[Species composition of anaerobic microflora in parodontal pocket depending upon disease stage].

With the help of polymerase chain reaction (PCR) the dynamic of species composition of anaerobic microflora in cases of generalized parodontitis was established. It was detected that disease severity increase was followed by the increase of the number of anaerobic microflora species in parodontal pocket; at that it was impossible to connect the presence of some determined type of microorganism with the inflammatory parodontal process intensity. It was shown that proteins fimbrilin and gingipain were not the only parodontitis pathogenic factors although the first one (fimbrilin) could be connected with aggressive disease flow.

[Microflora dynamics in purulent skin wound in rats after ozonized perftorane applications].

In 30 Wistar rats divided in 3 groups with 10 rats in each skin defects were reproduced under anaesthesia and wound surface was fixed with the help of plastic rings. The wounds were contaminated with microbe dredge consisting of St. aureus, Ps.

Longitudinal genetic analysis of childhood IQ in 6- and 7-year-old Russian twins.

Using a longitudinal twin study of Moscow children, we have studied the development of psychometric intelligence during the transition from preschool (age 6) to school (age 7). Children were tested using the Wechsler Intelligence Scale for Children (WISC). Simplex models were applied to explore the relationship of different sources of phenotypic variance.

[Effect of genotype on the relationship between parameters of intelligence and cognitive style].

The roles of genetic and environmental factors in regulating parameters of intelligence and cognitive style were studied. Monozygotic and dizygotic twins were tested three times, at the ages of 6, 7, and 10 years. The Wechsler Intelligence Test, Embedded Figures Test, and Matched Figures Fitting Test were used.
