Background and Objective: Nitric Oxide in the small intestine causes relaxation of smooth muscles. Research indicates that extremely low frequency electromagnetic fields (ELF) affect nitric oxide level in the tissues. The objective of this study was to grasp the effect of prolonged exposure to ELF on the nitrergic system in the small intestine. Materials and Methods: 21 adult male rats were ...

Nitric oxide (NO) is one of the most important signal molecules, involved in both physiological and pathological processes. As a neurotransmitter in the central nervous system, NO regulates cerebral blood flow, neurogenesis, and synaptic plasticity. The aim of our study was to investigate the effect of the extremely low-frequency electromagnetic field (ELF-EMF) on generation and metabolism of N...

This study investigated the effects of electromagnetic fields on enzymes involved in purine metabolism in human peripheral blood mononuclear cells in vitro. Cells were obtained from 20 volunteers. We tested both low-energy, extremely low frequency (ELF; 100-Hz) electromagnetic fields and the Therapeutic Application of Musically Modulated Electromagnetic Fields (TAMMEFs); the latter is character...

Background: Extremely low frequency (0-300 Hz) fields from power lines, electronic equipment and medical devices, have been reported to produce various biological effects. Global system for mobile (GSM) is most largely used in everybody's life. This system utilizes a low frequency band as well as a high frequency range of electromagnetic field. This study investigated the effects of 217 Hz elec...

Background: Human beings are unavoidably exposed to ambient electromagnetic fields (EMF) generated from various electrical devices and from power transmission lines. The effects of extremely low-frequency electromagnetic fields (ELF-EMF) on the biological functions of living organisms represent an emerging area of interest for human health. One of the critical issues is that EMF may adversely a...
