摘要
对实验性高血脂小鼠分别用1.2%和2.4%的苦丁茶水灌胃45d后,取尾血测定其血清总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-c)含量和卵磷脂胆固醇酰基转移酶(LCAT)的相对活性,并计算出低密度脂蛋白胆固醇(LDL-c)和极低密度脂蛋白胆固醇(VLDL-c)浓度及动脉硬化指数(AI),并与绞股蓝茶的降脂作用进行比较。结果表明,饮用苦丁茶可以明显降低实验性高血脂小鼠的TC、TG和LDL-c、VLDL-c(P<0.01或P<0.05),显著升高HDL-c含量及HDL-c/TC(P<0.01或P<0.05),而作为阳性对照的绞股蓝茶组HDL-c与高脂组比较无显著差异.二个苦丁茶组与绞股蓝茶组的LDL-c/HDL-c及LCAT相对活性均与高脂组有显著差异(P<0.01),与对照组则无明显差异。由此说明,苦丁茶具有降血脂、防治动脉粥样硬化的作用,提示苦丁茶的降脂机理与其能够升高LCAT相对活性有关。
For observation of the effect of Kudingcha on experimental hyperlipidemia inmice,study was performed by using Kudingcha's fitrate of two kinds of concentration.After 45days treatment,the average values of serum total cholesterol and triglyceride and low densitycholesterol were decreased significantly(P<0.01 or P<0.05),and the average values of highdensity lipoperotein cholesterol were increased markedly(P<0.01 or P<0.05).The Arte-riosclerosis Index:ratio of serum high density lipoprotein cholesterol in total cholesterol was in-creased from 0.24 to 0.44 and 0.41.The specific ratio of low density lipoprotein cholesterol inhigh density lipoprotein cholesterol was decreased from 3.10 to 1.31 and 1.37.The ralative ac-tivities of Lecithin-cholesterol acyItransferace(LCAT)were increased significantly(P<0.01).Therefore Kudingcha is supposed to have good decreasing lipemia effect.[
