为了深入研究母乳喂养与牛乳喂养的新生儿唾液及粪便中SIgA含量的情况,探索母乳的免疫价值,我科应用放射免疫(双抗体-PEG法)对牛乳喂养和喂过母乳初乳的早期新生儿唾液和粪便进行SIgA测定。现报告如下。一、对象及标本留取测定对象为健康新生儿,第1组至少一天晡过二次母乳者(白天喂母乳,夜间喂牛乳);第2组完全为牛乳喂养者,均留取3～7天唾液及粪便标本;第3组未开奶或仅给予少量葡萄糖水的新生儿,测其胎粪。 In order to further study the content of SIgA in saliva and feces of breast-fed and milk-fed neonates and to explore the immunological value of breast milk, our department applied radioimmunoassay (double-antibody-PEG method) to milk infants and early neonates fed colostrum Saliva and faecal SIgA determination. The report is as follows. First, the object and specimens were taken for the determination of healthy newborns, group 1 at least one day 晡 over two breastfeeding (breastfeeding during the day, milk at night); the second group was completely breastfeeding, were taken 3 to 7 Day saliva and stool samples; the first three groups were not given milk or only a small amount of glucose in newborns, measuring their meconium.
