A new endoscopic classification system of early-stage esophageal carcinoma and its usefulness in assessing the infiltration depth of esophageal carcinoma.

The growth pattern, height, and depth of early esophageal carcinoma were observed under gastroscopy and endoscopic ultrasonography. The infiltration depth of carcinomas was determined pathologically. Early esophageal carcinomas were classified into five types by endoscopy: surface propagating growth, intraluminal growth, intramural growth, bilateral growth, and mixed growth.

Effects of surface gastric pacing on gastric myoelectrical activity and plasma motilin in a canine model of gastric motility disorders.

Objective: To investigate the effects of surface gastric pacing on gastric myoelectrical activity and plasma motilin concentration in a canine model of gastric motility disorders.

Methods: Ten healthy mongrel dogs were divided into two groups: an experimental group of six dogs and control group of four dogs. The model of gastric motility disorders was established in the experimental group with truncal vagotomy combined with injection of glucagon.

Gastro-electric dysrhythm and lack of gastric interstitial cells of cajal.

Aim: The pathophysiology underlying gastrointestinal complications of long-standing diabetes is poorly understood. Recent evidence suggests an important role of intestitial cells of cajal in controlling gastrointestinal motility. The aim of this study was to clarify the changes of ultrastructural characteristics of interstitial cells of cajal in stomach of diabetic gastro-electric dysrhythmic rats.

Effects of gastric pacing on gastric emptying and plasma motilin.

Aim: To investigate the effects of gastric pacing on gastric emptying and plasma motilin level in a canine model of gastric motility disorders and the correlation between gastric emptying and plasma motilin level.

Methods: Ten healthy Mongrel dogs were divided into: experimental group of six dogs and control group of four dogs. A model of gastric motility disorders was established in the experimental group undergone truncal vagotomy combined with injection of glucagon.
