Effects of obacunone against lipopolysaccharide (LPS)-triggered oxidative stress in induced acute lung injury (ALI). A Representative dihydroethidium (DHE) fluorescence images of BEAS-2B cells. B Representative DHE fluorescence images of the mouse lung tissues. C–F Activities of malondialdehyde (MDA), catalase (CAT), glutathione (GSH), and superoxide dismutase (SOD) in the mouse lung tissues. Similar results were obtained from three independent experiments. All data are presented as mean ± SEM (n = 6 for each group). ^#/*P < 0.05, ^##/**P < 0.01, ^###/***P < 0.001, ^# versus control group; * versus LPS group; ns, no significant difference between control and OB group
