BACKGROUND The purpose of this study is to compare validity of 5 diagnostic tests of helicobacter pylori with each other: stool antigen test, urea breath test (UBT), rapid urease test (RUT), serology and histology. METHODS A total of 94 patients who had indication of endoscopy entered the study. All of the 5 tests were performed for each patient. When the results of at least 2 tests were posi...

OBJECTIVES To determine the efficacy of a simple, short-term and low-cost eradication treatment for Helicobacter pylori (H. pylori) using omeprazole, tetracycline, and furazolidone in a Brazilian peptic ulcer population, divided into 2 subgroups: untreated and previously treated for the infection. PATIENTS AND METHODS Patients with peptic ulcer disease diagnosed by endoscopic examination and ...

Exposure of macrophages to asbestos fibers resulted in enhancement of the production of oxygen radicals, determined by a lucigenin enhanced chemiluminescence (LEC) assay, a formation of thiobarbituric acid reactive substances (TBARS), a LDH release into the incubation mixture, and a rapid lysis of the cells. Rutin (Rut) and quercetin (Qr) were effective in inhibiting LEC, TBARS formation, and r...

Background. We encountered repeatedly, in our clinical practice, discordant results between UBT and histopathology about H. pylori infection. Goal. To study the diagnostic accuracy of Heliprobe (14)C-urea breath test ((14)C-UBT) for detection of H. pylori infection in an Iranian population. Study. We enrolled 125 dyspeptic patients in our study. All of them underwent gastroscopy, and four gastr...

BACKGROUND To investigate any possible relationship between serum leptin level and H.pylori infection in dyspeptic Iranian adults. METHODS A total of 153 dyspeptic patients referring to Firoozgar hospital for esophagogastroduodenoscopywere enrolled in the study. Serum leptin level was measuredbefore endoscopy, after overnight fasting. Two biopsy specimens weretaken from antrum for each patien...

A new 1:1 molecular complex of triterpene glycoside ammonium glycyrrhizate (GC) with flavonoid rutin (Rut) was obtained in aqueous ethanol. The stability constant (9.7±0.2)×104 (mol/L)–1 calculated for the via isomolar curves. complexation studied by UV- and ATR IR-Fourier spectroscopy a method series. hydrogen bonds hydrophobic interactions are formed complex. preliminary antioxidant activity ...

background helicobacter pylori diagnostic tests can be affected by different interventional factors. we studied the effects of smoking, proton pump inhibitors (ppis) and antibiotic administration on results of the bacterial culture, and its diagnosis tests due to polymerase chain reaction (pcr) and rapid urease test (rut) methods. objectives this study was aimed to investigate the undesirable e...

Retrograde signaling is an essential component of synaptic development and physiology. Previous studies show that bone morphogenetic protein (BMP)-dependent retrograde signaling is required for the proper development of the neuromuscular junction (NMJ) in Drosophila. These studies, moreover, raised the significant possibility that the development of central motor circuitry might similarly be re...

BACKGROUND Decreased density of H. pylori in atrophic gastritis may lead to low sensitivity of the routine tests. AIMS To evaluate the accuracy of routinely used H. pylori tests in atrophic gastritis. METHODS We compared 5 H. pylori diagnostic tests in 119 dyspeptic patients (28 males/91 females) with a mean age of 67 years (range 55-84). Patients with gastric cancer, peptic ulcer, previous...
