摘要: 目的 探讨维生素E (Vit E)对冠心病低密度脂蛋白氧化修饰作用。方法 健康对照组32 例, 将45 例冠心病患者分两个剂量组, Vit E 0.1 g/d 及0.3 g/d 。采用给药前后自身对照的方法测定血清氧化低密度脂蛋白(oxLDL)、血清脂质过氧化物(LPO)、全血谷胱甘肽过氧化酶(GSH-Px)、全血超氧化物歧化酶(SOD)。结果 冠心病组oxLDL、LPO 显著升高(P<0.01, P<0.05),GSH-Px显著降低(P<0.01)。Vit E 0.3 g/d 治疗后, oxLDL 和LPO 显著降低(P<0.01), GSH-Px 升高(P<0.01)。结论 Vit E 是一种良好的抗氧化剂, 其抑制低密度脂蛋白的氧化修饰作用是防治冠心病的重要机制之一。

Abstract: Aim The effect of Vitamin E on the oxidation of low denity lipoprotein in coronary heart disease (CHD)was abserued.Methods I n 32 healthy control persons and 45 CHD patients, who were divided into two groups and given Vitmin E 0.1 g qd or 0.1 g tid, po for 4 weeks, the contents of oxidized low densi ty lipoprotein oxLDL, lipid perox ides (LPO)in serum and activities of superoxide dismutase (SOD)and g lutathione peroxidase (GSH-Px)in blood were examined before and after treatment.Results The oxLDL and LPO were significantly hig her in CHD patients than in the controls.after treatment with Vitmin E 0.1 g tid oxLDL and LPO decreased signif icantly (P<0.01)and GSH-Px activity increased markedly (P<0.01).Conclusion Vitamin E was a free radical scavenger and its inhibiting oxidative modification of LDL may be one of its machenisms for prevention and treatment of CHD.

Key words: Vitmin E, oxidized LDL, coronary heart disease, oxygen free radicals
