50Hz磁场照射对小鼠嗅觉辨别能力的影响

Effect of exposure to 50 Hz magnetic field on olfactory discrimination in mice

摘要: 目的:探讨长期磁场暴露对成年小鼠嗅觉辨别功能的影响。方法:采用习惯化-去习惯化模型,连续20d每天1h的1mT、50Hz磁场照射小鼠,观察对小鼠嗅觉辨别功能的影响。采用旷场行为检测小鼠的活动量和探究行为。结果:连续20d每天1h的1mT、50Hz磁场照射后,小鼠的运动能力、探究能力及嗅觉辨别功能没有显著性变化。结论:连续20d每天1h的1mT、50Hz磁场照射不影响嗅觉辨别能力。

Abstract: Objective:To investigate whether chronic exposure to extremely low frequency magnetic field(ELF-MF)(50 Hz) can influence olfactory discrimination in mice.Methods:A habituation-dishabituation pattern was used to study olfatory discrimination in mice following exposure to 50 Hz magnetic field of 1 mT(1 hour/day) for 20 days.The motor behavior(locomotion)and exploring behavior were detected by open field test.Results:After exposure to 50 Hz magnetic field of 1 mT(1 hour/day) for 20 days,there were no significant differences about motor behavior(locomotion),exploring behavior and olfactory discrimination in mice.Conclusions:Exposure to chronic ELF-MF has no effect on olfactory discrimination in mice.
