11、 the corresponding C diets. The humoral immune response of mice fed C, S, and W diets was substantially lower than that of mice fed stock diet, whereas that of mice fed L diet was higher. The above-described immune effect of all tested proteins was obtained at 20 g/100 g concentration with no furthe

Little difference in immune responses was noted among mice fed C, S or W protein diets. The principal factor responsible for the
13、 observed immune effect does not appear to be the availability or concentration of single essential amino acids but rather the composite effect of the specific amino acid distribution in the protein.研究主题服用美源康富ABD活性因子对小鼠免疫系统的影响研究内容选用C3H/HeN小鼠,分别喂食含20%乳白蛋白、酪蛋白、大豆蛋白和小麦蛋白饲料和普通饲料,检测小鼠对羊血红细胞和马血红细胞的特 定免疫反应

19、he humoral response of all mice fed the L diet was found to be higher than that of mice fed the C diet or non purified diet.
