The role of laser biostimulation in early post-surgery rehabilitation and its effect on wound healing.

Background: The aim of this paper is to investigate whether laser biostimulation starting on the first day after surgery of the brachial plexus or peripheral nerves has a positive therapeutic effect on wound healing.

Material And Methods: Surgical procedures were carried out on 44 male Wistar rats. The animals were divided into a control group (Group 1), where the surgical wounds were allowed to heal spontaneously, and an experimental Group 2, where the wounds were exposed to laser irradiation with the following parameters: wavelength 810 nm, power 100 mW, energy 15 J, laser exposure surface 3 cm(2), single application time 2 min.

[Evaluation of nonabsorbable surgical sutures in tubal anastomoses with use of microsurgical techniques. An experimental study].

In the paper there have been evaluated synthetic nonabsorbable surgical sutures--PROLENE. The valuation concerned their usefulness to carrying out the operations of oviducts with use of microsurgical technique. It consisted in determination of biocompatibility degree of analyzed sutures within tubal tissues and also their technical utility to this kind of procedures.

[Evaluation of long-time resorption surgical sutures in tubal anastomoses with use of microsurgical techniques. An experimental study].

In the paper there have been evaluated synthetic absorbable surgical sutures--MAXON, of long time of their resorption in an organism. The valuation concerned their usefulness to carrying out the operations of oviducts with use of microsurgical technique. It consisted in determination of biocompatibility degree of analyzed sutures within tubal tissues and also their technical utility to this kind of procedures.

[Evaluation of short-time resorption surgical sutures in tubal anastomoses with use of microsurgical techniques. An experimental study].

In the paper there have been evaluated synthetic absorbable surgical sutures--Coated VICRYL, of short time of their resorption in an organism. The valuation concened their usefulness to carrying out the operations of oviducts with use of microsurgical technique. It consisted in determination of biocompatibility degree of analyzed sutures within tubal tissues and also their technical utility to this kind of procedures.

Ceramic corundum materials with modified surface as implantation materials.

Investigations on implants have proved that not only the kind of material structure, but also the surface character of grafts influences the local reaction of biomaterials. In recent years electrochemical reactions on implants surface leading to the so called zeta potential arouse interests. Applications of these properties has made us carry on experiments on use of biomaterials with active potential on their bio-compatibility.
