In the present study, we investigated the effect of raw as well as thermally oxidized sunflower oil (commercially available) on ethanol induced hepatotoxicity. Ethanol was given to animals at a level of 20% and sunflower oil at a level of 15%. Results show higher activity of plasma aspartate transaminase (AST) and alkaline phosphatase (ALP) and also higher levels of plasma and tissue cholesterol, phospholipids and triglycerides both in alcohol+raw as well as thermally oxidized oil groups. The level of cholesterol and triglycerides increased significantly in the liver of rats given alcohol alone, alcohol and raw as well as thermally oxidized oil but the level of phospholipids decreased. The activity of phospholipase A and phospholipase C in liver was found to be increased significantly in alcohol alone, alcohol+oil groups as compared to control group. Histopathological changes in the liver of alcohol and alcohol+oil groups were in good correlation with biochemical parameters. The liver samples of alcohol administered rats showed both microvesicular and macrovescicular type of fatty changes, where as alcohol+oil fed groups showed inflammatory cell infiltrate in the portal triad, microvesicular and macrovesicular type of fatty changes and feathery degeneration of hepatocytes. Studies on the phospholipid fatty acid composition in the liver showed the presence of a number of fatty acids in the alcohol and oil treated groups, which are not present in the control group. The results obtained thus indicate hepatotoxic and hyperlipidaemic effects of alcohol and oil given together.

ABSTRACT The protective effect of dendrodoine analog (DA) [4-amino-5-benzoyl-2-(4-methoxy phenylamino) thiazole] at three doses (5, 10, and 15 mg/kg body weight) was investigated on ethanol-induced hyperlipidemia. Hepatotoxicity was induced by administering 7.9 g ethanol/kg body weight for 45 days by intragastric intubation. Our results showed increased activity of aspartate transaminase (AST), alkaline phosphatase (ALP), and gamma glutamyl transferase (GGT) and increased levels of cholesterol, triglycerides, and phospholipids in the plasma of alcohol-given group when compared with normal control group. The levels of tissue (liver and kidney) cholesterol and triglycerides were increased significantly in alcohol control rats when compared with normal control rats. The levels of phospholipids decreased significantly in the liver and kidney of alcohol control rats when compared with normal control rats. The activity of phospholipase A and phospholipase C increased significantly in the liver of alcohol control rats when compared with normal control rats. Intragastric administration of DA at 10 mg/kg body weight effectively lowered the activity of hepatic marker enzymes (GGT, AST, and ALP), phospholipase A, and phospholipase C, and decreased the levels of plasma and tissue lipids. The level of tissue phospholipids increased significantly when DA was administered at a dose of 10 mg/kg body weight along with alcohol when compared with alcohol control group. Thus, we propose that DA exerts a hepatoprotective effect by modulating liver marker enzymes and lipid levels at a dosage of 10 mg/kg body weight.
