1976年至1977年,某新生儿托儿所局部爆发了Ⅱ型轮状病毒感染。作者进行了脐血和母乳抗体在新生儿轮状病毒感染中的保护作用的研究。从1056个新生儿中收集了112个新生儿的脐血。根据电镜对新生儿粪便的观察,将脐血血清分成轮状病毒排毒儿组和无排毒儿组;根据喂养条件每组又分为母乳哺养和人工哺养两个小组。抗体滴度用酶标法
From 1976 to 1977, a type 2 rotavirus infection broke out locally in a neonatal nursery. The authors studied the protective effect of cord blood and human milk antibodies in neonatal rotavirus infection. Cord blood from 112 newborns was collected from 1056 newborns. According to the electron microscope observation of neonatal droppings, cord blood serum was divided into rotavirus detoxification group and no detoxification group. According to the feeding conditions, each group was further divided into two groups: breast feeding and artificial feeding. Antibody titer with enzyme labeling method
