人工喂养婴得不到母乳中所特有的免疫成份,他们的发病率及死亡率比母乳喂养婴明显增高。这引起不少学者的重视,对母乳的免疫功能作了大量的研究,并呼吁恢复母乳喂养。为引起国内妇幼工作者的重视,作者综述了近年来有关人乳的抗细菌、病毒感染作用的研究成果。尽管人乳中的免疫因素是多方面的,而且大部份的研究是在体外进行,但可推论,其中某些因素在婴儿体内可同样起作用的。两岐乳杆菌生长因子(Growth facotr of lactobacillus bifidus) 早在二十世纪初已经认识到两岐乳杆菌能在母乳喂养的新生儿肠道中迅速生长,而人工喂养的婴儿则产生混合肠道菌丛。这是由于人 Artificial-feeding babies do not have the specific immune components found in breast milk, and their morbidity and mortality are significantly higher than those of breast-fed babies. This has attracted the attention of many scholars, made a lot of research on the immune function of breast milk, and called for the resumption of breastfeeding. In order to arouse the attention of domestic women and children workers, the author summarizes the research results on the anti-bacterial and viral infection of human milk in recent years. Although the immunological factors in human milk are manifold and most studies are conducted in vitro, it can be inferred that some of these factors may play a role in infancy. As early as the early twentieth century, Growth facotr of lactobacillus bifidus recognized the rapid growth of L. bifidum in the breast-fed neonates’ intestines, whereas artificially fed infants developed mixed gut flora .
