The Impact of Electromagnetic Radiation of Different Parameters on Platelet Oxygen Metabolism – In Vitro Studies

Abstract

Background. Electromagnetic radiation emitted by a variety of devices, e.g. cell phones, computers and microwaves, interacts with the human body in many ways. Research studies carried out in the last few decades have not yet resolved the issue of the effect of this factor on the human body and many questions are left without an unequivocal answer. Various biological and health-related effects have not been fully recognized. Thus further studies in this area are justified. Objectives. A comparison of changes within catalase enzymatic activity and malondialdehyde concentration arising under the influence of the electromagnetic radiation emitted by car electronics, equipment used in physiotherapy and LCD monitors. Material and Methods. The suspension of human blood platelets at a concentration of 1 × 10 9 /0.001 dm

Impact of electromagnetic radiation emitted by monitors on changes in the cellular membrane structure and protective antioxidant effect of vitamin A – In vitro study

“…Another study has demonstrated that the low frequency electromagnetic fields generated by car electronics, physiotherapy equipment and LCD monitors may be the cause of oxidative stress in the human body. During this experiment an increase in catalase activity and MDA concentration is observed after 30 min exposure of platelets to EMF regardless of the radiation source [21]. The obtained results are similar to the ones as the outcome of this study excluding the observation time (our study has indicated increase in MDA concentration after 60 min exposure and insignificant increase after 30 min exposure).…”

Extremely Low-Frequency Magnetic Field as a Stress Factor—Really Detrimental?—Insight into Literature from the Last Decade

“…Ehnert et al [80] found ELF-MF-induced (16 Hz 6-282 µT) increase of SOD2, CAT, GPX3, and glutathione-disulfide reductase (GSR) activity concomitant with the reduction of ROS levels in human osteoblasts. Similarly, in the myelogenous leukemia cell line K562 exposed to ELF-MF (50 Hz, 1 mT) and in human blood platelets exposed to different sources of electromagnetic radiation (1 kHz, 0.5 mT; 50 Hz, 10 mT; or 1 kHz 220 V/m) CAT activity was increased [81,82]. Moreover, the exposure IMR-90 human lung fibroblasts for a total of 168 h to 6 mT ELF-MF contributed to decreased ROS level [83].…”

The antioxidant effects of melatonin in blood platelets during exposure to electromagnetic radiation – an in vitro study

“…Oxidative stress can be caused by various environmental factors, including chemical and physical pollution, behavior factors, such as cigarette smoke and alcohol, as well as certain nutrients, such as saturated fat. In addition, a number of reports have examined the effects of electromagnetic radiation (EMR) exposure on the oxidative metabolism of cells [1,2]; these range from increased lipid peroxidation caused by ROS to changes in the activity of antioxidant enzymes in various cells and tissues [3].…”
