Finnie and colleagues previously examined vascular permeability changes in the fetal mouse brain after exposure to RFR. In the present paper they reported blood-brain barrier integrity in the neonatal brain after exposure to mobile telephony.
The authors exposed
newborn mice to a 60-minute far-field whole body exposure of 4 W/kg on
7 successive days postnatally. The RF field had similar characteristics
to the GSM field. Four groups of animals were used: exposed, sham-exposed;
a non-exposed, freely-moving, cage control group; and a positive control
group injected with cadmium chloride, which produces microvascular endothelial
damage. There were 10 animals in each group. The mice were sacrificed
at day 7, and the brains were examined for evidence of disruption of the
BBB. Albumin was used as the marker for this. No evidence of BBB breakdown
was found in the exposed or control groups. Albumin leakage into neurons
was found in the mice injected with cadmium.
