  1. Fluid recovery and cell counts (absolute and percentage of cells) in bronchoalveolar lavage of healthy, non smoking subjects (H) young smokers (S1), elderly smokers (S2) and smokers with COPD (C). Values are given as means ± SEM; * indicate p < 0.05 and # p < 0.01 compared to healthy non-smokers (H).
