Effect of IL-33 neutralization on lung impairments and production of MMP2/9 in LPS-induced ALI rats. (a-d) Lung wet/dry ratio (a), protein contents in BALF (b), total cells in BALF (c) and macrophages in BALF (d) in LPS-induced ALI rats treated with or without IL-33 antibodies. (e and f) Concentrations of MMP2 (e) and MMP9 (f) in BALF of LPS-induced ALI rats treated with or without IL-33 antibodies. Data are shown as means±SD (N = 9 per group). Two-way ANOVA was used in the statistical analyses. * p < 0.05, ** p < 0.01, *** p < 0.001
