Figure 4.SalB improves neurotrophic factors in P. gingivalis-infected mice. The mRNA levels of bdnf (A) and ngf (B) 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
