Figure 2. The effects of PD on ROS, w/d, MPO and oxidative stress. (A–C) ROS, w/d and MPO (n=6); (D–F) SOD, MDA and GSH-Px in serum (n=6); (G–I) SOD, MDA and GSH-Px in serum (n=6). All the data was presented as mean ± SD. Compared with control group: #P<0.05, ##P<0.01. Compared with model group: *P<0.05, **P<0.01.
