【摘要】：隨著科技的發(fā)展和人們生活水平的提高,電子產(chǎn)品的大量生產(chǎn)與使用,加上城市化的快速發(fā)展,變壓器和高壓輸電線分布廣泛。人們生活環(huán)境充滿著電磁輻射,越來越多的居民擔心電磁輻射對他們健康有影響,這一問題成為當今全球熱點問題之一,受到越來越多的關注,到底環(huán)境中的電磁輻射對人體有沒有影響,這種影響是正面還是負面的,現(xiàn)在國內外許多學者正潛心研究。本論文高血脂大鼠組織的物理特性,主要研究的物理特性有紅外光譜特性,熒光光譜特性和電學特性等。從實驗上研究了極低頻電磁場和紅外場暴露作用前后高血脂大鼠不同組織的物理特性的變化,分析了不同類型電磁輻射暴露作用對于高血脂大鼠的影響,本論文的主要工作概括為以下幾部分： 第一,建立了高血脂模型大鼠,通過總膽固醇和甘油三酯等生化指標的測量結果驗證了模型建立的成功。對于高血脂模型大鼠和對照組大鼠的血液流變學特點,傅里葉變換紅外光譜特點,熒光光譜特點和電學特性進行了測量。并進行了討論分析,研究不同物理角度上高血脂大鼠與正常組大鼠的不同。 第二,研究了極低頻電磁場暴露的高血脂大鼠部分活性組織(睪丸、肝、血清、腦)的電學特性,討論了血液、神經(jīng)和生殖系統(tǒng)的影響,進一步分析了極低頻電磁場暴露對生物機體的作用機制；研究了極低頻電磁場對高血脂大鼠血清的傅里葉變換紅外光譜和熒光光譜的影響,檢驗采用光譜技術檢測高血脂癥方法的可行性。極低頻電磁場暴露后,高血脂大鼠血脂有一定程度的降低,而且降低高血脂電磁場輻照組血液的相對介電常數(shù)增加導電率,但是本實驗采用的極低頻電磁場對神經(jīng)系統(tǒng)和生殖系統(tǒng)沒有影響。 第三,研究了紅外場暴露的高血脂大鼠部分活性組織(睪丸、肝、血清、腦)的電學特性,并將之與對照組進行了分析比較,探討了紅外場暴露作用對于血液、神經(jīng)和生殖等系統(tǒng)可能存在的一些影響。紅外場暴露后高血脂大鼠血脂降低,降低血液的相對介電常數(shù)增加導電率,而對神經(jīng)系統(tǒng)和生殖系統(tǒng)沒有影響。
[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.
