Figure 3. Bronchoalveolar lavage fluid (BALF) inflammatory parameters in B10, 4R, 5R, 2R, and A/Wy mice exposed continuously to 0.3 ppm O3 or air for 48 or 72 h.
A. Macrophages; B. Polymorphonuclear leukocytes (PMNs); C. Epithelial cells; D. Total BALF protein. Data are presented as means ± SEM (n=3-12 per experimental group). *, Significantly different from air exposed mice (P < 0.05). +, Significantly different from B10 mice (P < 0.05).
