Effects of whole body exposure to extremely low frequency electromagnetic fields (ELF-EMF) on serum and liver lipid levels, in the rat

Abstract

Backgound: The effects of extremely low-frequency electromagnetic fields (ELF-EMF) on the blood serum and liver lipid concentrations of male Wistar rats were assessed.Methods: Animals were exposed to a single stimulation (2 h) of ELF-EMF (60 Hz, 2.4 mT) or shamstimulated and thereafter sacrificed at different times (24, 48 or 96 h after beginning the exposure).Results: Blood 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. Conclusion:Single 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.

Effect of Magnetic Water Treatment and Some Additives on Growth Performance, Some Blood Biochemical Parameters and Intestinal Health of Growing Pekin Ducklings

“…A therapeutic effect of EMF on obesity and complicated hyperlipidemia was documented by (Zhang and Sheng, 2005 values of HDL-c and decreased total cholesterol concentration of rat liver (Torres-Duran et al, 2007). On the other hand, a beneficial effect of EMF was also reported in diet induced hypercholesterolemic rabbit, where pulse of EMF lowered total cholesterol and triglyceride level (Luo et al, 2004).…”

Effects of electromagnetic fields on serum lipids in workers of a power plant

“…Nevertheless, another human study reported that compared with radio relay station operators, significantly higher serum TC and LDL-c were found both in broadcasting station and TV station operators, with no change of serum TG and HDL-c (Vangelova et al 2006). In addition, many animal studies also reported that exposure to EMF could influence plasma or serum TC and TG, with few studies concerning serum LDL-c and HDL-c, but the results were inconsistent across studies (Bellossi et al 1998;Celikozlu et al 2012;Güler et al 2007;Hori et al 2012;Lahbib et al 2010;Lee et al 2006;Luo et al 2007;Portet and Cabanes 1988;Torres-Duran et al 2007).…”

Impact of Biofield Energy Treated (The Trivedi Effect<sup>®</sup>) Herbomineral Formulation on the Immune Biomarkers and Blood Related Parameters of Female <i>Sprague Dawley</i> Rats

“…Biofield Energy Treatment includes the use of a low intensity electromagnetic field (the Biofield) by the Energy Healers, so the altered lipid profile activity might be due to the Biofield Energy transferred to the test formulation. A scientific study showed a beneficial effect of an extremely low frequency electromagnetic field on animal lipid profile by altering lipid metabolism [49]. Thus, it might be suggested, that the Biofield Energy Healing Treatment on the test formulation alters the lipid metabolism of animals, which would be useful against various inflammatory disease conditions.…”
