Figure 4).

Graph showing the effect of metoprolol on apoptosis following coronary microembolization (CME). Cells that stained positive in the terminal deoxynucleotidyl transferase dUTP nick end labelling assay after CME were detected primarily in myocardial microinfarction foci and the peripheral zones. In control animals, myocardial apoptosis was occasionally found in the subendocardium and papillary muscles. Data (n=10 per group) are expressed as mean ± SD. *P<0.05 compared with the control group; ^#P<0.05 compared with the CME group. ZLF Z-LEHD-FMK
