Inflammatory cell numbers recovered by BAL at 72 h following LPS inhalation. Lungs were lavaged three times using the same 5 ml of saline and BAL cells were analyzed by staining cytospins with Wright-Giemsa. (A) The total numbers of inflammatory cells increased in a dose-dependent manner. (B) The number of macrophages and neutrophils (C) and lymphocytes were quantified. Values are group means ± SE; (n = 6 rats per group). * = Significantly different from air-exposed- controls, P < 0.05.
