摘要 目的观察潜阳合剂(以下简称QYHJ)干预自发性高血压大鼠(SHR)的降压作用。方法将11周龄雄性SHR 40只随机分为5组:QYHJ高、中、低剂量3组,福辛普利组和模型对照组,每组8只。另以8只同周龄雄性WKY大鼠为正常对照组。QYHJ高、中、低剂量组给药剂量分别为22.94,11.47和5.74 g/kg,福辛普利组给药剂量为0.9 mg/kg,连续给药8周。模型对照组和正常对照组给予等量双蒸水。用药前及用药后每2周均以鼠尾测压法测量血压及心率,各测3次取平均值。结果模型对照组大鼠心率、血压均较正常对照组增高(P<0.001);药物干预后,福辛普利组和QYHJ高剂量组较模型对照组降低(P<0.001,P<0.01);14周龄时,福辛普利组心率较同周龄模型对照组降低(P<0.01);18周龄时,QYHJ高剂量组心率较同周龄模型对照组降低(P<0.001)。福辛普利组、QYHJ高、中剂量组大鼠血压较模型对照组降低(P<0.001),QYHJ不同剂量组间比较显示,QYHJ高、中剂量组大鼠血压较QYHJ低剂量组降低(P<0.001);QYHJ高剂量组较QYHJ中剂量组降低,但比较无显著性差异。14周龄时,福辛普利组血压较同周龄模型对照组降低(P<0.05);16周龄时,QYHJ高、中剂量组血压较同周龄模型对照组降低(P<0.001)。结论QYHJ具有降低SHR心率和血压的作用,QYHJ的降压作用呈一定的剂量相关性,其降压作用和缓。
