title: Developmental study of rat brain glutathione peroxidase and glutathione reductase.
abstract: Glutathione peroxidase and glutathione reductase activities were measured in whole rat brains at selected ages from birth to adulthood. On a wet weight basis glutathione peroxidase activity increased 70% during development and glutathione reductase activity increased 160%. On a protein basis glutathione peroxidase declined slightly in activity during the first two weeks of life and then maintained the 14-day activity into adulthood while glutathione reductase showed a 30% increase in activity. While less than the developmental changes in many enzyme involved in aerobic glycolysis or catecholamine metabolism, these increases do suggest a role in CNS metabolism.
