摘要
目的:探讨小檗碱对动脉粥样硬化损伤的保护作用。方法:将56只大鼠,随机分为对照组(C),高脂饮食假手术组(HD),肾动脉狭窄组(RAS),肾动脉狭窄高脂饮食组(HD+RAS)。C及RAS组给予正常饮食,HD及HD+RAS组给予高脂饮食,RAS及HD+RAS组采用固定内径银夹夹左肾动脉。饲养12周,每组处死6只进行检测,剩余除C外每日灌胃小檗碱(150mg/kg),C予以等量生理盐水灌服,持续4周,四周后处死进行相同检测,用药前后结果进行对比评价小檗碱功能。结果:与C相比,HD,RAS,HD+RAS组肌酐显著升高(P<0.05),HD及HD+RAS组胆固醇明显升高(P<0.05),超氧化物歧化酶(SOD)在HD,RAS及HD+RAS组显著降低(P<0.05),丙二醛(MDA)在HD,RAS及HD+RAS组显著增高(P<0.05),血管内皮生长因子VEGF在HC,RAS及HD+RAS组表达量升高。给予小檗碱灌胃处理后,检测指标各组间无统计学差异(P>0.05)。结论:小檗碱对动脉粥样硬化性损伤具有良好的保护作用。
Objective:To investigate the protect effect of Berberine on atherosclerotic injury.Methods:Fifty-six rats were randomly divided into control group(C),high-fat diet group(HD),renal artery stenosis group(RAS),high-fat diet with renal artery stenosis group(HD+RAS),fourteen in each group.C and RAS were given proper diet,HD and HD+RAS were given high fat diet.RAS and HD+RAS were clamped by sliver clip with a fixed diameter on left renal artery.12 weeks later,executed six of every group for testing,the left were given Berberine(150mg/kg) every day except C,C were given saline.4 weeks later,the left rats were executed for the same testing.Results:Compared with C,Creatinine was significantly higher in other three groups(p〈0.05).Cholesterol was significantly higher in HD and HD+RAS groups(p0.05).SOD was Significantly higher while MDA was Significantly lower in HD,RAS and HD+RAS group.The ex-pression of VEGF was significantly higher in HD,RAS and HD+RAS group.After given berberine,the testing results had no significant difference in different groups.Conclusions:Berberine has good protection effect on atherosclerotic injury.
