Under conditions of periodic exposures to anxiogenic stress, intensification of LPO in the brain cortex is a glucocorticoid-dependent process. Glucocorticoid receptor antagonist RU38486 prevented increase in monoamine oxidase B activity and content of LPO products of in brain cortex typical of anxiogenic stress. Normalization of LPO intensity under the effect of glucocorticoid receptor antagonist was associated with the correction of stress-induced disturbances.
