ABSTRACT

Objective To establish rat models with Alzheimer's disease(AD) induced by ?-amyloid,and to observe the effects of nicotine on learning and memorizing ability of the rats. Methods Aggregated A?1-40 was injected into the bilateral basal forebrain of the rats.Learning and memorizing ability of the rats were inspected through Morris water maze test.The effects of nicotine on learning and memorizing ability of the rats induced by ?-amyloid peptide were observed. Results The learning and memorizing ability of AD animal models injected aggregated(A?1-40) for 2 weeks decreased(P
