Abstract

The aim of the present work is to evaluate possibility of microwave emitted by cellular phone that can elicit cortical spreading depression (CSD) in rat brain and studying the characteristics of the evoked signals. (CSD) was elicited in cerebral cortex of anesthetized rats after exposure to microwave irradiation (935.2-960.2 MHz) from Global System for Mobile communications (GSM) mobile phone. With the microwave output of about 8.5 mW at the antenna - tissue surface (4mm in diameter), CSD was elicited after 50 sec irradiation from the beginning of a received signal to the mobile and after 35 sec irradiation from the beginning of a transmitted signal from the mobile. CSD was elicited in about 90% of experiments after irradiation by both types of signal exposure. The results have shown that slow potential change (SPC) has an amplitude of 4.5 ± 0.75 mV, duration of 1.5 ± 0.5 min and propagated speed of 3 mm/min on the average. The amplitude, duration and behaviour of SPC of the evoked spreading depression were found to be affected by irradiation time and the method of exposure.

摘要

本研究的目的是评估手机发出的微波是否有可能在大鼠脑中引发皮层扩散性抑制（CSD），并研究诱发信号的特征。在暴露于全球移动通信系统（GSM）手机发出的微波辐射（935.2 - 960.2 MHz）后，在麻醉大鼠的大脑皮层诱发了CSD。天线 - 组织表面（直径4mm）的微波输出约为8.5 mW，从接收到手机信号开始照射50秒后以及从手机发射信号开始照射35秒后诱发了CSD。在两种类型的信号暴露照射后，约90%的实验诱发了CSD。结果表明，慢电位变化（SPC）的平均幅度为4.5±0.75 mV，持续时间为1.5±0.5分钟，传播速度为3 mm/分钟。发现诱发的扩散性抑制的SPC的幅度、持续时间和表现受照射时间和暴露方法的影响。
