer cells) is related to the relationship between serum donor and target cells. The farther their relationship is, the higher the damage activity is. The animals whose autologous thermal insulation is poor have the effect of the damage effect of the serum on the xenogeneic cells affected by the change of the temperature in the environment where the serum is located, and the activity of the damage effect is high when the temperature is high, and the activity of the loss-like effect decreases when the temperature is decreased . The presence of the tumor does not affect the damage effects of its host serum on xenogeneic cells. The effect of serum on xenogeneic cells has nothing to do with antibodies.
