...e ameliorative effect of quercetin against cadmium-induced toxicity and oxidative stress in a male Sparaque Dawley rat model. There were four experimental groups with 6 rats in each: Group I control orally received normal saline, Group II orally administrated cadmium chloride (5 mg/kg bw/d), Group III orally administrated cadmium chloride (5mg/kg bw/d) and treated with low dose of quercetin (50 mg/kg bw/d), Group IV orally a...

...e effects of antioxidant quercetin(QCT) were studied on indices of oxidative stress, liver enzymes activity and the expression of cytochrome P450 1A1 (CYP1A1) against hepatotoxicity induced by 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD) in male rat. Thirty adult male Wistar rats randomly divided into five equal groups. TCDD and QCT were orally administered at the dose of 10µg/kg /day and 20 mg/kg/day, respectively by gavage dissolved in corn oil...

The mice received varying doses of quercetin from 22-30 days (1, 10 and 50 mg / kg, p.o.) and montelukast (10 mg / kg, p.o.). Intranasal OVA has been instilled on the 21 days. Biochemical parameters, spleen weight, physiological parameters, interleukin (IL-1β and IL-6) parameters and immunogl...

Half of the rats at each age received 200 mg quercetin/Kg every other day for 2 weeks. Thirty months old rats showed a decrease in the liver AST, albumin, SOD, CAT and GPx while showed an increase in the liver ALT, plasma cholesterol and MDA comparing with 3 mo...
