T2255C polymorphism (rs2359612) of vitamin K-epoxidoreductase (VKORC1) gene in 118 patients with acute coronary syndrome (ACS) and in 234 healthy people was determined. It was shown that in patients with ACS interrelation of main homozygotes, heterozygotes and minor homozygotes were 27.1 %, 41.5 % and 31.4 % (in control – 37.2 %, 42.7 %, 20.1 %. P = 0,038 by χ2-test). Thus, there is an association between T2255C polymorphism and the development of ACS: the risk of ACS in homozygotes for the minor allele (C/C) is 2.1 times higher than in homozygous for the major allele.

The aim of the study was to research the cardiovascular system functional state in healthy teenagers as they had done certain exercise tests. We examined 68 children by the Doppler echocardiography method. The inadequate response of cardiovascular system had 25 % of teenagers. The main factors that had led to the state were: basic high blood pressure and general low level of physical activities. The systolic function of the heart enhanced during the lower dynamics of diastolic function.

Peripheral neuropathy is a clinical syndrome that develops as a result of various aetiological factors impacting peripheral nerves. It is distinguished by heterogeneous pathogenetic mechanisms. Polioneuropathies occupy the second place in the structure of diseases of the peripheral nerve system after vertebraginic pathology, but greatly exceed it in the complicated clinical manifestations and crippling consequences. Important role is played by the vessel factors of neuropathy development, which are connected with the involvement of vasa nervorum and combine a big group of diseases. To detect the pathological changes in the microcirculatory blood stream of peripheral nerves advanced pathohistological research of its components on various levels is needed; this research is carried out by pathologists with the use of the whole complex of techniques aimed at the elective detection of various elements of vessel wall. The issue of protocol development enabling the complex multi-factor analysis of great amounts of data is therefore in question. The objective of our research is the development of the systematic list of pathohistological changes in the microcirculatory blood stream of the peripheral nerve. The research protocol for the description of pathohistological changes of some components of the microcirculatory stream of the peripheral nerve was developed based on referenced data and our own observation experience. The systematic list of pathohistological changes was verified in the examination of 220 n. tibialis of diabetes patients and in the control group. The use of the suggested research protocol for the description of pathomorphological changes in vessels will enable objective diagnosis and correct interpretation of the obtained data. The prospects of our research lie in the development of the computer-based morphometric analysis of the haemocirculatory blood stream of peripheral nerves.

The article is devoted to evaluate dynamics of planimetric indexes of burns. I took rats of different age and applied innovative chitosan membranes on the burns. I modeled IIIb burns on the rats from both experimental and control groups; I used chitosan-based coatings for topical treatment. Planimetric analyses of the affected areas were performed by the “SEO Image lab 2.0” program (Sumy, Ukraine) considering the total affected area (sm2); the relative areas of dead tissue, granulation tissue and epithelization (%). I measured them on 1st, 3rd, 7th, 14th and 21st days after the burn modelling. These days show key phases of skin healing. I determined the rate of burn healing according to certain criteria: average rate of affected area reduction (sm2) per day; reduction in burn area (%) per day. Natural chitosan coatings prevented from repeated infections protecting the burn areas from exogenous factors. Besides, it was applied easily on the affected areas to protect newly formed epithelium. Healing process speeded up during the inflammatory phase as both burn cleaning and granulation tissue formation enhanced. Moreover, gripping of the burn edges occurred during the proliferation and remodeling phases. Due to these results I may claim that period of healing process with rate of epithelization has decreased by 1.5 day.

The influence of quantitative and qualitative composition of intestinal microflora on the state of mineral metabolism and the immune system was study in the 128 children with asthma. The correlation between the number of representatives of the intestinal microbiota, bioelements and indicators of immune status were studied. The dependence of immune parameters, micronutrient content and quality of intestinal microflora detected in children with asthma that manifested significant imbalance of immune and microelement’s homeostasis. The results give reason to consider overgrowth in school age children with asthma as one of the factors that support secondary immunodeficiency, impaired microelement’s metabolism. The reducing of the number of lacto-and bifidobacterias, E. coli colonies and growth of opportunistic microorganisms, staphylococci and fungi have a significant impact on changes in the immune system and the microelement’s composition, supports allergic inflammation in the body of the child, even in remission, which is important and promising in terms of finding new ways of optimal treatment of childhood asthma.

The article examines the features of the balance of pro-and anti-inflammatory cytokines in full-term infants with impaired renal function due to asphyxia at birth. The study involved 252 full-term newborns with signs of kidney damage: 102 children who had severe asphyxia and 150 children with moderate asphyxia. The level of interleukin -1β, interleukin -6, tumor necrosis factor α and interleukin -10 in serum determined by on the 1–2nd , 7–8th and 25–30th days of life by ELISA. Interleukin-6 is the most informative cytokine; its level increased in the first days of life in case of impaired renal function and depended on the severity of asphyxia. Determination of interleukin-1β in serum is necessary for retrospective assess severity of the asphyxia in newborns at the end of neonatal period. Serum level of interleukin-10 is closely correlated with the levels of proinflammatory cytokines in the first days of life in children with impaired renal function due to asphyxia. Character of correlation depends on the prevalence of regulatory or suppressive processes.

Advances in antiretroviral therapy (ART) have drastically improved the quality of life for people with HIV infection. However, complex therapy leads to suppression of plasma viral loads in HIV-1 patients. Despite this therapy, a low level of viremia in plasma can be frequently detected by sensitive clinical assays. Additionally, many patients experience transient episodes of viremia above the detection limit, even if they have been undergoing highly suppressive therapy for many years. Failure of HAART to eradicate HIV associates with the existence of persistent infection in certain cellular and anatomical reservoirs. The latent reservoir considers being the major hurdle in HIV eradication. In addition, deep suppression of viral replication does not restore the immune status fully that was effected by HIV infection. This is a consequence of chronic immune activation, caused by the increased permeability of the intestinal barrier and translocation of bacteria and products of their decay. Progress in the infection eradication requires new approaches in the fight against latency and immunodeficiency.
