Effect of wogonin on the viability of LPS-induced A549 cells. A The chemical structure of wogonin. B The viability of A549 cells exposed to wogonin was determined by a CCK-8 assay. C The viability of LPS-induced A549 cells exposed to wogonin was estimated by a CCK-8 assay. D The LDH activity in LPS-induced A549 cells exposed to wogonin was determined by a LDH assay kit. Data were obtained from three independent experiments (n = 3). ***P < 0.001 vs. control; ^#P < 0.05, ^###P < 0.001 vs. LPS; ^&P < 0.05 vs. LPS + 5 μM wogonin; ^@@@P < 0.001 vs. LPS + 10 μM wogonin
