The effects of GnRH on gastric secretion and gastrin release from dogs provided with gastric fistulae and Heidenhain pouches have been investigated. A transient yet significant inhibition of pentagastrin-stimulated secretion from gastric fistulae was observed, while secretion from Heidenhain pouches was unchanged. The maximal inhibitory effect of GnRH on both acid and pepsin secretion stimulated by 2-deoxy-D-glucose was obtained from gastric fistulae. On the contrary, GnRH failed to affect either acid secretion stimulated by bethanechol or acid secretion and gastrin release induced by bombesin. The present results indicate that GnRH possesses an inhibitory action on gastric secretion from the vagally innervated stomach of the dog. The most likely inhibitory mechanism seems to be represented by a decrease of the vagal activity.

UI MeSH Term Description Entries
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
D010906 Pituitary Hormone-Releasing Hormones Peptides, natural or synthetic, that stimulate the release of PITUITARY HORMONES. They were first isolated from the extracts of the HYPOTHALAMUS; MEDIAN EMINENCE; PITUITARY STALK; and NEUROHYPOPHYSIS. In addition, some hypophysiotropic hormones control pituitary cell differentiation, cell proliferation, and hormone synthesis. Some can act on more than one pituitary hormone.

D001839 Bombesin A tetradecapeptide originally obtained from the skins of toads Bombina bombina and B. variegata. It is also an endogenous neurotransmitter in many animals including mammals. Bombesin affects vascular and other smooth muscle, gastric secretion, and renal circulation and function. Bombesin 14,Bombesin Dihydrochloride,Dihydrochloride, Bombesin
D003847 Deoxyglucose 2-Deoxy-D-arabino-hexose. An antimetabolite of glucose with antiviral activity. 2-Deoxy-D-glucose,2-Deoxyglucose,2-Desoxy-D-glucose,2 Deoxy D glucose,2 Deoxyglucose,2 Desoxy D glucose
D004285 Dogs The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065) Canis familiaris,Dog

D005753 Gastric Mucosa Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.

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
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
