Changes in neuronal loss in hippocampal CA3 and DG of APP/PS1 transgenic mice treated with and without SZRD. a Microscopic images show neuronal labels by Nissl staining in the hippocampus after treatment with and without SZRD for 4 weeks (× 400 magnifications; scale bar represents 50 µm). b The neuronal number in the regions of CA1 and CA3. c The neuronal number in the regions of CA4 and DG. The data are presented as mean ± SEM (n = 4 in each group). **P < 0.01 vs. Control group; ^#P < 0.05 and ^##P < 0.01 vs. Model group
