Model		900 MHz (GSM) exposure to guinea pigs and analysis of oxidative stress in brain tissue
Details		Guinea pigs (n = 7) were exposed to 900 MHz (GSM) for 12 hours/day (11.75 hrs in standby, 15 minutes connected in a call), 30 days, at a reported SAR of 0.95 W/kg. The authors report that in brain tissue, RF exposure resulted in elevated MDA levels and lower GSH and CAT enzyme levels in brain tissue, with no effect on vitamin A, D3, or E were observed due to RF exposure. In blood tissue, RF exposure resulted in increased MDA, decreased GSH, and increases CAT, vitamins A, D3, and E. The authors suggest RF exposure could result in an increased free radical production and lipid peroxidation in brain and blood tissue.

Comments		Exposure did not seem to be measured, but taken as max value (using a 2 watt output) from previously measured values for compliance. No description of the expsoure system was provided, probably a phone hooked up to the network. Further, the 15 minute actual exposure was not apparently done with voice, so DTx was probably active.
