Figure 2  .

Immunohistochemical expression of proliferating cell nuclear antigen (PCNA) in gastric crypt sections (as indicated on the figure; a mean of five well oriented crypts for each patient) of patients with functional dyspepsia, H pylori negative chronic gastritis, or H pylori positive chronic gastritis, with or without complete intestinal metaplasia (IM), before and after H pylori eradication. LI, labelling index, expressed as percentage of PCNA positive nuclei; C, controls with functional dyspepsia; nCG, H pylori negative chronic gastritis; pCG IM−, H pylori positive chronic gastritis without intestinal metaplasia; pCG IM+, H pylori positive chronic gastritis with complete intestinal metaplasia; IM−, chronic gastritis without intestinal metaplasia after H pylori eradication; IM+, chronic gastritis with intestinal metaplasia after H pylori eradication. †Three patients dropped out; intestinal metaplasia disappeared in four subjects.
