ABSTRACT
The behavior of the state vector of human cardio-vascular system in different age groups according to methods of theory of chaos-self-organization and methods of classical statistics was investigated. Observations were made on the indigenous people of North of the Russian Federation. Using methods of the theory of chaos-self-organization the differences in the parameters of quasi-attractors of the human state vector of cardio-vascular system of the people of Russian Federation North were shown. Comparison with the results obtained by classical statistics was made.

Using original direct methods of shaking-imprinting and rapid sampling of metaphase and prometaphase chromosomes, a cytogenetic analysis has been performed in 80 diagnostic chorionic villus samples (CVS) in the first trimester. Chromosomal disorders were identified in 6 (7.5%) fetuses: Down's syndrome in 4, monosomy 18 in 1, and a short-arm deletion of chromosome 18 in 1. These pregnancies were terminated. The paper offers opportunities for reducing risks of transcervical CVS and widely applying first-trimester chromosomal analysis in a program of mass screening for chromosomal and genetic diseases.
