background: the effects of extremely low frequency electromagnetic fields (elf-emf) on toxoplasma gondii have not been explained yet. the aim of this study was to assess the possible effects of elf-emf on growth, survival time and viability of toxoplasma gondii . in addition, the life span of toxoplasma infected animals was investigated. methods: sixty adult male balb/c mice were used for in vi...
It has been suggested that electromagnetic fields (EMF) act as promoters late in the carcinogenesis process. To date, however, there is no convincing laboratory evidence that EMFs cause tumour promotion at non-thermal exposure levels. Therefore the effects of exposure to electromagnetic fields were investigated in a rat brain glioma model. Some of the exposures correspond to electromagnetic fie...
Since the introduction of Magnetic Resonance Imaging (MRI) as a diagnostic technique, the number of people exposed to electromagnetic fields (EMF) has increased dramatically. In this review, based on the results of a pioneer study showing in vitro and in vivo genotoxic effects of MRI scans, we report an updated survey about the effects of non-ionizing EMF employed in MRI, relevant for patients'...
Mobile phones are two-way radios that emit electromagnetic radiation in microwave range. As the number of mobile phone users has reached 6 billion, the bioeffects of exposure to mobile phone radiation and mobile phone electromagnetic interference with electronic equipment have received more attention, globally. As self-monitoring of blood glucose can be a beneficial part of diabetes control, ho...
The World Health Organization (WHO), through its International EMF Project, has conducted a number of reviews of possible health effects from exposure to fields from various parts of the electromagnetic spectrum. These fields can be grouped into radiofrequencies (RF), intermediate frequencies (IF) and the static and extremely low frequencies (ELF). In addition, there have been substantial revie...
The authors present some data on the effects of electromagnetic fields (EMF) generated by mobile phones on the nervous system. The main attention was paid to the usefulness of some neurophysiological methods, such as electroencephalography (EEG), multimodality evoked potentials (MEP), and event related potentials (ERP) in the evaluation of the bioelectrical activity of the brain. The majority o...
Potential health risk of extremely low frequency electromagnetic field [ELF-EMF] exposure are of considerable public interest. In the present study we investigated the effect of three months exposure to ELF-EMF of frequency [50 Hz] and intensity [50 μT to 500 μT] to which humans can be exposed in their home and work environments on the blood vessels morphology and number in adenohypophysis of m...
OBJECTIVE We sought direct evidence that acute exposure to environmental-strength electromagnetic fields (EMFs) could induce somatic reactions (EMF hypersensitivity). METHODS The subject, a female physician self-diagnosed with EMF hypersensitivity, was exposed to an average (over the head) 60-Hz electric field of 300 V/m (comparable with typical environmental-strength EMFs) during controlled ...
BACKGROUND Indisputable population exposure to widespread electromagnetic fields, has grown concerns over the probable health effects of these fields. OBJECTIVE The present study was aimed to examine the possible effects of 50 Hz extremely low frequency electromagnetic field (ELF-EMF) exposure on the number and quality of mice blastocysts. MATERIALS AND METHODS In present study, 66 NMRI pre...
Electromagnetic waves (EMF) are a mixture of electrical and magnetic waves. The energy transmitted by these radiations is absorbed by living tissues. Electromagnetic fields seem to cause infertility in women. Cannabis is annual herbaceous plant grows in tropical areas. This study was conducted to investigate the protective effects of hydroalcoholic extract of Cannabis sativa in various doses of...
