MnSod, Cu-ZnSod and trxr1 expression levels at different reperfusion times. MnSod (A), Cu-ZnSod (B) and trxr1 (C) expression levels in short and long reperfusion times upon 30 min of ischemia. Sham animals were pooled together as there were no evident differences between short and long reperfusion times (sham n = 5; short n = 9; long n = 6). Results are expressed as mean ± SE. *p < 0.05; ** p < 0.01; ***p < 0.001.
