Related to secretin:cholecystokinin,CCK,secretin test se·cre·tin (sĭ-krēt′n) n. A polypeptide hormone that is produced in the duodenum, especially on contact with acid, and that inhibits gastric secretion of acid and stimulates secretion of bile, insulin, and pancreatic digestive enzymes. ...
First secretin and then cholecystokinin are given to the patient intravenously; then the duodenal juices are analyzed to determine whether adequate levels of bicarbonate and trypsin are secreted. Synonym: secretin injection test Medical Dictionary, © 2009 Farlex and Partners...
cholecystokinin(CCK), and pancreozymin (PZ). Secretin is released from the uppersmall intestine mucosaby the entry of H+ions into theduodenumand this stimulates the centroacinar andductal cellsof the pancreas to secrete the electrolyte-containing fluid. The HCO3−secreted by the pancreas ...

11.Some of the hormones produced include gastrin, secretin, and cholecystokinin, which are secreted in the presence of food, and some of which act on other organs such as the pancreas, gallbladder, and liver. 12.Kern was also closely involved in the secretin theory. 13.Gastrin and cholecysto...
Gastrointestinal hormones contribute to the beneficial effects of Roux-en-Y gastric bypass surgery (RYGB) on glycemic control. Secretin is secreted from duodenal S cells in response to low luminal pH, but it is unknown whether its secretion is altered af
Results of this test can give a good indication of exocrine pancreatic status, and the test is less invasive and expensive than the current "gold standard", secretin-cholecystokinin test. WikiMatrix Obviously, the mediator inducing insulin release following secretin and pancreozymin in man depends...
It is also widely approved and experimentally substantiated that enzyme production from acinar cells is enhanced by gastrin, cholecystokinin-pancreozymin, and cholinergic agents while these compounds do not significantly stimulate the duct cells to secrete water and electrolytes. It is well-known that ...

The rate of basal pancreatic exocrine secretion is generally expressed as a percent of the maximal amount that the pancreas can secrete when stimulated by a secretagogue such as cholecystokinin (CCK). When expressed as a percentage of the maximal pancreatic capacity to secrete enzymes, values for ...
