(a) Total cells retrieved by BAL were increased 7 and 14 days after injection of AdhIL-1β. The vast majority of cells at day 7 were neutrophils (b), whereas alveolar macrophages accounted for the persistent increase of total cells at day 14. Cell counts and differentials were normal by day 21. Seven days after injection, animals treated with control virus AdDL70 had a slight, insignificant increase in total cell number. Neutrophils were not elevated. ^AP < 0.01 versus AdDL70 control.
