Terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) assays to measure apoptotic cell death by light microscopy. A) TUNEL-positive (brown color) cells with apoptotic morphology were observed in all groups (x200). B) A graph demonstrating the apoptosis/necrosis rates in all groups by image J software (*P < 0.05, compared to group A).
