[Significance of considering hemoglobin derivatives and acid-base balance in the evaluation of the blood oxygen-transport system].

Factor analysis was used to study the pattern of relationships of a number of hematological parameters in clinically healthy young subjects and in patients with moderate anemia. The level of total hemoglobin and the concentration of red blood cells were ascertained to control blood oxygen-transporting function in not full measure and these might be referred to as basic characteristics only conventionally. To clarify the picture, these criteria should be supplemented by the information on other parameters.

[Risk factors of atherosclerosis in young people].

Factor analysis was used to study an association of risk factors of atherosclerosis (AS) in student during their study. These factors were shown to be rather evident just at the age of 17-22 years. The correlation matrixes in male and female students are described by a mixed number of factors and the factors differ themselves in the internal structure, magnitude, and correlation signs.

[Parameters of the distribution of blood cell volumes in chronic renal failure].

Factor analysis was used to study the relationships of the count of red blood cells, lymphocytes, neutrophils, and platelets in health and chronic renal failure (CHF). The concentrations of cells, their average volume, and the indices of its distribution volume parameters (standard deviation, asymmetry coefficient, and excess gradient) were determined. It has been shown that the values of these characteristics are closely coordinated and the factor structure of fixed correlations depends on the state of an organism, has gender specific features, and produces a clear morphofunctional portrait of each of the stages of the course of CHF.

[Time course of changes in the volume of blood cells in pregnancy].

The time course of changes in the parameters of the corpuscular volume of red blood cells, lymphocytes, neutrophils, and platelets was studied during uncomplicated pregnancy. It was ascertained that in pregnancy, the mean volume of red and white blood cells and that of platelets remained steady-state. Adaptive changes were observed in the fine structure of blood cells of all types.
