Effects of pituitary adenylate cyclase-activating polypeptide (PACAP38) and PACAP27 on the cardiovascular and respiratory systems were examined and compared to those of vasoactive intestinal polypeptide (VIP) in anesthetized beagle dogs. Intravenous PACAP27 and PACAP38 produced a decrease in mean arterial blood pressure (MBP), and an increase in both femoral arterial blood flow (ABF) and in frequency of respiration (FR) with a dose-dependent relationship between 10 and 300 pmol/kg. PACAP27 produced a dose-dependent increase in heart rate (HR) between 10 and 300 pmol/kg while PACAP38 induced tachycardia which was not dose-dependent. Administration of 300 pmol/kg PACAP38 and PACAP27 produced extreme hypertension after transient hypotension. PACAP38 produced severe bradycardia after transient tachycardia. The cardiovascular actions of PACAP38 were persistent compared to those of PACAP27. Intravenous injection of 10-300 pmol/kg VIP brought about hypotension, tachycardia and an increase in ABF and FR with a dose-dependent relationship. VIP, at 2000 pmol/kg, did not produce the biphasic response obtained by a large dose of PACAP38. The present studies demonstrate that PACAP partially possesses VIP-like cardiovascular and respiratory actions and that the C-terminal 11 amino acid residues of PACAP38 are presumably responsible for a prolongation of its actions.
