研究目的(著者による)

To study immediate early gene expression (c-fos) as a marker of neural stress after whole of gestation exposure of the fetal mouse brain to mobile phone-type radiofrequency fields.

詳細情報

10 pregnant mice were exposed and one fetal brain was selected from each pregnant female. Immediately prior to parturition on gestational day 19, fetal heads were collected.

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 arranged radially around the antenna [Balzano et al., 2000; Faraone et al., 2006]. A forced air supply was maintained through the cylinders to prevent heat build-up, and there was no rise in core body temperature.
Sham exposure A sham exposure was conducted.
Additional information A non-exposed, freely moving, cage control group without handling was also included.
