Intraluminal esophageal sphincter manometry in dogs immobilized with xylazine. 1979

E Rosin, and S P Galphin, and J M Bowen

The pressure in the pharyngoesophageal and the gastroesophageal sphincters in six normal dogs immobilized with xylazine was studied, using a single side hole catheter continuously perfused with distilled water by a compressed air pressure pump. Mean maximal resting pressures of the pharyngoesophageal and the gastroesophageal sphincters were 6 +/- 1.2 mm of Hg and 11 +/- 2.9 mm of Hg, respectively. The technique and results will enable better definition of esophageal sphincter abnormalities.

D010614	Pharynx	A funnel-shaped fibromuscular tube that conducts food to the ESOPHAGUS, and air to the LARYNX and LUNGS. It is located posterior to the NASAL CAVITY; ORAL CAVITY; and LARYNX, and extends from the SKULL BASE to the inferior border of the CRICOID CARTILAGE anteriorly and to the inferior border of the C6 vertebra posteriorly. It is divided into the NASOPHARYNX; OROPHARYNX; and HYPOPHARYNX (laryngopharynx).	Throat,Pharynxs,Throats
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
D004947	Esophagus	The muscular membranous segment between the PHARYNX and the STOMACH in the UPPER GASTROINTESTINAL TRACT.
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.
