| Résumé : | It is well established that duodenal acidification strongly inhibits gastric acid secretion, gastric emptying rate and gastrin release. These effects are at least partly mediated via hormonal pathways, but it is not known wether they are mediated by the release of one peptide named in the past enterogastrone, or by several peptides acting together. The effects of duodenal acidification on gastric acid secretion and gastrin release can be reproduced by infusion of small doses of secretin and plasma secretin levels increase during duodenal acidification or after a meal. This peptide is thus the most probable candidate as an enterogastrone. It has however never been clearly shown that administration of low doses of secretin do decrease gastric emptying rate as well as acid secretion. Experiments were performed on four dogs with gastric fistulas. A peptone solution was infused into the stomach. The experiments were repeated during infusion of synthetic secretin. Our results indicate that infusion of low doses of secretin reproduce all the effects of duodenal acidification : a significant inhibition of gastric acid secretion, gastrin release and gastric emptying rate. © 1983 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted. |
