  • Title: Inhibitory effect of resveratrol on proteinuria, hypoalbuminemia and hyperlipidemia in nephritic rats.
    Author: Nihei T, Miura Y, Yagasaki K.
    Journal: Life Sci; 2001 May 11; 68(25):2845-52. PubMed ID: 11432450.
    Abstract:
    The effect of resveratrol, a polyphenolic compound present in grapes and other plants, on proteinuria, hypoalbuminemia and hyperlipidemia was studied in rats with glomerulonephritis. The nephritis was induced by an intravenous injection of anti-rat kidney glomerular basement membrane rabbit antiserum. Nephritic rats were given oral intubation of resveratrol (5 mg/day/100 g body weight) for 14 days, while control nephritic rats as well as normal ones were similarly given vehicle alone. By resveratrol treatment, enlargement in liver and kidney due to nephritis induction was significantly reduced, together with partial restoration of nephritis-induced reduction in body weight gain. Both proteinuria and hypoalbuminemia, characteristic symptoms to nephrotic syndrome, were significantly remedied, that is, urinary protein excretion was suppressed and serum albumin concentration was increased by resveratrol treatment. Resveratrol also suppressed significantly hyperlipidemia incident to nephritis, the hypotriglyceridemic action being more prominent than the hypocholesterolemic one. From these results, resveratrol is suggested to be a potent anti-glomerulonephritic food factor capable of suppressing proteinuria, hypoalbuminemia and hyperlipidemia at the same time.
