title: [Evidence for the secretion of gastrin into the duodenal lumen of man].
abstract: In six healthy male subjects the duodenum was perfused with phosphate buffer and peptone respectively via a double balloon tube. During peptone perfusion secretion of gastrin into the duodenal lumen and serum gastrin rose simultaneously and significantly compared with buffer control. There was a significant but delayed increase of gastric acid secretion. 60 % of the gastrinlike immunoreactivity in duodenal perfusates corresponded to gastrin 1-34 and 40 % to gastrin 1-17 when separated by starch gel electrophoresis and gel filtration.
