目的:由于高频辐射技术的大量应用,从业人员逐渐增多,高频辐射对人体健康的影响正成为一个刻不容缓亟待解决的问题。据大量文献报道,高频辐射可使生物体多个系统及器官受损,海马组织更是非常敏感。参力胶囊有提高机体免疫力的功效。它对高频辐射导致睾丸等其他组织器官的损伤具有明显的防治作用。参力胶囊,主要成份为黄芪%人参%灵芝孢子粉,有增强免疫力,抗辐射的功用,是一种无毒副作用的纯中药制剂。有研究表明,参力胶囊对辐射损伤造成的造血功能障碍有修复作用,并对辐照中的胸腺和脾脏有一定的保护作用。血脑屏障是介于血液和脑组织之间,对物质通过有选择性阻挡作用的动态界面。其发挥功能的结构基础是脑毛细血管内皮细胞及其间的紧密连接。方法:选用成年,雄性SD大鼠40只,随机分为对照组、非防护辐照组、高剂量药物防护组、低剂量药物防护组,每组10只。选用高功率、大剂量、长时间连续的辐照源对实验动物进行定位辐照。采用以硝酸镧为通透性示踪剂,在透视电镜下观察海马区血脑屏障通透性及超微结构。结果:镧颗粒平均直径为0.4×10-9m,通常情况下,它不能通过细胞间的紧密连接,无法通过细胞膜上平均直径仅1.8×10-11m的小孔。仅滞留于毛细血管腔内,不能透过血脑屏障。但本课题采用的是高功率、大剂量、长时间连续照射,如果镧颗粒突破了血脑屏障,则说明此电磁辐射发射的功率能使大鼠血脑屏障的结构遭到破坏,通透性升高,从而证实海马区域受损,导致大鼠行为学发生改变。结论:通过探索高频辐射对生物体的损伤效应及防护方法,来总结高频辐射对人体的损伤及如何预防,摸索总结出一套适合我国高频辐射工作场所防护的有效方案,完善我国在该领域的研究,真正解决高频辐射工作场所工作人员最为关心的问题,减少高频辐射对他们身体的伤害,提高他们的工作实力及效率。
Objective: Due to the large number of applications of high-frequency radiation technology, practitioners gradually increased, the impact of high-frequency radiation on human health is becoming an urgent problem to be solved. According to a large number of literature reports, high-frequency radiation can damage multiple systems and organs of the organism, hippocampus is more sensitive. Samsong capsules have the effect of improving the body’s immune system. It is high-frequency radiation lead to testicular and other tissues and organs damage has obvious prevention and treatment. Samson capsule, the main ingredient of Astragalus% ginseng% fungus spores powder, enhance immunity, anti-radiation function, is a non-toxic side effects of pure Chinese medicine. Studies have shown that Shen-Li Capsule on radiation-induced hematopoietic dysfunction repair, and radiation in the thymus and spleen have a protective effect. The blood-brain barrier is a dynamic interface between blood and brain tissue that selectively blocks the passage of matter. The structural basis for its functioning is the brain capillary endothelial cells and the tight junctions between them. Methods: Forty adult male Sprague-Dawley rats were randomly divided into control group, unprotected irradiation group, high dose drug protection group and low dose drug protection group, with 10 rats in each group. Selection of high-power, high-dose, long-term continuous irradiation of irradiated animal experimental location. Lanthanum nitrate was used as a permeable tracer to observe the permeability and ultrastructure of the blood-brain barrier in the hippocampus under fluoroscopy. Results: The mean diameter of lanthanum particles was 0.4 × 10-9m. Under normal circumstances, lanthanum particles could not pass the tight junction between cells and could not pass through the pores of the cell membrane with an average diameter of only 1.8 × 10-11m. Only stay in the capillary cavity, can not penetrate the blood-brain barrier. However, the subject used high-power, high-dose, continuous irradiation for a long time, if the lanthanum particles break through the blood-brain barrier, the power of the electromagnetic radiation emitted can damage the structure of the blood-brain barrier in rats, permeability Rise, thus confirming the damaged area of the hippocampus, resulting in behavioral changes in rats. Conclusion: By exploring the effect of high-frequency radiation on organism damage and protection methods, this paper summarizes the high-frequency radiation on the human body damage and how to prevent and explore a set of effective programs for China’s high-frequency radiation workplace protection, improve our The research in this field really solves the most concerned problems of staff in high-frequency radiation work places, reduces the harm of high frequency radiation to their bodies and enhances their working strength and efficiency.
