Representative H&E photomicrographs of the lung parenchyma from the Control a ARDS b and H1N1 c groups. Observe the presence of hyaline membranes (hm) in the ARDS group and inflamed and oedematous alveolar septa with hyaline membranes (hm) in the H1N1 group. Representative photomicrographs of the small airways from the Control d, ARDS e and H1N1 f groups, stained with H&E. There is small airway (br) oedema with epithelial denudation and the presence of inflammatory cells in the bronchioles (br) in the ARDS and H1N1 groups
