非均匀恒磁场对小鼠学习记忆能力的影响

The effect of non-uniform-permanent magnetic field on learning and memory in mice

目的探讨非均匀恒磁场N、S极对小鼠学习记忆的影响。方珐用避暗实验法和自主活动法，分别观察非均匀恒磁场N、S极对学习记忆能力的影响；应用光镜观察非均匀恒磁场N、S极治疗后，脑组织神经元细胞形态学改变。结果避暗实验表明磁场N极组与空白对照组比较，学习成绩测试错误次数(mistake，M值)减少，记忆测试M值减少，均有显著性差异(P＜0．05)；磁场S极组与空白对照组比较，记忆测试M值减少，有显著性差异(P＜0．05)；小鼠自主活动测定各组均无显著性差异(P＞0．05)；各组比较脑神经元的结构无明显改变。结论非均匀恒磁场的预防性治疗，可提高小鼠的学习记忆能力，并以N极为著。

Objective To investigate the effect of N?S poles of non uniform permanent magnetic field on learning and memory in mice.Methods The step through test and independence activity were used in the observation of effect of non uniform permanent magnetic field on learning and memory while the optical microscope was used to observe the hostomorphological changes in the neurons of the brain tissues.Results The step through test indicated that by comparison with the blank control group,the mistakes in the e...
