この研究は、Wister雄ラット(n=10)に低レベルの電磁界(100kHzでFM変調した900MHz;15.14V/m)の45分間の1回ばく露を与え、血液セロトニン(5-HT)およびグルタミン酸レベルを測定した。その結果、ばく露により5-HTは有意に上昇し、グルタミン酸レベルは変化しなかった、と報告している。

研究目的(著者による)

The effects of exposure of rats to a 900 MHz electromagnetic field on the blood level of serotonin and glutamate should be investigated.

詳細情報

Serotonin and glutamate were investigated as crucial factors for the function of the brain.
9 anesthetized rats were exposed to the electromagnetic field. Shortly before (control values) and after the exposure, a blood sample was taken from each rat.

研究の主なアウトカム(著者による)

The serotonin level was significantly increased after exposure compared to the measurement before, whereas the glutamate level was not changed significantly.
The authors conclude that exposure of rats to a 900 MHz electromagnetic field could have an effect on the serotonin blood level.
