摘要
观察补肾煎对去势兔动脉粥样硬化血管平滑肌细胞增殖和凋亡的影响及机制。将 2 7只纯种新西兰雌兔随机分为 :A组 (卵巢切除 )、B组 (未切除卵巢 )、C组 (卵巢切除 +补肾煎 ) ,均给予高脂饮食 ,同时注射牛血清白蛋白 0 2 5g/kg ,造成动脉粥样硬化模型 ,12周时比较动脉形态学变化、MTT法测定各组培养血管平滑肌细胞增殖活性、电镜观察、原位末端标记法及流式细胞仪了解各组平滑肌细胞凋亡情况。结果 :C组兔主动脉内膜增生低于A组 ;C组培养平滑肌细胞增殖低于A组及B组 ;C组培养平滑肌细胞凋亡高于A组及B组。结论 :补肾煎可能通过抑制平滑肌细胞的增殖及增加其凋亡而减轻去势兔动脉粥样硬化的形成。
