Effect of STAT3 decoy ODN transfection on lung injury in mice following CLP-induced sepsis. Lung tissues were harvested from sham-operated and CLP-induced septic mice 18 h after surgery. (A) Lung tissue sections stained with hematoxylin and eosin. (B) Lung tissue sections were stained with antibody against MPO followed by peroxidase staining. MPO-positive cells were stained brown and indicated by red arrowheads. Scale bar, 100 μm. (C) Semiquantitative analysis of lung tissues by lung injury, which was assessed by scoring from 0 to 4 as described in Methods (n = 6). (D) Quantitation of MPO-positive cell counts in lung tissues. The average of MPO-positive cell number in five fields per sample was calculated (n = 6). ***P < 0.001 compared with the respective control (18 h after sham operation). ###P < 0.01 compared with CLP alone.
