Data are presented as mean ± SEM. ∗P < 0.05, ∗∗P < 0.01 and ∗∗∗P < 0.001; compared to the control group. +P < 0.05, ++P < 0.01 and +++P < 0.001; compared to COPD. £P < 0.05, ££P < 0.01 and £££ P < 0.001; compared to COPD group-treated with 4 ml/kg CM group. #P < 0.05, ##P < 0.01 and ###P < 0.001; compared to Dexamethasone. Statistical analyses were performed using one-way analysis of variance (ANOVA) with Tukey-Kramer's post-test.
