ABSTRACT
AIM:
To observe the therapeutic effect of valsartan on cardiac hypertrophy and expression of endothelin-1(ET-1) in myocardium of rats with chronic renal failure and explore the mechanism.METHODS:
24 Sprague Dawley male rats were selected,and performed five-sixths nephrectomy to produce chronic renal failure model.Two weeks after the surgery,the rats were randomly divided into model group,valsartan group,and a sham group was established serving as control group.Systolic blood pressure,BUN and serum creatinine were measured at ten weeks after operation,then the rats were sacrificed to take the hearts for pathological histological examination.Hybridization in situ was used to examine the transcription of ET-1 mRNA in myocardium.RESULTS:
Systolic pressure,heart weight,heart weight index,left ventricular weight mass(LVM) and left ventricular weight mass index(LVMI) in model group increased significantly tenth week after operation.Systolic pressure,heart weight,heart weight index,LVM and LVMI were decreased markedly in rats with five-sixths nephrectomy by valsartan(P
