Bedi BS, Debas HT, Wasunna AE, Buxton BF, Gillespie IE. "Secretin and cholecystokin-pancreozymin in combination in the inhibition of gastric acid secretion.". 2012. Abstract

Both secretin, and the single substance which possesses both cholecystokinin and pancreozymin activity, have been shown to inhibit gastric acid secretory responses. Since potentiation may occur between pairs of stimulants of gastric secretion, the effects of combining secretin and cholecystokinin/pancreozymin have been studied in Heidenhain pouches stimulated by continuous intravenous pentagastrin. Evidence suggesting potentiation between these two inhibitor agents is presented

Buxton B, Wasunna AE, Saunders J, Gillespie IE. "Site of the abnormal stimulus of gastric secretion after small bowel exclusion.". 2007. Abstract

In dogs with either vagally innervated or denervated pouches, the acid responses to a standard meal, a meal which bypassed the greater part of the small bowel, and a meal introduced directly into the small intestine were measured before and after exclusion of 75% of the small bowel.After intestinal exclusion an increase in acid secretion was found in the latter part of the acid response to the standard meal and the intestinal meal. No increase in acid secretion resulted from the meals which bypassed the small bowel. These findings suggest that an increase in stimulation from the remaining small intestine is responsible for the elevation in acid secretion following small bowel exclusion.
