【摘要】 用ＶＤＴ脉冲磁场、磁通密度峰值４０μＴ和４μＴ（时间导数３．３Ｔ／ｓ和０．３３Ｔ／ｓ）对怀孕小鼠整个孕期进行辐射，每天５小时，每周６天。结果得出：与假辐射组比较，高强度组仔鼠下丘脑琥珀酸脱氢酶活性显著下降（Ｐ＜０．０１），但低强度组的下降无显著性（Ｐ＞０．０５）。更多还原

【Abstract】 Impregnated NIH mice were exposed to VDT pulse magnetic field 5 hrs daily 6 days a week at 0,4 and 40μT peak to peak(dB/dT:0,0.33,and 3.3T/s respectively)until the offsprings were delivered.Succinate dehydrogenase(SDH)in hypothalamus of newborn offsprings was examined by Nachles’s method.The result showed that in high intensity field group(40μT)SDH activities in exposed animals decreased significantly as compared with the control(sham exposed)(P<0.01),but there was no statistical significance(P>0.05)in the low ones(4μT).更多还原
