Acute pulmonary effects of CeO2 nanoparticles in mice. The comparison experiment was carried out in C57BL/6 mice exposed to CeO2 nanoparticles C1, C2, C3 and C5 at 2.0 mg/Kg by oropharyngeal aspiration. There were 6 animals per group. Mice were sacrificed at 40 hr and the neutrophil cell counts (A), LIX (B) and IL -1β (C) levels in BALF were determined. QTZ at 5.0 mg/Kg was used as a positive control. The experiment was reproduced a second time; * p < 0.05 compared to control; # p < 0.05 for pairwise comparisons as shown.
