From: Murine pulmonary responses after sub-chronic exposure to aluminum oxide-based nanowhiskers
Number of differential cells in BAL fluid in sentinels, mice exposed to laboratory air (shams) or mice exposed to AO nanowhiksers for 4 hrs/day for 2 or 4 wks (at daily concentration of 3.3 mg/m2 ); Data are expressed as mean ± SE; *p < 0.05, **p < 0.01, ***p < 0.001 significantly different from shams.
