摘要 目的:观察芪蛭合剂对大鼠实验性动脉粥样硬化主动脉壁MMP-9表达的影响。方法:利用高脂饮食合VD3灌胃成功建立大鼠动脉粥样硬化模型。大鼠随机分为模型组、芪蛭合剂组、辛伐他汀组、血脂康组及空白对照组共5组,10周后处死动物,截取主动脉制作切片,光镜下观察主动脉病理学改变及免疫组化方法观察主动脉MMP-9表达的影响。结果:模型组有明显的动脉粥样硬化斑块形成。各组动物粥样斑块程度较模型组均明显减轻,芪蛭合剂、西药组与模型组相比,有显著差异(P<0.01)。中成药与模型组比较有明显差异(P<0.05):正常动脉组织MMP-9表达极低,呈阴性或弱阳性表达;模型组与空白组比较,MMP-9的表达显著增加(P<0.01),呈强阳性表达。与模型组相比,芪蛭合剂组和西药组最能有效降低MMP-9表达,均呈显著性差异(P<0.05),中成药组亦能降低表达,但与模型组相比,无统计学意义(P>0.05)。结论:芪蛭合剂能够有效的抑制大鼠实验性动脉硬化主动脉MMP-9的表达而达到抗动脉粥样硬化形成、稳定动脉粥样斑块的作用。
