Abstract

BackgoundThe effects of extremely low-frequency electromagnetic fields ELF-EMF on the blood serum and liver lipid concentrations of male Wistar rats were assessed.

MethodsAnimals were exposed to a single stimulation 2 h of ELF-EMF 60 Hz, 2.4 mT or sham-stimulated and thereafter sacrificed at different times 24, 48 or 96 h after beginning the exposure.

ResultsBlood lipids showed, at 48 h stimulated animals, a significant increase of cholesterol associated to high density lipoproteins HDL-C than those observed at any other studied time. Free fatty acid serum presented at 24 h significant increases in comparison with control group. The other serum lipids, triacylglycerols and total cholesterol did not show differences between groups, at any time evaluated. No statistical differences were shown on total lipids of the liver but total cholesterol was elevated at 24 h with a significant decrease at 96 h p = 0.026. The ELF-EMF stimulation increased the liver content of lipoperoxides at 24 h.

ConclusionSingle exposures to ELF-EMF increases the serum values of HDL-C, the liver content of lipoperoxides and decreases total cholesterol of the liver. The mechanisms for the effects of ELF-EMF on lipid metabolism are not well understand yet, but could be associated to the nitric oxide synthase EMF-stimulation.
