Secretion of IL-12. Relationship between secretion of IL-12 and grade of chronic inflammation (mononuclear cell infiltrate, Sydney system) in Helicobacter pylori-positive and H. pylori-negative gastritis. Secretion of IL-12 in antrum biopsy cultures increased with the severity of chronic gastritis only in H. pylori-positive gastritis. An increased IL-12 secretion was seen in H. pylori infection in comparison with H. pylori-negative patients. Square brackets indicate significance of statistical differences.
