Cell proliferation of the duodenal mucosa in patients affected by familial adenomatous polyposis.

abstract：:We investigated a hormonal mechanism in a trypsin inhibitor-induced pancreatic hypersecretion in rats. Intraduodenal administration of a synthetic trypsin inhibitor, camostat, resulted in significant increases in plasma concentration of both secretin and cholecystokinin in a dose-related manner that paralleled a signi...
