Effect of a combination of gastrin, secretin, cholecystokinin, glucagon, and gastric inhibitory polypeptide on jejunal absorption in man. 1980

P Poitras, and R Modigliani, and J J Bernier

In 11 conscious volunteers, the jejunal absorption was measured during basal state and during the simultaneous intravenous infusion of small doses of gastrin, secretin, cholecystokinin, glucagon and gastric inhibitory polypeptide. The blood levels of gastrin, secretin, glucagon, and GIP were measured by RIA and were close to those achieved after a meal. The basal net absorption of water and electrolytes was reversed to a net secretion during the hormonal infusion. These results suggest that the jejunal secretion observed after a meal in man may be mediated by hormones released by the meal.

D007408	Intestinal Absorption	Uptake of substances through the lining of the INTESTINES.	Absorption, Intestinal
D007583	Jejunum	The middle portion of the SMALL INTESTINE, between DUODENUM and ILEUM. It represents about 2/5 of the remaining portion of the small intestine below duodenum.	Jejunums
D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D002766	Cholecystokinin	A peptide, of about 33 amino acids, secreted by the upper INTESTINAL MUCOSA and also found in the central nervous system. It causes gallbladder contraction, release of pancreatic exocrine (or digestive) enzymes, and affects other gastrointestinal functions. Cholecystokinin may be the mediator of satiety.

D005260	Female		Females
D005749	Gastric Inhibitory Polypeptide	A gastrointestinal peptide hormone of about 43-amino acids. It is found to be a potent stimulator of INSULIN secretion and a relatively poor inhibitor of GASTRIC ACID secretion.

D005755	Gastrins	A family of gastrointestinal peptide hormones that excite the secretion of GASTRIC JUICE. They may also occur in the central nervous system where they are presumed to be neurotransmitters.	Gastrin
D005768	Gastrointestinal Hormones	HORMONES secreted by the gastrointestinal mucosa that affect the timing or the quality of secretion of digestive enzymes, and regulate the motor activity of the digestive system organs.

D005934	Glucagon	A 29-amino acid pancreatic peptide derived from proglucagon which is also the precursor of intestinal GLUCAGON-LIKE PEPTIDES. Glucagon is secreted by PANCREATIC ALPHA CELLS and plays an important role in regulation of BLOOD GLUCOSE concentration, ketone metabolism, and several other biochemical and physiological processes.
