[Effect of laser radiation on the posttraumatic recovery of the interneuronal connections in the sympathetic trunk]. / Vliianie lazernogo izlucheniia na posttravmaticheskoe vosstanovlenie mezhneironnykh sviazei simpaticheskogo stvola.

Low energetic laser radiation produces stimulating influence on posttraumatic regeneration of interneuronal connections of the sympathetic trunk. Local effect of the low energetic laser with exposition of 25 sec., power of the incident ray 16 mVt/cm2 increases the cause of reparative regeneration of sympathetic preganglionic fibers. Restoration of the cranial cervical ganglion (CCG) connections with the spinal cord takes place 5-6 days earlier comparing with the control. Localization and structural organization of the spinal initial neurons is stated, their processes reach the CCG.

[Reaction of the peripheral nervous system elements to the action of laser irradiation]. / Reaktsiia élementov perifericheskoi nervnoi sistemy na vozdeistvie lazernogo izlucheniia

The effect of light of the helium neon laser LG-75 with the output power 25mvt and the generated wave length 6328 A upon reparative processes in the neuromuscular apparatus was studied in rats in dynamics after neurotomy of the ischiatic nerve. Neurohistological (staining after Bielschowski-Gross, Spielmeier, Weigert-Pal) and electrophysiological (chronaximetry, "force-duration" index, electromyography) methods were used. The material was processed in a computer. A stimulating effect of the applied low-energy laser radiation on the regeneration of the ischiatic nerve was established.
