5种植物油对大鼠血脂和脂质过氧化的影响

观察 5种植物油在高脂血症形成过程中对大鼠血脂和脂质过氧化的影响。在高脂饲料中分别加入6 %的猪油、松籽油、紫苏油、黑加仑油、琉璃苣油和月见草油喂饲 Wistar雄性成年大鼠 3周 ,5种植物油组大鼠血清甘油三酯 (TG)、总胆固醇 (TC)、低密度脂蛋白胆固醇 (L DL- C)、L DL- C与高密度脂蛋白胆固醇(HDL - C)比值 (L DL - C/ HDL - C)的增加值和 HDL - C/ TC、卵磷脂胆固醇酰基转移酶 (L CAT)活性的下降均不同程度地低于单纯食猪油的高脂对照组。紫苏油、黑加仑油、琉璃苣油和月见草油可提高血清 HDL- C、高密度脂蛋白亚组分 胆固醇 (HDL2 - C)及 HDL2 - C与高密度脂蛋白亚组分 胆固醇 (HDL3- C)比值 (HDL2 - C/ HDL3- C)。紫苏油、黑加仑油和月见草油组大鼠肝脏过氧化脂质 (L PO)含量高于松籽油、琉璃苣油和猪油组。结果表明 5种植物油均具有一定的调节血脂作用 ,松籽油和琉璃苣油的组织脂质过氧化物相对较低

Effect of five kinds of vegetable seed oil on serum lipid and lipid peroxidation in rats

The effects of vegetable seed oil on hyperlipidemia induced by high lipid diet in rats. Male adult Wistar rats were fed on the test diet containing 94% high lipid diet and 6% lard pinon seed oil, perilla seed oil, blackcurrent seed oil, borage seed oil and evening primrose seed oil respectively for 3 weeks. The results showed that the vale of trilyceride(TG), total cholesterol(TC),low density lipoprotein cholesterol(LDL C), LDL C/HDL C(high density lipoprotein cholesterol)ratio increased and the vale of HDL C/TC ratio and lecithin cholesterol acyltransferase(LCAT)activity decreased in the groups with vegetable seed oil were less than that of the control group. The results suggested that all the five kinds of vegetable seed oil had the effect of regulating lipid metabolism of hyperlipidemia rats to some extent. Pinon seed oil and borage seed oil may be well suited for the prevention of atherosclerosis.
