[Increasing gingivoplasty efficiency by means of free palatal grafts].

The paper presents short and long-term results of surgical treatment of 80 patients with insufficient attached gingiva. The procedures included vestibuloplasty and gingival plasty with perfluorane and free gingival and subepithelial connective tissue grafts. Proposed surgical treatment method with perfluorane proved to reduce the local inflammatory reaction greatly thus decreasing perioperative morbidity and increasing the long term efficacy of treatment.

[Prophylaxis of early postoperative complications after transurethral prostatic resection (an experimental study)].

Modelling of transurethral resection (TUR) of the prostate on the animals has shown that changes in the region of postoperative wound progress by inflammatory stages--primary, then secondary alteration. These changes are confirmed by the morphological picture, shifts in enzyme levels, findings of the spectral analysis typical for systemic inflammatory reaction. Approaches to prevention of early postoperative complications based on principal components of pathogenesis are proposed.

Effect of low-intensity laser irradiation and wideband red light on experimentally ischemized myocardium.

The effect of helium-neon laser irradiation and wideband red light on electrical activity of open rat heart was examined after experimentally produced ischemia. The red light applied with the help of optical fibers modified parameters of cardiac electrical activity and intensity of lipid peroxidation in the myocardium. The effects of laser and red light irradiation differed significantly.

[New trends in surgical technologies of soft tissue wound management].

The authors performed an animal model study of postoperative wound complications using 72 white Wistar rats and 36 mongrel dogs with aseptic cut wounds, granulating wounds, and relaparotomic wounds. In the control group the wounds were closed by a conventional method; in the main group a machine stitch was performed. Wound closure in the main group was performed after approximation of wound edges with specially constructed devices.
