[SOFT TISSUE REPAIR UNDER CONDITIONS OF EXPERIMENTAL SEPTIC WOUND.]

The effectiveness of a new complex preparation based on starch containing active copper (0.05 - 0.07 mass %) and silver 0.03 - 0.05 mass %) nanoparticles was studied in animals with experimental fill-flap septic wounds. Localized application of complex preparation (0.3 g per animal) by uniform layer on 5th, 7th, and 9th day upon wound induction led to significant reduction in wound surface (according to planimetric analysis) at all control periods, in contrast to reference group. There was statistically significant (p < 0.001) decrease in malondialdehyde (by 23%) and increase of serum enzymatic antioxidant ceruloplazmin activity (by 20.5%) in rat blood serum compared to the corresponding indexes in animals before therapy. These results are indicative of the suppression of peroxidation processes and stimulation of antioxidant system. The complex preparation exhibited positive influence on soft tissue repair processes, lipid peroxidation processes, and activity of the antioxidant system.
