title: Presence of PACAP and VIP in embryonic chicken brain.
abstract: The aim of the present article was to investigate the occurrence and temporary changes of pituitary adenylate cyclase-activating polypeptide (PACAP)-38 and vasoactive intestinal peptide (VIP) in various brain areas of chicken embryos by means of radioimmunoassay. The highest concentrations of PACAP-38 were measured in the brain stem followed by the hypothalamus, cerebellum, and telencephalon. PACAP-38 levels were significantly higher than those of VIP in all examined brain areas. The levels of both PACAP-38 and VIP showed a tendency to decrease until hatching during embryonic development of the chicken.
