摘要
本实验给雌性断乳大鼠分别喂以含和不含１％胆固醇的饲料，并比较了大豆蛋白和酪蛋白对大鼠血浆和肝脏胆固醇含量的影响。结果表明，当饲料中无胆固醇时，酪蛋白可增加大鼠肝脏胆固醇含量。含１％胆固醇的饲料也可明显升高酪蛋白组大鼠肝胆固醇含量。而大鼠血浆胆固醇含量不受食物蛋白质来源的影响。胆汁中胆固醇含量与饲料中胆固醇水平高低有关，而与蛋白质来源无关。结果提示：大豆蛋白质能够降低动物肝胆固醇含量。
he effects of dietary soybean protein and casein on
plasma and li-ver cholesterol concentration were evaluated in female
rats fed with di一ets with or without 1% cholesterol.After consuming
the diet free fromcholestetol casein produced higher liver
cholesterol level than soybeanprotein did.Incorporation of
cholesterol into diet further increasedliver cholesterol
concentration in rats fed with casein.The amountof cholesterol in the
diets,but not the type of dietary protein influe-nced the biliary
cholesterol content.The present study demonstrates that sovbean
protein decreases the liver cholesterol concentrations inthe female
rats.
