Effect of ginger on lower esophageal sphincter pressure.

OBJECTIVE Ginger has been traditionally used to reduce intestinal gas and flatulence. The present study examined the effects of ginger on the esophagus and lower esophageal sphincter (LES) function by esophageal manometry. STUDY DESIGN A randomized controlled trial. SETTING Departments of Physiology and Medicine, Faculty of Medicine Siriraj Hospital. SUBJECTS Fourteen healthy young male v...

Lower esophageal sphincter pressure measurement under standardized inspiratory maneuveurs.

BACKGROUND Through rhythmic variations, the diaphragm influence lower esophageal sphincter (LES) pressure acting as an external sphincter. LES pressure recording is characterized by increased pressure in inspiration due to contraction of the diaphragmatic crura that involves the sphincter. AIM To describe a method of measuring LES pressure during standardized inspiratory maneuvers with increa...

Mechanics of sphincter action. Studies on the lower esophageal sphincter.

The purpose of this study was to evaluate the mechanical factors involved in the genesis of lower esophageal sphincter pressure. We determined the relationship between intraluminal pressure and inside diameter, estimated the ratio between the wall thickness to inside radius, and calculated the tension in the wall of the lower esophageal sphincter as a function of the inside diameter. Various de...

Hormonal regulation of human lower esophageal sphincter competence: interaction of gastrin and secretin.

The interaction of gastrin and secretin, in the regulation of human lower esophageal sphincter competence, was studied in 54 normal subjects. A dose-response curve, for the lower esophageal sphincter, was constructed from the rapid intravenous injections of synthetic gastrin I (amino acid sequence 2-17). This curve was sigmoid shaped and showed a peak response that was 460.0 +/-24.0% (mean +/-2...

Pharmacologic identification of the lower esophageal sphincter.

The distal 2/3 of the opossum esophagus contains only smooth muscle. Manometry shows that the most distal 1-2 cm is the lower esophageal sphincter. We used a variety of agonists to seek differences between circular muscle from the sphincteric segment and more rostral levels. Isometric contractions of strips from the distal 6 cm were recorded in vitro in response to acetylcholine, carbachol, met...
