2、脑电图(EEG)、肌电图(EMG)2及体温等指标进行检测。结果7和11mW/cm组EEG见D频段相对功率谱分别于辐射后7d和14d内显著升22高,而B频段相对功率谱均于辐射后3d内明显下降,14d见升高,30d见部分恢复。2mW/cm和5mW/cm组D2频段与B频段相对功率谱辐射后未见明显变化。11mW/cm组心率于辐射后即刻明显减慢、心电图R波和T波波幅均于辐射后1d内显著降低,且心律不齐,30d时基本恢复。辐射后即刻至30d,各实验组猕猴的体温及肌电均22无明显改变。结论7和11mW/cm微波辐射可引
3、起猕猴脑电生理功能损伤,且与辐射剂量呈正相关;11mW/cm2微波辐射可引起猕猴心脏电生理功能损伤;2~11mW/cm微波辐射对猕猴体温及肌电均无明显影响。[关键词]微波;猕猴;生理功能;脑电图;心电图[中图分类号]X591[文献标志码]A[文章编号]1674-9960(2011)05-0355-06Effectsofmicrowaveradiationonphysiologicalfunctionsofimportantorgansinrhe-susmonkeysXUXin-ping,WANGShao-
