introduction: the aim of this study is to investigate the effect of one nitric oxide inhibitor on the thickness and number of circular smooth muscle cells of pylor in rat embryo. material and methods: to determine the influence of nitric oxide reduction on the muscular layer of pylor in rat embryo, in the present study, pregnant sprague-dawley rats received the no synthase inhibitor n-nitro-l-a...

The aim of this study was to determine the prevalence and identify the species of gastric Helicobacter in the stool of dogs with gastritis. The study was carried out on thirty dogs of different breeds, of both genders and of various ages, diagnosed with gastritis. Helicobacter spp. was detected in stool samples using the nested-PCR method. Helicobacter bacteria were identified in stool samples ...

Infection with Helicobacter spp. is increasingly linked with hepatobiliary inflammation and neoplasia in people and in a variety of animals. We sought to determine if Helicobacter species infection is associated with cholangiohepatitis in cats. Deoxyribonucleic acid was extracted from tissue blocks from cats with cholangiohepatitis (32), noninflammatory liver disease (13), and cats with normal ...

In order to improve simultaneous detection and identification of Helicobacter genus in general and Helicobacter pylori specifically and reduce the number of amplifications needed, we established a multiplex PCR. In this study, two pairs of primers: Hcom1 and Hcom2 specific for Helicobacter genus, Hicd1 and Hicd2 specific for Helicobacter pylori species were used. To determine the sensitivity of...

BACKGROUND The lipopolysaccharide of Helicobacter pylori plays an important role in colonization and pathogenicity. The present study sought to compare structural and biological features of lipopolysaccharides from gastric and enterohepatic Helicobacter spp. not previously characterized. MATERIALS AND METHODS Purified lipopolysaccharides from four gastric Helicobacter spp. (H. pylori, Helicob...

effect of helicobacter pylori eradication or of ranitidine plus metoclopramide on helicobacter pylori-positive and of bismuth or ranitidine plus metoclopramide on helicobacter pylori-negative functional dyspepsia. a  randomized, controlled follow-up study.

Prevalence of Helicobacter is mostly unknown in laboratory animals in Thailand. The 221 mice feces/cecum from 8 universities, 2 pharmaceutical companies and 3 research institutions in Thailand were surveyed for the prevalence and distribution of Helicobacter species by using the Electrochemical DNA chip. Helicobacter were detected 23/46 samples in Specific Pathogen Free (SPF) and 168/175 in con...

Background: Polymorphisms in the immune related genes are important in the clinical outcome of Helicobacter pylori infection. Myeloperoxidase -463 G/A polymorphism has been shown to reduce enzyme expression and activity. Objective: the aim of the present study is to investigate the association of myeloperoxidase G-463A polymor-phism with clinical outcome of Helicobacter pylori infection. Method...
