| 摘 要： | 目的 评价5月龄APP/PS1双转基因小鼠学习记忆功能及脑部病理改变。方法 5月龄APP/PS1（+/-）小鼠，采用Morris水迷宫实验评价空间学习记忆功能，免疫组织化学和刚果红染色观察淀粉样斑块沉积情况。结果 Morris水迷宫实验显示APP/PS1（+）小鼠逃避潜伏期明显长于APP/PS1（-）小鼠，表明5月龄APP/PS1（+）小鼠已经出现了空间学习记忆功能的损害。新物体识别实验中5月龄APP/PS1（+）小鼠对新物体的分辨指数无显著降低，免疫组化、刚果红染色显示5月龄APP/PS1（+）小鼠海马及皮质均出现斑块沉积。结论 5月龄APP/PS1双转基因小鼠出现空间学习记忆功能损害，小鼠脑内已经出现相应的病理改变。 |

| Abstract: | Objective To explore behavior related to learning and memory ability of 5-month-old APP/PS1 double transgenic mice and pathology in the brain. Methods Five-month-old APP/PS1(+/-) double transgenic mice were tested with Morris water maze. β-amyloid plaques were studied with immunohistochemical staining and Congo red staining to observe-amyloid plaques deposition. ResultsAPP/PS1(+) mice escape latency was significantly longer than that of APP/PS1(-) mice, 5-month-oldAPP/PS1(+) mice learning and memory ability were damaged. β-amyloid plaques immunohistochemical staining and Congo red staining showed senile plaques in 5-month-old APP/PS1(+) mice. Conclusion Five-month-old APP/PS1 (+) mice learning and memory ability were damaged, a part of Alzheimer disease pathology was shown in the brain of 5-month-old APP/PS1(+) mice. |
