Effects of extremely low frequency electromagnetic fields on testes in guinea pig.

Research RF Safe Research Library Jan 1, 2007

This animal study exposed 36 adult male guinea pigs to extremely low frequency electromagnetic fields at 5 Hz or 50 Hz and compared testosterone and testes tissue outcomes with sham/control conditions. After 5 days, the authors report a significant decrease in testosterone in exposed groups versus controls. They also…

Ultrastructural alterations and occurrence of apoptosis in developing follicles exposed to low frequency electromagnetic field in rat ovary.

Research RF Safe Research Library Jan 1, 2007

This animal study examined rat ovaries after chronic exposure to a 3 mT low-frequency electromagnetic field for 4 hours per day over 4 months. Using TEM and TUNEL, the authors report ultrastructural alterations in oocytes and more frequent apoptosis-associated changes in granulosa and corona radiata cells versus…

Effects of electromagnetic field produced by mobile phones on the oxidant and antioxidant status of rats.

Research RF Safe Research Library Jan 1, 2007

This rat study examined whether EMR from GSM mobile phones affects oxidant/antioxidant status. Compared with controls, exposed rats had lower plasma antioxidant vitamins (C, E, A), reduced glutathione, and lower CAT and SOD activities. The acute exposure condition was reported to produce larger decreases than the…

Exposure to an additional alternating magnetic field affects comb building by worker hornets.

Research RF Safe Research Library Jan 1, 2007

This animal study reports that exposing worker oriental hornets in an artificial breeding box to an additional 50 Hz magnetic field (50–70 mGauss) altered comb construction compared with controls under only the terrestrial magnetic field. The abstract describes fewer cells and eggs, more deformed cell geometry, and…

900 MHz radiofrequency-induced histopathologic changes and oxidative stress in rat endometrium: protection by vitamins E and C.

Research RF Safe Research Library Jan 1, 2007

This rat study examined 900 MHz radiofrequency exposure (30 min/day for 30 days) and reported biochemical and histopathologic changes in endometrial tissue consistent with oxidative stress and tissue injury. The abstract reports increased NO and MDA and decreased antioxidant enzyme activities (SOD, CAT, GSH-Px) in…

Evaluation of mulitprobe radiofrequency technology in a porcine model.

Research RF Safe Research Library Jan 1, 2007

This animal study evaluated two multiprobe radiofrequency ablation device approaches in pigs, including an impedance-based algorithm and clustered/combination probes with and without a switcher controller. The Pringle maneuver was associated with larger ablation volumes and shorter ablation times in one experiment,…

Effects of pulsed electromagnetic field vibration on tooth movement induced by magnetic and mechanical forces: a preliminary study.

Research RF Safe Research Library Jan 1, 2007

This randomized animal study tested whether pulsed electromagnetic field (PEMF)-induced vibration affects orthodontic tooth movement produced by magnetic and/or mechanical forces. Forty-four Wistar rats were exposed to PEMF-induced vibration or normal atmosphere while tooth movement was induced using magnets and/or…

The effect of pulsed and sinusoidal magnetic fields on the morphology of developing chick embryos

Research RF Safe Research Library Jan 1, 1997

This animal study reports results from five experimental campaigns over five years examining weak magnetic field exposure and morphological abnormalities in White Leghorn chick embryos. Four campaigns reported statistically significant increases in abnormality rates, while one pulsed-field campaign showed only a…

Biological effects of extremely low frequency electric and magnetic fields: a review

Research RF Safe Research Library Jan 1, 1977

This review summarizes reported biological effects of extremely low frequency (ELF) electric and magnetic fields, describing them as significant and often acting as stressors. Reported outcomes include metabolic, hormonal, and body weight changes in rodents, lethality at high exposure levels in mice and insects, and…

Evaluation of Electrochemical Information Transfer System: I . Effect of Electric Fields on Living Organisms

Research RF Safe Research Library Jan 1, 1976

This 1976 animal study evaluated the effects of weak ELF electric fields similar to those associated with Project Seafarer on mice. The abstract reports that electric field exposure acted as a biological stressor, with effects involving the central nervous and endocrine systems. It is presented as part of broader…
