• mucosal
  • AIM: To determine associations between enterogastric bile reflux and gastric mucosal pathology. (bmj.com)
  • Because, in other tissues, VEGF is one of the most potent angiogenic factors and VEGF expression is dependent on Ras, our data indicate that Ras and VEGF are involved in gastric mucosal angiogenesis after ethanol injury. (physiology.org)
  • Endothelial cells lining gastric mucosal microvessels are major and early targets of acute injury by ethanol ( 34 , 37 , 41 ). (physiology.org)
  • antral
  • METHOD: A retrospective study using fasting gastric juice bile acid measurements and antral or prestomal biopsy specimens from 350 patients, 66 of whom had previously undergone surgery that either bypassed or disrupted the pyloric sphincter. (bmj.com)
  • It was not possible to demonstrate any correlation between the labelling indices in antral and fundic mucosa. (bmj.com)
  • proliferation
  • The present study was aimed to determine whether vascular endothelial growth factor (VEGF) (a potent angiogenic peptide selectively acting on endothelial cells) and Ras (a mediator of cell proliferation and a putative regulator of VEGF expression) are involved in gastric angiogenesis after ethanol injury. (physiology.org)
  • rats
  • Gastric tissue was subjected to indirect double immunofluorescence staining with antiserum against the C-terminal decapeptide of the CCK2 receptor and antibodies against 5' bromo-2-deoxyuridine, which had been injected into the rats I h before they were killed, the acid pump H,K-ATPase, the membrane-cytoskeletal linker ezrin, pepsin/pepsinogen or histidine decarboxylase.

  • MALT
  • Endoscopy is key to diagnosing MALT lymphoma, with multiple biopsies of the visible lesions required, as well as samples of macroscopically normal tissue, termed gastric mapping. (wikipedia.org)

  • proteins
  • Ethanol damage triggered 1 ) angiogenesis in the gastric mucosa bordering necrosis, 2 ) significant increases in VEGF mRNA and protein expression, and 3 ) significant increases in the expression of Ki- ras mRNA and Ras proteins. (physiology.org)
  • They are stable secretory proteins expressed in gastrointestinal mucosa. (wikipedia.org)

  • White light endoscopic images (upper) and magnified endoscopic images (lower) (a) Magnified endoscopic image before treatment showing disappearance of the normal gastric pit pattern and appearance of irregular abnormal vessels (arrows). (hkmj.org)
  • cells
  • Mast cells are present in most tissues characteristically surrounding blood vessels and nerves, and are especially prominent near the boundaries between the outside world and the internal milieu, such as the skin, mucosa of the lungs, and digestive tract, as well as the mouth, conjunctiva, and nose. (wikipedia.org)
  • Expression
  • We studied the angiogenic response and expression of VEGF and Ras in gastric mucosa after ethanol injury. (physiology.org)
  • We have previously demonstrated, in a preliminary study, that ethanol-induced injury triggers the angiogenic response in the gastric mucosa bordering necrosis and also activates expression of bFGF and its receptors in this area ( 36 ). (physiology.org)
  • response
  • Endoscopy performed 6 weeks after completion of radiotherapy showed complete response, ie, recovery of gastric pit pattern under ME ( Fig 1b ). (hkmj.org)
  • Our previous studies demonstrated that ethanol injury triggers the angiogenic response in gastric mucosa bordering necrosis. (physiology.org)
  • evidence
  • These observations provide additional evidence in favour of a 'mucus-bicarbonate' barrier which may be of importance in protecting the underlying gastric mucosa. (bmj.com)
  • disease
  • It provides local control and potential cure in localized gastric stage IE and II 1E disease with 5-year EFS of 85-100% reported in retrospective studies. (wikipedia.org)
  • He suggests these organisms might be involved with gastric disease. (wikipedia.org)
  • essential
  • blood flow through microvessels, i.e., capillaries, arterioles, and collecting venules, is essential for supplying the gastric mucosa with oxygen and nutrients as well as for the removal of toxic metabolic products ( 16 ). (physiology.org)
