    Streszczenie angielskie: This study has demonstrated that the short and long form of the pituitary adenylate cyclase-activating polypeptide (PACAP), i.e. PACAP27 and PACAP38, moderately but significantly, and in a concenration (0.5-5 ćM)-dependent manner, stimulated inositol phosphates (IPs) accumulation in myo-[3H]inositol-prelabeled cerebral cortical and hypothalamal slices of chick and duck, and in slices of rat cerebral cortex; both peptides had no effect on IPs formation in rat hypothalamus. Vasoactive intestinal peptide (VIP; 0.5-5 ćM) weakly enhanced IPs accumulation in chick hypothalamus, had no significant action in chick cerebral cortex (in fact there was a tendency to attenuate the IPs response in this tissue), and slighty, but significantly, inhibite the IPs accumulation in rat cerebral cortex. VIP showed no activity in rat hypothalamus. It is cincluded that tha stimulatory action of PACAP on phosphoinositide metabolism in avian cerebral cortex, similar to rat cerebral cortex, is mediated via phospholipase C-linked PAC1 type receptors. In chick hypothalamus, however, there may be a component of VPAC type receptors stimulating IPs formation.
