Figure 3. Ligustilide ameliorates neurodegeneration in SAMP8 mice. (A) Western blot analysis of (B) postsynapticdensity 93 (PSD93), (C) postsynapticdensity 95 (PSD95) and (D) BDNF. Ligustilide 10 (10 mg/kg/d); Ligustilide 20 (20 mg/kg/d). Data represent mean ± SD (n = 20 per group). #p < 0.05, ##p < 0.01, ###p < 0.001 versus SAMR1; *p < 0.05, **p < 0.01, ***p < 0.001 versus SAMP8.
