The antioxidative enzyme activity of different drug groups on 300 μM PQ treated A549 cells. The mRNA expression of CAT (a, d), HO-1 (b, e) and SOD (c, f) at 6 and 12 h, respectively; (*) denotes statistical significance compared with the control group (*p < 0.05; **p < 0.01); (#) denotes statistical significance compared with the model group (#p < 0.05; ##p < 0.01)
