[The impact of disbalance of regulatory cytokines and osteocalcin on osteogenesis in children with congenital cleft lip and palate in postnatal ontogenesis]. / Vliianie disbalansa reguliatornykh tsitokinov i osteokal'tsina na osteogenez u detei s vrozhdennoi rasshchelinoi guby i neba v postnatal'nom ontogeneze.

The aim of the work was a comprehensive assessment of the system of cytokines and peripheral blood osteocalcin with the establishment of features of their interconnections in children with congenital cleft lip and palate (CCLP) in comparison with the corresponding controls at different age periods. In the peripheral blood of 80 children (0-12 months, 1-3 years, 4-9 years, 10-15 years) with osteocalcin and IL17, IL4, congenital cleft lip and palate and age-appropriate control of healthy individuals (40 people) IL6, IL1ß, IFNγ by enzyme immunoassay. An analysis of the data obtained with CCLP revealed significant differences in the dynamics of the relationship between pro-inflammatory (IL1ß, IL6, IL17), regulatory (IFNγ), anti-inflammatory (IL4) cytokines and osteocalcin compared with controls. The patterns of changes and effects of IL17, IFNγ, IL4 and osteocalcin in healthy children and in children with congenital cleft lip and palate in postnatal ontogenesis were established. Cytokine dysregulation of immunosteogenesis in CCLP, leading to a significant deficit of osteocalcin in the first year of life due to an imbalance of the cytokine profile: discordant IL17, IFNγ and IL4 were detected. Thus, the data obtained are undoubtedly important in the future for developing new strategies for targeted therapy aimed at normalizing osteocalcin levels at different age periods in children with congenital cleft lip and palate.

[COMBINED IMMUNOTHERAPY OF RECONDITIONAL CHRONIC NON-SPECIFIC VULVOVAGINITIS IN IMMUNOCOMPROMISED GIRLS].

Nonspecific chronic vulvovaginitis (CNV) is often a clinical indicator of immune deficiency, especially in young girls. The established violations of the functioning of various parts of the immune system (IS) in this pathology dictate the need to include in the complex of immunomodulatory therapy. The developed program of combined immunotherapy for immunocompromised girls allows to reduce the severity and duration of exacerbation of CNV, their frequency against the background of a significant reduction in the incidence of ARVI. Positive clinical effects were observed against the background of the restoration of the functioning of the IS. A protective effect was obtained (observation in a catamnesis for 1 year) - the duration of a clinically safe period increased from 6 to 11-11,5 months per year.

[DYNAMICS OF OCCURRENCE AND REGRESSION OF NEUTROPHIL EXTRACELLULAR TRAPS IN THE EXPERIMENTAL MODEL OF THE WOUND INFECTIOUS-INFLAMMATORY PROCESS].

The dynamics of the appearance and regression of neutrophilic extracellular traps (NETs) in the experimental model of the wound infectious-inflammatory process that was caused by infection of open wounds by microbes surrounding environment, was studied. It was established that on the second day from the start of the experiment a significant number of mature neutrophilic granulocytes show the ability to form NEТs. The number of NETs was reached its maximum by the 2th and 4th days from the beginning of the experiment, that was associated with maximum occurrence of symptoms of inflammation in the wound. The regression of the wound inflammatory process was associated with decreasing of the number of NETs to 7th day and the complete disappearance of NETs to 14th day of the experiment, which coincided with the healing of wounds.
