Macrophage inflammatory protein-2 (MIP-2) concentrations in bronchoalveolar lavage fluid (BALF) from lungs of mice after different ventilatory protocols. A: groups received either no ventilation, ventilation for 1 h without treatment at 10 cmH₂O PIP (PIP10), or ventilation for 1 h with 40 cmH₂O PIP (PIP40) with and without pretreatment with OGG1. B: groups received either no ventilation or ventilation for 2 h with 40 cmH₂O PIP (PIP40) with and without pretreatment with OGG1. C: groups received either no ventilation or ventilation for 2 h with 50 cmH₂O PIP (PIP50) with and without pretreatment with OGG1. *P < 0.05 vs. No Vent. group. #P < 0.05 vs. all other groups. †All animals in the untreated PIP50 group died before 2 h.
