a The percentage of nuclear factor-kappaB immunoreactive cells (%) and b apoptotic cells (%) in all experimental groups (six rats each). Figure 2c were representative images of immunohistochemistry for NF-kappaB (× 40 magnification). Positive cells were gastric epithelial cells with brown-stained nuclei. Figure 2d were representative images of TUNEL stain (× 100 magnification). Arrows indicated gastric epithelial cells with brown-stained nuclei. Data are expressed as mean ± SD. (^aP < 0.05 vs. Con group; ^bP < 0.05 vs. HP group. Con: Control group; HP: H. pylori infection group; HP + Gen: H. pylori infection and genistein treatment group)
