The present study determined whether 4 weeks of moderate aerobic exercise improves antioxidant capacity on the brain of rats against oxidative stress caused by radiofrequency electromagnetic radiation emitted from cell phones.
Responses of malondialdehyde, catalase, glutathione peroxidase, and superoxide dismutase, as well as the number of hippocampal dead cells, were examined. Male Wistar rats (10-12 wk old) were randomly assigned to 1 of 4 groups (N = 8): (1) moderate aerobic exercise (EXE) (2 × 15-30 min at 1215 m/min speed with 5 min of active recovery between sets), (2) exposure to 900/1800 MHz radiofrequency electromagnetic waves 3 hours per day (RAD), (3) EXE + RAD, and (4) exposure to an experimental phone without battery.
Following the exposure, the number of the hippocampal dead cells was significantly higher in group RAD compared with groups EXE, EXE + RAD, and control group. Malondialdehyde concentration in group RAD was significantly higher than that of groups EXE, EXE + RAD, and control group. Also, the activity of catalase, glutathione peroxidase, and superoxide dismutase in groups EXE, EXE + RAD, and control group was significantly higher compared with those of the exposure group.
This study demonstrated that moderate aerobic exercise enhances hippocampal antioxidant capacity against oxidative challenge in the form of radiofrequency electromagnetic waves.
本研究旨在确定为期4周的适度有氧运动是否能提高大鼠大脑的抗氧化能力，以抵御手机发出的射频电磁辐射所引起的氧化应激。
检测丙二醛、过氧化氢酶、谷胱甘肽过氧化物酶和超氧化物歧化酶的反应，以及海马体死亡细胞的数量。将雄性Wistar大鼠（10 - 12周龄）随机分为4组中的1组（每组n = 8）：（1）适度有氧运动组（EXE）（以1215米/分钟的速度进行2×15 - 30分钟运动，每组间有5分钟的主动恢复时间），（2）每天暴露于900/1800 MHz射频电磁波3小时组（RAD），（3）EXE + RAD组，（4）暴露于无电池的实验手机组。
暴露后，RAD组海马体死亡细胞数量显著高于EXE组、EXE + RAD组和对照组。RAD组丙二醛浓度显著高于EXE组、EXE + RAD组和对照组。此外，EXE组、EXE + RAD组和对照组中过氧化氢酶、谷胱甘肽过氧化物酶和超氧化物歧化酶的活性显著高于暴露组。
本研究表明，适度有氧运动可增强海马体的抗氧化能力，以抵御射频电磁波形式的氧化挑战。
