OBJECTIVE To analyze the epidemiological profile of patients with gastroduodenal ulcer perforation and verify if the presence of H. pylori in the peritoneal and intraluminal secretions of these patients can be assessed by rapid urease test. METHODS We conducted a prospective, descriptive, cross-sectional study with data from patients in a hospital at a regional level, in patients with peptic ...

OBJECTIVE Helicobacter pylori (H. pylori) is the most common pathogenic bacteria in the stomach. The aim of the current study was to explore the effect of oral garlic administration on bacterial urease activity inside the stomach and its contribution to the treatment of H. pylori infection. MATERIALS AND METHODS In this clinical trial, 15 patients were studied quantitatively with Urease Breat...

INTRODUCTION The sensitivity of invasive diagnostic methods for Helicobacter pylori (H. pylori) infection, particularly of urease rapid test, is decreased in cases of gastroduodenal ulcer and upper gastrointestinal bleeding. OBJECTIVES To assess the influence of blood in the stomach or recent bleeding endoscopic signs in the diagnostic sensitivity of urease rapid test among patients with blee...

Detection of helicobacter pylori (H. pylori) by invasive methods is costy and unpleasant for patients and is not free form complication ,thus in our study we evaluated an enzyme linked immunosorbent assay (ELISA) for measurement of H. pylori specific IgG in saliva in comparison with biopsy urease test and serum IgG.from 100 patients consult gastrointestinal in Najaf Hospitals during the period ...

CONTEXT Multiple diagnostic methods are available for the detection of Helicobacter pylori infection, but at present no single one can be used as the gold standard. OBJECTIVE The aim of this study was to evaluate the diagnostic accuracy of 3 invasive and 2 non-invasive methods for detection of Helicobacter pylori infection in symptomatic children and adolescents. DESIGN Prospective cohort s...

BACKGROUND Helicobacter pylori affects gastric epithelium integrity by acceleration of apoptosis. However, it remains unclear what product of the bacteria causes apoptosis, or whether or not the apoptosis is involved in the development of ulcers. AIMS To elucidate the factor from H pylori that causes acceleration of apoptosis and the role of apoptosis in the development of duodenal ulcer in H...

Ubiquitous soybean urease, as opposed to the seed-specific urease, designates the seemingly identical ureolytic activities of suspension cultures and leaves. It also appears to be the basal urease in developing seeds of a variety, Itachi, which lacks the seed-specific urease (Polacco, Winkler 1984 Plant Physiol 74: 800-804). On native polyacrylamide gels the ureolytic activities in crude extrac...
