摘要: 目的:探讨红曲与葡萄籽原花青素(GSPE)混合剂对大鼠高脂血症的改善及对血清氧化性低密度脂蛋白的影响。方法:将60只大鼠按总胆固醇(TC)水平随机分为基础对照组、模型对照组及混合剂低、中、高三个剂量组,采用30万IUVD3/kg·d连续3d灌胃后,配合高脂饲料,复制大鼠动脉粥样硬化模型。空白对照组饲喂基础饲料,其余实验组饲喂高脂饲料;空白组及模型组灌胃蒸馏水,三个剂量组灌胃不同剂量混合剂,连续10周。在实验第2、4、6、8、10周测定血清总胆固醇(TC)、甘油三脂、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇(ox-LDL)、氧化性低密度脂蛋白及血清SOD、MDA、GSH-Px、T-AOC水平。结果:三个剂量组大鼠血清血脂水平(TC、TG、LDL-c)及ox-LDL明显降低,血清抗氧化能力(SOD、GSH-Px、T-AOC)提高,中、高剂量组效果优于低剂量组。结论:红曲及葡萄籽原花青素能缓解大鼠高脂血症,降低ox-LDL水平,提高机体抗氧化能力,延缓动脉粥样硬化的发生。

Abstract: Objective: To observe the effects of liquid mixture of Monascus and grape seed procyanidins extract (GSPE) on levels of cholesterol and ox-LDL of atherosclerosis rats. Method: The models were developed by administering vitamin D3 and feeding high cholesterol diet. Serial assays of blood cholesterol, triglycerides, HDL-c, LDL-c, ox-LDL of the rats were performed and antioxidant statuses such as SOD, MDA, GSH-Px, and T-AOC were also detected. Results: Compared with those of rats in control group, serum TC, TG, HDL-c, LDL-c and ox-LDL levels of model rats significantly increase. Increases of TC, TG, LDL-c and ox-LDL levels of the rats are inhabited in three experimental group, and the antioxidant statuses are inproved significantly (p< 0.05). But there is no significant difference among HDL-c levels in these groups. Conclusions: The liquid mixture of Monascus and GSPE can delay the progress of the formation and development of atherosclerosis by various pathways.
