In vivo experiment. (A) Lung tissue analysis using hematoxylin and eosin staining. Representative images of (a) Control group; (b) LPS group; (c) LPS + YDJDG group; (d) LPS + MP group. (B) Wet/dry weight ratio and (C) Histological score, (D) The levels of cytokines in bronchoalveolar lavage fluid, (E) Expression of NF-κB p65, phosphorylated NF-κB, IκBα, and phosphorylated IκBα in the lung tissue of mice in different groups, as determined by western blot 24 h after the induction of injury. The letters a-d represents different groups: (a) Control group; (b) LPS group; (c) LPS + YDJDG group; (d) LPS + MP group. The numbers 1–6 represents the reference number of each mouse in one group. Original magnification × 200. Data are presented as mean ± standard error of mean. ANOVA followed by the post hoc Fisher's PLSD test were used. * p < 0.05; ** p < 0.001. LPS, lipopolysaccharide; YDJDG, Yindan Jiedu granules.
