[Increasing the scar strength after preventive skin irradiation with low-intensity laser].

In the experiment on 218 white rats, it was established that preliminary influencing upon the site of a future incision with the infrared laser radiation in constant regime within the range of from 1 to 150 mW (dosage of radiation per 1 field of 0.06-9.3 J/cm2) facilitated pronounced stimulation of the processes of collagen formation and significant increase in strength of a forming scar. In increasing the power of radiation, the reparative processes in a wound are slowed and disturbed; in power of 250 mW, a wound heals by second intention, in average, after (32.6 +/- 3.2) days.
