Gas exchange (Supplemental Table S1), lung mechanics (Figure 1), levels of IL-6, TNF-α, and TGF-β in lung tissue homogenate (Figure 4), MPO activity (Figure 5), and PCIII mRNA expression (Figure 6) did not differ significantly between the two groups, whereas protein level of IL-10 was higher (Figure 5) and PCI mRNA expression was lower (Figure 6) in Obese-ALI than Control-ALI. This evidence concerns the gene IL6 and acute respiratory distress syndrome.
