Abstract
The problem of asymmetry is one of the fundamental in modern biology, theoretical and clinical medicine, it has deep evolutionary roots. Analysis of literature suggests that the coverage of various aspects of morpho-functional asymmetry of the kidneys to this time is not always unambiguous, and sometimes controversial. The purpose of the work is to establish manifestations of asymmetry of entering into regression models of sonographic sizes of kidneys anthropometric and somatotypological parameters of a body in practically healthy women and men of different somatotypes. Within the framework of the agreement on scientific cooperation from the database of the research center of the National Pirogov Memorial Medical University, Vinnytsya taken the primary sonographic parameters, anthropometric and somatotypological indicators of 121 practically healthy women and 97 practically healthy men of the first mature age (correspondingly, of the age from 21 to 35 and from 22 to 35 years old) who in the third generation live on the territory of Podillia region of Ukraine. For the construction of regression models of individual sonographic sizes of the kidneys, depending on the peculiarities of anthropo-somatotypological parameters of the body, the license package “Statistica 6.1” was used. To analyze the asymmetry of entering into regression models of sonographic sizes of anthropo-somatotypological indicators, all constructed reliable models, but not only models with a determination coefficient of greater than 0.6, were taken into account. Also, in the analysis, anthropometric and somatotypological indicators refer either to highly genetically determined (longitudinal body sizes, cephalometric indexes, width of distal epiphyses of long tubular limb bones, trunk diameters, pelvic sizes, ectomorphic component of somatotype, bone component of body weight) or to low genetically determined (mass, body surface area, body dimensions thickness of skin fat folds, endomorphic and mesomorphic components of the somatotype, muscle and fat components of the body mass). In men of various somatotypes, when analyzing the asymmetry of entering the models of sonographic sizes of the anthropometric and somatotypological indicators of kidneys, it has been established: in the mesomorphic somatotype representatives - 84.1% (among which 50.0% belong to highly genetically determined indices), in the representatives of the ecto-mesomorphic somatotype - 86.0% (among which 46.5% belong to highly genetically determined indicators), in the representatives of the endo-mesomorphic somatotype - 88.1% (among which 51.4% belong to a highly genetically determined indices). In women of various somatotypes, when analyzing the asymmetry of entering the models of sonographic sizes of the anthropometric and somatotypological indicators of kidneys, it was established:), in the representatives of the mesomorphic somatotype - 82.0% (among which 51.2% belong to highly genetically determined indices), in the representatives of the ectomorphic somatotype – 89.0% (among which 58.0% belong to highly genetically determined indicators), in the representatives of the endo-mesomorphic somatotype - 83.3% (among which 50.0% belong to highly genetically determined indicators), in the representatives of middle intermediate somatotype - 82.5% (among which 56.5% belong to highly genetically determined indicators).
Highlights
The problem of asymmetry is one of the fundamental in modern biology, theoretical and clinical medicine, it has deep evolutionary roots
The possibility of using the asymmetry of kidney sizes as a characteristic and criterion of morphophysiological characteristics of populations is taken into consideration, which records the increase of the level of both directed and non-directed asymmetry [41, 42]
If in most individuals in the population there is a predominance of any size on the one hand [41], they refer to the directed asymmetry of organisms and paired organs
Summary
The problem of asymmetry is one of the fundamental in modern biology, theoretical and clinical medicine, it has deep evolutionary roots. Paired organs practically are not strictly symmetrical: there are differences in mass, linear, volumetric dimensions, structure and functions. The fluctuating asymmetry is a non-directional oscillation of paired dimensions, when in different representatives of one population have some signs larger from the left, and in others - from the right side of the body. The increase in the degree of fluctuating asymmetry is related due to the negative influence of exogenous factors on the development of the organism The severity of this type of asymmetry depends on the type, intensity and duration of adverse factors on the one hand, and on the ability of the body to withstand adverse effects to stabilize the development process, regardless of the external effect [20, 41]. The asymmetry of the size of the kidneys may be related to the size of the liver, which impedes the vertical growth of the right kidney to the level achieved by the left kidney [24]
