ROS changes in L-02 cells after arsenic and/or grape seed procyanidin extract treatment for 24 h. The more the number of FITC-A+ cells, the more the ROS in the cells: (a1) the control group, (a2) the 10 mg/L GSPE group, (b1) the 25 mg/L GSPE group, (b2) the 50 mg/L GSPE group, (c1) the arsenic (25 μM) group, (c2) the arsenic (25 μM) + 10 mg/L GSPE group, (d1) the arsenic (25 μM) + 25 mg/L GSPE group, and (d2) the arsenic (25 μM) + 50 mg/L GSPE group.
