[Structural and functional characteristics of recovery of the severed sciatic nerve exposed to pulsed magnetic field]. / Strukturno-funktsional'nye kharakteristiki vosstanovleniia pererezannogo sedalishnogo nerva pri deistvii impul'snym magnitnym polem.

In rabbit experiments after cross-cutting the sciatic nerve with its subsequent perineural suture, the authors studied whether the structure of injured nerve fibers could be recovered on exposure to an impulse magnetic field (IMF) of high intensity (1.2 T). On exposure to IMF, the processes of nerve fiber myelinization were found to proceed much more rapidly in the rabbits operated on and the area of a connective tissue scar showed a more direct growth of nerve fibers of the center to the periphery. Light optic microscopy indicated that IMF of the intensity used produced no damaging effects on nerve tissue.

[The action of a pulsed magnetic field on the electrical resistance of the skin]. / Deistvie impul'snogo magnitnogo polia na élektricheskoe soprotivlenie kozhi.

The skin of 32 rabbits and 10 patients (7 males and 3 females aged 32-48) was exposed to impulse magnetic field (IMF) with intensity of 1.0-1.5 T and frequency of 45 paired impulses a minute. The 5-minute exposure resulted in a 50% decrease in the skin electrical resistance both in patients and animals. On aftertreatment minute 2 the resistance started recovering and returned to the baseline on minute 6 in animals and 4 in patients. Changes in electrical resistance of the skin are attributed to emergence of IMF-related electrical induction.

[The action of an impulse magnetic field on the motor function recovery of the peripheral nerve trunks]. / Deistvie impul'snogo magnitnogo polia na vosstanovlenie dvigatel'noi funktsii perifericheskikh nervnykh stvolov.

The cut sciatic nerve trunk was sutured perineurally to study in chronic rabbit experiments of the neuromuscular functional recovery upon the exposure to impulse magnetic field with the intensity 1.2 T. Nonexposed animals served control. Myographic activity of reinnervated crural muscles in the irradiated animals recovered two times more rapidly compared to the controls, so did motor function of the limb operated on. It is inferred that impulse magnetic field produces therapeutic and preventive effect on neurodystrophy resultant from the nerve dissection.

[The efficiency of the action of a pulsed magnetic field on the neuromuscular apparatus]. / Effektivnost' deistviia impul'snogo magnitnogo polia na nervno-myshechnyi apparat.

The effect of pulsing magnetic field on the rabbit neuromuscular system was compared with the effect of direct electrical stimulation. The electrophysiological data demonstrated slight difference between myograms after magneto- and electrostimulation. Magnetostimulation was shown to have an advantage in the myogram estimation and contactless action.

Upon the analysis of electrophysiological findings obtained in acute experiments on rabbits exposed to impulse magnetic field (1.2 T) compared to direct electric stimulation demonstrated equal worth of the two stimulations by bioelectrical myographic response. Impulse magnetic stimulation under relevant experimental setting was occasionally even more effective. It also had the advantage of noncontact action. The results promote the study of the above magnetic field effect on the peripheral nervous system with the aim of recovering locomotor function.
