Bronchoalveolar lavage fluid (BAL) cell differentials and protein concentration. Dose dependent influx and time dependent resolution of (a) polymorphonuclear leukocytes (PMN), (b) macrophages, and (c) lymphocytes in the BAL following intratracheal (i.t.) instillation of carbon nanoparticles particles in the JF1/Msf (JF1) mice (n = 7 animals/experimental group). Total protein concentration is provided in Figure 1d. (**) Significantly different with respect to (w.r.t) both sham control and 5 μg exposed; (***) significantly different w.r.t 20 μg exposed at day1, sham control and 5 μg exposed; p ≤ 0.05.
