title: Regional distribution of glutathione peroxidase in the adult rat brain.
abstract: Glutathione peroxidase activity was measured in 10 areas of perfused adult rat brain with the use of a fluorometric assay coupled to NADPH oxidation. The caudate-putamen and the substantia nigra had the highest activities. Cortical areas and several nuclear areas had somewhat lower activity. Activity was lowest in a white matter structure (corpus callosum). High activity of glutathione peroxidase may be related to the need to reduce hydrogen peroxide arising in the course of monoamine metabolism.
