Lung blast injury induces lung tissue oxidative stress. (a) Western blot was used to detect the expressions of SOD-1, MDA5, and IREα proteins. (b–d) Real-time PCR was used to detect the expressions of SOD-1, MDA5, and IREα mRNA. (e) Dihydrodepine to detect lung tissue ROS. *P < 0.05, compared with the control group, n = 5.
