animal models for h.pylori infection have been developed to clarify the pathogenesis, testing new therapies and developing vaccines against human h.pylori infection. although rats have been used extensively for gastric ulceration and acid secretion studies, the animal is not normally infected with h.pylori.several chemicals such as ethanol and ammonium hydroxide can induce gastric erosion and i...
The role of glucocorticoids released in response to stress in the pathogenesis of stress-induced gastric erosions has been reevaluated. Gastric erosions elicited in male rats by 3-h cold-restraint or water-restraint stresses were studied after acute reduction of corticosterone release or occupation of glucocorticoid receptors by the antagonist RU-38486 during stress. Stress-induced corticostero...
Bilateral infusions of N-methyl-D-aspartate (NMDA) into the lateral hypothalamus (LH) produce gastric erosions in rats. The present study attempted to determine the neural pathways that mediate this effect. In order to interrupt axonal transmission, knife cuts (KC) were made in different planes adjacent to the LH. In separate groups of rats, KC were made anterior, posterior or lateral to the LH...
BACKGROUND To analyze risk factors associated with gastro-duodenal ulcers and erosions in children. METHODS Open, prospective, multicenter, case-control study carried out in 11 European countries in patients with gastric or duodenal ulcers/erosions and 2 age-matched controls each. Possible risk factors were recorded. Logistic regression models were performed with adjustment for centers and ag...
Considerable progress has been made in the understanding of the formation of gastric erosions by the use of animals. The role of gastric acid secretion in their pathogenesis has been clarified. Gastric erosions are associated with the presence of acid in the stomach and slow gastric contractions. With several different experimental procedures, the animal's body temperature falls; preventing the...
SYNOPSIS An analysis of the 149 cases of haematemesis admitted to Coronation Hospital from January 1951, to September 1959, is presented. The commonest cause was found to be acute gastritis and gastric erosion. These cases were more common in males and usually followed on an alcoholic bout. These were in the main mild. Twenty-five cases associated with peptic ulceration were found, and the lesi...
Introduction: The incidence rate of gastric erosions and ulcers in diabetic patients are higher due to failure of mucosal antioxidant defense and maintain enough blood flow. The present study evaluated the gastro-protective effect of sodium hydrosulfide (NaHS) against indomethacin-induced gastric lesions in diabetic rats. Methods: In order to test anti-ulcer activity of NaHS against indomet...
Gastrointestinal disturbances like anorexia, nausea, vomiting, abdominal discomfort and diarrhoea are known adverse effects of rifampicin. We report an upper gastrointestinal bleeding due to haemorrhagic gastric erosions after ingestion of rifampicin for pulmonary tuberculosis. The cause and effect relationship between development of haemorrhagic gastric erosions and rifampicin administration w...
