Abstract

In two experiments, male rats that had been exposed to an ELF (0.5 Hz), 3–50 gauss rotating magnetic field (RMF) for 21–30 days, displayed significantly (p < 0.05) greater ambulatory behavior (activity) than the control group in an open field test, when removed from the RMF. In a third experiment rats were exposed to a different RMF apparatus (3–30 gauss), and tested in a different open field for longer duration. Again the RMF-exposed group displayed greater activity (p < 0.10) than the control group.

Zusammenfassung

In zwei Untersuchungen zeigten männliche Ratten,die einem ELF (0,5 Hz) 3–50 Gauss rotierenden magnetischen Feld (RMF) für 21–30 Tage ausgesetzt wurden, in einem Open-Field Test signifikant (p < 0,05) mehr Bewegungsaktivität als die Kontrollgruppe,nachdem sie von dem RMF entfernt wurden. In einer dritten Untersuchung wurden Ratten in einem anderen RMF Gerät gehalten und in einem anderen Open-Field für längere Zeit getestet. Wieder zeigte die Gruppe, die dem RMF ausgesetzt war, mehr Bewegungsaktivität (p < 0,10) als die Kontrollgruppe.

Resume

Lors de deux essais, on a placé des rats mâles dans un champ magnétique tournant (CMT) de 3 à 50 gauss et des très basse fréquence (FTB) (0,5 Hz). Après 21 à 30 jours de ce traitement, on les a remis dans des conditions normales. Leur activité (marche) était plus élevée que celle d'un groupe de contrôle et cela de façon significative (p < 0,05). Dans un troisième essai, d'autres rats furent placés dans un autre appareil (3 à 30 gauss) et examinés ensuite dans un autre champ ouvert sur une plus longue période. Le groupe traité a déployé dans ce cas également une plus grande activité qu'un groupe de contrôle (p < 0,10).
