Representative photomicrographs of liver sections illustrating expression of BCL2 antigen by immunohistochemical staining (avidin–biotin–peroxidase stain with H counter stain, magnification ×400). (A) A liver section of an adult male albino rat of normal group, showing strong positive cytoplasmic immunoreactions for BCL2 (arrows). (B) A liver section taken from an adult male albino rat of control group receiving vehicle (corn oil), showing strong positive cytoplasmic immunoreactions for BCL2 (arrows). (C) A liver section obtained from a BPA‐intoxicated adult male albino rat, showing a weak positive cytoplasmic immunoreaction for BCL2 (arrow). (D) Number of BCL2‐positive hepatocytes/μm2 surface area of liver tissue in the studied groups of adult male albino rats. Values were expressed as mean ± SD (n = 6/group). #Significantly different from normal group at P < 0.05, $significantly different from control group at P < 0.001 using anova followed by Tukey–Kramer as a post hoc test. BPA, bisphenol A; BCL2, B‐cell lymphoma 2.
