Laskowski等(1951)证明人和牛的初乳中有胰蛋白酶抑制剂。后来分离出牛初乳胰蛋白酶抑制剂,并作了定性分析。还发现了同类抑制剂(isoinhibi-tor)。这些抑制剂在猪和鼠的初乳中也存在。关于人乳的胰蛋白酶抑制剂的研究尚少。在不同的哺乳期,人乳中蛋白酶抑制剂的存在、含量及其特性的资料也不完全,其生理作用也不清楚。本文作者报告了从出生前到分娩后4个月期间,人乳中某些蛋白酶抑制剂的存在、含量及电泳特性(分娩后不同时期人乳蛋白酶抑制活性情况见
Laskowski et al. (1951) demonstrated that trypsin inhibitors are present in human and cow colostrums. Later isolated colostrums trypsin inhibitor, and made a qualitative analysis. Also found isohhibitor. These inhibitors are also present in colostrums of pigs and mice. There is little research on human milk trypsin inhibitor. In different lactation, human milk protease inhibitor presence, content and characteristics of the information is not complete, its physiological role is not clear. The authors report the presence, content and electrophoretic properties of certain protease inhibitors in human milk from prenatal to postnatal period of 4 months (human milk protease inhibitory activity at different stages of delivery
