A small dose of somatostatin inhibits the pentagastrin stimulated gastric secretion of acid, pepsin and intrinsic factor in man. 1978

E Schrumpf, and M H Vatn, and K F Hanssen, and J Myren

The effect of a small dose of somatostatin (0.05 mg/h) on the gastric secretion of acid, pepsin and Intrinsic Factor (IF) after stepwise increases in the dose of pentagastrin was examined in six healthy volunteers. The gastric secretion of acid, pepsin and IF in response to pentagastrin was significantly reduced by a continuous infusion of somatostatin. The pattern of inhibition indicates that somatostatin is a competitive inhibitor of pentagastrin in the stimulation of gastric secretion of both acid, pepsin and IF. This finding supports the hypothesis of a direct effect of somatostatin on the exocrine secretory cells of the stomach.

UI MeSH Term Description Entries
D007437 Intrinsic Factor A glycoprotein secreted by the cells of the GASTRIC GLANDS that is required for the absorption of VITAMIN B 12 (cyanocobalamin). Deficiency of intrinsic factor leads to VITAMIN B 12 DEFICIENCY and ANEMIA, PERNICIOUS. Factor, Intrinsic
D010418 Pentagastrin A synthetic pentapeptide that has effects like gastrin when given parenterally. It stimulates the secretion of gastric acid, pepsin, and intrinsic factor, and has been used as a diagnostic aid. Acignost,Gastrin Pentapeptide,Peptavlon,Pentapeptide, Gastrin
D010434 Pepsin A Formed from pig pepsinogen by cleavage of one peptide bond. The enzyme is a single polypeptide chain and is inhibited by methyl 2-diaazoacetamidohexanoate. It cleaves peptides preferentially at the carbonyl linkages of phenylalanine or leucine and acts as the principal digestive enzyme of gastric juice. Pepsin,Pepsin 1,Pepsin 3
D001786 Blood Glucose Glucose in blood. Blood Sugar,Glucose, Blood,Sugar, Blood
D005750 Gastric Juice The liquid secretion of the stomach mucosa consisting of hydrochloric acid (GASTRIC ACID); PEPSINOGENS; INTRINSIC FACTOR; GASTRIN; MUCUS; and the bicarbonate ion (BICARBONATES).

D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012636 Secretory Rate The amount of a substance secreted by cells or by a specific organ or organism over a given period of time; usually applies to those substances which are formed by glandular tissues and are released by them into biological fluids, e.g., secretory rate of corticosteroids by the adrenal cortex, secretory rate of gastric acid by the gastric mucosa.

D013004 Somatostatin A 14-amino acid peptide named for its ability to inhibit pituitary GROWTH HORMONE release, also called somatotropin release-inhibiting factor. It is expressed in the central and peripheral nervous systems, the gut, and other organs. SRIF can also inhibit the release of THYROID-STIMULATING HORMONE; PROLACTIN; INSULIN; and GLUCAGON besides acting as a neurotransmitter and neuromodulator. In a number of species including humans, there is an additional form of somatostatin, SRIF-28 with a 14-amino acid extension at the N-terminal.
