FIG. 2.

Panel A: H&E-stained lung sections showing representative changes in alveolar thickness seen after radiation only treatment (R), localized bronchial damage widely seen after fungal treatment only associated with the invasion of inflammatory cells (S), and alveolar thickening combined with localized damage when the dual treatments were given (R +S). Original magnification 200×. Panel B: Enlarged representative images 24 h post-treatment showing typical pulmonary architecture from untreated control animals (C), changes in alveolar thickening associated with exposure to 2 Gy whole-body X radiation (R), invasion of inflammatory cells around individual bronchioles that are typically seen after fungal inoculation only (S), and combined damage after dual treatment of radiation and fungal spores (R + S). Original magnification 20×.
