Figure 6

Representative immunohistochemistry staining of apoptotic proteins associated with the mitochondrial pathway at 12 h. DAB. (1000x). Positive caspase-3 or caspase-9 proteins in neutrophils (long arrows). Positive caspase-3 or caspase-9 proteins in alveolar epithelia (arrowheads). Positive Bax proteins in the neutrophil-infiltrated areas (boxes). Positive Bcl-2 proteins in the epithelial cells of respiratory bronchioles (broad arrows).
