[Significance of the determination of gonadotropic pituitary hormones in different types of autonomic vascular dystonia]. / Znachenie issledovaniia gonadotropnykh gormonov gipofiza i éstradiola pri razlichnykh tipakh vegetososudistoi distonii.

Measurements were made of the content of gonadotropic pituitary hormones (prolactin/PRL), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and estradiol in 151 children aged 11 to 15 years. Of these, there were 58 healthy children (24 boys and 34 girls), 51 children (25 boys and 26 girls) with vegetovascular dystonia (VVD) of the vagotonic type and 42 children (22 boys and 20 girls) with VVD of the sympathotonic type. It has been established that in VVD children, alterations in the hypothalamus-pituitary-gonadal system agreed with the general biological reactions of the body, while deviations in the LH and FSH levels as well as in estradiol got stabilized by 13 to 15 years. A positive correlation has been revealed between the high blood PRL level and the high tone of the sympathetic nervous system. In view of this fact the blood PRL content can serve an early diagnostic test for recognizing hypersympathicotonia in VVD children.

[Integral electrocardiotopography in children and its diagnostic value]. / Integral'naia élektrokardiotopografiia u detei i ee diagnosticheskoe znachenie.

Biopotentials of the heart were studied in 120 normal children aged 3 to 14 years by means of integral electrocardiotopography. The data obtained made it possible to reveal a number of common mechanisms characteristic of the child's body: the presence of pathway zones, the multipolar type of potential distribution, high degree of minimal potentials according to the electropositivity and electronegativity charts, high degree of the gradient according to the electropositivity charts, and the presence of the zones with dipole span. The results of the studies may be regarded as new perspective approaches to further improvement of the diagnosis of cardiovascular diseases in children with the aid of integral electrocardiotopography.
