Concentrations of serum pepsinogens (PG) I and II were determined for 3252 randomly selected adults who participated in a population-based gastroscopic screening in an area of China with one of the world’s highest rates of gastric cancer. PG I and II concentrations in both sexes tended to be higher than reported in other countries, with levels generally higher among males than females. PG I ten...
What is the trend in the incidence and death from gastric cancer in the Japanese population? How does this compare to the age standarized incidence rate of gastric cancer in the world? Gastric cancer in Japan was ranked as the most common cancer in the past, but this aspect has gradually been changing in recent years. In 1999, the leading cause of cancer death from gastric cancer was overtaken ...
BACKGROUND AND OBJECTIVE Pepsinogen levels in plasma are increased by inflammation in the gastric mucosa, including inflammation resulting from Helicobacter pylori infection. A decrease in pepsinogen II level has been suggested as a reliable marker to confirm the successful eradication of infection. The aim of our study was to evaluate the potential role of pepsinogens I and II, gastrin-17 and ...
The aim of this study was to determine the age-specific prevalence of Helicobacter pylori infection in infants and children aged 1-99 months from a poor periurban community in Bangladesh. We also examined the frequency of infection among infants and their 53 immediate family members and evaluated the relationship between infection and fasting serum group II pepsinogen (pepsinogen II) concentrat...
Weekend treatment with 20 mg omeprazole reduces ulcer relapse rates but the results may improve with a higher dose regimen. We have evaluated three day weekend treatment with 20 and 40 mg doses of omeprazole in eight healthy subjects in a double blind crossover study. Twenty four hour ambulatory intragastric pH and basal and meal stimulated serum gastrin and serum pepsinogens A and C values wer...
1. Solubility curves of crude pepsin preparations indicate the presence of more than one protein. 2. One of these proteins has been isolated and crystallized and found to have constant activity and constant solubility in several solvents. 3. The solubility measurements are complicated by the unstable nature of the protein and the fact that in certain solvents the solubility of the protein is ma...
