title: Effects of synthetic secretin on gastric secretion in man.
abstract: Five healthy subjects received on one occasion 2 mug/kg-hour of pentagastrin alone and on another occasion in combination with synthetic secretin (Schwarz/Mann) in the dose of 2 U/kg-hour. The gastric and duodenal contents were collected continuously through a gastroduodenal Lagerlöf tube. Polyethylene glycol and 57Co labelled vitamin B12 were used as non absorbable markers in the duodenum and in the stomach, respectively. In each subject synthetic secretin inhibited acid (mean inhibition 17 percent) and stimulated pepsin secretin (mean stimulation 49 percent). The findings indicate that these actions are properties of secretin itself.
