[The informativeness of indices of the heart rate variability for the identification of the adverse effects of environmental factors on the health of adolescent girls].

There was performed an investigation of informativeness of indices of the heart rate variability at rest and during orthostatic testing in the adolescent girls residing in the industrial town and in the village. The influence of unfa- vorable environmental factors was established to be reflected by the indices of the spectral analysis and cardioin- tervalography. In urban girls there was noted the marked increase of the centralization of heart rhythm control on the background of the increased activity of the sympathetic compartment and the reduction of the influence of the parasympathetic compartment of the autonomous nervous system on the sinus node.

[Features of psychophysiological status in adolescents with different intensity of sporting hours].

The experimental study of psychophysiological parameters of the central nervous system (CNS) has been performed in the adolescents who combine the learning-educational and sporting activities. The differences in psychophysiological indices in dependence on the intensity level of sporting loads have been revealed in the trained and non-trained adolescents in the presence of similar genetically determined abilities which may be determined by the force of the nervous system. The psychophysiological profile of.

[The specific features of microbiocenoses in children living under conditions of anthropogenic pressing].

The specific features of enteric and nasopharyngeal microbiocenoses and the species composition of bifidobacteria have been studied in children living in the industrial towns of the Irkutsk Region under the existing anthropogenic load. Ambient air pollution is characterized and a presumptive human health risk assessed.

[Ecologic and social problems of reproductivity in the Irkutsk region].

The study covered quantitative and structural features, changes in functional parameters of female reproductive system, in disorders of pregnancy, childbed and newborns in Irkutsk region. The authors demonstrated role and relationships of some regional factors--natural, ecologic and technogenic, occupational and industrial, social and economic--in formation of reproductivity, disorders during 1980-1990s.

[Quality of clinical diagnosis in infants under one year of age according to autopsy data].

An analysis of quality of clinical diagnosis of causes of death in infants (under 1 year of life) has been performed basing on the records of 1130 autopsies made in 1981-1998. The diagnosis accuracy, sensitivity, specificity and other quality characteristics have been assessed. The highest accuracy of clinical diagnosis has been found in respect of malformations, fetal hypoxia and natal asphyxia (0.
