Effects of ELF (1–120 Hz) and modulated (50 Hz) RF fields on the efflux of calcium ions from brain tissue in vitro
Tập 6 Số 1 - Trang 1-11 - 1985
AbstractWe have previously shown that 16‐Hz, sinusoidal electromagnetic fields
can cause enhanced efflux of calcium ions from chick brain tissue, in vitro, in
two intensity regions centered on 6 and 40 Vp‐p/m. Alternatively, 1‐Hz and 30‐Hz
fields at 40 Vp‐p/m did not cause enhanced efflux. We now demonstrate that
although there is no enhanced efflux associated with a 42‐Hz field at 30, 40,
50, or ...
Effects of magnetic field on the antioxidant enzyme activities of suspension‐cultured tobacco cells
Tập 28 Số 1 - Trang 42-47 - 2007
AbstractEffects of magnetic fields (MFs) on the activities of antioxidant
enzymes of suspension‐cultured tobacco cells were investigated. Compared with
the control cells, exposure of the cells to static MF with the magnitudes of 10
and 30 mT for 5 days, 5 h each day, increased the activity of superoxide
dismutase (SOD). In contrast, the activity of the catalase (CAT) and ascorbate
peroxidase (APX)...
Chromosomal aberrations in human amniotic cells after intermittent exposure to fifty hertz magnetic fields
Tập 15 Số 4 - Trang 293-301 - 1994
AbstractOur recent studies have shown a significant increase in the frequency of
chromosomal aberrations in human amniotic cells after exposure to a sinusoidal
50 Hz, 30 μT (rms) magnetic field. To evaluate further interactions between
chromosomes and electromagnetic fields, we have analyzed the effects of
intermittent exposure. Amniotic cells were exposed for 72 h to a 50 Hz, 30 μT
(rms) magnetic...
On the “unreasonable” effects of ELF magnetic fields upon a system of ions
Tập 23 Số 7 - Trang 522-530 - 2002
AbstractA recent experiment on a physical, nonbiological system of ions at room
temperature has proved that microscopic ion currents can be induced by applying
simultaneously two parallel magnetic fields, one rather weak static field, $\vec
B_0$ and one much weaker alternating field, $\vec B_{ac}$, [Bac ∼ 10−3 B0] whose
frequency coincides with the cyclotron frequency $v\, = \,qB_0 /2{\pi}m$ of th...
Effects of extremely low frequency magnetic field on fertility of adult male and female rats
Tập 22 Số 5 - Trang 340-344 - 2001
AbstractTo investigate the effects of an extremely low‐frequency (ELF) magnetic
field on their fertility, adult male and female Sprague‐Dawley rats were exposed
to a 50 Hz sinusoidal magnetic field of approximately 25 μT (rms) for 90 days
before they were mated with unexposed counterparts. Exposure to a 50 Hz field
reduced male rat fertility. The number of pregnant females was reduced when
mated w...
Effects of weak static magnetic fields on endothelial cells
Tập 31 Số 4 - Trang 296-301 - 2010
AbstractPulsed electromagnetic fields (PEMFs) have been used extensively in bone
fracture repairs and wound healing. It is accepted that the induced electric
field is the dose metric. The mechanisms of interaction between weak magnetic
fields and biological systems present more ambiguity than that of PEMFs since
weak electric currents induced by PEMFs are believed to mediate the healing
process, w...
Effect of 0.25 T static magnetic field on microcirculation in rabbits
Tập 23 Số 3 - Trang 224-229 - 2002
AbstractWe showed previously in rabbits that 0.2 and 0.35 T static magnetic
field (SMF) modulated systemic hemodynamics by arterial baroreceptors. We now
have measured the effect of 0.25 T SMF on microcirculation within cutaneous
tissue of the rabbit ear lobe by the rabbit ear chamber (REC) method. Forty
experimental runs (20 controls and 20 SMF) were carried out in eight different
rabbits with an...
Transcriptional patterns in the X chromosome of Sciara coprophila following exposure to magnetic fields
Tập 8 Số 1 - Trang 1-7 - 1987
AbstractWe previously demonstrated that exposure of salivary gland cells of the
dipteran, Sciara coprophila, to either asymmetrical or symmetrical changing
magnetic fields results in an increase in the incorporation of radioactive
uridine into RNA. The present report is an analysis of the grain count
distribution over the X chromosome of Sciara in transcription autoradiograms
following exposure of...
Effects of mobile phone electromagnetic fields: Critical evaluation of behavioral and neurophysiological studies

In vitro exposure apparatus for ELF magnetic fields
Tập 25 Số 8 - Trang 582-591 - 2004
AbstractFor in vitro studies on the effect of extremely low frequency (ELF)
magnetic field exposures in different laboratories, a programmable, high
precision exposure system enabling blinded exposures has been developed and
fully characterized. It is based on two shielded 4 coil systems that fit inside
a commercial incubator. The volume of uniform B field exposure with 1% field
tolerance is 50% l...
