PG - 1303-8 AB - The effects of centrally administered pituitary adenylate cyclase-activating polypeptide (PACAP-38) on body temperature were investigated in rats. Intracerebroventricular (i.c.v.) administration of PACAP-38 in doses of 500 and 1000 ng induced a dose-related elevation in colon temperature 2, 3, 4, 5 and 6 h after injection. The i.c.v. pretreatment of the animals with different dilutions of PACAP-38 antiserum prevented the development of hyperthermia in PACAP-38-treated animals, whereas PACAP-38 antiserum alone did not modify the colon temperature. An intramuscular injection of noraminophenazone (a cyclooxygenase inhibitor) abolished the PACAP-38-induced hyperthermia. Our data indicate that PACAP may induce hyperthermia via the central nervous system, and this hyperthermic effect may be mediated via a cyclooxygenase-involved pathway.
