Inflammatory cells measured in BALF. Rats were exposed to clean air, 0.1, 0.3, 1.0, and 3.0 mg/m3 CeO2 nanoparticles or 50.0 mg/m3 BaSO4 nanoparticles. a, b relative and absolute polymorphonuclear neutrophils (PMN) levels and c, d relative and absolute lymphocytes (LYMPH) levels, determined at exposure day one and 28 as well as post-exposure day one, 28 and 90. Values are expressed as percentage of total cell number or absolute value, mean ± SD, * p < 0.05, ** p < 0.01, *** p < 0.001 vs. clean air control, n = 5; Kruskal-Wallis-ANOVA with Mann-Whitney U-Test as post-hoc analysis
