摘要
近年来,人们在电磁场产生的生物学效应及应用的研究越来越广泛,这其中包括对连续电磁波的生物热效应和非热生物效应,以及对瞬态电磁场与生物体的相互作用影响等方面。
     电穿孔效应是指在适当高压脉冲电场作用下,细胞或组织间起相对隔离作用的“屏障”内快速形成液态通道的现象,是电场与具有不同介电常数而且易变形的物质相互作用的结果。本文从孔的形成、阈值跨膜电压、膜损伤、分子运输、组织穿孔、膜恢复和细胞死亡等方面论述了电穿孔效应的产生机理,并对电穿孔效应的应用进行了总结,在此基础上,结合电穿孔生物效应实验研究和应用特点,设计制作了一台智能化电穿孔仪,该仪器具有矩形脉冲和电容放电脉冲两种波形输出,并且脉冲幅值、脉冲宽度、重复频率可调,文中对它的工作原理、系统结构、性能参数作了简要说明。
     毫米波(MMW)生物效应也是人们研究的一个重要方面。本文在介绍了几种典型的毫米波生物效应,并对其应用以及目前在毫米波生物效应机理研究方面的各种理论模型作了概括后,对毫米波作用人舌癌细胞产生的效应进行了较系统的研究,主要集中在细胞对毫米波吸收的频率和强度的选择性问题上,最后对实验结果进行了分析讨论。
In recent years, the biological and medical effects of electromagnetic field has been studied widely including the thermal and non-thermal effects of continuous electromagnetic wave and the effects of transient electromagnetic field.
    The essentially universal biophysical phenomenon of "electroporation" occurs if an appropriate pulse field is applied. Electroporation is believed to be the rapid creation of aqueous pathways through lipid-containing barriers in cells and tissue. The driving force is the physical interaction of electric fields with different dielectric constants. This thesis introduced the phenomenon of electroporation and gave some discussions on the mechanism of electroporation in various aspects such as pore formation, membrane damage, tissue electroporation, membrane recovery and cell death and so on. This thesis designed a intellectualized electroporation instrument which can output rectangular pulse and capacitor discharge pulse. The voltage output, pulsewidth and repetition can be variable. The principle, hardware and software system and specifications were introduced in this paper.
    The research of biological medical effects of millimeter wave (MMW) has been of compelling interest. This thesis reviewed the new effects of MMW and some representative opinions about the mechanism of MMW effects. The inducing effect of MMW on tongue cancer cell has been researched in this paper. According to the research result, this thesis gave a discussion on the problem of frequency and power of MMW.
