Effect of wogonin on the apoptosis of LPS-induced A549 cells. Cell apoptosis was assessed by acridine orange/ethidium bromide (AO/EB) double fluorescence assays. Results were generated from three independent experiments (n = 3). ***P < 0.001 vs. control; ^###P < 0.001 vs. LPS; ^&&&P < 0.001 vs. LPS + 5 μM wogonin; ^@@P < 0.01 vs. LPS + 10 μM wogonin
