[The mechanism of skeletal musculature contraction induced by pulses of a high-intensity magnetic field]. / K mekhanizmu sokrashcheniia skeletnoi muskulatury, vyzvannogo impul'sami magnitnogo polia vysokoi intensivnosti.

Acute experiments on nembutal-anesthetized cats (50 mg/kg) were employed to investigate the effect of 1 T pulsating magnetic field (PMF) on neuromuscular system of the leg. Special techniques (tubocurarine administration, PMF exposure of the isolated nerve before and after cold blockade, immersion of the isolated nerve into the media with different surface area and electrical conductance) furnished evidence on muscular contractions resultant exclusively from stimulation of the motor fiber. The generation of the potential effect was recorded under the conditions of the nerve trunk contact with a conducting medium with surface area sufficient for appearance of the threshold potential difference in its periphery.

[Descending modulation of monosynaptic reflexes after traumatic injury of the cat spinal cord]. / Niskhodiashchaia moduliatsiia monosinapticheskikh refleksov posle travmaticheskogo povrezhdeniia spinnogo mozga u koshek.

Studies of the descending modulation of monosynaptic reflex responses have revealed that electrical stimulation of dorsolateral, ventrolateral and ventral funiculi in C2 facilitated and suppressed test responses of intact animals, but evoked only suppression of spinal reflexes after injury of the spinal cord. The obtained data have shown that descending pathways which transmit facilitatory influences are more vulnerable to injury of the spinal cord.
