Since antiquity, medical herbs have been prescribed for both treatment and preventative purposes. Herbal formulas are used to reduce toxicity as well as increase efficacy in traditional Korean medicine. U-bang-haequi tang (UBT) is a herbal prescription containing Arctii fructus and Forsythia suspensa as its main components and has treated many human diseases in traditional Korean medicine. This...

AIM To quantitatively summarize and appraise the available evidence of urea breath test (UBT) use to diagnose Helicobacter pylori (H. pylori) infection in patients with dyspepsia and provide pooled diagnostic accuracy measures. METHODS We searched MEDLINE, EMBASE, Cochrane library and other databases for studies addressing the value of UBT in the diagnosis of H. pylori infection. We included ...

AIM To compare (1) demographics in urea breath test (UBT) vs endoscopy patients; and (2) the molecular detection of antibiotic resistance in stool vs biopsy samples. METHODS Six hundred and sixteen adult patients undergoing endoscopy or a UBT were prospectively recruited to the study. The GenoType HelicoDR assay was used to detect Helicobacter pylori (H. pylori) and antibiotic resistance usin...

BACKGROUND The treatment failure rate for Helicobacter pylori eradication therapy is ~20% due to poor patient compliance and increased antibiotic resistance. This analysis assessed the cost-effectiveness of universal post-treatment testing to confirm eradication of H. pylori infection in adults. METHODS Decision-analytic models evaluated the cost-effectiveness of universal post-treatment test...

The 13/14C-Urea breath test (UBT) is based on the simple principle that a solution of isotopically labelled urea will be rapidly hydrolysed by the abundantly expressed urease of H pylori. The released 13/14CO2 is absorbed across the mucus layer to the gastric mucosa and hence, via the systemic circulation, excreted in the expired breath. Distribution of urea throughout the stomach prevents samp...

Forage grass nutritional quality directly affects animal feed intake, productivity, and enteric methane (CH 4 ) emissions. This study evaluated the quality, in vitro CH emission potential, optimization of diets based on two widely grown tropical forage grasses either alone or mixed with legumes. The Urochloa hybrid cv. Cayman (UHC) U. brizantha Toledo (UBT), which typically have low concentrati...

The longitudinal stability of the urea breath test (UBT), which measures urease as a biomarker for infection with Helicobacter pylori (a major risk factor for gastric cancer), was evaluated in the environs of Tsukuba, Japan. 13C-UBT measurements were monitored at four time points in 46 free-living, H. pylori-infected, asymptomatic volunteers over a period of 7 weeks. Subjects were asked to refr...

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...

Received July 10, 2002 Abstract Urea breath test (C-UBT) is a non-invasive diagnostic test for Helicobacter pylori infection. A preliminary retrospective study was conducted in the use of C-UBT in paediatric patients in Hong Kong. The study was conducted in Kwong Wah Hospital, a regional public hospital in urban Hong Kong. Eight asymptomatic paediatric patients who underwent C-UBT were analyzed...

The urea breath test UBT C13,14 is a good rapid diagnostic procedure used to identify stomach infections by H. pylori. It is based upon the ability of H. pylori to convert urea to ammonia and carbon dioxide. Urea breath tests are recommended in leading society guidelines as a preferred non-invasive choice for detecting H. pylori of stomach before and after treatment with diagnostic efficacy at ...
