ABSTRACT
Objective:To study the protective effect of telmisartan on rats with renal failure and its mechanism. Methods:60 Wistar rats were chosen as study objective, and were divided into 4 groups randomly:15 in group A (sham operation group), 15 in group B (model group), 15 in group C (telmisartan group) and 15 in group D (telmisartan+GW9962 group). The difference of survival rate, blood-urine biochemical indexes, renal pathological change, and the expression level of PPARγ and nNOS were compared. Results:After 12 weeks, the survival rate of group A was 93.33%(14/15), that of group B was 46.67%(7/15), that of group C was 86.67%(13/15), that of group D was 60.00%(9/15), and the difference among 4 groups had statistical significance (P0.05);after 3 weeks, 6 weeks and 12 weeks, these difference was statistical significant (P<0.05). The difference of blood-urine biochemical indexes, that of renal pathological change, and that of the expression level of PPAR毭and nNOS was statistical significant (P<0.05). Conclusions:Telmisartan has protective effect on renal failure caused by 5/6 nephrectomy, which might be relative to the expression level of PPARγ and nNOS.
