conclusions these human-derived lab and bifidobacteria exhibited different mechanisms involved in pathogenic inhibition. therefore a combination of these probiotic strains could be a great promise and possibility for the development of probiotic products to effectively prevent and control food-borne infection in humans. background food-borne pathogens are among the most significant problems in ...

The effects of 1 and 4 micrograms/kg/h somatostatin on pentagastrin-stimulated gastric mucosal blood flow and acid secretion were investigated in 12 normal subjects and in 12 patients with cirrhosis of the liver. Each dose of somatostatin was given intravenously to six normal subjects and to six patients. Gastric mucosal blood flow was measured by the neutral red clearance of the stomach. Penta...

To determine the relationship between gastric secretion and gastric carcinoma, we investigated gastric acid secretion and the fasting serum levels of pepsinogen I and gastrin in 50 Japanese patients with early gastric carcinoma. After the histological and macroscopic type of carcinoma had been determined, results were compared with findings in 50 Japanese control subjects whose gastric mucosa w...

background: helicobacter pylori may cause many gastrointestinal problems in developing countries such as iran. we aimed to analyze the cost- effectiveness and cost- utility of the test-and-treat and empirical treatment strategies in managing helicobacter pylori infection.            methods: this was a markov based economic evaluation. effectiveness was defined as the symptoms free numbers and ...

The story of gastric acid secretion began with early ideas on gastric secretion (Spallanzani and de Réaumur, 17th century) and with first descriptions of food digestion (Dupuytren and Bichat, Beaumont, early 18th century), followed by proof that gastric juice contained acid (Prout, early 18th century). The research continued with first descriptions of gastric glands as the source of gastric aci...

Background: Not all patients with acid-related disorders receiving proton pump inhibitor (PP) treatment get adequate gastric pH control. The genetic variation of receptors, metabolic enzymes, and transporters are known to cause failures of therapies. We have conducted a study to evaluate the influence of gastric H+/K+-ATPase, CYP2C19, and ABCB1 polymorphisms on the pharmacokinetic and pharmacod...

In the study to be described confirmation of the findings of Giles, Clark, and Buchan (1968) that the presence of acid in the lower oesophagus may stimulate gastric secretion has been sought. Also the influence of hiatal repair on the response to acid has been examined. The presence of acid in the lower oesophagus stimulates gastric secretion in man. The response to acid perfusion is greater in...

This study examined the effects of eradication of Helicobacter pylori (H pylori) infection on gastric mucosal morphology and acid secretion. Sixteen H pylori positive patients with enlarged gastric body folds were divided into two groups: (a) patients with moderate enlargement (fold width: 6 to 10 mm, n = 8) and (b) patients with severe enlargement (> 10 mm, n = 8). After successful treatment, ...

Modern gastroenterology started in early 19(th) century with the identification by W. Prout of the inorganic (hydrochloric) acid in the stomach and continued through 20(th) century with the discoveries by I.P. Pavlov of neuro-reflex stimulation of gastric secretion for which he was awarded first Nobel Prize in 1904. When concept of nervism or complete neural control of all digestive functions r...
