Objective: to study the nature of the complications in the experiment (in prosthesis concerning trachea and lungs) in lavsan tracheal prosthesis. Materials and methods: An experimental study was carried out on 27 mongrel dogs, divided into groups: the first group was replaced with lavsan prosthesis of 1h1sm tracheal defect (n = 9); in the second group cartilage defect of half-rings of the trachea 4 * 1,5 cm (n = 9) was replaced; in the third group circular tracheal defect was replaced with removing of three half-rings (1.5 cm) (n = 9). The dynamics of change in clinic in animals after surgery was evaluated. All the animals were performed in the dynamics tracheoscopy At autopsy after the period of 2, 4 and 8 weeks changes in the nature of tracheal prostheses and lungs were evaluated. Results: In all the animals of the first group there were no postoperative complications, the prosthesis was covered with mucous from the lumen of the trachea, lung lesions were not observed. Animals of the second and the third group were observed. Coughing on the second day after surgery, the prosthesis deformity of varying severity, lung lesions typical to pneumonia were revealed. Conclusion: Lavsan tracheal prosthesis is acceptable only if it has small defects.

The purpose of the research: to study the relation of the voluntary visual attention to the self-regulation of different functional information comprehension systems. The object of the research: 196 individuals, aged 18-26 years, having no complaints of their health status. The techniques used: those of comprehension and measuring the pure tone length, the spatio-temporal parameters of the stimulus and the instrumental-software complex for studying the properties of attention. The results of the research have demonstrated that realizing its properties through the control functions attention exerts an active influence on the functional comprehension systems self-regulation. Conclusion: We have proved the integration of the function of attention into the self-regulation processes
