Medical/biological Study (experimental study)Effects of whole body exposure to extremely low frequency electromagnetic fields (ELF-EMF) on serum and liver lipid levels, in the rat. med./biol. By: Torres-Duran PV, Ferreira-Hermosillo A, Juarez-Oropeza MA, Elias-Vinas D, Verdugo-Diaz L
Published in: Lipids Health Dis 2007; 6 : 31 (  PubMed Entry , Journal web site )Aim of study (according to author)
To study the effects of extremely low frequency electromagnetic fields on the blood serum and liver lipid concentrations of male rats.
Background/further details:
Rats (n=40, 5 rats per group) were exposed to electromagnetic fields or sham exposed and thereafter sacrificed at different times (24, 48 or 96 h after beginning of the exposure). Endpoint Exposure
General category: magnetic field, 50/60 Hz (AC)
FIELD View further expo parametersExposed system:
animal (species/strain): rat/Wistar Methods
Endpoint/Measurement parameters/Methodology investigated material: isolated bio./chem. substance (in vitro), blood/serum; liver homogenates
organ system(s): liver
time of investigation: after exposure
Main outcome of study (according to author)
Exposure to extremely low frequency electromagnetic fields increased the serum values of HDL-cholesterol (in the 48 h group), the liver content of lipoperoxides (in the 24 h group) and decreased total cholesterol of the liver (significant in the 96 h group). The mechanisms for the effects of extremely low frequency electromagnetic fields on lipid metabolism are not well understood yet. (Study character: medical/biological study, experimental study, full/main study)
