title: Response of lower esophageal sphincter pressure to beef soup or AOC-tetrapeptide stimulation in esophagitis.
abstract: In this study is intended a measurement of the pressure of the lower esophageal sphincter (LES) in resting state and after various stimuli such as beef soup and AOC-tetrapeptide in cases of healthy subjects and various diseases by means of an infused open-tip method. The following results were obtained: In the cases of esophagitis, the resting LES pressure is lower than in the cases of healthy subjects and after stimulation by beef soup or tetrapeptide the LES pressure is less elevated. Based on these observations, we concluded that there are some factors other than gastrin which make the LES pressure in the cases of esophagitis lower than in controls.
