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

Figure 4 Labeling indices for p53 (DO-7) in group A with more than 6 positive cells for p53 (PAb240) per 10 gastric pits (n = 12) and group B with less than 5 positive cells for p53 (PAb240) per 10 gastric pits (n = 30) before eradication. Results are shown as mean ± SEM. Labeling indices for p53 (DO-7) were significantly higher for group A than for group B at all biopsy sites except for the lesser curvature of the antrum. ^aP < 0.05, ^bP < 0.01, NS, not statistical.
