TUNEL staining to detect apoptosis of hippocampal CA1 region (Hippo) and prefrontal cortical (PFC) neurons in rats of each group. (a) Apoptotic cells in Hippo and PFC detected by TUNEL staining. Scale bar = 20 μm. (b) Comparison of apoptotic neurons number in Hippo and PFC in each group of rats (n=6). Data was shown as Mean±SD. P<0.05 vs control group; P<0.05 vs AD model group.
