Corticotropin releasing factor (CRF) inhibits gastric acid secretion via both central neural and peripheral mechanisms. We examined whether local gastric factors may mediate the peripheral action of CRF. In pylorus-ligated anesthetized rats, CRF infusion (15 nmol/kg · h) produced roughly 60% inhibition of pentagastrin (16 μg/kg · h)-stimulated acid secretion. Similarly, in the gastric fistula dog, CRF (1 nmol/kg · h) inhibited pentagastrin-induced acid secretion by 74%. This action of CRF did not result from direct inhibition of gastric parietal cells, as concentrations of the peptide ranging from 10-11to 10-6M had no effect on the activity of isolated parietal cells in the unstimulated state or after stimulation with pentagastrin (10-8M), histamine (10-5M), or carbachol (10-5M), against a background of isobutylmethylxanthine (10-4M). To determine whether local hormones may mediate CRFinduced acid inhibition, we examined the peptide's effect on the release of somatostatin and gastrin from cultured canine gastric D and G cells and from isolated perf used rat stomachs. Corticotropin releasing factor in doses ranging from 10-11to 10-6M had no influence on release of either gastric peptide under basal conditions or after stimulation of gas trin with carbachol (10-6M) and somatostatin with isoproterenol (10-8M). These data suggest that the peripheral acid inhibitory action of CFR is mediated by nongastric mechanisms.
