[Immunological and biochemical indices during the use of hyperbaric oxygenation for treating patients with jaw deformities].

Analysis of changes in the immunologic and biochemical parameters in the patients operated on for congenital deformations of the maxillary bones and poorly joined fractures has shown an increase of the immunologic reactivity under the effect of hyperbaric oxygenation therapy administered after surgery to patients with initially reduced levels of these parameters. Urinary excretion of hydroxyproline was found unchanged in patients with maxillary deformations.

[The morphofunctional characteristics of the dystrophic and reparative processes in experimental autodermoplasty using a CO2 laser].

The aim of this work was research of the morphofunctional features of rabbit free skin flaps after CO2 laser and scalpel interventions. pO2, histologic and histochemical data were analyzed. The results evidence an insignificant delay of the pO2 growth in laser-treated flaps early after surgery.

[Autologous blood transfusion and the problem of "safe" blood].

A conception of "safe" blood has been proposed based on autohemotransfusions with the use of the methods of preparation of autologous blood, preoperative isovolemic hemodilution and intraoperative blood salvage. For the latter method special apparatus are needed, while the two former methods are easily performable without complex equipment and high expenses. The wide use of autohemotransfusions is considered as the most reasonable alternative under conditions of diminution of donor number, increased hazard of transmission of some infections through homologous blood transfusions.
