The results showed that significantly increased IL-17 level was found in lung tissue lyse (Control: 6 h: 12 h: 24 h = (32.96 ± 12.26) : (121.3 ± 18.71) :(135.5 ± 27.1) : (124.5 ± 9.68) pg/mg protein; all the p < 0.05 vs. control) (Figure 2A), mBALF (Control: 6 h: 12 h: 24 h = (5.9 ± 1.32): (25.4 ± 4.67): (29.8 ± 4.07): (20.2 ± 4.31) pg/mL; all the p < 0.05 vs. control) (Figure 2B) and plasma (Control: 6h: 12h: 24 h = (10.6 ± 3.61) : (59.3 ± 8.19): (65.1 ± 8.43): (53.0 ± 6.75) pg/mL; all the p < 0.05 vs. control) (Figure 2C) at 6, 12 and 24 h after ALI when compared to the non-ALI controls. This evidence concerns the gene IL17A and acute respiratory distress syndrome.
