[The history of the Kazan School of Therapists (on the occasion of the 200th anniversary of the Kazan State Medical University)].

The history of the Kazan School of Therapists numbers two centuries of scientific achievements and discoveries. German Professors F.H.

[Study of nasal and tonsillar mucosal microbiocenoses as one of the health indices].

The qualitative and quantitative compositions of nasal and tonsillar mucosal biocenoses were studied in healthy individuals and patients with chronic tonsillitis as an ecological criterion for assessing the stability of biocenosis and human health. The qualitative composition of tonsillar mucosal biocenosis turned out to be steady-state both in health and disease. The human nasal mucosa showed itself as an indicator system.

[Study of renal functional reserve in healthy individuals using dopamine].

The effect of dopamine intravenously injected in doses of 1 and 3 microg/kg/min on renal hemodynamics was studied in healthy individuals; the test followed a water load of 5 ml/kg. Glomerular infiltration rate and renal reserve were calculated from the blood and urine Cr concentration. The load of dopamine was found to be comparable with that of protein and amino acids.

[The role of persistence and virulence factors in microecological changes in a humans].

The patterns of persistence and virulence factors expression in the representatives of human microbial biocenosis depends on a complex of the environmental conditions: influence of microbes-symbionts, biotope peculiarities, properties of microorganisms located within eukaryotes. Interactions of symbionts in pairs "indigen-indigen" isolated from mucous membrane of tonsils in healthy persons, did not lead to changes in expression of pathogenic properties. Interinfluence in pairs "pathogen-indigen" and "indigen-indigen", isolated from patients with chronic tonsilitis were accompanied by an increase of anti-lysozyme, hemolytic and lecithovitellase activities.

[Microflora of the mucous membrane of human tonsils in the normal state and in pathology].

A total of 50 healthy persons and 50 chronic tonsillitis patients were examined with the use of the bacteriological method. The microflora of tonsillar mucous membrane was represented by 8 genera of facultative anaerobic microorganisms. In the biocenosis of the tonsillar mucosa of the healthy subjects the occurrence of Streptococcus was 1.
