dc.descriptionThis study evaluated the effect of quercetin on oxidative stress in a rat model of L-arginine-induced acute pancreatitis. Thirty male rats were randomly divided into five experimental groups thus: control, L-arginine group (2g/Kg body weight, i.p), and other groups were treated with 12.5mg/Kg body weight, 25mg/Kg body weight and 50mg/Kg body weight an hour after L-argnine administration. Twenty four hours thereafter, the rats were sacrificed and blood collected by cardiac puncture and organs were excised for the assay of plasma lipase and α-amylase activities as well as the activities of some antioxidant enzymes and levels of reduced glutathione, lipid peroxidation and chloramine. Acute pancreatitis was assessed by a significantly (p < 0.05) increase in the activities of plasma lipase and α-amylase 24hours after L-arginine administration. All the quercetin dosages significantly (p < 0.05) reversed the activities of these enzymes. L-arginine administration resulted in significant (p < 0.05) reduction in the activity of glutathione-s-transferase in the lungs, pancreas and spleen as well as in the level of erythrocyte reduced glutathione. Only rats treated with 50mg/kg quercetin had a significant (p < 0.05) reversal. However, all the quercetin treated groups had significant (p < 0.05) increase in the level of erythrocyte reduced glutathione. Superoxide dismutase and peroxidase activities significantly (p < 0.05) reduced while myeloperoxidase activity significantly (p < 0.05) increased in the organs of rats as a result of L-arginine administration. These alterations were prevented by quercetin. These results show that quercetin protects the rat tissues from oxidative damage in L-arginine-induced pancreatitis. •
