The interaction of static magnetic fields (SMFs) with living organisms is a rapidly growing field of investigation. The magnetic fields (MFs) effect observed with radical pair recombination is one of the well-known mechanisms by which MFs interact with biological systems. SMF influenced cellular antioxidant defense mechanisms by affecting antioxidant enzymes such as superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT). However, there were insufficient reports about the effects of SMF on macro and trace elements in serum, and the results were contradictory until now. In the current study, 12 rats were divided into two groups, namely as control and exposure group (128 mT and 1 h/day during five consecutive days). The macro and trace element concentrations in serum were examined. No significant difference was observed in the sodium (Na), potassium (K), calcium (Ca), phosphorus (P), and selenium (Se) levels in rat compared to control. By contrast, exposure to SMF showed an increase in the zinc (Zn) level and a decrease in iron (Fe) concentration. Under our experimental conditions, SMF exposure cannot affect the plasma levels of macroelements, while it can disrupt Zn and Fe concentrations in rat.
静磁场(SMFs)与生物体的相互作用是一个快速发展的研究领域。通过自由基对重组观察到的磁场(MFs)效应是MFs与生物系统相互作用的著名机制之一。静磁场通过影响超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GPx)和过氧化氢酶(CAT)等抗氧化酶来影响细胞抗氧化防御机制。然而,关于静磁场对血清中常量和微量元素影响的报道并不充分,迄今为止结果相互矛盾。在本研究中,将12只大鼠分为两组,即对照组和暴露组(128 mT,连续5天每天1小时)。检测了血清中常量和微量元素的浓度。与对照组相比,大鼠血清中的钠(Na)、钾(K)、钙(Ca)、磷(P)和硒(Se)水平未观察到显著差异。相比之下,暴露于静磁场会使锌(Zn)水平升高,铁(Fe)浓度降低。在我们的实验条件下,静磁场暴露不会影响大鼠血浆中常量元素的水平,但会扰乱大鼠体内锌和铁的浓度。
