Tetrahydrocurcumin: effect on chloroquine-mediated oxidative damage in rat kidney.
Tetrahydrocurcumin is an antioxidative substance, which is derived from curcumin, the component of turmeric. In the present investigation, the effect of tetrahydrocurcumin and curcumin against chloroquine-induced nephrotoxicity were studied in female wistar rats. Oral administration of tetrahydrocurcumin significantly prevented the occurrence of chloroquine (970 mg/kg body weight)-induced renal damage. Upon administration of tetrahydrocurcumin to chloroquine-treated rats, the level of lipid peroxidation was significantly decreased while the levels of non-enzymic and enzymic antioxidants were significantly increased in kidney. Oral administration (80 mg/kg body weight) attenuated the chloroquine-induced nephrotoxicity by significantly decreased levels of serum urea and creatinine with significant normalization of creatinine clearance. On administration of tetrahydrocurcumin, the depleted renal antioxidant defense system (enzymatic and non-enzymatic antioxidants) was significantly increased in rats treated with chloroquine. These biochemical observations were supplemented by histopathological examination of kidney section. These results suggest that administration of chloroquine imposes an oxidative stress to renal tissue and that tetrahydrocurcumin protects the oxidative damage associated with chloroquine.[1]References
