The significance of mangane as an environmental pollutant has increased in previous years. In this study the authors present the influence of chronic exposure of mangane on oxidative stress parameters. Depending on the position in the brain, the authors observed the following changes: decrease of GPx and GR activity in the brain stem, similarly in the cerebellum; in the brain’s hemispheres, however, an increase of GST activity and a decrease of GR activity was observed. CAT activity in all these three structures remained at a lower, constant level.
