The effect of allopurinol on the liver ultrastructure, reduced glutathione and lipid peroxide levels during liver ischemia in guinea pigs.
1. The preventive effect of allopurinol on reduced glutathione and lipid peroxide levels of the liver and the accompanying ultrastructural changes during liver ischemia was investigated in guinea pigs. 2. Liver glutathione levels decreased significantly while lipid peroxide levels increased slightly in the ischemic group. 3. Allopurinol administered before ischemia resulted in a reverse significant increase in liver glutathione levels and a significant decrease in lipid peroxide levels indicating a protective effect upon cell membrane during ischemia. 4. On the other hand, electron microscopic changes in the liver associated with ischemia could not be altered by allopurinol.
