摘　　要：本实验应用频率为36.04及50.05GHz,功率密度为1mW/cm^2的毫米波,照射小鼠腹部体表,发现低功率毫米波辐射对小鼠肝脏有间接作用。应用透射电镜及电镜细胞化学技术观察发现,肝细胞超微结构呈轻微可逆性损伤,G-6-P酶含量增多;应用扫描图象分析仪(TAS)对组织化学染色的肝组织切片进行DNA定量,发现DNA含量无显著性变化。通过动态观察表明,两种不同频率的毫米波对肝细胞的影响不同,线粒体及G-6-P酶对36.04 GHz的毫米波较敏感,而内质网对50.05GHz的毫米波较敏感。根据实验结果,本文对毫米波特异性效应的机理进行了探讨,指出该效应可能是通过神经-体液系统介导的。The biological effects of 36.04 GHz and 50.05 GHz millimeter wave radiation at low power density (1 mW/cm2) on BALB/c liver were studied. The abdominal local surface of the mice was exposed to millimeter waves for 30 minutes daily for 6 days. The results indicate that the millimeter waves have indirect effects on the liver cells. The ultrastructural examination discovered reversible injuries. G-6-Pase was increased after radiation at the 3rd and 5th days. No change was found in DNA content of the liver cells. Meanwhile, it was also found that mitochondria and G-6-Pase were relatively sensitive to 36.04 GHz millimeter wave and endoplastic reticula were relatively sensitive to 50.05 GHz millimeter wave. The changes were found to have dynamic processes 7 days after radiation. From these results and the literature, it is concluded that the indirect specific biological effects of millimeter waves at low power densities are caused by neuronic and humoral systems.
