Murine pulmonary responses after sub-chronic exposure to aluminum oxide-based nanowhiskers

Table 3 Total number of cells, concentration of total protein and activity of LDH in BAL fluid in shams and AO nanowhisker-exposed mice

Parameter	Shams	Exposure to AO nanowhiskers for:
Parameter	Shams	2 wks	4 wks
Total cells/mouse, n x 10³	74.0 ± 7.9	171.6 ± 19.7 **	440.3 ± 33.6 ***
Total protein, μg/mL	107.7 ± 4.7	108.0 ± 1.5	101.2 ± 2.7
LDH activity, U/L	180 ± 18	146 ± 17	191 ± 10

Values are expressed as mean and standard error; *p < 0.05, **p < 0.01, ***p < 0.001 significantly different from sham-exposed animals.
