Inflammations in lung. (a) Paraffin lung sections from groups (Ctl, COPD, CDSCOPD, and MZPCOPD) were stained with hematoxylin-eosin and photographed under a microscope (Leica, Wetzlar, Germany). The representative photos were from one of six to ten rats in each group. (b) The neutrophil elastase levels in BAL fluid. Data was expressed as mean ± SD (n=3). <0.01 for CDSCOPD versus the other three groups.
