Fig. 8. Evaluation of phospholipids in bronchoalveolar lavage fluid. Bronchoalveolar lavage fluid was collected after 6 h in the four study groups (propofol–lipopolysaccharide [LPS], propofol–phosphate-buffered saline [PBS], sevoflurane [Sevo]–LPS, and Sevo–PBS). Phospholipid assay was performed with supernatants. *  P < 0.05  versus propofol–LPS. Propofol–LPS, propofol–PBS: Instillation of LPS or PBS intratracheally, followed by ventilation and sedation with propofol for 6 h. Sevo–LPS, Sevo–PBS: Instillation of LPS or PBS intratracheally, followed by ventilation and sedation with propofol for 2 h and with sevoflurane for the following 4 h. Values are mean ± SD from n = 6 (LPS) and n = 4 (PBS) experiments.
