【摘要】 目的探讨出生前1800MHz微波辐射对大鼠学习和空间记忆行为的影响。方法用功率为1800MHz密度为0.5mW/cm2的微波于大鼠孕期0～20d全身连续照射,同时设置对照组。用Morris水迷宫对10周龄F1代仔鼠进行学习和空间记忆功能的测定。结果暴露组与对照组在学习记忆功能上差异无显著性(P>0.05),但暴露组在空间定位上有性别差异,雌鼠能力较雄鼠差,P<0.05。结论该次实验没有发现1800MHz射频场暴露对10周龄F1代仔鼠的学习和空间记忆有影响。更多还原

【Abstract】 Objective To study the effects of prenatal exposure to1800MHz radiofrequency field on learning and spatial memory in ratsoffspring.Methods The pregnant rats and control group were generally and continuously radiated by1800MHz microwave radiation with power density of0.5mW/cm 2 respectively.The capability of learning and spatial memory of off-spring aged10weeks were tested by Morris maze test.Results No significant differences in capability of learning and memory were observed between exposure group and control group(P>0.05).But the female offspring in exposure group showed weaker capability of spatial location compared with that of male offspring in exposure group(P<0.05).Conclusion The affect of pre-natal exposure to1800MHz radiofrequency field to the capability of learning and spatial memory in offspring aged10weeks was not observed.更多还原
