本文对40名产妇从产后第1天到6个月,收集其母乳进行溶菌酶含量的动态观察。结果:产后第1天的初乳中溶菌酶含量最高(944.2±335.3μg/ml),是牛奶中溶菌酶含量的429倍;半个月时降至最低点;1个月后母乳中溶菌酶含量又逐渐升高。但产妇血清中溶菌酶的含量低,而且无明显变化。母乳加热62.5℃30分钟,溶菌酶活性损失8.3％,SIgA损失29.7％,巴斯德灭菌法同样适合奶库中贮存人乳的消毒。 In this paper, 40 mothers from the first postpartum to 6 months, the collection of breast milk lysozyme dynamic observation. Results: The content of lysozyme in the colostrum on day 1 postpartum was the highest (944.2 ± 335.3μg / ml), which was 429 times that of lysozyme in milk; it dropped to the lowest point at half a month; after one month, the lysozyme The content is gradually increased. However, maternal serum lysozyme content is low, but no significant change. Breast milk heated 62.5 ℃ for 30 minutes, loss of lysozyme activity of 8.3%, SIgA loss of 29.7%, Pasteur sterilization method is also suitable for storage of human milk in the milk warehouse disinfection.
