Abstract/OtherAbstract:

In the present study, we aimed to evaluate the protective effect of sesamin on kidney damage and renal endothelial dysfunction in two-kidney, one-clip renovascular hypertensive rats fed with a high-fat-sucrose diet (2K1C rats on HFS diet). Sesamin was intragastrically administered to 2K1C rats on HFS diet for eight weeks. Then, we measured the levels of serum hydrogen peroxide (H(2)O(2)), total antioxidant capability (T-AOC), renal malonaldehyde (MDA), total-erythrocuprein (T-SOD) and glutathione peroxidase (GSH-P(X)). The expressions of endothelial nitric oxide synthase (eNOS), nitrotyrosine and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase subunit p47(phox) in the left and right renal cortexes were detected by Western blotting. Pathological changes in the left and right renal cortexes were observed by periodic acid-Schiff staining (PAS) and Masson's staining. Treatment with sesamin (120 and 60mg/kg(-1)·d(-1)) in 2K1C rats on HFS diet improved renal function, corrected structural abnormalities, and attenuated renal oxidative stress. Furthermore, sesamin increased eNOS protein expression and reduced nitrotyrosine and p47phox protein expression. These results demonstrated that long-term treatment with sesamin had renoprotective effect and improved renal endothelial dysfunction via upregulation of eNOS expression and reduction of NO oxidative inactivation in both clipped and contralateral kidneys of 2K1C rats on HFS diet, and sesamin may have a favorably therapeutic value in treating chronic kidney disease in patients with hypertension and hyperlipemia. |
