Cardioprotective Effects of Astragalin against Myocardial Ischemia/Reperfusion Injury in Isolated Rat Heart

Figure 4

Effects of astragalin suppression on cardiomyocyte apoptosis (×400). (a–e) Representative immunohistochemical staining for apoptotic cell (which were manifested as a marked appearance of dark brown cell nuclei, as the red arrows noted) in rat myocardium in the different groups (bar = 50 μm). (f) Quantitative measurement of the TUNEL index (apoptosis %) in different groups (data are presented as mean ± SD, ). compared with the control group; and compared with the I/R group.
