Effect of NBD on SOD and T-AOC activity and MDA concentrations in the lung tissues of mice with ALI. LPS challenge significantly increased MDA levels and decreased SOD and T-AOC activity compared with sham controls; however, treatment with the middle and large NBD concentrations exerted effects contrasting with those described above. Data are expressed as the mean ± SD (n = 6). A represents versus control group, ^A P < 0.05; B represents versus model group, ^B P < 0.05; C  represents versus N-NBD group, ^C P < 0.05; D represents versus NBD-2 group, ^D P < 0.05.
