Expression of mutant type-p53 products in H pylori-associated chronic gastritis

Figure 2 Labeling indices for p53 (DO-7) in 42 patients with H pylori infection, 6 mo after eradication, and 11 patients without H pylori infection. Results were shown as mean ± SEM. p53 (DO-7) indices were significantly reduced 6 mo after eradication at all biopsy sites. p53 indices for the H pylori-infected mucosa were significantly higher than those for the gastric mucosa without H pylori infection at all biopsy sites. ^bP < 0.001, vs H pylori non infected group.
