Apoptosis of each group. A representative photomicrograph of a TUNEL (B) and DAPI-stained (A) cardiomyocytes were showed.

<p>After 2-apoptotic effect of luteolin and SP600125 by TUNEL staining. The results are expressed as the mean ± SEM, n = 3. ^#<i>P</i><0.05 versus I/R; ^$<i>P</i><0.01 versus I/R+Lut (40 µM), ^&<i>P</i><0.05 versus I/R+Lut(40 µmol/L)+PD (20 µmol/L). Cells were examined by light microscopy (200× magnification). Yellow allow indicate DAPI-stained nucleus, red allows indicate TUNEL-positive caryons.
