Hesperetin protects against oxidative stress related hepatic dysfunction by cadmium in rats.
Exp Toxicol Pathol 2012; 64(5):513-20ET

Abstract

The present study was to evaluate the hepatoprotective effect of hesperetin (HTN) on cadmium (Cd) induced hepatotoxicity in male Wistar rats. Administration of Cd (3 mg/kg body weight/day) subcutaneously for 21 days, the levels of hepatic markers such as aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), gamma glutamyl transferase (GGT) and bilirubin were significantly increased in serum. The levels oxidative stress markers, thiobarbituric acid reactive substances (TBARS), lipid hydroperoxides (LOOH), conjugated dienes (CD) and protein carbonyl content (PCC) were also significantly increased while the levels of vitamin C, vitamin E, reduced glutathione (GSH), total sulphydryl group (TSH) and the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione-S-transferase (GST), glutathione reductase (GR) and glucose-6-phosphate dehydrogenase (G6PD) were significantly decreased in the liver of Cd intoxicated rats. HTN, a flavanone in citrus fruits, administrated orally along with Cd injection for 21 days, significantly revert back the status of serum hepatic markers, oxidative stress markers and antioxidant markers in the liver tissue to near normal level in a dose dependent manner. HTN at a dose of 40 mg/kg body weight/day exhibits significant (p<0.05) hepatoprotection compared with other two doses (10 and 20 mg/kg body weight/day). The histopathological studies in the liver of rats also supported that HTN (40 mg/kg) markedly reduced the toxicity of Cd and preserved the histoarchitecture of the liver tissue to near normal. Thus, the results suggest that HTN acts as a potent hepatoprotective agent against Cd induced hepatotoxicity in rats.
