The total cell (A), macrophage (B), eosinophil (C), lymphocyte (D), and neutrophil (E) counts and lavage fluid protein levels (F) in the bronchoalveolar fluid and IL-8 (G), IL-13 (H), and IL-17 (I). Guinea pigs were sensitized and challenged with Ova, sensitized with Ova, and challenged with Ova + LPS or nonsensitized guinea pigs challenged with LPS. Guinea pigs were treated with twice-daily inhaled (C) vehicle or (D) dexamethasone (20 mg/ml). Naïve (unsensitized and challenged) guinea pigs are also shown for comparative purposes only. Results are expressed as mean ± S.E.M.; n = 6 or 7, *Significantly different from vehicle treatment, P < 0.05; **P < 0.01; ***P < 0.001; ^P < 0.05; ^^significantly different from naïve, P < 0.01, ^^^P < 0.001; performed with a two-tailed t test or Mann-Whitney U test where appropriate.
