Plasma and lung tissue cytokine and chemokine concentrations.

§ depicts p < 0.05 vs. the corresponding Non-CS group,
$ depicts p < 0.05 vs. the corresponding air group (K-W ANOVA Kruskall-Wallis analysis of variance on ranks with post-hoc Dunn’s test for multiple comparisons).
Plasma (in pg·mL-1) and lung tissue (in pg·mgprotein-1) cytokine and chemokine concentrations at the end of the four-hours observation period (n = 8 in each group) obtained from mice without (Non-CS) and with (CS) cigarette smoke exposure over 3–4 weeks prior to blunt chest trauma and mechanical ventilation with air (FiO2 0.21) or 100% O2 (FiO2 1.0). All data are median (quartiles).
