【摘要】：随着科技的发展和人们生活水平的提高,电子产品的大量生产与使用,加上城市化的快速发展,变压器和高压输电线分布广泛。人们生活环境充满着电磁辐射,越来越多的居民担心电磁辐射对他们健康有影响,这一问题成为当今全球热点问题之一,受到越来越多的关注,到底环境中的电磁辐射对人体有没有影响,这种影响是正面还是负面的,现在国内外许多学者正潜心研究。本论文高血脂大鼠组织的物理特性,主要研究的物理特性有红外光谱特性,荧光光谱特性和电学特性等。从实验上研究了极低频电磁场和红外场暴露作用前后高血脂大鼠不同组织的物理特性的变化,分析了不同类型电磁辐射暴露作用对于高血脂大鼠的影响,本论文的主要工作概括为以下几部分：第一,建立了高血脂模型大鼠,通过总胆固醇和甘油三酯等生化指标的测量结果验证了模型建立的成功。对于高血脂模型大鼠和对照组大鼠的血液流变学特点,傅里叶变换红外光谱特点,荧光光谱特点和电学特性进行了测量。并进行了讨论分析,研究不同物理角度上高血脂大鼠与正常组大鼠的不同。第二,研究了极低频电磁场暴露的高血脂大鼠部分活性组织(睾丸、肝、血清、脑)的电学特性,讨论了血液、神经和生殖系统的影响,进一步分析了极低频电磁场暴露对生物机体的作用机制；研究了极低频电磁场对高血脂大鼠血清的傅里叶变换红外光谱和荧光光谱的影响,检验采用光谱技术检测高血脂症方法的可行性。极低频电磁场暴露后,高血脂大鼠血脂有一定程度的降低,而且降低高血脂电磁场辐照组血液的相对介电常数增加导电率,但是本实验采用的极低频电磁场对神经系统和生殖系统没有影响。第三,研究了红外场暴露的高血脂大鼠部分活性组织(睾丸、肝、血清、脑)的电学特性,并将之与对照组进行了分析比较,探讨了红外场暴露作用对于血液、神经和生殖等系统可能存在的一些影响。红外场暴露后高血脂大鼠血脂降低,降低血液的相对介电常数增加导电率,而对神经系统和生殖系统没有影响。
[Abstract]:With the development of science and technology and the improvement of people's living standard, the mass production and use of electronic products, coupled with the rapid development of urbanization, transformers and high-voltage transmission lines are widely distributed. The living environment of people is full of electromagnetic radiation. More and more residents are worried about the impact of electromagnetic radiation on their health, which has become one of the hot issues in the world today, and has attracted more and more attention, whether the electromagnetic radiation in the environment has any impact on the human body. Whether this effect is positive or negative, many scholars at home and abroad are now focused on the physical characteristics of hyperlipidemia rat tissue, the main physical characteristics of the infrared spectrum. The changes of physical properties of hyperlipidemia rats before and after exposure to very low frequency electromagnetic field and infrared field were studied experimentally. The effects of different types of electromagnetic radiation exposure on hyperlipidemia rats were analyzed. The main work of this paper is summarized as follows: First, the model of hyperlipidemia was established in rats. The success of the model was verified by measuring the biochemical indexes such as total cholesterol and triglyceride. The characteristics of hemorheology in hyperlipidemia model rats and control rats were analyzed by Fourier transform infrared spectroscopy (FTIR). The characteristics of fluorescence spectra and electrical properties were measured, and the differences between hyperlipidemia rats and normal rats from different physical angles were discussed and analyzed. Secondly, the electrical properties of some active tissues (testis, liver, serum, brain) of hyperlipidemia rats exposed to very low frequency electromagnetic field were studied, and the effects of blood, nerve and reproductive system were discussed. The mechanism of the effects of very low frequency electromagnetic field exposure on biological organism was further analyzed. The effect of very low frequency electromagnetic field on Fourier transform infrared spectroscopy and fluorescence spectrum of serum of hyperlipidemia rats was studied, and the feasibility of using spectrum technique to detect hyperlipidemia was examined. The blood lipid of hyperlipidemia rats was decreased to a certain extent, and the relative dielectric constant of the hyperlipidemic electromagnetic field irradiation group increased the conductivity. But the very low-frequency electromagnetic fields used in this study have no effect on the nervous system and reproductive system. Thirdly, the electrical properties of some active tissues (testis, liver, serum, brain) of hyperlipidemia rats exposed to infrared field were studied and compared with the control group. The possible effects of infrared field exposure on blood, nerve and reproductive systems were discussed. After infrared field exposure, blood lipids in hyperlipidemia rats were decreased, and the relative dielectric constant of blood was decreased to increase electrical conductivity. It has no effect on the nervous system and the reproductive system.
