چکیده باکتریhelicobacter pylori دارای خانواده ای از پروتئین های غشاء خارجی شامل 32 عضو است. چسبیدن با واسطه برخی از این پروتئین های غشاء خارجی سبب القای تولید اینترلوکین-8 می گردند. یکی از این پروتئین های غشاء خارجی، 33 -35 کیلو دالتون بوده و توسط ژن پروتئین التهابی غشائ خارجیa (oipa) بیان میگردد، که نقش مهمی را در بیماری زایی helicobacter pylori ایفا می نماید. .هدف ما از این مطالعه جداسازی و...
Background : Helicobacter pylori is a microorganism which results in gastritis, peptic ulcer and is associated with GI malignancies. This bacteria has an important role in GI disease .There is not enough data about prevalence of H.P infection among children (1-14 years old) in Lorestan province, so this study performed to determine the sero-prevalence of H.P among children referred to Shahid M...
Background and Aim: Gastrointestinal disease is one of the most common infectious diseases in the world. One of the most important causes is Helicobacter pylori infection. Considering the importance of this bacterium and its different prevalence in different parts of the country, this study was conducted to determine the prevalence of Helicobacter pylori infection and its related factors in 9-1...
Flavin-dependent enzymes are characterized by an amazing chemical versatility and play important roles in different cellular pathways. The FAD-containing choline oxidase from Arthrobacter globiformis oxidizes choline to glycine betaine and retains the intermediate betaine aldehyde in the active site. The reduced FAD is oxidized by oxygen. Glycine betaine is an important osmoprotectant accumulat...
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 & Objective: Helicobacter pylori is a bacterium responsible for one of the most prevalent infections found in humans worldwide. Considering the importance of this infection and its different prevalence in different regions of Iran, this study was conducted to determine the prevalence of Helicobacter pylori in Chahar Mahal and Bakhtiari as a high-risk province. Materials & Methods :...
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.
