Researchers suggested that ELF EMF might alter the metabolism of free radicals, decrease antioxidant capability, and enhance lipid peroxidation in mice.

Plain English Summary

Summary written for general audiences

Researchers exposed mice to a 50 Hz sinusoidal electromagnetic field at 0.2 mT or 6.0 mT for 2 weeks, and measured markers of the antioxidant system and cell membrane fluidity in brain and liver tissue. Malondialdehyde content in brain and liver increased with exposure, while total antioxidant capability decreased at both field strengths. When electromagnetic field exposure was combined with lead, the researchers observed synergic effects on lipid peroxidation.

Why This Matters

Cellular membrane fluidity also decreased in both brain and liver at both field strengths tested. The researchers suggested that ELF EMF might alter the metabolism of free radicals.

Study Details

To study the effects of extremely low frequency electromagnetic field(ELF EMF) and its combination with lead on the antioxidant system in mouse brain and liver tissues.

Mice were exposed to a 50 Hz sinusoidal 0.2 mT or 6.0 mT EMF for 2 weeks. At the same time, some gro...

Malondiadehyde(MDA) content in brain and liver increased from the control levels of (1.33 +/- 0.12) ...

ELF EMF might alter the metabolism of free radicals, decrease anti-oxidant capability and enhance lipid peroxidation. The combination of EMF with lead showed synergic effects on lipid peroxidation.
