摘要: 目的: 通过两两药物联合应用治疗高血压,观察并对比药物联合治疗的降压效果, 并探讨其对左室重构的作用 。方法: 用两肾一夹法建立高血压大鼠模型, 43 只 SD大鼠随机分为:假手术组(A 组, n =10) , 高血压组(B 组, n =11) , β-B +ACEI 组 (C 组, n = 11) 予 以 比 索 洛 尔5 mg°kg-1 °d-1及贝那普利 5 mg°kg-1 °d-1灌胃,ACEI +CCB 组 (D 组, n =11) 予以贝那普利5 mg°kg-1 °d-1及氨氯地平 2.5mg°kg-1 °d-1灌胃, 饲养20 周, 期间每两周给大鼠测量鼠尾动脉压和超声心动图, 20 周后采集标本, 用免疫组化法检测胶原 Ⅲ、胶原 Ⅳ及心钠素(ANF) 。结果: 用药组血压 、胶原 Ⅲ、胶原 Ⅳ含量较 B 组明显降低,差异具有统计学意义。与A 组比较, B 组 ANF 明显升高(P<0.05) , 各药物治疗组 ANF 无明显升高;与 B 组比较, 各药物治疗组 ANF 显著降低(P<0.01) 。结论: 在降压和靶器官保护方面, 贝那普利和氨氯地平联用疗效优于贝那普利和比索洛尔联用。

Abstract: AIM: To investigate the effect of combined medication on treating hypertension and explore its role in left ventricular remodeling in renal vascular hypertension rats (two kidney one clip hypertensive rats) . METHODS: Forty-three SD rats were randomly di-vided into 4 groups:sham group (Group A, n =10) , hypertension group (Group B, n =11) , β-B +ACEI group (Group C, n =11 bisoprolol 5 mg°kg-1 °d-1 and benazepril 5 mg°kg-1 °d-1) , ACEI +CCB group (Group D, n =11 benazepril 5 mg°kg-1 °d-1 and am-lodipine 10 mg°kg-1 °d-1) .The rats were fed for 20 weeks, blood pressure and echocardiography of rats were monitored every 2 weeks.After 20 weeks, (rats were sacrificed and the blood and hearts were collect-ed, then the concentrationsof collagen Ⅲ, collagen Ⅳ and ANF were detected by immunohistochemistry .RESULTS: Compared with Group B, the blood pressure, the concentrations of collagen Ⅲ, collagen Ⅳ and ANF in medication groups were significantly reduced. Compared with Group A, the ANF was significantly in-creased in Group B, but the ANF was not significantly increased in medication groups(P<0.05). CONCLUSION: The combined effect of benazepril and amlodipine is better than bisoprolol and benazepril in reducing blood pressure and preventing target organ .
