From: Double impact of cigarette smoke and mechanical ventilation on the alveolar epithelial type II cell
Neutrophils in bronchoalveolar lavage fluid with and without exposure to smoke and mechanical ventilation. The four groups depicted are nonsmoke/nonventilation (NS-NV), smoke/nonventilation (S-NV), nonsmoke/ventilation (NS-V) and smoke/ventilation (S-V). To the right of the dot blots, mean ± SD values are indicated by bars. The combination of the two stimuli resulted in a significant increase in polymorphonuclear cells (P < 0.01) compared to all other groups, including NS-V rats.
