Effect of Pulsed Electromagnetic Field Exposure on Glutathione Amount in Human Neuroblastoma Cell Line Treated with High-Dose Hydrogen Peroxide

The Pulsed Electromagnetic Field (PEMF) is one of the non-ionizing forms of electromagnetic fields that has been used as an alternative therapy for various medical problems, including treating symptoms of neurodegenerative disorders. The present work’s goal is to explore the possible effects of short-term exposure to 75 Hz frequency of PEMF on the amount of glutathione (GSH) in high-dose hydrogen peroxide (H2O2) treated human neuroblastoma cell line. Cells were divided into three experimental groups: (I) sham-control; (II) cells treated by H2O2; (III) cells post-exposed to PEMF following H2O2 challenge. The cell viability and the amount of glutathione were measured by spectrophotometrically and High Performance Liquid Chromatography (HPLC) techniques, respectivelly. It has been found that the cytoprotective effect of post-PEMF exposure against deleterious effects of oxidative stress triggered by high-dose H2O2 challenge in neuroblastoma cell line is mediated by the increase in the cell viability and the elevation in the GSH amount.
