Representative photomicrographs from the Control, ARDS and H1N1 groups showing Neutrophil Elastase + cells in lung parenchyma (a, b, c), and small airway (e, f, g); and CD68+ macrophages in lung parenchyma (i, j, k), and small airways (m, n, o). There was increased expression of Neutrophil Elastase+ cells and CD68+ macrophages in the H1N1 and ARDS groups compared to the Control group, in the parenchyma and small airways. The arrows indicate positive stainings. Graphs show the density of Elastase+ cells (d, h) and CD68+ macrophages (l, p) in the Control, ARDS and H1N1 groups (one-way ANOVA and Kruskal Wallis test)
