Study type: 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./bio.

Published in: Lipids Health Dis 2007; 6: 31

Aim of study (acc. 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).

Main outcome of study (acc. 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.
