Figure 2. Danggui-Shaoyao-San rescued learning and memory deficits in APP/PS1 transgenic mice. (A) The genotype identification of APP/PS1 double transgenic mice; (B) Escape latency during the acquisition phase of the Morris water maze test; (C) The number of crossings over the previously hidden platform area in the Morris water maze test; (D) Escape latency during the visible platform phase of the Morris water maze test. N = 10 mice/group; Age = 7 months; Data are represented as mean ± standard deviation (SD), *, P< 0.05. (E) Immunohistochemistry of amyloid-β in the brain. N = 5 mice/group; Data are represented as mean ± SD, *, P< 0.05. (F) The protein expression of synaptic markers. N = 4 mice/group; Data are represented as mean ± SD, *, P< 0.05.
