人乳不但热量高,所含的蛋白质、脂肪、碳水化合物容易消化吸收,还含有大量的抗体。人工喂养的婴儿,得不到母乳中所特有的免疫成分,因此,感染的发病率及死之率比母乳喂养的婴儿高。本组检测了181份母乳中JgG、IgA、IgM 和补体 C_3的含量,还测定了母乳喂养婴儿的体液免疫、细胞免疫及补体C_3含量,并与人工喂养婴儿进行比较,对母乳喂养和人工喂养婴儿的免疫功能进行探讨。 Human milk is not only high in calories, containing protein, fat, carbohydrates easily digested and absorbed, but also contains a large number of antibodies. Artificially fed infants, who are not immune to the specific components of breast milk, have a higher rate of morbidity and mortality compared with breastfeeding infants. In this study, we detected the contents of JgG, IgA, IgM and complement C_3 in 181 breast milk samples. The humoral immunity, cellular immunity and complement C_3 content in breastfeeding infants were also measured. Compared with those of artificial feeding infants, breastfeeding and artificial feeding Infants’ immune function is explored.
