PD98059 reduced the effects of hyperoxia on stretch-induced neutrophil infiltration, macrophage inflammatory protein-2 (MIP-2) production, and microvascular leak. The mice ventilated at a tidal volume (VT) of 30 ml/kg (VT 30 ml) with and without hyperoxia were pretreated with 1 mg/kg PD98059 for 30 minutes. (a) Myeloperoxidase (MPO) assay of lung tissue (n = 5 per group). (b) MIP-2 production in bronchoalveolar lavage (BAL) fluid (n = 5 per group). (c) Evans blue dye (EBD) analysis of lung tissue (n = 5 per group). *p < 0.05 versus control, non-ventilated mice; †p < 0.05 versus all other groups. ERK, extracellular signal-regulated kinase; OD, optical density; RA, room air.
