Effects of mechanical ventilation after PA or normal saline instillation on lung MPO activity, total number of cells, and total protein concentration in BALF of WT and JNK1^−/− mice. a Mechanical ventilation after saline or 1 × 10⁶ CFU PA instillation induced lung MPO activity in WT mice but not in JNK1^−/− mice. n = 5-6/group. b Mechanical ventilation after PA instillation increased the total number of cells in BALF in WT mice but not in JNK1^-/- mice. c Mechanical ventilation after PA instillation increased the total protein concentration in BALF of WT mice but not in JNK1^−/− mice. n = 5-6/group. PA, Pseudomonas aeruginosa. *P < 0.05, **P < 0.01, ***P < 0.001
