摘要: 目的 探讨茶多酚(TP) 对实验性动脉粥样硬化兔的血脂、抗氧化系统及炎症因子的影响。 方法 通过喂养高脂饲料建立兔的动脉粥样硬化模型, 同时连续i.g. 给予茶多酚(100 mg·kg-1·d-1) 或空白溶媒12 周, 测定兔血浆中TC 、TG 、高密度脂蛋白胆固醇(HDL-C) 、低密度脂蛋白胆固醇(LDL-C) 、NO 、C 反应蛋白(CRP) 、IL-6 、TNF-α含量及超氧化物歧化酶(SOD) 、谷胱甘肽过氧化物酶(GSH-Px) 活力, 并观察主动脉病理学形态改变。 结果 给予茶多酚可有效减小高脂饲料引起的兔动脉粥样硬化斑块面积, 同时降低高脂血症兔血浆TG 、TC 、LDL-C 含量(P<0.01), 增加HDL-C 含量(P<0.01) 及SOD 和GSH-Px 活力, 而且可引起NO 、CRP 、IL-6 、TNF-α含量下降(P<0.01)。 结论 茶多酚可以通过降低动脉粥样硬化兔血脂水平、防止脂质过氧化及抑制炎性因子的产生, 从而起到抗动脉粥样硬化的作用。

Abstract: AIM: To investigate the effects of tea polyphenols (TP) on the serum lipid, the anti-oxidant system and inflammaory factor in experimental atherosclerosis (AS) rabbits. METHODS: Experimental AS model of rabbits was made by feeding high fat diet (HFD).All rabbits were treated with TP (i.g., 100 mg·kg -1 ·d-1) or vehicle for 12 weeks.The contents of TC, TG, HDL-C, LDL-C, NO, CRP, IL-6, TNF-α, SOD and GSH-Px in serum were measured.And the pathomorphological changes of aorta were observed. RESULTS: TP could effectively reduce the area of atherosclerotic plaques in HFD treated rabbits.It also decreased the plasma levels of TC, TG and LDL-C in hyperlipemia rabbits(P<0.01).At the same time, TP treatment lead to the up-regulation of plasma HDL-C levels(P<0.01) and SOD, GSH-Px activity.Moreover, it could decrease the plasma levels of NO, CRP, IL-6 and TNF-αin HFD treated rabbits(P<0.01). CONCLUSION: The anti-atherogenic effect of TP seems to be related to reducing serum lipids, preventing lipid hyperoxidation and inhibiting the production of inflammatory factor.
