 AB    We isolated lymphocytes from chronically inflamed gastric mucosa. We
       analysed the expression of IL-2 receptors (CD25), transferin receptors
       (CD71) and HLA-DR molecules on T lymphocytes by flow cytometric analysis
       in 16 patients with urease-positive and in 7 patients with
       urease-negative chronic gastritis. In G0, G1 and G2 histological type
       (Sydney classification) of gastritis the number of lymphocytes obtained
       from the gastric mucosa biopsies was too low for the flow cytometric
       analysis. However, in G3 histological type of chronic gastritis we
       obtained enough cells for the flow cytometric analysis in 75%. We
       demonstrated a significant increase in HLA-DR expression on CD8 cells
       from patients with urease-positive gastritis compared to urease-negative
       gastritis. We also observed a statistically non-significant increase in
       HLA-DR expression on CD3 cells, and in CD71 expression on both CD3 and
       CD8 cells in urease-positive gastritis. However, no difference in CD25
       expression was found between the two types of gastritis.
