title: [Sex differences in the age-related dynamics of the reactivity to physiological stressors in white rats].
abstract: After removal of habitual partners, white female rats revealed a considerable increase in the corticosterone synthesis and secretion. An increase in the hormone secretion but not in its synthesis occurred in young male rats. In ageing male rats, emotional stress induced an increase in the corticosterone synthesis but the hormone did not enter their blood. High responsiveness of the adaptation systems was revealed in female rats through modification of their basal and stress-induced levels of corticosterone during a 72-hour exposure to light and darkness.
