Role of fenofibrate alone and in combination with telmisartan on renal ischemia/reperfusion injury
2010
It was demonstrated that fenofibrate and telmisartan exerted renoprotective effects in ischemia/reperfusion (I/R) injury. Because the combination of fenofibrate and telmisartan synergistically enhanced peroxisome proliferator-activated receptor (PPAR) activation, we hypothesized that the combination of both drugs may exert prolonged beneficial effects in renal I/R injury than fenofibrate alone. Forty-eight male Wistar albino rats were divided into eight groups. Hyperlipidemia was induced by cholesterol feeding for 4 weeks. At the end of the fourth week, renal I/R injury was performed by occlusion of both renal vascular pedicles for 60 minutes, followed by 24 hours of reperfusion. In the treatment group, fenofibrate alone and in combination with telmisartan was administered 2 weeks prior to renal ischemia. At the end of the experiment, blood and kidneys were isolated for biochemical and histological analysis. I/R in hyperlipidemic rat shows significantly increased lipid peroxidation, nitric oxide, and myel...
