[Hemodynamics in soft tissues after upper third of the leg lengthening by Ilizarov osteosynthesis technique].

An experimental study has been performed. The leg was lengthened in 12 adult mongrel dogs by transosseous distraction osteosynthesis in the zone of upper third of the leg bone shaft by 14-18% of the segment length using the rate of 1.0 mm for 4 times.

[Plasma leptin level in patients with bronchial asthma].

The aim of this study was to measure plasma leptin level in patients with bronchial asthma (BA) and compare it with clinical features of the disease. It included 21 healthy subjects, 9 patients with extrapulmonary allergy, and 18 with partially controllable BA. Plasma leptin was measured by ELISA.

[A method for determining the impulsive force range in experimental simulation of various long bone fractures].

The dependence of the bone fracture characteristics on the impulsive force parameters was studied. An original method for quantitative assessment of the traumatic impulsive force was suggested. Preliminary experimental studies in osseous specimens from dogs revealed the range of the impulsive force parameters to be used in experimental simulation of long bone fractures.

[Peculiarities of repair osteogenesis during the transverse traction of the longitudinal diaphysis fragment under the conditions of intraosseus vessel preservation].

The application of technique for obtaining the tibial fragment (split) with a preserved vascular network of the nutrient artery and its branches, that participate in the blood supply of this bone area, permits to detect significant osteogenetic potential of both endosteum and undifferentiated bone marrow cells. Under these conditions it was possible to increase the bone thickness 2 to 3 times in short time. The regeneration process in this case is characterized by a rapid course and formation of large massive of cancellous bone.

[Distraction osteosynthesis in occlusive diseases of the limb arteries].

The method of distraction osteosynthesis was used in 265 patients with arterial occlusions of the upper and lower limbs, which developed due to obliterative thromboangiitis and atherosclerosis. Surgical treatment of patients with distal type of occlusive disease of the arteries was followed by steady compensation of ischemic disturbances after bone chip formation and its dosage across transfer with formation of distraction regenerate transforming into mature osseous tissue. Favourable results of the treatment were observed in 236 patients (88.
