Translations

Gastrin

gastrin

[′gas·trən] (biochemistry) A polypeptide hormone secreted by the pyloric mucosa which stimulates the pancreas to release pancreatic fluid and the stomach to release gastric acid.

Gastrin

a polypeptide hormone secreted by the mucous membrane of the pylorus of the stomach; it is secreted when the pylorus is stretched or acted on by chemical stimulants (for example, products of the decomposition of food) or impulses from the vagus nerves. Gastrin increases the secretion of gastric and pancreatic juices, as well as of bile, and alters the tone and motility of the stomach and intestines. An increase in the hydrochloric-acid content of the pylorus (when acidic gastric juice enters it) inhibits the secretion of gastrin. Two kinds of gastrin, which are very similar in structure and physiological properties, have been distinguished. Gastrin has been synthesized chemically.

gastrin

[gas´trin] a polypeptide hormone secreted by certain cells of the pyloric glands, which strongly stimulates secretion of gastric acid and pepsin, and weakly stimulates secretion of pancreatic enzymes and gallbladder contraction.

gastrin

(găs′trĭn)n. A hormone secreted by glands in the mucous membrane of the stomach that stimulates the production of gastric juice.

gastrin

A peptide hormone secreted by the stomach on the stimulus of the sight, smell or contemplation of food. The hormone is released into the blood. The entry of protein into the stomach stimulates even more gastrin production and this hormone returns to the stomach to stimulate the production of acid and pepsin (GASTRIC JUICE) from the cells of the stomach lining (gastric mucosa).

gastrin

a hormone produced by gastrin cells of the pyloric gland, which induces gastric secretion.

Gastrin

A hormone secreted in the stomach that is involved in the production of gastric acid. Overproduction of gastric acid contributes to peptic ulcer formation.Mentioned in: Gastrinoma, Ulcer Surgery
