この実験研究は、ほうれん草の葉の細胞から作成した、高度に純化した原形質膜小胞におけるCa2＋輸送に対する60H磁界の影響を調べ、Lednevが提案した量子メカニズムモデル（水素原子の核分極効果）を検証した。45Ca2＋をトレーサとして、26 μTの静磁界および0.6－6.3 μTの60Hzのばく露を受けた小胞におけるカルシウムイオン流出の動態を測定した結果、Lednevのモデルで予測されるような現象は確認されなかったと報告している。

To study the effects of extremely weak 60 Hz magnetic fields on the transport of Ca2+ in a biological system consisting of highly purified plasma membrane vesicles.
The authors tested a proposed quantum mechanical model postulating that magnetic field induced polarization of hydrogen nuclei can elicit a biological effect (see Belova et al. 2007).
|ばく露時間||continuous for 30 min|
|Additional information||static magnetic field and AC field applied simultaneously|
|ばく露装置の詳細||exposures for vertical time-varying and static magnetic field were performed in a two-dimensional coil system; horizontal field generated by three coils consisting of 300 turns of 1 mm copper wire each, spaced 98 mm apart; electric current through the middle coil reduced by 58% to improve the homogeneity of the field; vertical field generated by two Helmholtz coils with a diameter of 346 mm and 740 turns of 1 mm copper wire, spaced 182 mm apart; coil system placed in an underground room, whose walls were build as a Faraday cage; two warm water baths shielded from the MF of the stirring motor and the heating device by a 1 cm thick 200 cm x 170 cm aluminum plate; twelve 1.5 ml tubes exposed simultaneously in a water bath in the exposure device|
|Sham exposure||A sham exposure was conducted.|
|Additional information||environmental low frequency field (40-1000 Hz): B=0.09 µT sham exposure done under the environmental static magnetic field of B=16 µT|
The predictions of the investigated model that at a frequency of 60 Hz the biological effect under investigation would significantly be altered at the amplitudes of 1.3 and 3.9 µT could not be confirmed (i.e. no effects on calcium efflux under exposure).
