title: Glutathion peroxidase and glucose-6-phosphate dehydrogenase activities in bovine blood and liver.
abstract: A total of 46 cattle, including 25 as control, 16 with glycogen degeneration and 5 with severe fatty degeneration were studied. Whole blood and liver tissue specimens were used to measure glutathione peroxidase (GSH-Px) and Glucose-6-Phosphate Dehydrogenase (G6PD) activities. The present study determined the value of these parameters in diagnosing glycogen and fatty degeneration in cattle from the point of the status of antioxidation and lipid peroxidation. The results showed a significant decrease in hepatic GSH-Px activity and a significant increase in hepatic G6PD activity in cases of fatty degeneration. On the other hand, there were no significant changes in erythrocytic and hepatic GSH-Px and G6PD activities in cases of glycogen degeneration. The results indicated lipoperoxidation process in the liver tissues increased in cases of fatty degeneration. Therefore, supplying animals suffering from fatty liver with sufficient quantities of nutrient antioxidants may be valuable when treatment is considered.
