Age-related effects of O3 on lung permeability and airway neutrophilia. Levels of albumin (a), neutrophil counts (b), and total cell numbers (c) were determined in the BAL fluids after exposure to O3 or FA. Values are mean ± SEM (n = 3–6 mice/group). *: p < 0.05, compared with age-matched FA-exposed controls; #: p < 0.05, compared with 1-week old group; $: p < 0.05, compared to all other age groups
