Effect of PEF on the viability of H9C2 cells under I/R conditions. A The H9C2 cells were treated with PEF from 10 to 400 µg/ml under normal. B The H9C2 cells were treated with PEF from 10 to 400 µg/ml under I/R conditions. C H9C2 cells were treated by PEF (200 µg/ml). D Light microscope image of H9C2 cells were treated by PEF (200 µg/ml). The experimental data are from three independent experiments (n = 3) and are presented as the mean ± SD. ^*P < 0.05 vs. Normal, ^$P < 0.05 vs. I/R, ^#P < 0.05 vs. Normal + PEF
