RESUMEN
Therapy of wounds and inflammatory diseases with NO-containing gas flows (NO-CGF) has proved to be effective in a longterm clinical practice. Plasma-chemical generation of nitric oxide occurs from atmospheric air in Plason device. For the purpose of modification and improvement of NO-therapy, effects of various physicochemical parameters of the NO-CGF on inflammatory and reparative processes in wounds were studied. Treatment of planar full-thickness skin wounds in laboratory rats was analyzed with morphological, immunohistochemical, morphometric and statistical methods. The study showed that the Plason device and the experimental device, which differs from Plason by the NO-CGF temperature, significantly reduce inflammatory and enhance regenerative processes in the wounds. The NO-CGF with an ambient temperature generated by the experimental device has noticeably facilitated the wound healing in direct ration to a nitric oxide content and flow velocity at the area of application. Temperature did not affect the course of wound healing process. The development of a new device for NO-therapy may be of use for both physicians and patients.
