Inhibition of bombesin-stimulated gastric acid secretion by secretin, glucagon and caerulein in patients with duodenal ulcer. 1979

I Kisfalvi

The inhibitory effects of intravenous infusions of secretin, glucagon and caerulein on the gastric acid response to bombesin were studied in 8 duodenal ulcer patients. Bombesin was found to be a very potent stimulator of gastric acid secretion in patients with duodenal ulcer. There were no significant differences in acid outputs per 15-min period between bombesin infused in a dose of 0.9 microgram/kg/h and pentagastrin infusion administered in a maximal dose, at a rate of 6.0 microgram/kg/h. Secretin (1 U/kg/h), glucagon (30 microgram/kg/h) and caerulein (0.1 microgram/kg/h) produced significant decreases in gastric acid secretion evoked by bombesin given in a dose of 0.9 microgram/kg/h. Percentages of inhibition were 48.6, 45.2 and 35.5, respectively. It is supposed that secretin and glucagon given in pharmacological doses are capable of interfering with the action of gastrin released from antrum by means of bombesin on the parietal cell by noncompetitive kinetics. Caerulein administered in a pharmacological dosis, however, can inhibit the effect of gastrin released by bombesin on the parietal cells by a competitive kinetic.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
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
D010455	Peptides	Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS.	Peptide,Polypeptide,Polypeptides
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
D002108	Ceruletide	A specific decapeptide obtained from the skin of Hila caerulea, an Australian amphibian. Caerulein is similar in action and composition to CHOLECYSTOKININ. It stimulates gastric, biliary, and pancreatic secretion; and certain smooth muscle. It is used in paralytic ileus and as diagnostic aid in pancreatic malfunction.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

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).

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.
