Objective: assessment of dynamics of reparative processes with the help of cytological examination of the preparations obtained from a conditionally aseptic wound under the action of a complex preparation based on biopolymer chitosan and metal nanoparticles. Material and Methods. A conditionally aseptic wound was simulated in 40 white outbred rats. In comparison and experimental groups cytologic assessment of dynamics of reparative processes was carried out. A number of neutrophilic leukocytes and fibroblastic row perl 00 cells in the preparations is recorded on the 3rd, 5th, 7th, 10th, 14th day from the moment of formation of the wound with the use of the immersion objective. Results. It is established, that in the comparison group the cytologic pattern of impression smear was characterized by decrease in neutrophilic leukocytes and increase in fibroblastic row cells by the 14th day from the moment of formation of the wound. In the experimental group (the use of a complex preparation) more intensive reduction of neutrophilic leukocytes and a significant increase in fibroblastic row cells by the 10th day and a complete healing by the 14th day from the moment of formation of the wound has been determined. Conclusion. When treated by a complex preparation based of biopolymer chitosan and metal nanoparticles earlier occurrence of fibroblastic row cells in preparations and a significant decrease in quantity of neutrophilic leukocytes have been observed.

The purpose of the article is to conduct comparative study of the features of reparative processes in the bone during installation of titanium implants with sandblasted exposed microarc subsequent oxidation in alkaline electrolyte using osteoinductive formulation without the use of this preparation. Material and Methods. Histologically examined tissue samples from 24 adult rabbits in the region of titanium implant with osteoinductive formulation and without after 7, 14, 28, 56 and 112 days postoperatively. Results. It has been revealed that the installation of titanium implants subjected to micro-arc oxidation in alkaline electrolytes without the use of osteoinductive preparation leads to a moderate inflammatory response and the processes of bone formation take more time. When using identical implants with osteoinductive preparation «CollapAn-gel» led to a less expressed inflammatory response and a more active process of bone formation. Conclusion. The use of titanium implants subjected to sandblasting followed microarc oxidation in alkaline electrolytes is optimally combined with osteoinductive agents as it provides the best clinical results and highlights shorter time of bone regeneration.

Objective: to determine the relation of linear parameters of the anterior cranial fossa with dimensional facial characteristics of the human skull in various craniotypes. Research Material: 100 adult skulls divided into three craniotypes have been used. Methods. Craniotopometry has been used for the measurement of the average values and the correlation model construction. Results. It has been revealed that the most significant correlation has been observed in the parameters of fleksibasilar craniotypes, in medio- and platybasilar craniotypes the multidirectional dependence of the studied parameters has been characterized as of moderate and mild degree. Conclusion. Results of research are necessary theoretical base for possible use by clinical physicians in elaboration of tactics of stereotaksichesky approach to tumoral or other pathological processes in the field of front and brain departments of a skull.
