Fig. 3. Myocardial terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labeling (TUNEL) staining (n = 8 for each group). Representative high-power field with TUNEL-stained apoptotic nuclei in green and nonapoptotic nuclei in blue. Apoptosis quantification was performed by counting TUNEL-positive cells (magnification, ×400). Data are given as mean ± SD percentage of apoptotic cells (10 fields per heart were analyzed). *P = 0.05 and *P = 0.039. Isch-postC = ischemic postconditioning; sevo-postC = sevoflurane postconditioning.
