摘要
目的探讨血管紧张素转化酶抑制剂对动脉粥样硬化家兔血管血凝素样氧化型低密度脂蛋白受体1表达的影响。方法以家兔动脉粥样硬化模型为研究对象,采用免疫组织化学和逆转录聚合酶链反应方法评价动脉粥样硬化家兔血管血凝素样氧化型低密度脂蛋白受体1蛋白和信使核糖核酸表达及口服雷米普利的干预效应。结果高脂组血管血凝素样氧化型低密度脂蛋白受体1蛋白和信使核糖核酸表达均显著增加,雷米普利组血管血凝素样氧化型低密度脂蛋白受体1蛋白和信使核糖核酸表达水平较高脂组显著下降(P均<0.05)。结论结果提示,服用雷米普利可明显抑制动脉粥样硬化病变血管血凝素样氧化型低密度脂蛋白受体1蛋白和信使核糖核酸表达,从而可能在动脉粥样硬化的预防中起重要作用。
Aim To investigate the effects of Ramipril on expression of lectin-like oxidized low density hpoprotein receptor-1 (LOX-1) in a rabbit model of atherosclerosis. Methods Twenty-four male New Zealand white rabbits were randomly divided into three groups: normal diet group, hypercholesterol diet group and Ramipril-treated group. Expression of lectin-like oxidized low density lipoprotein receptor-1 in a rabbit model of atherosclerosis was detected by immunochemistry and reverse transcription polymerase chain reaction (RT-PCR). Results Expression of LOX-1 in hypercholesterol group significantly increased compared with normal diet group. There was a significant dicrease in expression of LOX-1 in the Ramipril-treated group (P〈0.05). Conclusion Ramipril inhibits vascular LOX-1 expression, which may play an important role in prevention of atherosclerosis.
