dc.description.abstractThe study deals with manganese superoxide dismutase, copper, zinc superoxide dismutase, and catalase activities in brain cortex of Wistar rats exposed to acute stress (immobilization or cold for 2 h), chronic stress (long-term isolation or long-term forced swimming for 21 days), or to combined chronic/acute stress. We observed that i) single episodes of acute stress by immobilization increased activity of both superoxide dismutases; ii) both types of chronic stresses significantly elevated activities of all examined enzymes; iii) chronic social isolation was a much stronger stressor than physical stress by swimming; iv) in animals pre-exposed to chronic isolation, additional stress by immobilization or cold significantly decreased previously elevated activities of all enzymes, while after chronic swimming, acute immobilization lowered only catalase activity. The obtained results indicate that stress conditions most probably altered the cell redox equilibrium, thus influencing the antioxidant response in brain cortex. Further investigation of neuronal prooxidant/antioxidant cellular conditions is needed to improve the prevention and treatment of various stress induced diseases.en
