The effects of Xiaoyaosan on hippocampal neurons were measured using Cresyl violet staining. (A) Representative micrographs of the CA1, CA3 and DG regions of the hippocampus. The first row of micrographs was captured at low magnification under a light microscope (scale bar = 200 μm, 100 × magnification); the remaining micrographs were captured at higher magnification under a light microscope (scale bar = 50 μm, 400 × magnification). (B) Quantitative analysis of the numbers of Cresyl violet-stained neurons in the hippocampal CA1, CA3 and DG regions. Values are presented as the means ± SEM from 5 rats in each group. *P < 0.05 or **P < 0.01 versus the control group. Δ P < 0.05 versus the vehicle (distilled water) group. # P < 0.05 versus the vehicle (dissolvent) group.
