[The dynamics of coheren links in persons with different ability to recognise speech emotional expessions].

The coherency characteristics of the brain electrical activity were studied in two groups of subjects: 1) with high and 2) low indexes of "emotional ear" (an ability to successfully recognize emotions in the speech). Comparison of the coherency links between two groups of subjects permitted the authors to make a conclusion that the persons of the first group had a much lower coherency level, especially in the alpha- and gamma-rhythms. The subjects of the second group were characterized by the opposite tendency: an increase in coherent links on the majority of frequency bands.

[Renin-angiotensin and kinin-bradykinin genes polymorphism effects on permanent arterial hypertension in children].

New methods are required for more objective estimation of the polymorphic genes contribution in multifactorial diseases. We suggest new approach based on the calculation of relative "score" as a sum of relevant genetic polymorphisms studied. Application of suggested approach is evaluated in analysis of the genes REN (19-83G>A), AGT (M235T), ACE (I/D), AGTR1 (1166A>C), AGTR2 (3123C>A), BKR2 (-58T>C and I/D) in children with arterial hypertension.

[DNA polymorphism in the region of APOB100, APOCIII, APOE, and angiotensin-converting enzyme genes and indicators of the lipid spectrum in children and adolescents in St. Petersburg].

Polymorphisms of 3 apolipoprotein genes Xba I apoB, Sstl apoCIII, and apoE and the insertion-deletion polymorphism of the angiotensin-converting enzyme gene (I/D ACE) and lipid levels were studied in a random sample of 403 children and adolescents aged 6 to 18 years living in St. Petersburg. The children were divided in 4 age groups with consideration for the relative body weight index: group 1.
