目的:探讨白川胶囊对自发性高血压大鼠(SHR)血压、左心肥厚(LVH)及血浆中血管紧张素Ⅱ(AngⅡ)和醛固酮(ALD)含量的变化的影响。方法:选取自发性高血压大鼠和京都种Wistar大鼠(WKY)分别作为模型对照和正常对照,用白川胶囊进行为期3个月的干预,期间监测血压变化,卡托普利作为阳性对照药。大鼠处死后称量左心室质量并计算左心肥厚指数,对左心室进行病理生态学观察,用放射免疫法测定血浆中AngⅡ和ALD。结果:白川胶囊在平稳降压的同时可以抑制左心肥厚,并且显著下调大鼠血浆中AngⅡ和ALD的水平。结论:白川胶囊对SHR大鼠的左心肥厚及血浆中AngⅡ和ALD水平有一定的抑制作用。
Objective: To investigate the effects of Bai-Chuan capsule(BC) on the Left Ventricular Hypertrophy in spontaneously hypertensive rats(SHR).Methods:Taking SHR and Wistar Kyoto rats(WKY) as the model group and the control group respectively,Captopril as positive drug,administered BC 0.3 g/kg,Captopril 3.75 mg/kg or 0.5% CMC-Na to each group by ig for 3 months,and measured the change of blood pressure.The left ventricular mass index was calculated after rats were sacrificed.Left ventricle was used to pathological observations,plasma angiotensinⅡ and aldosterone were measured by radioimmunoassay.Conclusion:BC can inhibit left ventricular hypertrophy,plasma level of angiotensinⅡ and aldosterone to some extent in SHR.
