Figure 1

Hematoxylin and eosin (HE) staining of representative sections of hippocampal CA1 region under a 400x light microscopy (scale bar = 25 μm); the karyopyknosis in the model group was marked with arrows. (a–e) HE staining of representative sections of the model, control, PNS high-dosage, PNS low-dosage, and Hup A (positive control) group, respectively; (f) neuronal numbers of each section were quantitatively analyzed in 10 high powered fields (HPF, 400x) using Imaging-Pro-Plus software 6.0. Data represent mean ± SD from 4-5 independent samples. Statistically significant differences were calculated by one-way ANOVA using the SPSS 13.0 software. , versus control group; , , versus model group.
