Correlation between13C-urea breath test value and severity of gastric mucosal lesions

The urea breath test for Helicobacter pylori.

Low dose capsule based 13c-urea breath test compared with the conventional 13c-urea breath test and invasive tests.

CONTEXT One of the limitations of 13C-urea breath test for Helicobacter pylori infection diagnosis in Brazil is the substrate acquisition in capsule presentation. OBJECTIVES The purpose of this study was to evaluate a capsule-based 13C-urea, manipulated by the Pharmacy Division, for the clinical practice. METHODS Fifty patients underwent the conventional and the capsule breath test. Samples...

Protective Effect of Crocin on Gastric Mucosal Lesions Induced by Ischemia-Reperfusion Injury in Rats

The present study aimed to evaluate the protective effect of crocin on gastric mucosal lesions caused by ischemia-reperfusion (I/R) injury in rats.Forty male rats were randomly divided into sham, control (I/R injury) and three crocin-pretreated groups. To induce I/R lesions, the celiac artery was clamped for 30 min and then the clamp was removed to allow reperfusion for 3 h. Pretreated-rats rec...

Gastric mucosal density of Helicobacter pylori estimated by real-time PCR compared with results of urea breath test and histological grading.

The accuracy of the urea breath test (UBT) and histological grading for estimation of the density of Helicobacter pylori in gastric mucosa is not known. Real-time (TaqMan) PCR was used to estimate the total number of H. pylori genomes in biopsy samples. These values were compared with those obtained by the UBT and the histological grade obtained by the Sydney system. The UBT and endoscopy with ...
