将所采集的含药血清分为２份，其中１份经５６℃３０ｍｉｎ灭活，对比灭活前后血清对病毒致细胞病变作用的影响，结果：正常血清灭活后相对作用强度平均降低５０％左右，抑制病毒致细胞病变的作用基本消失；１次给药采集的含药血清灭活后相对作用强度平均降低５０％左右，２次给药采集的含药血清灭活后相对作用强度平均降低３５％左右，但两者灭活前所表现的有效时间点均仍然存在。 The collected drug-containing serum was divided into 2 parts, 1 of which was inactivated at 56° C. for 30 min, and the effect of serum before and after inactivation on the virus-induced cytopathic effect was compared. As a result, the relative intensities of normal serum inactivation were reduced by an average of 50%. Left and right, the effect of inhibition of cytopathic effect caused by virus disappeared; the relative intensities of inactivated drug-containing serum collected after one administration were reduced by an average of 50%, and the relative intensities of inactivated drug-containing serum collected after two administrations were reduced. About 35%, but the effective time points before the inactivation of the two still exist.
