Fig. 5. TUNEL staining of myocardial apoptosis in the four groups. (A–D) Sham, sham + Pue, CME, CME + Pue group, respectively. Data are expressed as mean ± standard deviation. Nuclei of apoptotic cardiomyocytes were yellow-brown, whereas the normal cardiomyocytes that did not show apoptosis were light blue. The arrows in (C and D) indicate the nuclei of apoptotic cardiomyocytes. CME, coronary microembolization; Pue, puerarin. ap < 0.05 in comparison with the sham group; bp < 0.05 in comparison with the CME group.
