  1. A. Number of cells in BALf after a week of bleomycin treatment. B. N umber of CD45+ cells in BALf before and on days 7, 14 and 21 after bleomycin treatment (one intratracheal dose of 0.074 U/ml in 40 ml volume). C. Number of (CD45+) cells in lung parenchyma (LP) before and after bleomycin treatment. D. Number of CD45- cells in LP counterstained with alveolar epithelial cell markers before and after bleomycin treatment. After the single intra-tracheal dose of bleomycin, animals were sacrificed on days 7, 14 and 21 for the WT after bleomycin, and at days 7 and 21 only for the NOX-/- and DKO mice and WS. Cell number was quantitated by hemocytometer and corroborated by Z1 particle counter (Beckman Coulter). Number of cells represent data from 2 independent experiments ± SEM. n = 4/group. Cell subsets were quantified by FACS and morphologic differentiation under light microscope. Olympus BX41 at 40 × magnification. CD45+ cells were gated and macrophages (Gr1-F4/80hi), lymphocytes (CD3+ and B220+), and neutrophils (Gr-1hi F4/80-) were identified, their percentages analyzed by CellQuestPro and their total numbers calculated from the total number of cells obtained by lavage as described in materials and methods. Data presented were pooled from 2 independent experiments ± SEM. *P < 0.05 compared to WT post-bleomycin on corresponding time points).
