摘要
[目的]观察银杏叶提取物EGB761对动脉粥样硬化家兔对氧磷酶-1(PON-1)和氧化低密度脂蛋白(oxLDL)的影响。[方法]将24只日本大耳白兔随机分为正常组、模型组、EGB761组(n=8)。正常组给予普通饮食,模型组和EGB761组高脂饮食10周。EGB761组从第7周起给予EGB761 50 mg/(kg·d)灌胃4周,正常组和模型组给予等量生理盐水。采用酶免疫吸附法(ELISA法)和生化法检测PON-1的活性和含量,ELISA法检测ox-LDL的含量。[结果]模型组PON-1活性和含量明显降低(P<0.05),ox-LDL的含量明显升高,银杏叶提取物组PON-1活性和含量明显升高,ox-LDL明显降低(P<0.05)。[结论]银杏叶提取物EGB761降低ox-LDL、抗动脉粥样梗化(AS)的机制可能与其上调PON-1活性和含量有关。
