研究目的(著者による)

To study the effect of mobile telephone exposure on blood-brain barrier permeability in the immature brain of mice.

詳細情報

Pregnant mice were exposed from day 1 to day 19 of gestation and immediately prior to parturition on gestational day 19, fetal heads were collected. A positive control group with cadmium-induced blood-brain barrier damage was also included.

ばく露装置
ばく露の発生源/構造
ばく露装置の詳細 The exposure system consisted of a cylindrical parallel plate with mice restrained in clear Perspex tubes, preventing them from changing their orientation, and arranged radially around the dipole antenna. A forced air supply was maintained through the cylinders to ensure no heat build-up, and there was no rise in core body temperature.
Additional information Pregnant control mice were sham-exposed or freely moving in a cage. A positive control group obtained cadmium-induced BBB damage.
