Figure 2. SalB ameliorates oxidative stress in P. gingivalis-infected mice. The levels of ROS (A), MDA (B) and the enzymes activities of SOD (C), GSH-Px (D) were detected in the hippocampus of P. gingivalis-infected mice. Experimental values were expressed as mean ± SEM (n = 6 per group). *P < 0.05, **P < 0.01 vs. Control; #P < 0.05, ##P < 0.01 vs. P.g.
