Abstract Background：The rapid urease test has been widely used for detection of Helicobacter pylori infection because it is easy, simple and rapid result. The CLO test and PyloriTek test observe color changes after the gastric biopsy specimens are inerted into the test kits. Because H. pylori is not evenly distributed in the gastric mucosa, grinding or mincing of gastric specimens prior to culture enhances isolation rate of H. pylori. Therefore, we evaluated the effects of rubbing the gastric biopsy specimens onto the urea soaked filter paper in this home-made rapid urease

Abstract Background: Helicobacter pylori (H. pylori) is closely associated with gastritis, peptic ulcer and gastric carcinoma. We evaluated the reliability and usefulness of ¹³C-urea breath test (¹³C-UBT) for the detection of H. pylori infection and searched for the cut-off value of the test. Method: We investigated 45 patients, who underwent esophagogastroduodenoscopy with multiple biopsy specimens taken for culture, histology and rapid urease test, and ¹³C-UBT. Sensitivity and specificity of UBT were calculated against the combined biopsy-based test results. Result: Of 45 patients, 26 were found to be H.

Abstract Background：Helicobacter pylori is the single most common pathogen that causes chronic bacterial infection in human. The authors designed a new type of urease detection method (Asan Helicobacter test) that can be used for rapid early detection of H. pylori as well as a transport medium. This medium has a strong acidity with a minimal concentration of urea for the purpose of the detection of H. pylori. The current study was to evaluate the

Abstract Background: The most commonly used regimen for the eradication of Helicobacter pylori is combination of a proton pump inhibitor, clarithromycin, and two other antibiotics, metronidazole and amoxicillin. The increase in resistance to antibiotics seems to result in a decrease in eradication efficacy for H. pylori. We investigated the prevalence of antibiotic resistance in H. pylori isolated in Daejeon area. Methods: A total of 31 clinical isolates of H. pylori were collected from the patients who underwent upper gastrointestinal endoscopy in Keonyang University Hospital during the period from
