摘要
目的 :探讨中药双龙丸干预动脉粥样硬化的分子学作用机制 ,主要是对血小板衍化生长因子 A(PDGF A)、单核细胞趋化蛋白 1(MCP 1)mRNA表达的影响。方法 :采用培养的家兔动脉粥样硬化细胞模型 ,用高脂血清造成动脉粥样硬化细胞模型 ,用中药血清药理学方法将药物血清作用于细胞模型 ,采用逆转录 -聚合酶链式反应 (RT PCR)方法 ,观察双龙丸对PDGF A、MCP 1mRNA表达水平的影响。结果 :高脂血清能刺激细胞表达PDGF A、MCP 1mRNA ,双龙丸药物血清能使PDGF A、MCP 1mRNA表达水平降低。结论 :双龙丸能抑制细胞自分泌生长因子功能 ,这是其干预动脉粥样硬化的药理作用机制之一。
