Pulmonary responses to oxygen exposure. Wild-type mice were exposed to 80% oxygen for the indicated time points (A and C–F) or for 4 days (B). Neutrophil counts in BALF (A), neutrophil counts in lung cell suspensions at 4 days (B), KC (C), IL-6 (D), total protein (E), and alkaline phosphatase (AF) (F) in BALF. Data are mean ± SE of 6 to 8 mice per time point. Depicted P values are obtained from Kruskal-Wallis tests for analysis of overall differences within groups in time (A and C–F). *P < 0.05 versus t = 0; **P < 0.01 versus t = 0; ***P < 0.001 versus t = 0 (A and C–F) as analyzed by Dunn’s post tests as described in the Materials and Methods section. *P < 0.001 versus wild-type mice (B) as analyzed by Mann-Whitney test.
