研究目的(著者による)

To study the stress response in the mouse brain after repeated, polonged (2 years) exposure using c-fos.

詳細情報

Archival mouse brains from a previous study on tumour (lymphoma) development were used (see publication 9121). The authors also used these brains for another study on blood-brain barrier permeability (see publication 9247).

ばく露装置
ばく露の発生源/構造
ばく露装置の詳細 The Ferris-wheel exposure system consisted of a cylindrical parallel plate with mice restrained in clear Perspex tubes arranged radially around a dipole antenna. 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 freely moving cage control group was also included.
