Popis: | The role of prostaglandins (PGs) on the corticotropin-releasing hormone (CRH)- and vasopressin (AVP)-induced pituitary-adrenocortical response under basal and social stress circumstances was investigated. Crowding stress applied for 3 days did not diminish the CRH-elicited corticosterone response, but it considerably reduced such a response to AVP. In control rats systemic or icv pretreatment with indomethacin, an inhibitor of PGs synthesis, did not affect the corticosterone response to ip or icv CRH administered 15 min later. By contrast, ip or icv pretreatment with indomethacin considerably reduced the corticosterone response to AVP given by either route in control rats. Similarly, ip pretreatment with indomethacin further reduced the corticosterone response to AVP already diminished by crowding stress. These results indicate that hypothalamic and anterior pituitary PGs are not involved in the CRH-elicited pituitary- adrenocortical response, but they significantly mediate this response to AVP under both basal and social stress circumstances. |
