4 Hz magnetic field decreases oxidative stress in mouse brain: a chemiluminescence study

Abstract

We investigated the effects of delta and theta brain wave frequency magnetic fields (3, 4, and 5) on mouse brain by detecting photonic oxidative stress makers; spontaneous photon emission (SPE) and lucigenin and tert-butyl hydroperoxide (TBHP) induced chemiluminescences (CL). For this purpose, Balb/C mice were exposed to 3, 4, and 5 Hz magnetic fields (MF) at 0.7 mT for 3 h, respectively. After that we monitored SPE and lucigenin and TBHP-induced CL of the homogenates of mice brains. There was a significant decrease in SPE in the 4 Hz MF-exposed group. Lucigenin-induced CL was also significantly decreased only in the 4 Hz MF-exposed group. TBHP-induced CL was also distinctively decreased by all frequencies, 3, 4, and 5 Hz MF exposures. These results showed that oxidative stress in a mouse brain was decreased by 4 Hz MF. We suggest that the application of 4 Hz MF will contribute to magnetic field therapy.
