Histological scores for the lung of mice in different groups.

Group VC DEP LPS DEP + LPS
Black pigmented macrophages 0 3.2 ± 0.45 ## 0 3.4 ± 0.55 **
Granulomatous inflammation/pulmonary fibrosis 0 0.4 ± 0.55 0.4 ± 0.55 1.8 ± 0.45 **
Acute inflammation, alveolar/interstitial 0 0 2.6 ± 1.52 ## 3.8 ± 0.45
Infiltrate, neutrophilic cells, alveolar 0 0 3.2 ± 0.84 ## 3.6 ± 0.55

1: minimal; 2: slight; 3: moderate; 4: severe. Data are presented as means ± SD for five mice per group. DEP, diesel exhaust particulate. ## p < 0.001 vs. VC; ** p < 0.001 vs. LPS.
