The oesophagus lined with gastric mucous membrane.
Peptic oesophagitis and peptic ulceration of the squamous epithelium of the oesophagus are secondary to regurgitation of digestive juices, are most commonly found in those patients where the competence ofthe cardia has been lost through herniation of the stomach into the mediastinum, and have been aptly named by Barrett (1950) " reflux oesophagitis." In the past there has been some discussion a...
متن کاملGrowth cycle of Helicobacter pylori in gastric mucous layer.
Helicobacter pylori bacterium is characterized by its strong urease activity. Our studies on the role of H. pylori urease revealed; (i) it is essential for colonization, (ii) exogenous urea is required for acid resistance, (iii) the bacteria have the ability to move toward urea and sodium bicarbonate, (iv) urea hydrolysis accelerates chemotactic locomotion, and (v) decay of urease mRNA to accom...
متن کاملGastric mucous neck cell and intestinal goblet cell phenotypes in gastric adenocarcinoma.
AIM To investigate the phenotype of cells comprising diffuse and intestinal-type gastric cancers using monoclonal antibodies to two antigens. One antigen (designated D10) is characteristic of gastric mucous neck cells, cardiac glands, pyloric glands, and Brunner's glands. The second antigen (designated 17NM) is specific to the mucous vacuole of intestinal goblet cells. METHODS Thirty two gast...
متن کاملHelicobacter pylori and two ultrastructurally distinct layers of gastric mucous cell mucins in the surface mucous gel layer.
BACKGROUND AND AIMS Helicobacter pylori locate not only on the apical surface of surface mucous cells but also in the mucous gel layer covering the gastric mucosa. The present study was undertaken to observe the mucous gel layer itself and any H pylori in this layer at the electron microscopic level, and to determine whether H pylori proliferate in this layer. METHODS We examined resected hum...
متن کاملhistochemical study of mucous substance of gastric epithelial lesions
introduction: mucinous compounds are a group of neutral glycoprotein which have a prime effect for protection of surface epithelium against digestion. studies showed the changes of these compounds in neoplasia and intestinal metaplasia of the stomach. materials and methods: specimens were taken from 25 surgically resected stomach from gastric lesion and it's periphery and processed as routine i...
