Mice also were orally administered with alcohol and water extracts of thyme and ginger in concentration of 500 mg/kg body weight for 2 weeks.
Results: The results showed very highly significant increase in nitric oxide and malondialdehyde level in liver and brain and a very highly significant decrease in the total antioxidant capacity and glutathione peroxidase activity in alcoholic group. In addition, the liver function enzymes such as L-gamma-glutamyl transpeptidase and butyryl cholinesterase activities showed very highly significant increase in alcoholic group. in contrast, the water extracts of thyme and ginger showed significant amelioration on these changes both in liver and brain tissues.
