Western blot (A) against the 75 kDa subunit (NDUFS1) of NADH dehydrogenase (complex I) in control (CON), APC, ischemia and reperfusion (ISCH), and APC followed by ischemia and reperfusion (APC+ISCH) groups. B: the data (means ± SD) summary resulting from densitometry of 3 different blots. C: attenuated enzymatic activity of NADH dehydrogenase (complex I) in the ISCH group that was restored by APC. NADH dehydrogenase activity was measured in solubilized cardiac mitochondria isolated from the four experimental groups. Data are means ± SD, n = 4/group. *Significantly (P < 0.05) different from CON; #significantly different from APC.
