^aNormal (BALB/c) mice (n = 3/group) were exposed to adenovirus and at the subsequent times indicated were sacrificed and subjected to BAL. Cells were recovered from BAL fluid by centrifugation and evaluated in cytocentrifuge preparations by routine cytological analysis. At least 200 cells were counted for each determination.
