作者用142只雄性Long-Evans大鼠分A、B两组进行微波(2.45 GHz)照射实验。A组每天照射1小时,微波功率密度(PD)为1～70mw/cm~2;B组每天照射4小时,PD为0.1～40mw/cm~2。动物间所受辐射的功率密度变动小于10%。微波平均吸收比率(SAR)是0.21±0.01(SE)w·kg~(-1)·mw~(-1)·cm~2。用放射免疫法测定促甲状腺激素(TSH),用竞争蛋白粘合物测定皮质酮(CS),体温(Tcol)则为直接测定结肠温度。实验结果表明,大鼠结肠温度随微波照射功率的增大而增加,照射时间如超过1小时,大鼠结肠温度的增加与照射微波的时间无关,A、B两组之间无区别;大鼠皮质酮亦随着照射微
The authors used 142 male Long-Evans rats were divided into A, B two groups of microwave (2.45 GHz) irradiation experiments. Group A received daily irradiation for 1 hour and microwave power density (PD) was 1 ~ 70 mW / cm ~ 2. Group B received daily irradiation for 4 hours and PD was 0.1 ~ 40 mW / cm ~ 2. The variation in the power density of the animals exposed to the animals is less than 10%. The average microwave absorption ratio (SAR) was 0.21 ± 0.01 (SE) w · kg -1 · mw -1 · cm -2. Thyrotropin (TSH) was measured by radioimmunoassay and corticosterone (CS) was measured with competing protein binding. The temperature of the colon (Tcol) was measured directly for the colonic temperature. The experimental results showed that the temperature of colon in rats increased with the increase of microwave irradiation power. The irradiation time was longer than 1 hour. The increase of colonic temperature had no relation with the time of microwave irradiation. There was no difference between A and B groups. Corticosterone also with micro-irradiation
