AB  - An extremely low-frequency magnetic field (50 Hz, 0.5 mT) was used to investigate its possible effect on the brain of adult male Wistar rats following a 7-day exposure. The control rats were sham-exposed. Superoxide dismutase activities and production Of Superoxide radicals, lipid peroxidation, and nitric oxide were examined in the frontal cortex, striatum, basal forebrain, hippocampus, brainstem, and cerebellum. Significantly increased superoxide radical contents were registered in all the structures examined. Production of nitric oxide, which can oppose superoxide radical activities, was significantly increased in some structures: the frontal cortex, basal forebrain, hippocampus, and brainstem. Augmentation of lipid peroxydation was also observed, with significance only in the basal forebrain and frontal cortex, in spite of the significantly increased superoxide dismutase activities and nitric oxide production in the basal forebrain, and increased production of nitric oxide in the frontal cortex. The results obtained indicate that a 7-day exposure to extremely low-frequency magnetic field can be harmful to the brain, especially to the basal forebrain and frontal cortex due to development of lipid peroxidation. Also, high production of superoxide anion in all regions may compromise nitric oxide signaling processes, due to nitric oxide consumption in the reaction with the superoxide radical.

AB  - Metamorphosis time (pupa to adult eclosion time) and adult lifespan were observed in an alternating, sinusoidal, magnetic field, and compared to control. Pupae of the housefly, Musca domestica (Diptera), of approximately the same age were chosen randomly (groups of 50
individuals) and individually placed in separate glass tubes (70 mm × 11
mm) without food. The group exposed to an electromagnet (50 Hz, 6 mT) with poles of 9.3 cm × 4.8 cm (area 44.6 cm2), spaced at 7.2 cm, was placed with the magnet at a sufficient distance from the control group where the experimental magnetic field effects were not detected. The experiments were carried out successively at temperatures of 19°C and 24°C, and a 12 h light/12 h dark regime, with a controlled 60–70% relative humidity. The results show that the magnetic field significantly slowed down metamorphosis at both temperatures. The adult lifespan in the magnetic field at 24°C was statistically significantly extended with respect to control, whereas the same lifespan in the magnetic field at 19°C showed no statistically significant shortening.

AB  - The effects of chronic (7 days) exposure to an extremely low frequency magnetic field (ELF-MF, 50 Hz, 0.5 mT) on spontaneous and amphetamine-induced (1.5 mg/kg, i.p.) locomotor and stereotypic activities in adult rats were examined by open field test for 2 h on exposure days 1, 3, and 7. After 1 day of exposure to ELF-MF, the spontaneous locomotor activity was increased clearly at the first hour of observation and significantly at the second one as compared to the corresponding values in other series with ELF-MF and sham-exposed animals. After 7 days of exposure to ELF-MF, an amphetamine enhancing effect on the locomotor activity was significantly reduced at the second hour of observation as compared to that in 1-day- and sham-exposed rats treated with amphetamine. In contrast to the locomotor activity, the amphetamine-induced stereotypic behaviour in 7-day pre-exposed rats was significantly reduced at the first hour versus sham-exposed rats. While at the second hour of observation this effect was significant as compared to 1- and 3-day exposed animals (but not sham-exposed rats). Our results indicate that an extremely low frequency magnetic field is able to affect differently two types of behaviour, which are dependent on both the time course of exposure and the imbalance in the brain mediatory systems.

AB  - Exposure to extremely low-frequency magnetic field (ELF-MF, 50 Hz, 0.5 mT) for seven days did not change spontaneous motor activity of rats in the open field compared to sham-exposed animals. Pre-exposure to ELF-MF decreased locomotor and stereotypic activity induced by amphetamine (1.5 mg/kg body weight) and accordingly increased the resting time compared to sham-exposed and amphetamine-treated rats. Vertical activity (rearing) of these two groups was similar. Our results indicate that ELF-MF has different effects on some parameters of amphetamine-induced motor activity, probably due to brain region-specific effects on catecholaminergic systems responsible for movement control.

AB  - Continuous exposure to extremely low-frequency magnetic field (ELF-MF, 50 Hz, 0.5 mT) alone and combined with D-amphetamine (1.5 mg/kg) affected the reduced glutathione content in brain regions of rats. Compared to sham-exposed rats, the glutathione content in the forebrain cortex of the ELFMF-exposed rats decreased (P < 0.001), but this reverted after giving amphetamine upon ELF-MF exposure. In this group, the glutathione content was increased in the brain stem and cerebellum (P < 0.05 compared to the shame-exposed, ELM-MF-exposed, and amphetamine-treated groups). It is suggested that biogenic monoamines are involved in the reduced glutathione changes observed. The changes are not uniform in the brain regions examined.
