[Characteristics of rehabilitation in patients with rheumatic diseases]. / Ossobennosti vosstanovitel'nogo lecheniia bol'nykh revmatologicheskogo profilia.

The paper deals with problems of rehabilitation of patients with rheumatoid arthritis, osteoarthrosis and systemic lupus erythematosus. These problems are rather topical in view of high prevalence of rheumatic diseases, their severe course and a high rate of invalidization at the most productive age. Relevant multifactorial therapeutic measures should be staged, aimed at lowering and stabilization of the disease activity. The role of updated medication, joint surgery, diet therapy, etc. is shown.

[Radiation loading, radiation-induced diseases and suicide values in a region adjacent to a nuclear testing ground]. / Radiatsionnaia nagruzka, radiatsionno-indutsirovannye vidy patologii i pokazateli suitsida v prilezhashchem k ispytatel'nomu iadernomu poligonu regione.

Radiation effects on the population health at a territory adjacent to the Semipalatinsk nuclear testing grounds were studied. Immunosuppression and suppression of nonspecific defense factors, induced by radiation from the testing grounds, determine the extension of physiological lability range, accelerate the natural involution processes, and create psychoemotional stress. The totality of radiation-induced general physiological effects with pronounced dose dependence of their incidence and intensity represents a co-factor of suicide.

[Tests of durability characteristics of osteosynthesis of femoral neck fractures by different fixators under static and dynamic loading]. / Ispytaniia prochnostnykh kharakteristik osteosinteza perelomov sheiki bedra raznymi fiksatorami pri staticheskikh i dinamicheskikh nagruzkakh.

Test bench experiments on the models of femoral neck bone fractures with the use of various kinds of latches has been carried out for evaluation of durability characteristics of the osteosynthesis, using universal test machine "Zwick-1464". 40 preparations of proximal-diaphysis parts of the femoral bone from 28 females and 12 males (mean age 71 years) were used one day after death. The models of basal, transcervical and subcapital fracture were formed with the angle between its planes and horizontal plane (the angle of Pauel's) 30, 40 and 70 degrees. The models of fractures underwent static and dynamic loads, the results being fixed automatically in graphics. The obtained data have confirmed the dependence of the stability of the osteosynthesis by tested fixators on the size of Pauels' angle: the more was this value the less was the firmness of the junction. Dependence of the firmness of fixation of bone fragments on location of the fracture in femoral neck was noted. The differences of durability characteristics of created constructions in basal, and transcervical fractures of types I and II by Pauels are insignificant. The authors think that the least invasive mode for fixation among tested constructions is osteosynthesis with V-shaped bunch of needles, which produced minimal trauma for bone tissue and created resilient tension in the system of bone fixator (latch), which is especially important in osteoporosis.

[Effect of hypokinesia on bone tumor induction]. / Vliianie gipokinezii na induktsiiu opukholei kostei.

The effects of different periods of hypokinesia on the development of 7.12-dimethyl-benzoanthracene-induced osteosarcoma of shinbone were studied in 148 rabbits. The time of induction was found to decrease considerably - from 197.6 to 113.9 days. This may be attributed to hypokinesia's constituting a stress, which involves release of adrenocortical hormones, atrophy of the thymus and reduced cellular immunological vigor.
