Honokiol attenuates the oxidative stress in rats with ALI via activation of Nrf2. A, B, D, E Relative expression levels of Nrf2 and HO-1 protein in lung tissues analyzed by Western blot. C, F Relative expression levels of Nrf2 and HO-1 mRNA in lung tissues were analyzed by RT-PCR. G–I The levels of MPO, MDA and SOD in bronchoalveolar lavage fluid of each group were detected by ELISA. Data were analyzed using one-way ANOVA; n = 7–8 rats per group. ^**P < 0.01 compared with the control group; ^#P < 0.05, ^##P < 0.01 compared with LPS group
