The expression of IL-1β, IL-6, IL-10, and TNF-α in the plasma and lung from limb I/R-induced ALI rats in different experiment groups. a IL-1β protein. b IL-6 protein. c IL-10 protein. d TNF-α protein. Results 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
