[Experimental validation of the use of an ultrasonic surgical instrument in neurophysiology]. / Eksperimental'noe obosnovanie primeneniia ul'trazvukovogo khirurgicheskogo instrumenta v neirofiziologii.

The effect of ultrasonic and surgical instruments on nervous tissue in chronic experiments on the cats were investigated with electrophysiological and morphological methods. The authors compared the results of removal of the neocortex zones using ultrasonic and surgical instruments or routine methods. Electrophysiological and morphological studies have shown small injury effects made by ultrasonic and surgical instruments on the surrounding brain tissue.

[Blood aggregation and the system of microcirculation in experimental atherosclerosis, its spontaneous regression and hemosorption]. / Agregatnoe sostoianie krovi i sistema mikrotsirkuliatsii pri éksperimental'nom ateroskleroze, ego spontannoi regressii i gemosorbtsii.

Blood aggregate state and microcirculation were studied during development and spontaneous regression of experimental atherosclerosis and following hemosorption. It has been shown that experimental atherosclerosis is not only accompanied by changes in blood lipid composition, but also by disturbances in the structure and function of microcirculatory bed. Normalization of blood lipid composition and recovery of blood aggregate state and microcirculatory bed structure and function were not observed during spontaneous regression. Repeated hemosorption enhances atherosclerosis regression, normalizes lipid composition of blood and biological membranes and promotes the recovery of microcirculation.

[Structure and development of the microcirculatory bed of the pleural villi in man and animals]. / O stroenii i razvitii mikrotsirkuliatornogo rusla plevral'nykh vorsin cheloveka i zhivotnykh.

The structure of the microcirculatory bed in the pleural villi was studied by the method of impregnation with silver nitrate, after V.V. Kuprianov. In human and animal mediastinal pleura, the microcirculatory ways are regulated within polymerously repeated complexes--moduli. A characteristic feature of the pleural villi blood supply is the presence of capillary glomeruli with a vascular peduncle consisting of an arteriole and a venule. Four types of structure are revealed in the vascular peduncle consisting of an arteriole and a venule. Four types of structure are revealed in the vascular peduncle of the pleural villi. They were studied morphometrically. Correlation in the development of the villi microcirculatory bed and that of the vascular peduncle was stated. Participation of villous vessels in the regulation of fluid balance in the pleural cavity was discussed.

[Changes in leukocyte lysosomal acid and alkaline phosphatase activity in acute surgical diseases of the abdominal cavity organs]. / Izmeneniia aktivnosti kisloi i shchelochnoi fosfataz lizosom leikotsitov pri nekotorykh ostrykh khirurgicheskikh zabolevaniiakh organovbriushnoi polosti.

To discriminate initial stages of an inflammation from its destructive forms, the authors studied the leucocyte lysosome activity at different stages of inflammatory processes in abdominal organs. 90 patients and 30 practically healthy individuals were examined. The indices of acid and base phosphotase activity were found to rise together with the progress of an inflammatory process. A nomogram, permitting to determine with a rather high precision the stage and direction of the process, was made up on the grounds of the established reguliarity after the mathematical procession of the obtained figure data.

[Structure and function of the microcirculatory bed in the preserved heart]. / Stroenie i funktsiia mikrotsirkuliatornogo rusla konservirovannogo serdtsa

The morphological analysis of the state of the heart during hypertermal perfusion with different conservants reveals clear dependence of the microcirculation and the activity of the heart upon the type of the conservant. Perfusion with a salt solution and hemodilution is accompanied by pronounced disorders in microcirculation and unsatisfactory parameters of the cardiac activity. Conservation with cryoprecipitated plasma is characterized by comparatively less microcirculatory disorders, but fails to give a reliable safety of the heart. When using medium 199, changes in microcirculation were found to be minimal and parameters of cardiac activity were satisfactory. In the complex of non-specific changes in microcirculatory vessels the maximum structural lability was revealed in blood capillaries and vessels of the postcapillary-venular link.
