CAMPYLOBACTER-PYLORIDIS INFECTION OF GASTRIC MUCOSA IN THE HIGH AND LOW RISK AREAS OF STOMACH CANCER IN CHINA

摘要

Gastric biopsies in 690 subjects from the high and low risk areas of gastric cancer were examined for identification of Cp in the gastric mucosa by Warthin-Starry, Gimenez and Gram’ s stains. The result showed that the positive rate was 60-62% in the high risk area whereas it was only 12. 6% in the low risk area in Liaoning province. 80-92% of the positive subjects had active chronic gastritis including chronic superficial and atrophic gastritis. The result Indicates a close correlation between the active chronic gastritis and Cp infection. Therefore, control of the Cp Infection in the gastric mucosa is very important for lowering the incidence of chronic gastritis, a well known precursor of gastric cancer.
