Fig. 5.

Western-blot analysis of Akt, P-Akt, p38, P-p38, STAT3, and P-STAT3 proteins expression in lung tissues of limb I/R-induced ALI rats. Top representative bands from Western blots of a P-Akt and total Akt, b P-p38 and total p38, c P-STAT-3 and total STAT-3. Bottom bar graphs show mean ± SD of the densitometry of a P-Akt-to-Akt ratio, b P-p38-to-p38 ratio, and c P-STAT-3-to-STAT-3 ratio. All data are expressed as mean ± SD (n = 8 animals/group). Significant differences are indicated as: ^a p < 0.01 vs. control group, ^b p < 0.01 vs. I/R group, ^c p < 0.05 vs. I/R + SO₂ group
