SPECIAL ASPECTS OF MICROELEMENT COMPOSITION OF THE BONE TISSUE IN TRANSOSSEOUS DISTRACTION OSTEOSYNTHESIS BY ILIZAROV METHOD UNDER THE CONDITIONS OF HIGH ALTITUDE

In an experiment in low-mountain conditions, the features of changes in the structure of bone tissue in the zone of a gunshot fracture of the shank diaphysis were studied. It was revealed that when using the compression-distraction method according to G.A. Ilizarov, a pronounced angiogenic effect is observed, an improvement in reparative processes. The results obtained confirm the need to use the method of extrafocal compression-distraction osteosynthesis to accelerate the healing of gunshot fractures of tubular bones.

And Function

Methods and outcomes of treatment of calcaneous deformities and defects (102 patients, 112 feet) of different etiology are presented. Treatment technique was extrafocal compression-distraction osteosynthesis by Ilizarov. Condition of the foot was monitored using radioisotopic, biomechanical and radiologic examinations. Anatomic and functional results of treatment depended upon the severity of the initial pathologic changes in bone and soft tissues, presence of concomitant osteomyelitis in the remission phase as well as on gait stereotype and biomechanical relation of the overlying segments. Preference of transosseous osteosynthesis by Ilizarov for the treatment of calcaneous defects and deformities accounted for the possibility of dosed correction and functional loads as well as by the favorable effect on bone tissue blood supply.

AbstractThe Hα filtergrams obtained at Tjan-Shan High Altitude Observatory near Alma-Ata (Moscow University Station) were measured in order to specify the bright rims contrast at different points along the line profile (0.0; ± 0.25; ± 0.5; ± 0.75 and ± 1.0 Å). The mean contrast value in the line center is about 25 percent. The bright rims interpretation as the bases of magnetic structures supporting the filaments is suggested.

Particulate Contaminants

All serious electron microscopists at one time or another have been concerned with the cleanliness and freedom from artifacts of thin film specimen support substrates. This is particularly important where there are relatively few particles of a sample to be found for study, as in the case of micrometeorite collections. For the deposition of such celestial garbage through the use of balloons, rockets, and aircraft, the thin film substrates must have not only all the attributes necessary for use in the electron microscope, but also be able to withstand rather wide temperature variations at high altitude, vibration and shock inherent in the collection vehicle's operation and occasionally an unscheduled violent landing.Nitrocellulose has been selected as a film forming material that meets these requirements yet lends itself to a relatively simple clean-up procedure to remove particulate contaminants. A 1% nitrocellulose solution is prepared by dissolving “Parlodion” in redistilled amyl acetate from which all moisture has been removed.
