CXCL8 and acute respiratory distress syndrome: In lung tissue (Figure 3a,b,d,f), decreased levels of cytokines and TBARS were observed after both therapies compared to that in the ARDS group simultaneously, for DEX: IL-1β (p = 0.000; CI: 234.10, 311.30), TNFα (p = 0.000; CI: 29.79, 117.30), IL-8 (p = 0.000; CI: 157.70, 432.80), and TBARS (p = 0.001; CI: 5.10, 18.95); and for NCX-1005: IL-1β (p = 0.000; CI: 257.60, 334.90), TNFα (p = 0.000; CI: 41.32, 132.20), IL-8 (p = 0.000; CI: 129.50, 404.60), TBARS (p = 0.005; CI: 2.66, 16.51), and 3NT was borderline (p = 0.058; CI: −0.38, 20.40).
