磁场作用对小鼠抗应激能力的影响

Effect of Magnetic Field on the Anti-stress of Mice

目的 :探讨磁场作用对小鼠抗应激能力的影响。方法 :对磁场处理 30分钟和 1 5分钟的两组实验组与非磁场处理的正常对照组进行游泳耐疲劳运动时间的比较。结果 :游泳耐疲劳运动实验表明 30分钟磁场处理组与正常对照组比较 ,动物游泳耐疲劳运动时间延长 ,且具有显著性差异 (p <0 .0 5 ) ;1 5分钟磁场处理组与正常对照组比较 ,动物游泳耐疲劳运动时间无明显差异 (p >0 .0 5 ) ;30分钟磁场处理组与 1 5分钟磁场处理组比较 ,动物游泳耐疲劳运动时间延长 ,且具有显著性差异 (p <0 .0 5 )。结论 :在一段时间( 30天 )内 ,每天给予小鼠 30分钟的磁场处理明显提高了小鼠的抗应激能力 ,而磁场处理 1 5分钟对小鼠的抗应激能力不产生影响。

Objective: To discuss the effects of magnetic field on the anti-stress of mice. Methods: Kun-ming mice were divided into three groups: 30 min. exposure of magnetic field group, 15 min. exposure of magnetic field group and control group. The change of anti-tire swimming time of mice were respectively observed after 15 min. or 30 min. exposure of magnetic field per day standing for 30 days. Results: Compared with control group, the anti-tire swimming time of 30 min. exposure of magnetic field group mice was increased(p<0.05); the 15 min. exposure of magnetic field group mice were no significant difference(p>0.05). Conclusion: The biological effect of the magnetic field on anti-stress capability of mice is differently and 30 min. exposure of magnetic field per day standing for 30 days improves the anti-stress capability of mice.
