P90 and AS-PAH induced an inflammatory response in vivo. The diagrams show relative lung weights (a), the amount of total cells (b) and results of differential cell counts in BAL fluid (c-e) after nose-only inhalation. Data are mean ± SD; n = 10 results of relative lung weight; n = 5 for total cell count and differential cell counts; *p < 0.05 and **p < 0.01 CBNP exposure compared to clean air control, analyzed by analysis of variance and Dunnett’s test; PMNs = polymorphonuclear cells, D1 = day 1 post-exposure, D14 = day 14 post-exposure
