H&E staining of lung tissue in mice. (a), (b), (c), and (d) represent lung tissue sections from the NC, CS, NTHi, and NTHi + CS groups, respectively (left: 200×; right: 400×). Black arrows in (b), (c), and (d) represented the infiltrating inflammatory cells. Red arrows represented thicker alveolar septum. (e) The mean linear intercept. Lm was calculated from the number of intercepts, the length of the line, and the number of times the line was placed on the sections. n = 3-4 in each group. Data was expressed as mean ± SD. Analysis of differences among groups was conducted with one-way ANOVA-LSD. versus NC; and versus CS.
