Özet

Pituitary adenylate cyclase activating polypeptide (PACAP) is a novel neuropeptide and has two amidated forms, PACAP-27 and PACAP-38. Its chemical structure is similar to that of vasoactive intestinal peptide (VIP). In our previous studies, we found that PACAP has a stimulatory effect on rat exocrine pancreas secretion and an inhibitory effect on rat gastrointestinal motility. These effects of PACAP-27 were greater than those of PACAP-38 and VIP. In the present study, we examined the effect of PACAP-27 on basal and pentagastrin (PG)-stimulated gastric acid secretion in conscious rats and compared its effect with that of VIP.
