In dogs with fistulas in fundal and antral parts of the stomach and in the proximal part of jejunum, subcutaneous and i.v. administration of pentagastrin and i.v. administration of cholecystokinin caused reciprocal reactions in the stomach: pentagastrin suppressed the motility of fundal part and activated the contractions of antral part, whereas cholecystokinin activated the contractions of fundal part and suppressed the motility of antral part of the stomach. Excepting a more complex character of pentagastrin and cholecystokinin effects on the jejunum contractions, the responses were reciprocal as well. Pentagastrin exerts mainly a suppressing effect whereas cholecystokinin--an activating one. Possible biological significance of the hormones interactions while maintaining evacuatory function of the stomach, is discussed.

UI MeSH Term Description Entries
D008365 Manometry Measurement of the pressure or tension of liquids or gases with a manometer. Tonometry,Manometries
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
D002766 Cholecystokinin A peptide, of about 33 amino acids, secreted by the upper INTESTINAL MUCOSA and also found in the central nervous system. It causes gallbladder contraction, release of pancreatic exocrine (or digestive) enzymes, and affects other gastrointestinal functions. Cholecystokinin may be the mediator of satiety. Pancreozymin,CCK-33,Cholecystokinin 33,Uropancreozymin
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
