摘要 目的通过观察参七脉心通胶囊对内皮损伤因子的影响,探讨其抗动脉粥样硬化(AS)的机制。方法选取实验白兔50只,喂高脂饲料饲养,造高脂血症模型,分为AS模型对照组(A)、实验组B、实验组C、(西药)对照组D、(正常)对照组E;通过生化、放免检测,从血管活性物质方面探讨参七脉心通胶囊对内皮损伤因子的影响;采用酶联免疫吸附法(ELISA)测定氧化修饰低密度脂蛋白(oxdlzed low-denslty 1ipoprotein,Ox-LDL)和肿瘤坏死因子154(CD40/CD40L);应用硝酸还原法测定一氧化氮(NO),化学比色法测定一氧化氮合酶(NOS)活性。结果实验组B,C及对照组D,E的Ox-LDL水平明显低于AS模型对照组A,差异有显著性(P<0.01);实验组C及(西药)对照组D,E组NO,NOS活性明显低于模型对照组,差异有显著性(P<0.01)。结论参七脉心通胶囊对内皮损伤因子有明显的抑制作用,进而可能对树突状细胞的黏附和迁移产生抑制作用,影响AS发生的炎症和免疫机制,最终使动脉粥样硬化发生和发展受到抑制并缓解,对脂肪斑块的稳定起到积极的作用。
