Aggravating Effects of Psychological Stress on Ligature-Induced Periodontitis via the Involvement of Local Oxidative Damage and NF-κB Activation
Figure 8
Detection of oxidative stress indices: (a) ROS content; (b) malondialdehyde content; (c) superoxide dismutase activity; (d) catalase activity; (e) glutathione peroxidase activity. C: control rats; EP: rats with experimental periodontitis; PS: rats exposed to psychological stress; EP+PS: rats with experimental periodontitis exposed to psychological stress; EP+PS+DR: rats with experimental periodontitis exposed to psychological stress and treated with fluoxetine. The data are expressed as , vs. the C group; #, vs. the EP+PS group.
