......................................... Received: 05-12-11 Accepted: 15-05-12 Abstract Gastritis is an inflammation of the lining of the gastric mucosa which occurs in response to an injury. It can be acute, chronic or mixed, and it can be associated with intestinal metaplasia and atrophy. There are multiple etiologic factors including irritation, chemical, immunological, genetic and infectio...

  Background and Objective: Long period risk of gastric carcinoma in people affected with chronic Helicobacter pylori gastritis is 5 times more than normal people. Perhaps histological changes due to helicobacter pylori infection could be used for screening people at risk of gastric carcinoma and peptic ulcer. Materials and Methods: This study has been carried out as a cross...

AIM To evaluate the association between Helicobacter pylori (H. pylori) infection and MLH1 and MGMT methylation and its relationship with microsatellite instability (MSI). METHODS The methylation status of the MLH1 and MGMT promoter region was analysed by methylation specific methylation-polymerase chain reaction (MSP-PCR) in gastric biopsy samples from uninfected or H. pylori-infected childr...

BACKGROUND The association between proinflammatory cytokine gene polymorphisms and gastric diseases related to Helicobacter pylori varies by population and geographic area.Our objective was to determine if the IL-1B -511 T>C and -31 C>T polymorphisms and H. pylori vacA genotypes are associated with risk of chronic gastritis and gastric ulcer in a Mexican population. METHODS We conducted endos...

helicobacter pylori (h. pylori) infection has been reported in more than half of the world human population. it is associated with gastric inflammation and noticeable infiltration of the immune cells to the stomach mucosa by several cytokines secretion. il-1β, il-18 have been shown to contribute to h. pylori induced gastritis, but the details of inflammation and association of virulence factors...

First described in 1998, Russell body gastritis is a rare chronic inflammatory condition characterized by abundant intramucosal polyclonal plasma cells, which contain intracytoplasmic eosinophilic globules of immunoglobulins (Russell bodies) that displace the nucleus, with an accompanying chronic inflammatory infiltrate. Russell bodies represent a cellular response to overstimulation of plasma ...

UNLABELLED Backgroud: Helicobacter pylori (Hp) rarely proliferates in patients with fundic gland polyps (FGPs). We recently found that FGPs express lysozyme, one of the natural defence substances against infection. We aimed to assess the degree of lysozyme expression in a cohort of consecutive FGPs. MATERIALS AND METHODS A total of 153 gastric biopsies were investigated: 93 with FGPs, 30 with...

Patients with osteoarthritis were entered into a single-blind trial comparing the effects on the gastric mucosa of a four week course of indomethacin, sulindac and a compound of paracetamol and dextropropoxyphene (Distalgesic). The presence and severity of both acute and chronic gastritis were assessed by histological examination of endoscopic biopsy specimens taken from five standard sites in ...

INTRODUCTION Helicobacter pylori (H. pylori) infection is known to be the must common cause of chronic gastritis having some endoscopic and pathologic characteristies as determinated by the Sydney System for Gastritis Classification. The aim of our case report was to point out the relationship between an endoscopic finding of nodular antritis and the presence of H. pylori infection and active c...
