a, b MPO levels in the BALF and serum were determined (n = 6 BALF or serum samples from six mice). c, d IL-1β levels in the BALF and serum were measured (n = 6 BALF or serum samples from six mice). e, f IL-6 levels in the BALF and serum were determined (n = 6 BALF or serum samples from six mice). g, h NO levels in the BALF and serum were measured (n = 6 BALF or serum samples from six mice). i Western blots and the p-p65 and p65 expression ratio (n = 3 lung protein samples from three mice). Data represent the means ± SDs. ##P < 0.01, ###P < 0.001 compared with the sham group; *P < 0.05, **P < 0.01, ***P < 0.001 compared with the model group.
