BACKGROUND Recently, it has been suggested that Helicobacter pylori might be a cause of some cases of infantile hypertrophic pyloric stenosis (IHPS) in infancy on the basis of its epidemiologic and clinical features. We performed this study to evaluate the possible relationship between IHPS and H. pylori. DESIGN In consecutive infants with IHPS, we performed upper gastrointestinal endoscopy w...

The aim of the study was to ascertain the existence of intestinal metaplasia in gastric mucosa of patients with gastric carcinoma coupled with H. pylori positive chronic atrophic gastritis and possible connection of IM with the development of gastric carcinoma. The paper presents prospective study that included 50 patients with gastric carcinoma and 50 patients with chronic atrophic H. pylori p...

AIMS To investigate the association of cagA positivity and non-opsonic neutrophil activation capacity in wild-type Helicobacter pylori strains with peptic ulcer disease or chronic gastritis only. METHODS Helicobacter pylori were isolated from antral biopsies of 53 consecutive patients with chronic antral gastritis, of whom 24 had peptic ulcer disease endoscopically. The presence of cagA, a ma...

Effects of zerumbone on chronic gastritis remain unclear. The purpose of this study was to investigate the mechanism of the protective effect of zerumbone on the treatment of chronic gastritis in rats. The animal models of chronic gastritis in rats were established, and the surface damage of gastric mucosa was observed by gross anatomy; the changes of gastric mucosal tissue and surface morpholo...

BACKGROUND Fourier transform infrared (FT-IR) spectroscopy is an effective tool for investigation of chemical changes at the molecular level. We previously demonstrated that FT-IR spectroscopy can reliably distinguish multiple types of carcinoma from healthy tissue. Because various stomach diseases are common, it is important to explore a noninvasive and rapid method to detect malignancy and ga...

BACKGROUND Atrophic body gastritis is considered the first important step in the histogenesis of gastric carcinoma, a multistep process starting from chronic gastritis and progressing through chronic atrophic gastritis, intestinal metaplasia, and dysplasia. Helicobacter pylori is involved in the induction of atrophic body gastritis, but documentation of H. pylori infection is difficult because ...

AIM To investigate the association of TNF polymorphisms with chronic atrophic gastritis (CAG) and gastric adenocarcinoma in Chinese Han patients. METHODS The TNFa-e 5 microsatellites and 3 RFLP sites were typed using PCR technique, followed by high-voltage denaturing PAGE with silver staining and restriction enzyme digestion respectively in specimens from 53 patients with CAG and 56 patients ...

There have been few studies of the associations of genetic polymorphisms with precancerous gastric lesions. We conducted a cross-sectional study to compare the prevalences of several genetic polymorphisms in 302 subjects with mild chronic atrophic gastritis with prevalences in 606 subjects with deep intestinal metaplasia or dysplasia. This stratified random sample of 908 subjects was selected a...

BACKGROUND Chronic gastritis is an inflammation of the stomach mucosa, which is considered its main etiological factor the Helicobacter pylori. AIM To observe the differences in patients with chronic gastritis as well as the presence and absence of H. pylori, to obtain a better understanding of the etiological factors, clinical, dietary and lifestyle habits and associated diseases. METHODS ...
