Effects of As₂O₃, GSPE, and BAY 11–7082 on LPO and ROS of BEAS-2B cells. The BEAS-2B cells were treated with As₂O₃ (0, 5, 10, or 20 μmol/L) (n = 3) and/or GSPE (0, 25, or 50 mg/L) (n = 3), all in combination with BAY 11–7082 (50 μmol/L). Values are expressed as means ± SD. ^aP < 0.05, compared with blank control group; ^bP < 0.05, compared with arsenic group (5 μmol/L); ^cP < 0.05, compared with arsenic group (10 μmol/L); ^dP < 0.05, compared with arsenic group (20 μmol/L).

GSPE: grape seed proanthocyanidin extract; LPO: lipid peroxide.
