the present experiments have been carried out in order to establish whether the stimulatory effect of bombesin on the chicken gastric acid secretion is a direct effect or is mediated by the release of hormones , such as the avian pancreatic petide and/or gastrin . removal of the pancreas , which is known to be the site of starage of the avian pancreatic polypeptide , does not produce any decrease of the stimulant effect of bombesin on gastric secretion .
