【摘要】 目的 观察补肾化痰法对AD模型大鼠行为学的影响并探讨其可能机制。方法 应用脑立体定向技术给大鼠BNM注射凝聚态Aβ2535＋IBO构建AD模型。注射2周后，高、中、低量组分别给大鼠该药水煎液灌胃；西药组用哈伯因混悬液灌胃；正常组、空白组、模型组均给予等容积的生理盐水灌胃。28 d后采用Morris 水迷宫进行行为学评价。结果 行为学结果显示高、中、低量组和西药组的平均潜伏期较模型组有明显缩短（P<0.01）；高、中量组的象限百分比较模型组有明显提高（P<0.01），20 %、40 %区域较模型组有明显减少（P<0.01）；模型组大鼠空间探索的象限百分比和跨过原平台位置次数比正常组和空白组明显降低（P<0.01）。西药组和高、中、低量组的象限百分比和跨过原平台位置次数较模型组有明显提高（P<0.01），并呈现一定量效关系（P<0.01）。结论 补肾化痰法可显著改善AD模型大鼠的学习记忆障碍。

【Abstract】 Objective To observe effects and function mechanism of replenishing kidneyessence and removing phlegm therapy on behavior in the rat of AD.Methods Application of technology to stereotactic brain of rats injected BNM condensed Aβ2535 + IBO build AD model. 2 weeks after injection, high, medium and low volume of the rats were administered the drug decoction; western medicine group with Huperzine oral suspension; normal group, blank group, model group were given equal volume of normal saline ig. 28 days after the Morris water maze used for behavioral evaluation.Results Behavioral results showed high, medium and low volume group and western medicine group than the average incubation period of the model group was significantly shorter (P<0.01); high percentage of the volume group than the quadrant of the model group had markedly improved (P<0.01), 20 %, 40% than the region has significantly reduced the model group (P<0.01); model group the percentage of space exploration and the quadrant across the former platform position than the normal group and blank group were significantly lower (P<0.01). Western medicine group and the high, medium and low percentage and crossed the quadrant the original platform lo [1] [2] [3] [4] [5] 下一页 |
