Abstract:
Objective To establish the rat model of type 2 diabetes mellitus (T2DM)-induced Alzheimer’s disease (AD).Methods The rat model of T2DM was established by continuous high fat and high glucose diet in aged rats. Then the rat model was screened and identified by using Morris water maze, cerebrospinal fluid microdialysis technique,ELISA,electrophysiological technique and pathologic method,respectively.Results Compared with the normal group and the T2DM group,the rats in T2DM+DM group had obviously learning and memory impairment;the level ofβ-AP in the hippocampus was significantly higher and the frequency of the spikes induced by Achin the hippocampus was notably lower.Conclusion The rat model of T2DM-induced AD can be successfully established by continuous high fat and high glucose diet in rats.
