吲哒帕胺联合依那普利对自发性高血压大鼠的降压效果

目的研究吲哒帕胺联合依那普利对自发性高血压大鼠(SHR)的降压效果。方法40只SHR随机分成四组(n=10):空白对照组、吲哒帕胺组、依那普利组、吲哒帕胺 依那普利组。以灌胃方式分别给予不同剂量药物。观察不同剂量及药物处理状况下,SHR体质量、心率和血压的变化。结果给药期间及给药后,各药物组不同剂量给药对SHR体质量的增长和心率均无明显影响。吲哒帕胺 依那普利组SHR经不同剂量给药后,血压均较给药前显著降低(P均<0.05),其降压程度与单一药物组相比效果更明显(P<0.05)。结论吲哒帕胺联合依那普利比单一降压药更能显著降低SHR的血压。

Antihypertensive effect of indapamide combined with enalapril on spontaneously hypertensive rats

Objective To observe the antihypertensive effect of indapamide combined with enalapril on spontaneously hypertensive rats(SHRs).Methods Forty SHRs were randomly divided into 4 groups: control,indapamide,enalapril,and indapamide enalapril(n=10 in each group).Medicine in varied doses was given to rats by intragastric administration.Variations of weight,heart rate and blood pressure were measured. Results Varied doses of medicine did not exert significant effects to the weight and heart rate of SHRs during and after the administration.In indapamide enalapril group,the pressure of SHRs was significantly decreased with varied doses compared to that before the administration(P<0.05),which was far more effective than the single administration of indapamide or enalapril(P<0.05). Conclusion The combination use of indapamide and enalapril can lead to more significant antihypertensive effect to SHRs than the single use.
