Duodeno-gastric reflux has been studied in normal subjects and patients with duodenal and gastric ulceration during the responses to parenteral secretin and cholecystokinin-pancreozymin and to acidification of the small intestine. Reflux was absent or slight in normal subjects and most patients with duodenal ulcer but was appreciable in most patients with gastric ulcer. Duodeno-gastric regurgit...

Sarcina Ventriculi is a gram-positive organism, rarely encountered as human pathogen. It has been described in stomach specimens, often patients with delayed gastric emptying. The exact role of this organism disease not clear. In case report, we describe associated ulceration. This likely underreported and overlooked, it may be obvious on routine staining. Awareness further studies are needed t...

Protein malnutrition can adversely affect all tissues. The aim of the present study was to test the hypothesis that protein deprivation influences gastric ulcer formation, as well as metabolism and organ growth, in rats. In the present study, there was a significant reduction in the body and organ weight of rats fed a low-protein diet (P<0.001). Malnourished rats were less susceptible to ulcera...

Mucus was sampled from the gastric mucosal surface of anaesthetised rats. Three weeks later these rats were orally dosed each day with aspirin (375 mg/kg) for six months. Then the number and size of the aspirin induced chronic gastric ulcers were assessed. Gel filtration chromatography of the mucus samples showed that mucus glycoprotein was present in both high and low molecular weight forms. T...

Bezděková B., P. Jahn, M. Vyskočil: Gastric Ulceration, Appetite and Feeding Practices in Standardbred Racehorses in the Czech Republic. Acta Vet. Brno 2008, 77: 603-607. The objective of our study was to determine the prevalence of poor appetite and its correlation with the prevalence of gastric ulceration, and to evaluate relation between feeding management (feeding frequency and feeding regu...

This study evaluated the antiulcer activity of an ethanolic extract of Encholirium spectabile (ES-EtOH) by using different standard experimental models of induced acute gastric ulceration. ES-EtOH (100 mg/kg p.o) protected the gastric mucosa against ulceration that was induced by absolute ethanol (53%), ethanol/HCl (75%), ibuprofen (52 %) and ischemia/reperfusion (43 %). It also restored catala...

Background: There is extensive variety of chemical compounds with antiulcer activity, which are isolated from medicinal plants. Matricaria chamomilla or Matricaria recutita or German chamomile, also spelled chamomile (MC), is one of the most widely used medicinal plants. In the present study, the extract of MC flowers was evaluated for antiulcerogenic activity and acute toxicity profile. Method...

BACKGROUND & AIMS The peptic ulcer heals through a complex process, although the ulcer relapse often occurs several years later after healing. Our hypothesis is that even after visual evidence of healing of gastric ulceration, the regenerated epithelium is aberrant for an extended interval, increasing susceptibility of the regenerated epithelium to damage and further diseases. METHODS Gastric...

Biopsies from 56 patients with endoscopically normal duodenal bulbs, duodenitis, or duodenal ulceration were studied for counts of plasma cells, polymorphs, and eosinophils and extent of gastric metaplasia, villous atrophy, and mucosal oedema. A correlation matrix showed that the counts of different types of plasma cells were closely correlated with each other and that there was also a close co...
