Diffuse lesions of the anterior interventricular artery (AIVA) at different levels were diagnosed in 27 out of 417 patients operated for post-infarction aneurysm of the left ventricle (PIALV). During the preoperative period coronography, ventriculography, ultrasonic examination of the heart were made in all the patients, one-photon emission computed tomography with 123I-iodopent was used for radioisotope investigation of perfusion and metabolism of the myocardium. The presence of PIALV, diffuse atherosclerotic lesion of AIVA and viable myocardium in its basin was taken as an indication for autovenous plasty of the artery with the following shunt of the left intrathoracic artery and resection of PIALV.

The gamma decay of the giant dipole resonance (GDR) in the 132Ce compound nucleus with temperature up to approximately 4 MeV has been measured, using the reaction 64Ni + 68Zn at E(beam) = 300, 400, and 500 MeV. The gamma and charged particles measured in coincidence with recoils are consistent with a fully equilibrated compound nucleus emission. The GDR width, obtained with the statistical model analysis, is found to increase almost linearly with temperature. This increase is rather well reproduced within a model including thermal shape fluctuations and the lifetime of the compound nucleus.

The features of pilot organism adaptation to the conventional for this professional group hypoxic load were studied by mathematical analysis of heart rate. Significant alteration of structure and amount of correlation intercommunications between the indices of the heart rate in pilots of different age and state of health was established.

Interrelation features of professionally important psychophysiological qualities for candidates to flying training with a different suitability level were studied in research by means of the factorial analysis. It is revealed that the factorial structure of psychophysiological qualities for persons with a various suitability degree to flying work differs appreciably, that has allowed to allocate the characteristics determining a "suitability" and "unfit" degree to professional work. The two-stage and one-stage procedures of professional psychophysiological selection, and also those realizations of initial selection and monitoring of adjunct pilot's psychophysiological functions which are taking into account the purposes, technologies and opportunities of the selection organization in the given establishment are offered.

Some early symptoms of devascular femoral head necrosis are covered in the paper together with the results of surgical treatment of 48 cases. Both extra- and intraarticular operations were performed. The extraatricular interventions proved to be the best: intertrochanteric medializing osteotomies, drilling of the canal with introduction of cortical bone grafts into the femoral neck and head and tunnelization followed by the replacement of the femoral head defect with autospongy bone tissue.

The author reports the results of treatment in 58 patients with oblique aplastic pseudarthrosis of tubular bones diaphyses of the lower limbs. For treatment extrafocal with counter-lateral compression by means of pins with bearing surfaces. By the present time nearly in all patients (52 of 58) with the mentioned complications such kind of treatment resulted in rehabilitation of the main motion-bearing function of the extremity.

The experience of the treatment of 107 patients with nonunited open and gunshot fractures of the crus bone complicated by osteomyelitis is described. In 100 patients osteomyelitis was liquidated, in 97 patients consolidation of bone fragments was achieved, the supporting ability and joint movements were restored.

By using a complex of investigation methods variants of branchingout of the spinal cord and spinal ganglia blood supply sources and their anatomo-topographic interrelations were discerned in 140 preparations of lumbar spinal ganglia obtained from human cadavers of both sexes and different age. With the help of anastomoses these sources form a specific arterial circle around the ganglion. The radicular arteries are noted to be non-equivalent. The annular architectonics of the blood vessels is considered as a morphological manifestation of a functionally reliable blood supply to the border area between the central and peripheral divisions of the nervous system.
