Thioacetamide (TAA) is a potent hepatotoxin that causes centrilobulal necrosis and nephrotoxic damage following acute administration. Prolonged exposure to TAA can result in bile duct proliferation and liver cirrhosis histologically similar to that caused due to viral hepatitis infection. Coriander in food increases the antioxidant content, acting as a natural antioxidant and inhibiting undesirable oxidation processes. The present study investigated the antioxidant activity of Coriandrum sativum on TAA-induced hepatotoxicity in the male rats. Phenolic content and antioxidant activity were evaluated in the coriander leaves and seeds. Forty-eight adult male rats were divided into four groups. Group I (control), group II (TAA injected rats), group III (TAA injected rats fed coriander leaves) and group IV (TAA injected rats fed coriander seeds). The results revealed that serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activities were significantly increased in the groups II, III and IV as compared to the normal control. Oxidative stress in the group II was manifested by a significant rise in nitric oxide (NO), thiobarbituric acid reactive substance (TBARS) levels and myloperoxidase (MPO) activities in the liver tissues as compared with the control group. Rats fed with coriander leaves and seeds showed a decrease in the serum ALT, AST and ALP activities and in the liver NO and TBARS levels as compared to the group II. Histopathological study revealed that coriander feeding attenuated TAA-induced hepatotoxicity in the rats. In conclusion, coriander leaves attenuate hepatotoxicity induced by TAA more than that of seeds due to the higher content of phenolic compounds and antioxidants in the leaves of coriander. Liver of rats intoxicated with TAA exhibited advanced CIRRHOSIS: in the form of macronodular and micronodular structure surrounded by fibrous tissue. Treatment with coriander leaves and seeds helps in improving the adverse effect of TAA-induced hepatotoxicity; also the histological study confirms this finding.
