Blood biochemical parameters of 17-20 years-old girls of different constitutional types

The article is devoted to the analysis of blood biochemical indicators of girls belonging to different constitutional types. It has been identified that the level of albumin and triglycerides was significantly lower, and the concentration of urea was higher in blood plasma of girls with asthenic body type in comparison with girls of other constitutional types. The studies revealed that girls of normosthenic constitution type had the lowered level of total and direct bilirubin in comparison with other types. Lower concentration of calcium, phosphorus, and α-cholesterol occurred in girls with hypersthenic constitution type, whereas the level of direct bilirubin, alkaline phosphatase and triglycerides was significantly higher in comparison with other types. The concentration of glucose, total protein, creatinine did not differ between girls of different constitutional groups. The correlation analysis of biochemical indicators showed that a range of parameters of protein, lipid, carbohydrate, mineral, fermental and pigmentary metabolism had reliable interrelations between themselves. The representatives of the asthenic type demonstrated more apparent system of correlation ties between the fermental and lipid balance. Significant correlations occurred between parameters of protein and fermental metabolism in females with a normosthenic body type, and between fermental, protein and mineral metabolic parameters in females with a hypersthenic type. The analysis of structure and the number of correlation ties in girls with the asthenic and the normosthenic constitutional types allows to assume high plasticity of metabolic processes which determines good performance of adaptive mechanisms against various external factors, whereas a large number of tight correlations occurred in girls of hypersthenic type indicates their high resistance to various factors and lower level of plasticity to changing conditions. It is emphasized that the type of constitution is a "phenotypical expression of a gene complex" that is caused by specific correlations between biochemical indicators in females with different types of body constitution. Probably, it reflects the constitutional determinant of metabolic processes determining an individual biochemical profile of a person. The obtained data have prognostic value for studying biological identity that is important in interpreting blood analysis results of both healthу and sick people.
