Effect of SFE treatment on the GST activity in H9c2 cardiomyocytes. After 24 h exposure to 1 μM Dox, cells were incubated with SFE for a further 24 h, and GST activities were then assessed using CDNB. ^# p < 0.05, ^### p < 0.001 compared with untreated control and ***p < 0.001 compared with Dox-treated control
