Abstract

The aim of the work was an estimation of the effect of reactive oxygen and nitrogen species on the scar tissue fragment ex vivo. It was found that the treatment of scar tissue fragments by gas flow from singlet oxygen and nitric oxide generators leads to change dielectric properties of the tissue and the intensity of free radical processes. The peculiarity of the singlet oxygen action is a moderate increase permittivity. The NO effect at a concentration of 20 ppm is associated with a marked increase in permittivity and conductivity.
