摘要
本文对不同时期母乳及与母初乳相配对的母血中肿瘤坏死因子-α(TNFα)的测定,发现母血中TNFα与母初乳中TNFα无相关关系,揭示了母乳中TNFα不是从母血中TNFα简单扩散而来。而对不同时期母乳中TNFα测定,显示都有一定量的TNFα存在,同时也具有生物活性。若及早通过母乳喂养,受体婴儿可获得一定量的TNFα,起到抗感染及免疫调节的作用。
This study have measured TNFα of breast milk in different times and of women blood corresponded to breast milk in postnatal. It was found that TNF?α in breast milk was no correlation with that in postnatal women blood and showed that TNF α in breast milk is not diffused from TNFα of women blood in different times, while assaying TNFα of breast milk of breast milk in diferent times. It was suggested that breast milk exists not only TNFα,but also biological activity. If feeding breast milk early,Infant will gain .a little TNFα and play a role in antimicroorganism and iimmunoregulation.
