この研究では、0.9及び1.8GHzの連続波(CW)無線周波放射への20分間のばく露(SARはそれぞれ4.26mW/kg及び1.46mW/kg)が、雌雄のWistarアルビノラットの血液脳関門(BBB)の透過性に及ぼす影響を調べた。その結果、ばく露群の雄ラットの脳で偽ばく露群の雄の脳と比較してアルブミンの有意な増加が認められたことを報告している。

To study the effect of radiofrequency exposure on the permeability of the blood-brain barrier in male and female rats.
The right hemisphere, left hemisphere, cerebellum, and total brain were analyzed separately.
The animals were divided into six groups (n=9 per proup): 1) sham exposed female rats, 2) sham exposed male rats, 3) 0.9 GHz exposed females 4) 0.9 GHz exposed males, 5) 1.8 GHz exposed females, 6) 1.8 GHz exposed males.

The animals were treated in the following six groups: i) female sham exposure ii) male sham exposure iii) female exposure to 0.9 GHz iv) male exposure to 0.9 GHz v) female exposure to 1.8 GHz vi) male exposure to 1.8 GHz

No albumin extravasation was found in the brains of female rats after radiofrequency exposure. However, a significant increase in albumin extravasation was found in the brains of the exposed male rats when compared to sham exposed male animals.
These data suggest that 0.9 and 1.8 GHz radiofrequency exposure (continuous wave) at levels below the international limits can affect the vascular permeability in the brain of male rats.
