Effects of 900-MHz electromagnetic field emitted from cellular phone on brain oxidative stress


Guinea pigs produce cortisol as opposed to corticortoids in rats and mice -- i.e., "biologically closer to humans".

 

Attached, a study showing oxidative stress on guinea pigs, after short exposition to 900 MHz.

This study was designed to demonstrate the effects of 900MHz electromagnetic field (EMF) emitted from cellular phone on brain tissue and also blood malondialdehyde (MDA), glutathione (GSH), retinol (vitamin A), vitamin D(3) and tocopherol (vitamin E) levels, and catalase (CAT) enzyme activity of guinea pigs. Fourteen male guinea pigs, weighing 500800 g were randomly divided into one of two experimental groups: control and treatment (EMFexposed), each containing seven animals. Animals in treatment group were exposed to 890to 915MHz EMF (217Hz pulse rate, 2W maximum peak power, SAR 0.95 w/kg) of a cellular phone for 12 h/day (11h 45min standby and 15min spiking mode) for 30 days. Control guinea pigs were housed in a separate room without exposing EMF of a cellular phone. Blood samples were collected through a cardiac puncture and brains were removed after decapitation for the biochemical analysis at the end of the 30 days of experimental period.
