Representative photomicrographs of lung alveolar spacesin haematoxylin-eosin-stained sections of air-exposed mice (a),ozone-exposed mice (b), MitoTEMPO-treated ozone-exposed mice (c), VX765-treated ozone exposed mice(d). (bar = 100 μm). Effects of MitoTEMPO and VX765 on multiple ozone exposure-induced increase in mean linear intercept (Lm) (e) and changes in airway structure including thickness of airway epithelial layer (Wae/Pbm) (f), airway smooth muscle (Wam/Pbm) (g) and total airway wall (h). *P < 0.05, **P < 0.01, *** P < 0.001. One-way analysis of variance (ANOVA) with Bonferroni or Dunnett’s T3 post-test analysis was performed for comparisons between multiple groups
