FIG. 7.

Lung inflammation as determined by analysis of cells in BALF after air or ozone exposure in SHAM, DEMED, or ADREX rats. BALF cell differentials were performed to quantify macrophages, neutrophils, and eosinophils at both time points after air or ozone exposure (1-D, 2-D). A, Neutrophils and B, Eosinophils. Data for macrophages are not shown. Circulating white blood cells (WBC) and platelets were also quantified. C, WBC and D, Platelets. Values indicate mean ± SEM (n = 4–6/group). *Indicates ozone effect when compared with matching air group at a given time point. †Indicates surgery effect within matching exposure group at a given time point P ≤ .05.
