[Effect of anthropotechnogenic chemical factors on formation of somatotypes in children and adolescents of school age]. / Formirovanie somatotipov u detei i podrostkov shkol'nogo vozrasta pod vliianiem antropotekhnogennykh khimicheskikh faktorov.

This research was done to study the dynamics of a process of constitutional types formation in 163 schoolboys and 181 schoolgirls, who live and study in various regions of the city of Ivanovo which are characterized by a different degree of environmental pollution with heavy metal salts and lead in particular. To define the constitutional types, the method of V.G. Shtefko and A.D. Ostrovsky (1929) was used. It was demonstrated that environmental pollution with heavy metal salts, the absorbed dose of which 3 times exceeded the maximum permissible dose, lead to the delay of somatotype differentiation in children and adolescents, which was more pronounced in schoolboys than in schoolgirls.

[Evaluation of the effectiveness of organ-preserving solutions]. / Otsenka éffektivnosti organosokhraniaiushchikh rastvorov.

In the experiments performed on 61 dogs dynamics of changes of morphometrical parameters of mitochondria of brush-border and cuboid cells have been studied at conservation of the kidneys for 120 h in solutions of intracellular type. Stages of structural reorganization of the mitochondria have been determined depending on duration of conservation and the solution composition. A morphometrical index of viability (Im) has been worked out, correlated with survivability of the transplant and the recipient. In every specific case it allows to estimate quantitatively whether the conserved kidney is suitable for transplantation. At Im less than 50% from the control level, the kidney is not viable, at 50% less than or equal to Im less than or equal to 60%--it is conditionally suitable for transplantation, at Im greater than 60%--it is viable. The index elaborated is practically used for a comparative estimation of the protective action of the four organ-preserving solutions of the intracellular type. The morphometrical index of viability of the conserved kidneys can be used in experimental transplantology for approbation of new solutions before their application in clinical practice.

[Ionometric method of assessing the viability of a preserved kidney]. / Ionometricheskii sposob otsenki zhiznesposobnosti konservirovannoi pochki.

It has been shown that the process of normalization of the ionic content of kidneys preserved during 6--72 hours with solutions of the "intracellular" type, is most intensive within the first 15 minutes after transplantation. At that time characteristic changes in the content of electrolyte were found in the blood outflowing from the kidney depending on the time of preservation. It enabled the authors to propose a simple and reliable ionometric method for the assessment of the kidney viability.
