<p>(<b>A</b>) Total cell numbers, (<b>B</b>) macrophages and (<b>C</b>) neutrophils in the BAL fluid of mice exposed to air or whole body cigarette smoke twice daily during 5 days. The mice received vehicle (PBS) or VPA (100 µg/70 µl PBS) by oropharyngeal aspiration 15 minutes prior to air/smoke exposure. (<b>D</b>) acPGP was measure in the BAL fluid. (<b>E</b>) PE activity was measured in the BAL fluid and compared to control (PBS treated/air exposed mice). N = 5–10 animals per group. Values are expressed as mean+/−S.E.M. **P≤0.01, ***P≤0.001, ns p>0.05.</p
