Effects of MMMM on memory impairment in the in vivo AD model. (A) The 5XFAD mice were treated with MMMM (30 mg/kg/day) for 8 weeks and underwent the indicated experiments in accordance with desired protocols. Using Y-MT, the extents of (B) total arm entries and (C) spontaneous alteration in mice groups administered with different treatments were obtained. Using PAT, (D) step-through latencies of mice groups administered with different treatments were quantified. In all graphs, * p < 0.05 and ** p < 0.01 vs. WT; # p < 0.05 vs. Tg. Data are represented as the mean ± standard deviation. p.o, per oral; Y-MT, Y-maze test; PAT, passive avoidance test; Thio-S, Thioflavin S; IHC, immunohistochemistry. N.S; no significance.
