Histological evaluation of lungs. Lungs harvested from mice exposed to RA (A and B), CS (C and D), HK-NTHi (E to H) or CS/HK-NTHi (I to L) were inflation fixed in formalin, and embedded in paraffin. Five micron thick sections were stained with H&E and observed under light microscope. Arrows in D and L represent infiltrated inflammatory cells in alveolar space. G and K represent magnified view of marked area in F and J respectively and show accumulated macrophages in peribronchiolar area. Asterisks in D and I represents emphysema. Images are representative of 3–4 mice per group.
