The aim: to study and compare the features of the interleukins levels and morphological changes of placenta at various stages of preeclampsia. Materials and methods: 109 pregnant women with preeclampsia of varying severity (study group) and 30 pregnant women with uncomplicated pregnancy (control group) were examined. Immunohistochemical method, proinflammatory interleukins levels, morphological and morphometric analysis of peripheral and central placental areas biopsies on the optical and electron-microscopic level have been used. Results: Morphofunctional changes in the placenta in case of preeclampsia and the increase in the expression level of the transforming growth factor have a series of regular stages from the formation, strain and disruption of adaptive mechanisms with more pronounced signs of morphological immaturity of parenchymal and stromal elements of the placenta, especially in the area of syncytiotrophoblast and spiral vessels. The degree of clinical manifestation of preeclampsia has a correlation relationship with IL-10 deficiency and with the increase in TNF-α, stimulation of macrophage-protein production that contributes to the change in the ratio of Thl / Th2, which are antagonists and inhibit each other’s development. Conclusions: The severity of the preeclampsia course correlates with the state of morphofunctional changes in the placenta and changes in the ratio of the pro- and anti-inflammatory interleukins.

СОСТОЯНИЕ ГЕМОДИНАМИКИ У БЕРЕМЕННЫХ С ОЖИРЕНИЕМ - В данной статье представлены изменения состояния гемодинамики у беременных с ожирением при неосложнённой беременности. В исследование включены результаты комплексного обследования 84 беременных в возрасте от 23 до 28 лет с ожирением различной степени выраженности при сроках гестации 36-38 недель. В контрольную группу вошла 21 беременная аналогичного возраста и срока гестации с нормальной массой тела. У всех наблюдаемых пациентов беременность согласно консультациям акушер-гинекологов была признана неосложнённой. Степень ожирения оценивали по индексу массы тела. Проведённое исследование показало, что избыточный вес тела по мере её прогрессирования оказывает крайне неблагоприятное влияние на гемодинамику и функциональное состояние сердечно-сосудистой системы в целом, снижает коронарные резервы. Наиболее выраженные нарушения функционального состояния сердечно-сосудистой системы имеют место при ожирении II и III степеней.<br />СТАН ГЕМОДИНАМІКИ У ВАГІТНИХ З ОЖИРІННЯМ - Уданій статті представлено зміни стану гемодинаміки у вагітних з ожирінням при неускладненій вагітності.

Pregnancy miscarriage is a consequence of many factors. The aim of the study was to analyze the effect of miscarriage gene on embryometric, ultrasound, hormonal, immunological parameters in pregnant women, and to evaluate its prognostic value. The main group includes 31 pregnant women who had clinical signs of miscarriage in current or previous pregnancy. The control group consists of 32 healthy pregnant women whose clinical-paraclinical parameters served as a control to compare the data of the pregnancy survey of the main surveillance group. A general clinical examination and a special obstetrical examination (complaints, anamnesis, general medical examination, obstetric examination), biochemical studies (determination of hormones of the fetoplacental complex in blood serum of pregnant women), ultrasound, immunological studies, histological studies of the placenta, molecular genetic study A1166C polymorphism of the AGTR1 gene were made. In the course of the research, the genetic determinism of miscarriage was discovered. The polymorphism of the A1166C of the AGTR1 gene was considered as a prognostic marker of miscarriage in early gestational term and preeclampsia in the second half of pregnancy. A reliable marker of abortion was the maternal genotype 1166AC for the genome AGTR1. The risk of occurrence of clinical manifestations of abortion increased five times. At simultaneous influence of all prognostic factors the risk of abortion increased 6,25 times. Detection of genetic markers of pregnancy miscarriage will allow early correction of this pathology and prevent perinatal loss.

Silver staining at the electron microscopic level of the nucleolar organizers was carried out on Xenopus laevis oocytes at various stages of oogenesis. The results indicate that a positive reaction takes place exclusively in the dense fibrillar component of the extrachromosomal nucleoli. This constituent undergoes morphological changes of distribution and architecture, which have been correlated with modifications of the transcriptional activity of the nucleoli. When nucleolar activity is reduced, during previtellogenesis, this constituent appears as dense homogeneous spherules well-segregated from the granular component. In contrast, when nucleolar activity is high, during vitellogenesis, it forms an heterogeneous area with an ill-delimited outline: it is organized into a fibrillar core with emerging skein-like strings. It thus seems that this constituent remains silver-stained throughout oogenesis. These findings suggest that the method used would allow one to follow the evolution of the nucleolar organizer region (NOR) topography during oogenesis. Moreover, they point out facts that have relevance to the problem of the correlation between Ag stainability of NORs and nucleolar transcriptional activity.

Purpose: Growth differentiation factor-15 (GDF- 15) protein belongs to a transforming growth factor-β family which determines the growth and differentiation of cells. In cancers, GDF-15 influences on the proliferation, differentiation, viability, migration and invasiveness of cancer cells. The aim of our study was to evaluate the expression of GDF-15 in the tissue and its levels in sera of patients with colorectal cancer. Materials and methods: The level of GDF-15 in the sera of 55 patients diagnosed with colorectal cancer was determined using the ELISA method whereas expression of this protein was performed by immunohistochemical method. Results: The mean value of GDF-15 levels in the sera of patients with colorectal cancer was significantly higher than in healthy control group (p<0.001). The expression of GDF-15 in the tissue was weak, moderate and strong in 23.6%, 15.7% and 60.7% cases, respectively. Statistical analysis showed that the expression of GDF-15 correlated with patients’ age (p<0.005) and non-mucinous type of cancer (p<0.001). The high GDF-15 levels in the serum was associated with tumor size (p<0.01) and distant metastases (p<0.05). Conclusions: According to our results, we postulate that the level of GDF-15 in serum can be use to assess the metastatic behavior of colorectal cancer

The differential tissue distributions of aztreonam and ceftazidime within fibrin clots infected with Pseudomonas aeruginosa, Enterobacter cloacae, and Serratia marcescens, their efficacies, and the in vivo bacterial morphological changes induced by these drugs were evaluated. Rabbits were given intravenously a single dose of 100 mg of either agents/kg of body weight. In the cores of the clots, the peak levels of both drugs were much lower than those observed in the peripheries and in serum. Aztreonam's half-lives within the peripheries and in the cores of the fibrin clots were up to six times higher than observed in serum, while ceftazidime's half-lives in clots were twice that observed in serum. This resulted in a much greater penetration ratio for aztreonam than for ceftazidime. Both drugs controlled the growth of P. aeruginosa in vivo, but E. cloacae and S. marcescens responded better to ceftazidime. Morphological changes were more abundant in the peripheries than in the cores of the clots. In the control group, P. aeruginosa's morphology in the cores was different than that in the peripheries of the clots. Against P. aeruginosa, aztreonam did induce morphological changes in the cores while ceftazidime did not. Electron microscopic studies revealed that morphological changes associated with aztreonam seemed different than those of ceftazidime. Along with elongation of bacteria, more bow tie and herniated bacteria were observed with aztreonam. Though both agents selectively affect PBP 3, as manifested by elongated bacteria, they induce in the peripheries of the clots thickening, breaks, and detachment in bacterial cell walls, alterations which are generally associated with antibiotics affecting PBP 1a and 1b.

A lot of research nowadays is dedicated to the problem of habitual pregnancy loss, and this attention is dictated by the continued high frequency of this condition. The pathogenesis of habitual pregnancy loss is very complicated and includes many factors, at present especially close attention is paid to immune aspects. It is considered, that cytokine imbalance might play a key role in the pathogenesis of habitual pregnancy loss. Examination of 38 pregnant women was carried out at 5-12 weeks of gestation. The main group consisted of 17 women with habitual miscarriage and the threat of interruption at the time of the examination, the control group consisted of 21 women with uncomplicated pregnancy and a favorable obstetric history. As the material for investigation peripheral blood was used. Serum level of a complex of cytokines IL-1β, IL-2, IL-4, IL-5, IL-6, IL-9, IL-10, IL-12p70, IL-13, IL-17A, IL-18, IL-21, IL-22, IL-23, IL-27, IFNγ, TNFα, GM-CSF was assessed on the Luminex 200 multiplex fluorescence analyzer (Luminex Corporation, USA). The significant differences in the serum level of IL-1β, IL-22, IL-23 and IL-27 were observed between the groups, in the main group their level was higher comparing to that of healthy pregnant women. When evaluating the cytokines serum level, fairly high values of IL-27 (in 25%of cases) (p<0,05), TNFα - (in 18% of cases) (p>0,05) were found in the main group, while in the control group they were not registered. Significant differences in the serum level of IL-2, IL-4, IL-9, IL-12p70, IL-18 and IFNγ were not noted in the compared groups (p>0,05). The simultaneous increase in the serum level of pro- and anti-inflammatory cytokines observed in our study can be explained by both an increase in the immune response and triggering of fetoprotection mechanisms. Inadequate cytokine regulation may be a prerequisite for the development of conditions for the development of a threat of termination of a real pregnancy in women with habitual miscarriage.

We describe a simple indirect immunohistochemical method for localization of acetylcholine receptors (AChR) in motor endplates at the light and electron microscopic level. This method involves the use of a monoclonal antibody directed against the main immunogenic region (MIR) of AChRs and is applicable to periodate-lysine-paraformaldehyde (PLP)-fixed tissue. We discuss the advantages of this method, as compared with the alpha-bungarotoxin-immunoperoxidase technique, and stress its value for diagnostic investigations of motor point biopsies from patients with neuromuscular transmission disorders.
