gastrin

[gas′trin]
Etymology: Gk, gaster, stomach
a polypeptide hormone, secreted by the pylorus, that stimulates the flow of gastric juice and contributes to the stimulus for bile and pancreatic enzyme secretion. Normal findings of blood levels of gastrin are less than 200 pg/mL.

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.
