摘要: 目的 了解老年痴呆模型大鼠海马及嗅球中胶质纤维酸性蛋白(GFAP)和神经元特异性烯醇化酶(NSE)表达的差异,从而了解嗅觉与老年痴呆的关系。方法 成年SD大鼠,通过向大鼠侧脑室内注射Aβ建立模型后用免疫组化方法检测海马及嗅球中GFAP和NSE的表达,并对嗅球中两者蛋白水平表达的变化进行初步的检测。结果 通过比较模型组与对照组海马及嗅球组织,模型组GFAP的表达显著增加,而NSE的表达则降低。结论 老年痴呆大鼠模型组与对照组嗅觉系统内GFAP和NSE蛋白表达存在显著性差异。

Abstract: Objective To find out the difference expression of glial fibrillary acidic protein and neuron-specific enolase in hippocampi and olfactory bulb of model rats of Alzheimer's disease , consequently to find out the relationship between olfactory and Alzheimer's disease. Methods Adult rats, the expression of GFAP and NSE in hippocampi and olfactory bulb was measured by using immuhistochemical after a single intracerebroventricular injection of β-amyloid peptide , and change of this two protein in olfactory .Result comparing the hippocampi and olfactory between model and control team, the expression of GFAP in model team increasing evidently, the expression of NSE descending however. Conclusion there is observably difference in olfactory system between model and control group in Alzheimer's disease rats.

Key words: model rats of Alzheimer’s disease Rats, Olfactory bulb, hippocampi, glial fibrillary acidic protein, neuron-specific enolase.
