本研究旨在检查由不同脂肪酸组成的多种脂肪对大鼠喂以过量β-胡萝卜素时对肝与血浆中β-胡萝卜素水平的影响,同时也研究过量维生素E摄入对组织β-胡萝卜素与维生素A水平的影响。实验动物选用雄性断奶Wistar Kgoto系大鼠,随机分为5组(8只大鼠/组),并自由摄食如下含不同膳食脂肪的β-胡萝卜素补充饲料:Ⅰ组 8％可可油(饱和脂肪)+2％红花油(富含ω-6脂肪酸的多不饱和脂肪);Ⅱ组 8％橄榄油(单不饱和脂肪)+2％红花油;Ⅲ组10％红花油;Ⅳ组10％红花油+0.2％DL-α-生育酚乙酸酯;Ⅴ组8％步鱼油(富含ω-3脂肪 The aim of this study was to examine the effect of various fatty acids composed of different fatty acids on β-carotene levels in the liver and plasma when fed excess β-carotene in rats and to investigate the effect of excess vitamin E intake on tissue β-carrot Effects of vitamin A and vitamin A levels. Male Wistar Kgoto rats were randomly divided into 5 groups (8 rats / group) and fed the following diet supplemented with β-carotene with different dietary fat: group Ⅰ 8% cocoa butter (saturated fat ) + 2% safflower oil (polyunsaturated fats rich in ω-6 fatty acids); Group Ⅱ 8% olive oil (monounsaturated fat) + 2% safflower oil; Group Ⅲ 10% safflower oil; Group Ⅳ 10% safflower oil + 0.2% DL-α-tocopherol acetate; Group V 8% step fish oil (rich in omega-3 fats
