Fig. 2. Effect of co-administering 6-SHO and L-dopa on depression-like behaviors, olfactory and memory dysfunctions in MPTP/p-injected mice. SST (A) and TST (B) were performed to evaluate depression-like behavior. Buried food test was performed to evaluate olfactory function (C). Y-maze was performed to evaluate memory function (D). Values are given as the mean ± SEM (N=5-8). Data were analyzed by one-way ANOVA followed by Dunnett’s multiple comparison test or Student’s t-test. *p<0.05 and **p<0.01 vs. MPTP/p group (One-way ANOVA); $p<0.05 vs. MPTP/p group (Student’s t-test).
