恒定磁场对小鼠抗应激能力的影响

The Effect of Stable Magnetic Field on the Anti-stress of Mice

通过对三组恒定磁场作用4 h、3 h和2 h动物与对照组动物(无外加磁场作用)进行游泳耐疲劳运动时间的比较,探讨恒定磁场对小鼠抗应激能力的影响.结果发现,3 h或4 h恒定磁场作用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<0.05);2 h恒定磁场作用组与正常对照组比较,动物游泳耐疲劳运动时间无显著性差异(P>0.05).说明给小鼠一定时间的恒定磁场作用能明显提高小鼠的抗应激能力,作用过长时间虽然能提高抗应激能力,但对小鼠的伤害较大.

To discuss the effect of stable magnetic field on the anti-stress of mice, the change of anti-tire swimming time of mice were respectively observed after a 20-day exposure of 2hs, 3hs or 4hs of stable magnetic field per day. The test showed that the anti-tire swimming time of 3h or 4h exposure of stable magnetic field group mice was increased （P〈0.05） while no significant difference （P〉0.05） could be found in the group of mice with 2h exposure of stable magnetic field, compared with the control group. The result indicated that 3h exposure of stable magnetic field per day standing for 20 days improves the anti-stress capability of mice and 4h exposure of stable magnetic field has a fatal effect on mice.
