Summary

The aims of this study are 1) to determine the cytokines produced by both Th1 and Th2 subsets in gastric antral biopsy specimens from Taiwanese patients before and after anti H. pylori therapy; 2) to obtain a detailed phenotypic characterization and distribution pattern of mucosal lymphocytes in H. pylori-associated gastritis and to define possible contributing immune mechanisms responsible for the chronicity of the disease and its associated lesions.
