The mechanical breakdown and mixing of food occurs in the stomach and reduces meals into smaller particle size that can pass into the small intestine. The lining of the equine stomach is divided into an upper squamous mucosa (non-glandular) and the lower glandular mucosa. The squamous mucosa does not absorb or secrete anything, but has the primary role of aiding the mechanical breakdown of inge...

We report a case of gastric adenomyoma contiguous with adenocarcinoma of the stomach. Although a similar association is well recognized in the duodenum, we believe this to be the first documented case in the stomach. We review the literature on adenomyomata and discuss the implications of this finding. It would appear that glandular and cystic intramural lesions of the stomach are a heterogeneo...

BACKGROUND: In preclinical studies on laboratory animals, oral administration with special probe for test substances is very in demand. Most are devoted to the psychophysiological and clinical-biochemical reaction of animals body this effect, but extremely few consider effect manipulation itself development pathology tissues gastrointestinal tract associated inevitable mechanical impact mucous ...

The endogenous noradrenaline concentration, fractional turnover, half-life, and turnover rate of tritiated ((3)H) noradrenaline were determined in the oesophagus, non-glandular and glandular portions of the stomach, duodenum, jejunum, ileum, and colon of the rat. The highest concentration of endogenous noradrenaline was present in the duodenum and colon. The (3)H-noradrenaline fractional turnov...

Magnifying endoscopy with narrow-band imaging (M-NBI) can visualize superficial microanatomies in the stomach. The normal morphology of the microanatomy visualized by M-NBI differs according to the part of the stomach. The gastric fundic glandular mucosa appears as a regular honeycomb-like subepithelial capillary network (SECN) pattern with a regular collecting venule pattern and regular oval c...

Background This study aimed to evaluate the effects of the position of an acetic acid-induced gastric ulcer and the effects of prokinetic drugs on gastric emptying. Materials and Methods Male Sprague-Dawley rats were used in this study. Acetic acid ulcers were induced either in the region between the fundus and pylorus on the anterior wall of the stomach or in the glandular region on the greate...

Gastric ulcers are common in horses, with a prevalence estimated from 53 to 93%.1-3 Gastric ulcers can lead to decreased performance, vague clinical signs and may go undiagnosed for months. Gastric ulcers are primarily caused by stomach acids. However, the anatomy of the stomach, diet, restricted feed intake, exercise, stress (stall or transport), and the use of non-steroidal anti-inflammatory ...
