不饱和脂肪能降低人及动物的血清脂质,其胆固醇降低更明显,海产鱼类含不饱和脂肪较多,我们对马面鲀肝油的降血脂作用作了初步研究。正常大鼠组喂一般饲料:高脂组另加2%胆固醇、0.5%胆酸及10%猪油。空腹采血,应用 Wubenga 氏法测定血清总胆固醇。试验表明:(1)正常大鼠每天用马面鲀肝油灌胃一次(5ml/kg)共6天,血清总胆固醇下降为实验前的32.2%,P<0.001。(2)两组大鼠.一组喂高脂 Unsaturated fat can reduce the serum lipids of humans and animals, its cholesterol is reduced more significantly, and marine fishes contain more unsaturated fats. We have conducted a preliminary study on the lipid-lowering effect of horse chewing liver oil. The normal rat group was fed a general diet: the high-fat group was supplemented with 2% cholesterol, 0.5% cholic acid, and 10% lard. Fasting blood was collected and serum total cholesterol was measured by Wubenga’s method. The test showed that: (1) Normal rats were fed once daily with horse carp liver oil (5 ml/kg) for 6 days, serum total cholesterol decreased to 32.2% before the experiment, P<0.001. (2) Two groups of rats. One group fed high fat
