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

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.
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).
General category: magnetic field, 50/60 Hz (AC)
FIELD View further expo parameters
animal (species/strain): rat/Wistar
Methodsinvestigated 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.
