Functional comparisons of gastrin/cholecystokinin receptors in isolated preparations of gastric mucosa and ileum.


1. The gastrin cholecystokinin (CCK) receptors mediating stimulation of acid secretion in rat isolated gastric mucosa (RGM) and contraction in guinea-pig isolated ileum longitudinal muscle-myenteric plexus (GPI) have been characterized by use of peptide agonists and the non-peptide antagonists, lorglumide, devazepide and L-365,260. 2. In RGM, gastrin… (More)
