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

Table 3 The differences of updated Sydney system score between the group showed more than six positive cells for p53 (PAb240) per 10 gastric pits (group A) and the group showed less than five cells for p53 (PAb240) per 10 gastric pits (Group B)
