[Medicosocial assessment of orthodontic care to the population of the Riazan Region].

The dental health of the adult population of Ryazan and the rural areas under study is characterized by the high prevalence of various abnormalities. There was the highest level of orthodontic diseases among the dwellers of districts: in Ryazan, pathology was 2.2 cases per 1 patient versus 1.

[Oral cavity microflora in patients with non-specific ulcerative colitis and Crohn's disease].

Results of study of microecological disorders in oral cavity of patients with non-specific ulcerative colitis (NSUC) and Crohn's disease (CD) and control subjects (patients with hypertension). Condition of mucosa was assessed on the basis of morphological data and electrophoretic mobility of cell nuclei, whereas structure of microbiocenosis and metabolic activity of microflora--on the basis of saliva bacterial culture and contents and profile of volatile fat acids in it. Detection rate of negative charge of the cell nuclei (decrease of functional activity of epithelium) was significantly higher in patients with NSUC and CD (66.

[Impairment of microbial environment of the colon in angiogenic cochleo-vestibulopathies and lipid distress syndrome].

We studied structural and metabolic microbiocenosis of the colon in angiogenic cochleovestibulopathies and lipid distress-syndrome by gas-liquid chromatography estimation of the level and spectra of volatile fatty acids, secretory immunoglobulin A, coprological test in 47 patients. As a result, disbiotic affection of the intestine in lipid distress-syndrome is characterized, ways of microflora normalization are shown.

[Susceptibility of beta-hemolytic streptococci to antibiotics and alternative drugs].

Antibiotic susceptibility of the circulating beta-hemolytic streptococci of serogroups A, B, C and G isolated from healthy and sick children and adults within 1987-1996 (more than 900 cultures) was studied. It was shown that the MICs of betalactam antibiotics did not change (within the susceptibility levels) with respect to the serogroup A, C and G streptococci. The number of the strains resistant to erythromycin and lincomycin increased the same as the frequency of the strains simultaneously resistant to chloramphenicol, tetracycline and gentamicin.

[The hydrophobicity of Streptococcus pyogenes as a possible marker of its virulence].

The hydrophobicity of 366 S. pyogenes cultures isolated from the pharynx of tonsillitis and scarlet fever patients and healthy children, as well as museum strain of type M29, was studied. The study revealed that the hydrophobicity of cultures isolated from scarlet fever patients exceeded that of cultures isolated from healthy carriers and tonsillitis patients.
