Comparative study of complex powdery preparations for soft tissue regeneration
The aim: comparative study of regenerative activity of powdery preparations for local treatment of soft tissue injuries developed from copper and silver nanoparticles in comparison with traditional powders containing antibiotics within the conditions of an experimental conditionally aseptic wound. Material and Methods. The investigation was carried out on 80 albino rats with an experimental conditionally aseptic wound. Copper and silver nanoparticles obtained by the plasma-chemical method, sterile starch, zinc oxide, Baneocin were used. Planimetric and bacteriological research methods were applied. Results. Treatment with the developed preparations in comparison with the traditional ones containing antibiotics supplied more effective course of reparative processes as evidenced by the data of the planimetric indices. Conclusion. Besides the developed preparations due to the evident antibacterial action supplied reliable prevention of the secondary infection which is a compulsory condition for the course of reparative regeneration processes. The use of metal nanoparticles for this purpose allowed to prevent the adverse reactions which are characteristic of similar preparations containing antibiotics.
