| Abstract: | Clofibrate treatment was shown to increase the content of reduced glutathione in rat liver and kidney, but did not alter the glutathione level in heart, brain, spleen and small intestine. Clofibrate did not affect the activity of superoxide dismutase, glutathione peroxidase, glutathione reductase and glucose-6-phosphate dehydrogenase in rat liver and heart. The drug decreased the activity of glutathione-S-transferase in the cytosolic fraction of liver homogenate. Glutathione-S-transferase activity in small intestine was also reduced. The administration of clofibrate decreased the content of polypeptides with mol. wt of 22,000 and 24,000 (possible monomers of glutathione-S-transferase) in the cytosolic fraction of liver cells. |
