In recent years, high-power microwave (HPM) technology has developed rapidly. However, the current research mainly focuses on how to improve its performance and its impact on electronic devices, and there has been relatively little research on its effects on organisms. In particular, the research on the biological effects of HPMs in the X-band is even more limited. The purpose of this paper is to conduct a study on the effects of HPMs in the X-band with a frequency of 9.375 GHz on mood, learning, and cognitive abilities, as well as the antioxidant defense system. Upon observation, it was noted that the mice in the exposed groups, when compared to the control group, did not display significant signs of depression or anxiety. Furthermore, their learning capabilities, memory retention, and cognitive functions remained intact and were not adversely affected. The results of oxidative-stress-related indicators in serum and brain tissue showed increased levels of antioxidant enzymes including superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px), reduced levels of protein carbonyl (PCO) and malondialdehyde (MDA), and no significant changes in reactive oxygen species (ROS). In summary, acute exposure to 9.375 GHz HPM did not cause significant damage to the organisms, and the body could defend against the acute stress caused by HPMs through its own antioxidant system. This investigation provides substantial theoretical foundations and robust experimental evidence for establishing safety parameters and potential biomedical applications of microwave radiation within defined exposure limits.
近年来,高功率微波(HPM)技术发展迅速。然而,目前的研究主要集中在如何提高其性能以及对电子设备的影响,而对其对生物体的影响研究相对较少。特别是,关于X波段高功率微波生物效应的研究更为有限。本文旨在研究频率为9.375GHz的X波段高功率微波对情绪、学习和认知能力以及抗氧化防御系统的影响。经观察发现,与对照组相比,暴露组小鼠未表现出明显的抑郁或焦虑迹象。此外,它们的学习能力、记忆保持能力和认知功能保持完好,未受到不利影响。血清和脑组织中氧化应激相关指标的结果显示,超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和谷胱甘肽过氧化物酶(GSH-Px)等抗氧化酶水平升高,蛋白质羰基(PCO)和丙二醛(MDA)水平降低,活性氧(ROS)无显著变化。综上所述,急性暴露于9.375GHz高功率微波不会对生物体造成显著损害,机体可通过自身的抗氧化系统抵御高功率微波引起的急性应激。本研究为在规定暴露限值内建立微波辐射的安全参数和潜在生物医学应用提供了坚实的理论基础和有力的实验证据。
