The proportion of phospho-NF-κB subunit p65 positive cells in lung tissues of different groups. The cells were counted under laser scanning confocal microscopy (magnification, ×400). The data are expressed as mean ± standard deviation (SD) (n = 8). ^▲ P < 0.01; ^△ P < 0.05 vs. group S; ^□ P < 0.05 vs. group M; ^◇ P < 0.05 vs. group D2.
