Phenylbutazone in moderate dosage has been administered to 15 patients with a variety of musculo-skeletal disorders. A rise in plasma pepsinogen activity occurred in 13, generally reaching a peak in the first week of treatment; subsequently there was a fall in spite of maintaining a constant dosage. In four of six patients an anticholinergic drug failed to prevent a rise in plasma pepsinogen ac...
The relation between Helicobacter pylori (H pylori) infection and fasting gastrin and pepsinogen-I and -II concentrations was evaluated in 278 volunteers without symptoms and the results were compared with the values obtained in 35 patients with duodenal ulcers. H pylori infection was determined with the 13C-urea breath test in subjects without symptoms and with endoscopy, biopsy (histology and...
BACKGROUND/AIM Individuals negative for Helicbacter pylori antibody and with a normal pepsinogen test (group A) are regarded as being at low risk in serum gastric cancer screening known as the ABC method, and endoscopy is not recommended; however, this group may include 2-10% of gastric cancer cases. PATIENTS AND METHODS A total of 345 individuals who underwent upper gastrointestinal endoscop...
BACKGROUND Atrophic gastritis is a precancerous condition, which can be diagnosed by several methods. However, there is no consensus for the standard method. The aim of this study was to evaluate the correlations among endoscopic, histologic, and serologic findings for the diagnosis of atrophic gastritis. METHODS From March 2003 to August 2013, a total of 2,558 subjects were enrolled. Endosco...
Objective: This study aims to investigate the clinical significance of gastrin 17 and pepsinogen in gastric cancer and precancerous lesion screening. Methods: We used ELISA to measure the levels of gastrin 17 and pepsinogen in serum from the medical examination population, which compared to endoscopic results. Then statistical analysis was performed. Results: The classical method by testing pep...
As the first step in the investigation of the structure and action of little known gastric zymogens and enzymes, pepsinogen has been isolated from the mucosa of the fourth stomach (abomasum) of the’ cow. The pepsinogen was purified by ammonium sulfate fractionation, batch absorption on diethylaminoethyl (DEAE) cellulose, recycling gel filtration on Sephadex G-100, and finally chromatography on ...
