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...

conclusions: the result of our study showed that using clarithromycin, amoxicillin and omeprazole for treatment of h. pylori infection can be useful. it is concluded from lower levels of igg and caga in blood and h. pylori antigen in stool after treatment compared to the amount of these factors before therapy. considering all these data, it is obvious that there is an urgent need to found a bet...

Although Helicobacter pylori has a significant impact on the occurrence of severe clinical syndromes, its exact ways of transmission and origin have not been identified. According to the results of some previously published articles, foods with animal origins play a substantial role in the transmission of H. pylori to humans. The present investigation was carried out to study the vacuolating cy...

Background: It has been reported that several species of Helicobacter colonize the biliary tract of animals and human, but their participation in hepatobiliary diseases are not established. This study is undertaken to determine if Helicobacter genus members, especially with regard to H. pylori, could be detected in the bile and gallbladder diseases. Methods: Thirty-eight gallbladder tissues and...

Helicobacter pylori (H. pylori) urease generates both ammonia (NH3) and carbon dioxide (CO2) from urea. NH3 helps H. to survive in the stomach part by neutralizing gastric acid. However, relationship between CO2 is not completed cleared. We examined effect of generated on multiplication using isogenic ureB mutant complemented strain JP26. Wild-type survived medium supplement with 1mM urea room ...

BACKGROUNDS/AIMS Chronic gastritis induced by Helicobacter pylori is characterised by considerable neutrophil infiltration into the gastric mucosa without mucosal invasion of bacteria. Bacteria have different characteristics with respect to their ability to stimulate human neutrophils to produce reactive oxygen species and chemokines. The aim of this study was to examine the effects of H pylori...

Background: Helicobacter pylori has caused gastritis leading to bleeding and iron deficiency anemia. H-pylori eradication results in better response oral treatment. Aim: To determine the frequency of improvement refractory anemia after successful H-pylori. Study design: Descriptive, case series. Methodology: Patients (n=89) anemia, 15-55 years either gender were included. After this taking rele...

Stomach cancer occupies a leading position in oncological morbidity and mortality worldwide. Approximately 800,000 people die from stomach every year. In two-thirds of patients gastric is diagnosed at late stage, when radical treatment becomes impossible. Helicobacter pylori (H. pylori) infection considered as the main etiological factor for cancer. To stratify risk developing an assessment mor...

Background Helicobacter pylori (H. pylori) is believed to be the most common bacterial infection worldwide. Herein, we aimed to investigate the effect of red rose extract on H. pylori eradication in 9 to 15 year-old children. Materials and Methods In this randomized controlled clinical trial,by the convenience sampling method...
