In the following article we are going to provide the results of research on uterus’ structure in case of fetuses with a gestational term of 21-28 weeks from mothers, whose pregnancy was complicated by PE of different severity stage (15 cases) comparing to one in case of fetuses from mothers with a physiological pregnancy (15 cases). All fetuses have died intranatally as a result of an acute disorder in uterine-placental and uterine-fetal circulation. The research methods: macroscopic, organometric, histological, immunohistochemical, morphometric and statictical. By applying an organometric method we have revealed a probable decrease of indexes of weight, length and thickness of the uterine’ wall in case of fetuses from mothers with PE comparing to ones in case of fetuses from healthy mothers. The observative histological research had not revealed any significant changes in the strucutre of the organs’ wall in case of fetuses from the study groups. Thus, all organs were represented by mucous, muscular and serous membranes with a clear boundary between them. The comparative morphometric research had revealed the following features of the uterus’ wall structure in case of fetuses from mothers with PE. The indexes of thickness of all structural components of the organ’s wall were clearly decreased comparing to ones in case of fetuses from mothers with a physiological pregnancy. In the uterine endometrium of fetuses from mothers with PE of moderate stage of severity the features of proliferative (hormonal) activity are taking place, however, in the meanwhile, in case of organs of fetuses from mothers with PE of severe stage of severity we could notice a probable decrease of glands’ number as well as a lack of a proliferative activity in them (hypoplastic changes). By applying immunohistochemical method with using MCAT to CD 95 we have disclosed a probable increase of an apoptotic index in organs of fetuses from mothers with a complicated pregnancy towards one in case of fetuses from healthy mothers. Among the specific features of the uterine myometrium strucutre in case of fetuses from mothers with PE we could name the following ones: decrease of the vascular component percentage as well as increase growth of the connective tissue. Moreover, the structure of the connective tissue is represented mostly by the collagen of the III type, while, in case of organs of fetuses from healthy mothers the collagen of the I type prevails. In walls of the vessels of arterial type in case of uterus of fetuses from mothers with PE we could notice an increased glow of the collagen of the III type as well as a probable decrease of glow in case of collagen of the IV type. However, in case of organs’ vessels of fetuses from healthy mothers we could notice an increse of glow of the collagen of the IV type. There is a fact, which attracts an attention to it. Namely, all aforementioned changes in the uterine wall in case of fetuses from mothers with PE are minimally manifested, when the mild course of disease took place, and was maximally manifested in case of severe one. All changes in the uterus in case of fetuses from mothers with PE of different stage of severity, that were postulated above, could contribute to formation of glanduar hyperplasia, endometrial polyps, precancerous diseases as well as endometrial cancer in the subsequent ontogenesis, as well as it could lead to impaired pregnancy and infertility. All aforementioned changes in organs of fetuses from mothers, whose pregnancy was complicated by PE of different stage of severity, were connected with changes in the vascular bed of the mother-placenta-fetus system as well as with endocrine disorders, that take place in case of this pathology, in the organism of pregnant woman.

The relevance of the following article is prescribed by the growing number of perinatal mortality and morbidity among newborns due to the mother’s chronic infection of the lower genital tract (HILGT). It is commonly known, that HILGT contributes to the delay of the fetal development likewise is often manifested by the violation of internal organs and systems implementation. One of the most acute topic is the the fetus’ reproductive system in ther early gestation terms. However, the immunohistochemical features of the fetuses’ uterus structure with the gestational term of 21-28 weeks from mothers with HILGT on the current stage of the medical science develpment have not been described yet. The aim of the current research is to identify immunohistochemical features of the fetuses’ uterus structure with the term of gestation of 21-28 weeks from mothers, whose pregnancy is complicated by HILGT. Material of the research: 25 fetuses from mothers, whose course of pregnancy was physiological (group of comparison) as well as 25 fetuses from mothers, whose pregnancy was complicated by HILGT (main group). All fetuses had died intranatally, as a result of acute uterine placental and placental-fetal circulation. Research methods: organometric, histological, immunohistochemical, morphometric, statistical. The research results and their discussion: the organometric parameters of the fetuses’ uterus from the main group were clearily decreased in comparison to such parameters in case of the group of comparison. The decrease of the parameter of the uterine wall thickness of fetuses from mothers with the complicated pregnancy prescribes thinning of the main structural components. Namely: endometrium, myometrium and perimetrium. In case of endometrium of fetuses’ uterus a decrease of number of glands and the lack of their functional activity was noticed. It characterizes this layer as structurally immature.At the same time, in case of fetal organs of fetuses from mothers with complicated pregnancies, we could notice an increase in the number of apoptotically altered cells. Comparing to the structure of layers of uterine walls in case of fetuses from mothers with physiological pregnancy, in the uterus of fetuses from mothers with complicated pregnancy our attention is attracted by a massive growth of the connective tissue. In the myometrium it contributes to the disruption of the muscle fibers strusture likewise to its absence in some areas. By the immunohistochemical method it was possible to reveal a prevalence of the collagen of the III type in the structure of connective tissue likewise in the walls of blood vessels. It is connected primarily with disruption of the collagen’ maturation. The vascular component of the uterine wall in case of fetuses from mothers with HILGT differs from ones in case of fetuses from mothers with physiological pregnancy. This difference is grounded on the increase of endothelin-producing activity by vessels of both arterial and venous types. By processing preparations by monoclonal antibodies to estrogen, it has been postulated, that the intensity of the reaction as well as number of cells in the fetuses’ organs of the main group are clearily decreased comparing to ones in cases of fetuses from the group of comparison. The disorders of the fetuses’ uterus in case of fetuses from mothers with HILGT, that were provided in the current article, are prescribed by chronic hypoxia, endocrine disorders as well as influences of the infectious agents, that are taking place in case of such pathology. The characteristic features of the fetuses’ uterus structure in case of fetuses from mothers, whose pregnancy is complicated by HILGT, indicate gross violation in the organ’s implementation on the early stages of the fetal organogenesis, likewise they could be a leading link of pathogenesis of primary infertility’ development in the future ontogenesis.

The following article presents results of the complex research on postulation of immunohistochemical features of the ovaries’ structure in case of fetuses with a gestational term of 21-28 weeks from mothers with HILGT comparing to ones in case of fetuses from mothers with a physiological pregnancy. The materials of the research are: 25 fetuses from mothers with HILGT as well as 25 fetuses from mothers with physiological pregnancy. All fetuses had died antenatally and inranatally, as a result of violation of uteroplacental and umbilical-uterine circulation. Research methods: macroscopic, organometric, histological, immunohistochemical, morphometric, statistical. The organometric method revealed a clear decrease of main indexes of the fetuses’ ovaries from mothers with a complicated pregnancy comparing to ones in case of organs of fetuses from healthy mothers. Morphometric method revealed a clear decrease of a relative volume of cortical substance as well as a clear increase of a relative volume of brain substance in the gonads of fetuses from the main group; as well as it showed a clear decrease of an index of follicular tissue’ relative volume, likewise a clear increase of an index of interstitial component relative volume.The staining by picrofuxin by van Gieson method revealed a massive growth of the connective tissue in all strucutral components of organs of fetuses from mothers with HILGT relatively to gonads of fetuses from healthy mothers. Using of MCAT to main types of collagens allowed to reveal a violation of maturation of main types of collagens in the structure of connective tissue of fetal gonads in the main group. In the follicular component of the fetuses’ ovaries in the main group are appearing mature, cystic-artretic and growing forms of follicles. Immunohistochemical method revealed an increased number of an apoptotically altered eggs in the ovaries of fetuses from mothers with HILGT comparing to one in organs of fetuses from mothers with physiological pregnancy.  The peroxidase method revealed an increased endotheline-producing activity of the vascular component as arterial, like a venous type; likewise a clear decrease of the hormone-producing activity in the ovaries of fetuses from mothers with HILGT comparing to such indexes in fetal organs of fetuses from mothers with physiological pregnancy. The complex of changes in the ovaries of fetuses with a 21-28 weeks of gestational term, which was described, was formed under the influence of the chronic hypoxia, prolonged antigenic stimulation as well as hormonal violations in the mother-placenta-fetus system, which is a leading link of the infectious pathology’ pathogenesis. The aforementioned complex of the structural and functional changes in the ovaries of fetuses from mothers with HILGT in a gestational term of 21-28 weeks indicates violations in implementation and formation of the fetal gonads, as well as it could further lead to disorders of the germinal function in the female organism.

α-Fetoprotein (AFP) was successfully demonstrated in paraffin-embedded sections of human and rat fetal livers, by a multilayering immunohistochemical technique using the peroxidase-antiperoxidase system. Serial sections simultaneously subjected to immunofluorescence showed identical sites of localization in hepatocytic cytoplasm and sometimes in perivenous connective tissue. AFP-containing hepatocytes were located around efferent veins as well as randomly in the lobule. The immunoperoxidase technique has certain advantages over the immunofluorescence method which would justify the former's application in studies on the dynamics of AFP synthesis.

Oxidative stress seems to be involved in the path physiology of cardiovascular complications of chronic kidney disease (CKD). In this study, we determined the effect of different stages of CKD and substitutive therapies on oxidative stress. One hundred sixty-seven patients (age:44±06years; male/female: 76/91) with CKD were divided into 6 groups according to the National Kidney Foundation classification. Prooxidant status was assessed by assaying thiobarbituric acid reactive substances, hydroperoxides, and protein carbonyls. Antioxidant defence was performed by analysis of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, vitamin E, Iron, and bilirubin. TBARS and LPO were higher in HD patients compared to other groups (P<0.001), while protein carbonyls were more increased in PD patients. The antioxidant enzymes were declined already at severe stage of CKD and they were declined notably in HD patients (P<0.001). Similar observation was found for vitamin E, Fe, and bilirubin where we observed a significant decrease in the majority of study groups, especially in HD patients (P<0.001). The evolution of CKD was associated with elevated OS. HD accentuates lipid, while PD aggravates protein oxidation. However, the activity of antioxidant enzymes was altered by impaired renal function and by both dialysis treatments.

In the following article we are disclosing immunohistochemical features of the fallopian tubes’ structure in case of fetuses with a gestational term of 21-28 weeks. We have studied the structure of organs of 15 fetuses from mothers with a chronic infection of the lower genital tracts (HILGT) (the group of comparison) relatively to one in case of 15 fetuses from mothers with a physiological pregnancy (the main group). All fetuses had a gestational term of 21-28 weeks and had died intranatally as a result of an acute disorder of uterine-placental circulation. Methods of reearch: organometric, histological, immunohistochemical and statistical. The complex research allowed to reveal a probable decrease of the organometric data as well as indicators of thickness of the main structural components of the organs’ wall in case of fetuses from mothers of the group of comparison relatively to ones in case of fetuses from the main group. By applying histological method we had reveled a disorder in the strucuture of mucous and muscular membranes in the structure of organs of fetuses from mothers with a pathology of pregnancy, which is manifested by decreasing of number of folds, uneven thickness of the mucous membrane as well as disorder in formation of the muscular membrane’ layers. Immunohistochemical method has revealed an increase of apoptotically changed mucosal cells in the fallopian tubes of fetuses from mothers with HILGT. By applying MCAT to endotheline-1 we have revealed an increased glow of endithelial cells in vessels both of arterial and venous types in the strucuture of the organs’ wall in case of fetuses from the group of comparison. During the study on the endocrine activity of organs of fetuses from mothers with complicated pregnancy we have postulated a probable decrease of the cells’ glow’ intensity towards MCAT of progesterone. At the same time, there is also an inflammatory infiltration in the mucous membrane of the fallopian tubes’ wall. The aforementioned changes in the strucuture as well as in the functional activity of fetuses’ organs from mothers’ with HILGT are formed under the influence of chronic hypoxia and endocrine insufficiency of the feto-placental complex, which is taking place in case of this pathology. Histological and immunohistochemical features of the fallopian tubes’ structure in case of fetuses from mothers with complicated pregnancy are indicating a disorder in formation and maturing of the organ as well as they could lead to development of ectopic pregnancy and tubal infertility in the subsequent ontogenesis.

The objective of the work was to study modern clinical and anamnestic features of chronic lichenoid dermatoses. Materials and methods.Clinical and anamnestic examination of 100 patients with psoriasis and 80 patients with lichen planus (LP) was carried out. In both study groups, the majority were patients 51–60 years old, the minority – patients 31–40 years old. Among patients with psoriasis, men prevailed in all age groups, among patients with LP, men prevailed in the group of 20–30 years. Results. In the general gender structure, men prevailed in the group of patients with psoriasis, women prevailed in the group of patients with LP. Comparison of the anamnestic data regarding dermatoses revealed a chronic recurrent nature, characteristic of both psoriasis and lichen planus. According to the to the duration of the disease, among patients with psoriasis, the majority were patients with a long course of more than 10 years, among patients with LP – patients with a history of less than 1 year. In the group of patients with psoriasis, the majority were patients with early onset of dermatosis, in the group of patients with LP – with a late onset after 25 years. Annual manifestations of dermatosis were recorded in the vast majority of patients with psoriasis; in patients with LP, annual manifestations of dermatosis were recorded 12 times less frequently. A family history of psoriasis was found 10 times more often than in the LP group. In patients with psoriasis, compared with patients with LP, a greater relative number of long-term forms of dermatosis (38% of cases versus 22.5%), and early forms of dermatosis, which occurred before the age of 25 (52% of cases, versus 26.5%) were found. The leading provoking factor among patients with psoriasis was recognized as psychoemotional stress (61%), and among patients with LP, infections suffered the days before (49%). Also, in patients with psoriasis, obesity and overweight were recorded 5 times more often, cardiovascular diseases – 3.6 times more often, endocrine disorders – 2.4 times more often, concomitant pathology of the digestive system – 1.5 times more often than in patients with LP. At the same time, comorbital chronic infectious states were recorded more often in LP patients than in patients with psoriasis (31.25% of cases versus 22% of cases). Conclusions. The revealed results of the clinical and anamnestic characteristics of the studied groups turned out to be homogeneous in terms of age characteristics, heterogeneous in gender characteristics, trigger factors, comorbid pathologies, and multidirectional in terms of duration, manifestations and onset of dermatosis, which requires further study and systematization of key parameters.

A clinical assessment of the presence of osteoarthritis (OA) with various localizations, undifferentiated connective tissue dysplasia (uCTD) and joint hypermobility (JHM) in 484 individuals of both sexes of different age groups was carried out. We searched for associations of 4 polymorphic variants of matrix metalloproteinase genes (rs35068180 (MMP3), rs2252070 (MMP13) ), rs226794 and rs2830585 (ADAMTS5)) with the development of osteoarthrosis as a whole, taking into account the localization of the pathological process, the age of the patients, the ethnic origin of the study groups and the presence of undifferentiated connective tissue dysplasia as a whole and its individual phenotypic markers, as well as in the comorbid state with osteoarthritis was carried out. 158 patients had osteoarthritis, 252 had a symptom complex of uCTD, 92 of them were in the comorbid state with OA. The significance of the polymorphic loci of MMP3, MMP13, ADAMTS5 genes in the formation of the symptom complex of uCTD in general and its individual phenotypes was detected. The polymorphic locus of MMP3 gene was associated with OA in the comorbid state with uCTD. Statistically significant models based on clinical-genetic data using the method of multiple logistic regression, that allow predicting the development of osteoarthrosis of knee, hip joints and polyosteoarthrosis were calculated.

The aim of the study – to evaluate the role of expression of specific connective tissue proteins in the formation of the scar on the uterus. Materials and Methods. The study was performed on the basis of the regional perinatal center and KU PB No. 5 during 2017–2019. 426 women with a scar on the uterus were examined, including 115 (27.0 %) with two or more scars. The mean age of the subjects was (33.4±1.1) years. The results of sonographic studies were analyzed. For pathomorphological examination, three cases of intranatal rupture of the uterine wall along the “old” scar after cesarean section from middle-aged women with a gestational age of 33 to 40 weeks are presented. The expression of collagen types 1 and 3 and the protein of the intermediate filaments of the muscle tissue of desmin was determined using a semi-quantitative method with the calculation of H-score. Results and Discussion. Analysis of ultrasound data showed that the average assessment of the degree of insolvency of the scar on the uterus was in the examined women X=(1.3±0.2) points, a high level of insolvency was found in 114 (26.8 %) pregnant women. At the same time, 225 (52.8 %) pregnant women showed no signs of scar failure at all. In 87 (20.4 %) one sign of uterine scar failure was found, in 76 (17.8 %) – two signs, in 20 (4.7 %) – three signs, and in 18 (4.2 %) – four signs. Subsequently, 44 (10.3 %) women were born operatively, the rest gave birth per via naturales. Local myometrial defect after ultrasound delivery was detected in 25 of 182 (13.7 %) women who gave birth independently. Conclusions. A high level of scar failure risk is found in 26.8 % of pregnant women. H-score valuesfor collagen types 1 and 3 averaged (212±24) and (188±22), for desmin – (193±17). Thus, reparative processes at the site of previous surgery on the uterine wall are by incomplete regeneration (substitution) and compensatory hyperplasia of structural tissue elements.

To study hypoxia-inducible transcription factor HIF-1α expression in endometrial polyps (EP) considering their clinical-morphological and immunological features during postmenopause. A complex clinical and laboratory examination of 120 postmenopausal patients was carried out. 90 of them developed EP, whereas 30 had morphologically unchanged endometrium. Immune histochemical (ICH) testing was used to evaluate HIF-1α expression in epithelial and stromal cells of polyps in adjacent and control endometrium. A complex of the most significant risk factors in EP genesis such as high rate of inflammatory disorders of genital organs (IDGO), extragenital, metabolic and endocrine disorders and intrauterine contraception (IUC) was found. High expression of HIF-1α in epithelial cells and in the area of inflammatory infiltrate of glandular fibrous EP stroma was established as compared with control endometrium. HIF-1α expression in epithelial cells and in the area of inflammatory infiltrate of EP glandular fibrous stroma against the background of inflammatory, metabolic and endocrine, immunological changes and age-related involutional processes indicated local hypoxia. Epigenetic changes can develop in the processes of proliferation and apoptosis and in the processes that control neoplastic transformation. The obtained data can provide grounds for patient-tailored EP therapy in postmenopausal patients.
