An experimental study of the physical processes in a thin plasma jet produced by the pulsed discharges in the capillary with evaporated wall is described. The losses in mass from capillary wall as well as the transferred charge are accurately measured. The velocity of plasma jet propagation is measured, too. The current structure in plasma is studied. It is(More)
Vestibular dysfunction was studied in 95 patients with initial cerebral circulatory insufficiency (CCI) stage I and II. Sinusoidal rotation proved highly effective in staging the disease, as initial CCI responses with vestibular hyperreflexia to sinusoidal rotation with closed eyes. With CCI progression, some patients demonstrated inhibition of vestibular(More)
We have found that two important brain synaptic receptor systems are very sensitive to the influence of low intensity microwaves. Both the excitatory glutamatergic and the inhibitory GABAergic are affected by microwave exposure. Power densities higher 50 microW/cm2 caused changes in the binding properties of these receptors to agonists. Low frequence(More)
The effect of 800 mHz microwaves of 0, 3, 5, 7, 16, and 30 Hz modulation on GABA receptor concentration in rat brain cortex has been investigated. Irradiation of the whole body at a modulation frequency of 16 Hz readily decreases the GABA receptor concentration. Irradiation at other modulation frequencies is ineffective. Irradiation of the whole body(More)
It has been shown that tetrodotoxin inhibits GABA-receptor binding of muscimol with solubilized membranes of the rat brain in a competitive manner, with the inhibition constant amounting to about 3 nM. Muscimol has been also demonstrated to competitively inhibit 3H-tetrodotoxin binding with the same drug.
The effect of methionine-enkephalin (Met-Enk) on responses of rat brain neostriatum neurones to microiontophoretic application of glutamate was studied in experiments with extracellular recording of spike activity. Met-Enk administered by microiontophoresis was shown to depress the glutamate-induced responses. In parallel experiments with synaptic membranes(More)
It was shown that high-frequency electromagnetic field increases the conductivity of ionic channels formed by the synaptic membrane fragments, which bind glutamate, in a bilayer lipid membrane. Heating of the whole electrolyte in a cell, under the effect of the electromagnetic field applied, was minor to be responsible for the effects observed.
