P-105: Prenatal Effects Exposure to Extremely Low Frequency- Electromagnetic Field (ELF-EMF) on Pathology of Testis in Newborn Rats
Authors
Abstract:
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 affect the reproductive system. The aim of this work is to evaluate the effects of intrauterine exposure to 50Hz electromagnetic field (ELF-EMF) on testicular development. Materials and Methods: Pregnant wistar rats were exposed to 3mT, EMF for 21 days (4 hours/day). Pregnant rats under the same condition of treatment group, but off the field as a Sham group intended and pregnant rats were used as control in the room. After delivery, testis were removed from male pups, fixed and prepared for light microscopic studies. Results: Microscopic results revealed seminiferous tubules in treatment group were widely separated from each other, in this group in seminiferous tubules vacuolization, detachment of gonocytes from each other, heterochromatic gonocytes and decreasing in interstitial tissue in comparison with the control and sham groups was found. In sham and control groups the seminiferous tubules and interstitial tissue appeared normal. Conclusion: Early pregnancy exposure to magnetic field affects gonads in prenatal male fetuses and postnatal testicular development. EMF can influence the mechanism of apoptosis and also lead to increased apoptosis rate of germ cells. In general, as a result of the exposure to EMF during early developmental period, morphological changes in testicular development were evident that may well extend till adult stage and may affect fertility.

P-198: Study Effects of EMF on Pathology of Ovary in Newborn Rats during Developmental Period
Background: The effect of electromagnetic field (EMF) as an environmental factor on different organs including female reproductive system is of critical concern. In view of the fact that embryo fetuses and young, growing animals are more susceptible to any xenobiotic during gestational and lactation stages of gonadal development may it lead to permanent damage to the gonads. The early phases of...

The present cytogenetic study was conducted on subjects occupationally exposed to extremely low frequency electromagnetic fields (ELF–EMF), whereby Chromosomal Aberrations (CAs) and Sister Chromatid Exchange (SCE) frequencies were premeditated. These subjects were electric substation attendants, electric arc welders and individuals working in the vicinity of electric distribution point (DP) tra...

In the past three decades, study on the biological effects of extremely low-frequency electromagnetic fields (ELF-EMFs) has been of interest to scientists. Although the exact mechanism of its effect is not fully understood, free radical processes has been proposed as a possible mechanism. This study was designed to evaluate the effect of 50-Hz EMFs on the mRNA levels of seven antioxidant genes ...

Introduction: The present study investigated the interactive effect of GABAB receptors and extremely low frequency electromagnetic field (ELF-EMF) on foot shock-induced aggression in rats. Methods: fifty adult male rats were randomly assigned into 10 groups. Groups 2, 4, 6, 8 and 10 were exposed to 50 Hz, 500 µT ELF-EMF for 30 days 8h per day while the remaining groups (1, 3, 5, 7 and 9) were...
