Abstract
Oxidative stress is implicated as a common pathologic mechanism contributing to the initiation and progression of hepatic damage in a variety of liver disorders. Present study attempts to evaluate the hepatoprotective activity of picroliv, curcumin and ellagic acid in comparison to silymarin using paracetamol (PCM) induced acute liver damage. Hepatotoxicity was induced by administering a single oral dose of PCM (500 mg/kg) and was assessed by quantifying the serum enzyme activities, phenobarbitone induced sleeping time and histopathological analysis of liver tissues. The antioxidant parameters, malondialdehyde (MDA), reduced glutathione (GSH) and catalase of the liver tissue were also assessed. The herbal drugs were administered for 7 days by oral route at 50 and 100 mg/kg. PCM induced hepatic damage was manifested by a significant increase in the activities of marker enzymes (alanine transaminase, aspartate transaminase and alkaline phosphatase) in serum and MDA level in liver. There was also a significant decrease in activity of GSH and catalase levels. The histopathological examination on toxic models revealed centrizonal necrosis and fatty changes. Pretreatment of mice with picroliv, curcumin and ellagic acid reversed these altered parameters towards normal values, which were compared with silymarin. The normalization of phenobarbitone induced sleeping time suggests the restoration of liver cytochrome P450 enzymes. This study supports the use of these active phytochemicals against toxic liver injury, which may act by preventing the lipid peroxidation and augmenting the antioxidant defense system or regeneration of hepatocytes. These active phytochemicals may be developed as drugs for the treatment of liver diseases.
