Abstract
Four episodes of immobilization stress cause a decrease in the sensitivity to glucocorticoid hormones, followed by anxiogenic behavioral disorders, enhanced monoamine oxidase-В (МАО-В) activity and simultaneously increased lipid peroxidation (LPO) in the brain tissue of rats. Concurrently, there is an increase in renal МАО-В activity, as well as renal and hepatic accumulation of LPO products. Administration of kenalog (2 mg/kg), a pharmacological analogue of glucocorticoid hormones, prevents the poststress МАО-В activation and LPO and attenuates anxiogenic behavioral disorders in the rats.
