本文以7mW/cm~2（SAR=7.7mW/g）功率密度的3GHz脉冲波辐射青年昆明杂种小鼠（下同）（9～10周龄）60min/day，连续2天。辐射后第3天作绵羊红细胞（SRBC）免疫，第7天作血细胞凝集素效价（HAT）测定，有增加倾向，第8天达高峰（P＜0.01），第9天开始回降，第22天恢复到对照组水平，显示微波辐射对小鼠的免疫机能有短暂的增强作用。以1、5、7和12mW/cm~2不同功率密度（SAR分别为1.1、5.5、7.7和13.2mW/g）的微波辐射青年鼠，辐射与免疫条件同上，1mW/cm~2组小鼠的HAT无甚差异，5mW/cm~2组增加非常显著（P＜0.005），7mW/cm~2组增加最为显着（P＜0.001），12mW/cm~2组增加亦显著（P＜0.005），但比7mW/cm~2组为低。以5mW/cm~2相同功率密度的微波，辐射不同年龄小鼠（幼、青和成年鼠的SAR分别6、5.5和4.5mW/g），辐射与免疫条件同上，幼年鼠（4～5周龄）的HAT差异不显著，而青年与成年鼠（16周龄以上）明显增加（P＜0.005），尤以成年鼠增加为显著。
In this paper, young Kunming hybrid mice (the same below) (9 to 10 weeks old) were irradiated with 3GHz pulsed wave with power density of 7mW / cm 2 (SAR = 7.7mW / g) for 60min / day for 2 days. Sheep erythrocytes (SRBC) were immunized on the third day after radiation and hemagglutinin titer (HAT) was measured on the seventh day. The hemagglutination rate increased on the eighth day (P <0.01) 22 days returned to the control group level, showing that microwave radiation has a transient enhancement of the immune function in mice. The young mice were irradiated with microwaves with different power densities (SAR of 1.1, 5.5, 7.7 and 13.2 mW / g) at 1,5,7 and 12 mW / cm ~ 2, respectively. (P <0.001). The increase of 5mW / cm ~ 2 group was the most significant (P <0.005), the increase of 7mW / cm ~ 2 group was the most significant (P <0.001) ), But lower than 7mW / cm ~ 2 group. At 5 mW / cm ~ 2, the mice of different ages (6,5.5 and 4.5 mW / g SAR, respectively) were irradiated with microwave at the same power density. The radiation and immune conditions were the same as above. HAT difference was not significant, while young and adult rats (16 weeks and above) increased significantly (P <0.005), especially in adult rats increased significantly.
