Objective: To explore effects of Ganoderma lucidum polysaccharides(GLP) on synapsis and hippocampal synaptophysin expression in AD-rats. Method: AD-rats induced by Aβ25-35 were treated with different concentrations of GLP for 7 days. The Morris water maze was applied to validate the learning and memory ability in rats. The expression of synaptophysin and the alleosis of synaptic stereology were detected on tissues of CA1 and CA3 regions in hippocampus by immunohistochemitry method
transmission electron microscope (TEM) and image-analysis system. Result: Compared with the model group
GLP (75
50 mg ·kg-1) decreased the average delitescence of rats in Morris water maze
and GLP increased the synaptophysin expression levels (P<0.01)and numerica density(Nv)
surface density(Sv) (P<0.01
P<0.01). Conclusion: GLP improves the learning ability in AD-rats. Reversal of synaptophysin and Nv
Sv on hippocampus could be contributed to the mechanism.
