a Apoptosis analysis of the lung tissues in limb I/R-induced ALI rats with different treatments. DAPI staining and TUNEL assay. The lung tissue nuclei appeared light blue, TUNEL-positive nuclei appeared green (n = 8, 5 fields for each specimen). b The quantitative analysis of the apoptotic index in different experiment groups. Results are given as mean ± SD (n = 8 animals/group). Significant differences are indicated as: *p < 0.01 vs. control group, # p < 0.01 vs. I/R group, ∆ p < 0.05 vs. I/R + AIR group
