The aim of this
study was to investigate whether 900 MHz radiation could affect astroglial
and microglial cells in culture. The authors exposed the cells in special
temperature-controlled cultures at SARs of 3 W/kg GSM modulated wave
for 4, 8, and 24 hours, or 27 W/kg continuous wave for 24 hours. They
assessed astroglial cell damage by measuring the amount of release into
the extracellular medium of two pro-inflammatory cytokines - Il6 and
Tfna, and the reactive marker Gfap. There were no differences in the
levels seen when compared with control cell cultures. Microglial cells
also showed no differences in levels of Il6, Tfna, or the microglial
reactivity marker ED-1. The morphology of the cells also showed no evidence
of damage. On the other hand, positive controls that were exposed to
increased temperature (sometimes as little as 1ºC rise) did show
evidence of cell damage.
The authors concluded
that there was no evidence in their study that RFR had any effect on
glial cells in culture.
