Abstract

The objective of this study was to ascertain the effect of dehydroepiandrosterone-sulphate (DHEA-S) on changes of anxiety level, induced by corticotropin-releasing hormone (CRH) injection. Active and passive rats were selected from Wistar rats on the basis of T-maze testing. Active rats were then divided into the groups with high (HA) and low anxiety (LA) level after testing in elevated-plus maze. Intranasal injection of CRH induced increase of anxiety level in the LA rats, while in HA rats it remained unchanged. DHEA-S exerted a moderate anxiolytic effect on the LA rats and sedative effect--on the HA rats. DHEA-S injection had no effect on anxiety level in passive rats that typically demonstrate high level of trait-anxiety and resistance to CRH. These results suggest that DHEA-S effect depends on the individual psycho-emotional status and responsiveness to CRH.
