Figure 1.

BAL total protein concentration. The total protein concentration of cell-free BAL fluid was determined. The total amount of fluid recovered during BAL (~90% of instilled volume) did not differ significantly among groups. The histogram depicts mean protein concentration values (n = 4/group) and standard deviations are indicated by error bars. Values of WT mice that differ significantly (p < 0.05) from baseline by t-tests are indicated by an asterisk (*) and values of SP-A-/- mice that differ from baseline values are indicated with a pound sign (#).
