The effects of electromagnetic waves (EMWs) on humans and their relationship with various disorders have been investigated. We aimed to investigate the effects of exposure to different frequencies of EMWs in various durations in a mouse epilepsy model induced by pentylenetetrazole (PTZ).
A total of 180 4-week-old male mice weighing 25-30 g were used in this study. Each experimental group consisted of 10 mice. They were exposed to 900, 700, 500, 300, and 100 MHz EMWs for 20 hours, 12 hours and 2 hours. Following electromagnetic radiation exposure, 60 mg/kg of PTZ was injected intraperitoneally to all mice. Each control was also injected with PTZ without any exposure to EMW. The latency of initial seizure and most severe seizure onset were compared with controls.
The shortest initial seizure latency was noted in the 12-hour group, followed by the 700 MHz. The mean initial seizure latencies in the 2-hour EMW exposed group was significantly shorter compared to that in the 12- and 20-hour groups. There was no significant difference between 12- and 20-hour EMW exposed groups. There was a significant difference between control and 2- and 10-hour EMW exposed groups. No statistically significant differences were noted in mean latencies of the most severe seizure latency, following 20-, 12-, and 2- hour EMW exposed groups and control groups.
Our findings suggest that acute exposure to EMW may facilitate epileptic seizures, which may be independent of EMW exposure time. This information might be important for patients with epilepsy. Further studies are needed.
已对电磁波(EMW)对人类的影响及其与各种疾病的关系进行了研究。我们旨在研究在戊四氮(PTZ)诱导的小鼠癫痫模型中,不同频率的EMW在不同持续时间的暴露影响。
本研究共使用180只4周龄、体重25 - 30克的雄性小鼠。每个实验组由10只小鼠组成。它们分别暴露于900、700、500、300和100 MHz的EMW下20小时、12小时和2小时。电磁辐射暴露后,对所有小鼠腹腔注射60 mg/kg的PTZ。每个对照组也注射PTZ,但未暴露于任何EMW。将初始癫痫发作和最严重癫痫发作开始的潜伏期与对照组进行比较。
12小时组的初始癫痫发作潜伏期最短,其次是700 MHz组。与12小时和20小时组相比,暴露于EMW 2小时组的平均初始癫痫发作潜伏期明显更短。12小时和20小时EMW暴露组之间没有显著差异。对照组与2小时和10小时EMW暴露组之间存在显著差异。在暴露于EMW 20小时、12小时和2小时的组以及对照组之后,最严重癫痫发作潜伏期的平均潜伏期没有统计学上的显著差异。
我们的研究结果表明,急性暴露于EMW可能会促进癫痫发作,这可能与EMW暴露时间无关。这一信息对癫痫患者可能很重要。需要进一步研究。
