It was shown that the rate of gravitropic response in apical segments excised from the 4-day-old seedlings of flax (Linum bienne) may be substantially influenced by combined magnetic fields (CMF) of two different types: 1) CMF tuned to the parametric resonance for Ca2+; 2) CMF containing extremely weak alternating component with the values of magnetic(More)
It was found that the rate of gravitropic bending in apical segments excised from 4-day-old etiolated seedlings of flax Linum bienne is strongly and nonlinearly dependent on the value of the magnetic flux density of a static magnetic field, BDC, in the range from 0 to 350 microT. The gravitropic bending is stimulated at 0 < or = BDC < or = 2 microT and 200(More)
To learn whether the low flux density combined magnetic field (CMF) can affect rats pretreated with a dopamine agonist, the frequency spectra of cortical and hippocampal EEG were studied after intraperitoneal injection of agroclavine (50 microg/kg, Day 1) either alone (N=5) or combined with 30-min exposure to CMF (B(AC)=50 microT, f(AC)=20.9Hz, B(DC)=27.3(More)
Statistical analysis of EEG spectra averaged over 10-min intervals showed that in rats performing free behavior, peripheral administration of the acetylcholinesterase inhibitor physostigmine induced long-lasting characteristic changes (lasting tens of minutes) in the electrical activity of the dorsal hippocampus (field CA1) and the somatosensory cortex. An(More)
We determined the dependence of the effect of weak combined magnetic field (CMF) tuned to Ca2+ resonance (Ca(2+)-CMF) on the rate of gravitropic response in apical segments (25 mm long) excised from the 4-day-old seedlings of flax (Linum bienne) on the amplitude and frequency of the alternating component of Ca(2+)-CMF. The results indicate that test-systems(More)
Statistical analysis of EEG spectra averaged over 10-min periods showed that inhibitor of acetylcholinesterase physostigmine induced the long-term (tens of minutes) characteristic changes in the electric activity of the dorsal hippocampus (CA1 field) and somatosensory cortex of unrestrained rats. With increasing the physostigmine dose from 0.05 to 0.5 or 1(More)
The influence of weak magnetic fields of different types on the rate of the formation of reactive oxygen species in mouse peritoneal neutrophils has been studied. It was found that the exposure of neutrophils activated by phorbol 12-myristate 13-acetate to the magnetic field tuned to the parametric resonance for Ca2+ ions leads to a decrease in the rate of(More)
The influence of extremely weak alternating magnetic fields (EW AMF) with amplitudes of < or = 2 microT on the heart rate variability in humans has been studied. The volunteers were placed in a large- volume square coils system (2x2x2 m), which provided the exposure of the whole body to extremely weak alternating magnetic fields homogeneous in amplitude.
