摘 要: | 目的:探讨瓜蒌薤白类方(自拟复方萎薤合剂)对实验性动脉粥样硬化(amerosclerosis,AS)大鼠血管内皮功能的影响。方法:采用高脂饲料喂养wister大鼠制备动脉粥样硬化模型。大鼠按体重进行随机分组设计,分为4组,各10只,正常对照组(A组)、高脂模型组(B组)、高脂瑞舒伐他汀治疗组(C组)和高脂复方萎薤合剂治疗组(D组),共饲养干预10周。在0周和10周末取大鼠血浆,测定内皮素(ET-1)、一氧化氮(NO)和一氧化氮合酶(NOS)。结果:B组0周与10周时血浆NO、NOS水平明显降低,ET-l水平明显上升。瑞舒伐他汀和复方蒌薤合剂均可提高血浆NO和NOS水平,降低ET-1水平。结论:中药复方蒌薤合剂通过升高血浆NO、NOS水平,降低ET-1水平,对内皮功能有保护作用。

Abstract: | Objective:To investigate effects of TCM Louxie mixture on vascular reactivity in atherosclerosis rats. Methods:Forty male rats were randomly divided into four groups:the control group (A group, n=10) was fed with normal diet;the model group (B group, n=10), atorvastatin treated group (C group, n=10), TCM Louxie mixture treated group (D group, n=10). Serum endothelin-1 (ET-1), nitric oxide (NO) and nitric oxide syntheses (NOS) were observed in different groups before and after the treatment. Results:Rosuvastatin and Louxie mixture can improve the level of plasma NO and NOS, and lower the level of ET-1. Conclusion:TCM Louxie mixture can improve endothelial function in atherosclerosis rats. |
