[The regeneration of nerve fibers after low-intensity laser irradiation].
Efficiency of myelinated fibres regeneration was studied in affecting the nerve by different lasers. 890 nm wave length irradiation 0.33 J/cm2 in dose irradiation was shown not to influence the quantity of myelinated fibres regenerating in the nerve distal region. Increase of the dose up to 9.33 J/cm2 causes 49% reduction of myelinated fibres number. Suppression of regeneration was also reported in using 1220 nm wave length laser (summary dose-0.98 J/cm2). This wave length irradiation 7.2 J/cm2 in dose was established not to impair growth and myelinization speed of nerve fibres in distal region of the nerve. Helio-neonic laser irradiation (7 J/cm2) does not affect the quantity of regenerating myelinated fibres.
