Figure 6

Number of differential cells in BAL fluid in controls and animals exposed to ZnO NPs for period of 2 (A) or 13 wks (B). In both studies there was a significant increase in number of macrophages in BAL fluid, in comparison with shams necropsied at the same time after exposure. The number of neutrophils was significantly increased only in sub-acute study, however biologically this increase was just marginal. Data are expressed as mean ± SE.
