The relationship between esophageal peristalsis and in vivo intraband pressure measurements in gastric banding patients.

Intraband pressure (IBP) measurement may be a less invasive method to assess esophageal motility response to band adjustment and restrictive integrity of the device in Swedish adjustable gastric band (SAGB) patients. However, the relationship between IBP and esophageal function is not yet established. Our aim was to characterize in vivo IBP-peristalsis associations in SAGB patients.

Effect of hydrochloric acid, pepsin, or taurocholate on bioelectric properties of gastric squamous mucosa in horses.

Objective: To determine the effect of pH with or without pepsin or taurocholic acid on the bioelectric properties of gastric squamous mucosa in horses.

Sample Population: Gastric tissues obtained from 16 adult horses that did not have evidence of gastric disease.

Procedure: Bioelectric properties of squamous mucosa were determined, using modified Ussing chambers.
