FCM cell cycle analysis of apoptotic index (AI) for cells treated with As 2 O 3 and/or DDP. AI for the control A549 cells and cells treated with As2O3, DDP, or the combination were 0.25 ± 0.01%, 10.6 ± 0.53%, 15.85 ± 0.79%, and 20 ± 1%, respectively; the AI for the control H460 cells and cells treated with As2O3, DDP, or the combination were 1.95 ± 0.11%, 13.6 ± 0.65%, 7.53 ± 0.43%, and 35.6 ± 1.71%, respectively.
