[Effect of a low-intensity CO2 laser on the process of reparative regeneration of experimental wounds].

The authors studied the effect of CO2 laser with an energy density ranging from 0.1 to 300 mVt/cm2 on reparative regeneration of experimental wounds. The criteria of the efficacy of laser therapy were the wound surface area, the surface of the necrotic area, cellular composition and the content of collagen and glycosaminoglycans in the granulation tissue. Laser radiation with an energy density of 0.5 and 4 mVt/cm2 and exposure of 2 min appeared to produce the most beneficial effect on reparative regeneration.
