摘要
目的通过研究补肾祛瘀化痰法对ApoE基因敲除小鼠Morris水迷宫成绩的影响,探讨补肾祛瘀化痰法对认知功能障碍的改善作用。方法将ApoE基因敲除小鼠共32只随机分为成年中药组、成年模型组及老年中药组、老年模型组,并取相同遗传背景的C57BL/6J小鼠共16只随机分成成年正常组及老年正常组,连续给予补肾祛瘀化痰法组方灌胃12周,成年组至32周龄、老年组至44周龄时检测Morris水迷宫定位航行实验及空间探索实验的成绩。结果定位航行实验逃避潜伏期结果不符合正态分布,故采用非参数检验中K组独立样本检验进行数据统计:成年各组之间逃避潜伏期无明显差异(P>0.05)。老年模型组较老年中药组逃避潜伏期显著延长(P<0.01),老年模型组较老年正常组亦明显延长(P<0.05)。空间探索实验中,第Ⅲ象限路程及第Ⅲ象限时间均符合正态分布,故采用单因素方差分析进行数据统计:成年各组之间在穿台次数、第Ⅲ象限路程及第Ⅲ象限时间均无明显差异(P>0.05);老年模型组较老年正常组穿台次数明显减少(P<0.05),老年中药组及老年模型组均较老年正常组在第Ⅲ象限路程及第Ⅲ象限时间明显缩短(P<0.05)。结论老年中药组及老年正常组小鼠Morris水迷宫成绩较理想,说明补肾祛瘀化痰法可改善老龄小鼠Morris水迷宫成绩,从而改善认知功能。
Objective To assess the effects of tonifying kidney and remoling stasis and phlegm on the test of morris water maze of ApoE knockout mice in adult and old groups. Methods ApoE knockout mice were dilided into adult treatment group, adult model group, old treatment group and old model group. And C57BL/6J mice were dilided into adult normal groups and old normal groups. When the adult groups mice were 32 weeks and the old groups were 44 weeks, the mice were tested by morris water maze. The scores of naligation experiment and space exploration experiment in morris water maze were recorded. Results The escape latency of adult rats in the treatment group, model group and normal group had no significantly difference（P＆gt;0. 05）. But in old rats, the escape latency of the model group was significantly longer than that of the normal group and treatment group. The space exploration experiment showed that the normal group was much better than the treatment and model groups. Conclusions The normal group and the treatment group show better scores in morris water maze than the model group. The results support that tonifying kidney and remoling stasis and phlegm can improle cognitile function of old ApoE knockout mice.
