Edaravone Attenuated Particulate Matter-Induced Lung Inflammation by Inhibiting ROS-NF-κB Signaling Pathway
Figure 3
EDA alleviated the PM-induced inflammatory responses in vivo. Mice were intratracheally instilled with PM at 100 μg/day/mouse for 2 consecutive days. EDA (2, 10, or 20 mg/kg) was intraperitoneally injected prior to PM exposure for 1 h. (a) Representative images of lung sections stained with H&E. (b) The inflammation score for images of lung sections stained with H&E. (c) The number of the total cells, neutrophils, and macrophages in BALF. Values are the ; , compared with the control group; # or ##, compared with the PM group; . EDA: edaravone; PM: particulate matter; BALF: bronchoalveolar lavage fluid.
