The article provides information, over the past 5 years, on the existing methods of scar tissue correction. Treatment of scar tissue depends on its shape, etiology, predisposition, concomitant somatic diseases. It also provides information on the treatment of soft tissue scars, depending on their location and the patient's phototype.
Subject of the inquiry: the protective carcass of a cabin of universal wheel tractor-cultivator.
Aim of the inquiry: design procedure working out on durability and the substantiation of strength parameters of the carcass of cabin of tractor of a class 1.4.
Methods of inquiry: Researches were spent by methods of mathematical and experimental modeling of deflections of elements of the bearing carcass of the cabin of the tractor at overturning in quasi-static to statement
The results achieved and their novelty:
- the mathematical model of calculation of the carcass of the cabin of the tractor on durability is made;
- the design procedure of the protective carcass of the cabin of the tractor on durability taking into account process of distribution of a zone of plastic deformation on length and height of cross-section section of elements of the construction of the carcass;
- Dependences strength properties of rod elements of the construction of the carcass from the bend and curvature moment.
Practical value: the cabin design procedure on the durability is developed, allowing at a design stage and operational development of a design with high degree of reliability to receive demanded strengthening characteristics (the Patent for the computer program № DGU 01583). The multiple analysis of the construction of the cabin of tractor TTZ 80.20 is carried out and the new carcass of the cabin of the tractor (the Patent for utility model № 1'AP 00563) is offered.

Subject of the inquiry: 148 patients with degenerative dystrophic diseases of the hip joint, of them 103 with osteoarthritis and 45 with avascular necrosis of the femoral head.
Aim of the inquiry: improvement of the diagnosis of degenerative-dystrophic diseases of the hip using possibilities of ultrasonography and magnetic resonance imaging.
Methods of research: X-ray, ultrasonography and magnetic resonance imaging.
The results achieved and their novelty: For the first time, the role of ultrasonog-aphy and magnetic resonance imaging in osteoarthritis and avascular necrosis of the hip was established in comparison with conventional X-ray. The result have shown that sensitivity of ultrasonography in osteoarthritis was low (57.7%) in the detection of femoral head deformation. In avascular necrosis of the hip detection of femoral head deformation was revealed better - 89.7%, which can be explained by differences in the mechanism and localization of deformation in these diseases. Ultrasonography was quite sensitive to changes of the joint capsule both in osteoarthritis and avascular necrosis, the sensitivity 86.0% and 84.6% respectively. MRI was superior to X-ray in the assessment of space orientation of the joint surfaces, necrosis zone, synovitis, subchondral cysts, structural changes and joint effusion. X-ray was more preferable for the detection of ostephytosis, subchondral sclerosis and changes of the joint space in osteoarthritis.
Practical value: of the work consisted in the concretization of sonographic and MRI signs of degenerative dystrophic diseases of the hip joint and in the suggested algorithm of using radiological methods for establishing the nature of hip joint pathology.
Degree of inculcate: the results of research were introduced in the Radiology Department of First Tashkent Medical Institute and the Department of Large Joint Pathology Department of the Traumatology and Orthopedy Research Institute.
Sphere of usage: radiology, traumatology and orthopedy, rheumatology.
In peacetime, non-firearms of the lower jaw are usually observed. They arise as a result of resection or disarticulation of the jaw (in connection with a benign or malignant tumor), its elongation in the elimination of underdevelopment, after suffering osteomyelitis or overly extensive and uneconomical sequestrectomy, after an accidental trauma, etc. [6,9]. Among the many reasons that lead to the occurrence of defects in this localization, oncological pathology takes the first place, with malignant tumors accounting for up to 16% of cases, benign ones - up to 42.9% [10, 11, 12]. Traumatic injuries, gunshot and non-gunshot wounds of the maxillofacial region, leading to defects of the lower jaw of various lengths, occur in 28.5% of cases [7].
