A study of solid-phase structures of blood serum using wedge-shaped and marginal dehydration methods (Litos system technology) was conducted in order to find out the causes of an inflammatory reaction followed by fibrosis in the second operated joint in a patient with bilateral knee arthritis. The study was aimed at identifying specific morphological markers that characterize the bodys response to the endoprosthesis material. Its solid-phase structures indicated the activation of a hyperergic reaction with daily incubation of blood serum with an alloy of titanium, aluminum, and vanadium. On the contrary, the immunological activity of blood serum can be suppressed and the structures present in it can be transformed into amorphous detritus with the incubation of an alloy of cobalt, chromium, and molybdenum. It was observed from the study that the nature of the immunological reaction of a sensitized organism depends on the type of metals that are part of the endoprosthesis. The immune response causes inflammation of the periarticular tissue, followed by its fibrosation and the formation of a scar demarcation shell that separates the periarticular tissue from the endoprosthesis and performs the function of an immunological barrier on the alloy of titanium, aluminum, and vanadium. On the other hand, an immunological reaction causes the destruction of inflamed periarticular tissue, followed by gradual destruction of the articular bag on the alloy of cobalt, chromium, and molybdenum.

Цель проведённого исследования состояла в оценке эффективности визуального анализа твёрдофазных структур спинномозговой жидкости для диагностики ранних форм нейросифилиса. Методы. Использован метод краевой дегидратации биологических жидкостей, входящий в состав авторской диагностической технологии «Литос-система». Диагностика раннего асимптомного нейросифилиса заключается в выявлении деструктивных образований в форме овалов в морфологической картине твёрдой фазы спинномозговой жидкости. Результаты. Проведён сравнительный анализ результатов исследования спинномозговой жидкости у 19 больных с подтверждённым диагнозом «ранний асимптомный нейросифилис», полученных традиционными лабораторными методами и методом краевой дегидратации. Выявлено, что локализация овалов внутри сферолитов указывает на длительность заболевания нейросифилисом менее трёх лет, а вне сферолитов - от трех до пяти лет. Заключение. Метод краевой дегидратации позволяет диагностировать ранний асимптомный нейросифилис по наличию деструктивных образований в форме овалов в морфологической картине твёрдой фазы спинномозговой жидкости. The aim of this study was to evaluate effectiveness of visual analysis of solid-phase structures in cerebrospinal fluid to diagnose early forms of neurosyphilis. Methods. We used a method of marginal dehydration of biological fluids as a part of the author’s diagnostic technology, Litos-System. Early asymptomatic neurosyphilis is diagnosed based on detection of destructive, oval-shaped formations in the morphological picture of cerebrospinal fluid solid phase. Results. Data from analyses of cerebrospinal fluid performed with traditional laboratory methods and the method of marginal dehydration were compared for 19 patients with documented diagnosis of early asymptomatic neurosyphilis. A localization of ovals within spherulites indicated a less than a three-year duration of neurosyphilis while a localization outside spherulites indicated a duration of three to five years. Conclusion. The method of marginal dehydration allows detecting early asymptomatic neurosyphilis based on the presence of destructive, oval-shaped formations in the morphological picture of cerebrospinal fluid solid phase.

The Copley Medal is awarded to Sir Peter Medawar, C. B. E., F. R. S. Medawar’s first major contribution was to prove conclusively that skin grafts made between different individuals usually fail because of an immunological response made by the recipient against foreign antigens in the donor’s cells, and then to show that the most important mechanism was a specific cell-mediated immunity due to lymphocytes. In attempting to find means of preventing the response against grafted tissues, without impairing immunological capacity in other respects, Medawar made a second major contribution by showing for the first time that it was possible to induce specific tolerance of foreign antigens by administering them to very young animals. His subsequent work, directed towards achieving practical means of overcoming the immunological barrier to tissue transplantation, led him on the one hand to investigate improved methods of inducing specific immunological tolerance and, on the other, to use antiserum against lymphocytes to suppress the damaging effects of these cells. His successful results in experimental animals have indicated the way to their possible application in Man. Medawar’s work has throughout been distinguished by a penetrating clarity of thought combined with insight, and by elegant and original experimental design. He also has a justly high reputation for his analyses and predictions in wider fields of biology, and his study of scientific method.

Antibody Levels

Specific antibodies against estradiol (Es) and progesterone (Pg) are known to modulate blood serum concentrations of these hormones and their biological effects after immunization of animals. It was suggested that specific IgA-Es and IgA-Pg could influence on Es and Pg levels in human blood serum. The purpose of this study was to identify the suggested correlations between serum Es and Pg and specific IgA-Es and IgA-Pg in postmenopausal healthy women (HW) and breast cancer patients (BCP). The serum levels of Es, Pg, IgA-Es and IgA-Pg were studied in 226 HW and 633 BCP by means of solid-phase immunoassay. The following results were obtained. The levels of Es in BCP (0.25 nmol/l) were higher than in HW (0.16; р < 0.0001). The levels of Pg were lower (0.79 vs 0.87; р < 0.0001), and individual Pg/Es ratios were lower (3.19 vs 6.64; р < 0.0001). Individual IgA-Pg/IgA-Es ratios correlated with decrease of Es (rs = -0.15; p = 0.029), with increase in Pg (rs = 0.38; р < 0.0001), and with increased Pg/Es ratio (rs = 0.29; р < 0.0001) in healthy women. Similar correlations were determined in BCP (correspondingly: rs = -0.14, р < 0.001; rs = 0.1, р = 0.009; rs = 0.15, р < 0.0001). The decrease of Es and increase of Pg and Pg/Es in BCP were less significant than in HW: the a quotients in regression у = ах+b (y = hormones levels and x = antibodies levels) in BCP were 3 to 4-fold lower than in HW. These peciliarities of interrelations between hormones and specific antibody levels were revealed only in ER+/PR+ BCP but not in ER+/PR- and ER-/PR- BCP. In conclusion, we have confirmed a suggestion about participation of specific antibodies in regulation of steroids levels in human blood serum. The immune regulation of hormonal status was weakened in BCP.

Neopterin is a non-specific marker of immunological response of human body of cellular type. It belongs to the chemical group known as pteridines. Neopterin has been widely associated with inter alia viral infections, bacterial infections (by intracellular living bacteria), parasitic infections, skin burns or autoimmune diseases. Neopterin is a very important parameter diagnostically not only in diagnosis and monitoring of treatment but also a reliable indicator of macrophages’ activity. Most frequently neopterin concentration is measured in body fluids like blood, serum or urine, but it may be used as an indicator in other body fluids.

Degree Of Anisotropy

The authors examined the composition of biocrystalline structures (anisomorphones) of blood serum in patients with laryngeal cancer. Such structures are formed when blood serum becomes solid, i.e. during its marginal dehydration. The revealed anisomorphones represent three types of marker structures: a marker of a malignant tumor active growth (the aggregation of macroferolite and granular microspherolite with the same degree of anisotropy); a marker of a degenerative-dystrophic process (the aggregation of a macrospherolite with a low degree of anisotropy and microspherolite with a high degree of anisotropy); a marker of a malignant growth progression (a wavy microspherolite without aggregation). The aim of the study is to identify diagnostic markers of the malignant process activity in the solid phase structures of the blood serum in patients with laryngeal cancer and to assess their importance for choosing an effective therapy. Materials and Methods. Marginal dehydration of blood serum was used as the main research method. It is a part of the "Litos-system" diagnostic technology (Marketing authorization FS No. 155, of 2009). Results. It has been shown that the developmental phase of laryngeal cancer (active growth or degenerative-dystrophic process) is an important criterion for choosing treatment options. Surgical treatment is the most effective during the degenerative-dystrophic tumor process, while radiation therapy is preferable during the active phase of malignant growth. Key words: laryngeal cancer, blood serum, marginal dehydration of biological fluids, markers of tumor growth activity. Исследован состав биокристаллических структур (анизоморфонов) сыворотки крови больных раком гортани, которые формируются при переходе сыворотки крови в твердую фазу в процессе ее краевой дегидратации. Выявленные анизоморфоны представляют собой три вида маркерных структур: маркер активного роста злокачественной опухоли – агрегация макросферолита и зернистого микросферолита с одинаковой степенью анизотропии; маркер дегенеративно-дистрофического процесса – агрегация макросферолита с низкой степенью анизотропии и микросферолита с высокой степенью анизотропии; маркер прогрессии злокачественного роста – волнистый микросферолит вне агрегации. Цель – выявить диагностические маркеры активности злокачественного процесса в структурах твердой фазы сыворотки крови больных раком гортани и оценить их значение для выбора эффективного вида лечения. Материалы и методы. В качестве основного метода исследования использован метод краевой дегидратации сыворотки крови, являющийся разделом диагностической технологии «Литос-система» (Разрешение ФС № 155 от 2009 г. на применение в клинической практике). Результаты. Показано, что фаза развития рака гортани (активный рост или дегенеративно-дистрофический процесс) служит важным критерием выбора вида лечения: в фазу дегенеративно-дистрофического процесса опухоли наиболее благоприятный эффект дает хирургическое лечение, а в период активной фазы злокачественного роста – лучевая терапия. Ключевые слова: рак гортани, сыворотка крови, краевая дегидратация биологических жидкостей, маркеры фазы активности опухолевого роста.

Positive Correlations

Specific antibodies against environmental chemical gene toxicants and endogenous steroid hormones are shown to modulate concentrations of these compounds in blood serum and their biological effects in experimental models. However, probable hazards of such antibodies in human teratogenesis are still unknown. In particular, potential correlations between specific serum antibodies, sex hormone levels in pregnant women, and congenital malformations in newborns are not clear. The aim of this study was to identify possible associations between occurrence of antibodies to benzo[a]pyrene, estradiol and progesterone (Bp, Es and Pg, respectively), and congenital malformations, and effects of these antibodies upon Es and Pg concentrations in blood serum of pregnant women. We have included into the study 182 women with normal pregnancy and 101 females with congenital malformations of fetus. A non-competitive solid phase immunoassay was performed using Bp, Es and Pg conjugated to bovine serum albumin as antigens. Es and Pg serum concentrations were measured using immunoassay test-systems of “Immunotech” (Moscow). Results: strong positive correlations were revealed between the levels of studied antibodies in the both groups. High IgA-Bp/IgA-Es (> 3) and IgA-Bp/IgA-Pg ratios (> 3) were associated with congenital malformations (OR = 2.2, p = 0.013 and OR = 6.8, p < 0.0001). Positive correlations were revealed between Pg/Es and IgA-Bp/IgA-Es (rS = 0.62, p < 0.0001), and IgA-Bp/IgA-Pg ratios (rS = 0.77, p < 0.0001) in cases with inborn malformations. Similar correlations were found for the women who had normal pregnancy (rS = 0.4, p = 0.0001, and rS = 0.23, p = 0.026, respectively). The Pg/Es proportion correlated with IgG-Bp/IgG-Es (rS = 0.46, p = 0.002), and with IgG-Bp/IgG-Pg ratio (rS = 0.5, p = 0.0009) in cases of malformations, but not in women with normal pregnancy. Conclusion: we have revealed novel associations between congenital malformations of fetus and ratios of IgA-Bp/IgA-Es, as well as IgA-Bp/IgA-Pg, like as positive correlations between hormonal Pg/Es proportions, and ratios of specific antibodies in pregnant women.

Aim. Blood serum and urinary procalcitonin (PCT) concentration in healthy persons was studied. Materials and methods. A single-stage observational study of case-control type was performed. The study included 32 men and 37 women of middle age (53.4 16.4 years) with normal renal function. PTC concentration was determined with the method of solid-phase enzyme immunoassay using test-system (Procalcitonin IFA-BEST, Russia). Results. Blood serum PCT concentration in the examined persons was 0.029 0.016 ng/ml (M SD). The number of blood serum samples with PTC level 0.05 ng/ml was 5.8 % (4 from 69). The mean urinary PTC concentration by 72.59 times exceeded the mean blood serum PTC content and was 2.12 1.832 ng/ml (р 0.000001). Coefficient of variation of results for the urine by 1.57 times exceeded the analogous index for the blood serum. When comparing the results of blood serum and urine analyses, no statistically significant differences between men and women were revealed. When estimating the coefficients of linear correlation between PTC content in the blood serum and urine, a weak positive dependence was established (R = 0.302782). Conclusions. High PTC concentration in the urine permits to suppose that one of the ways of procalcitonin removal from the blood plasma is its elimination by kidneys in unchanged type by means of glomerular filtration.

Postpartum infectious diseases are ranked second (WHO, 2016) in the structure of maternal mortality and complicate postpartum period. Most of the existing methods allow to diagnose diseases in the presence of an already deployed clinical picture. The objective: of the work is to improve the diagnosis and prediction of pospartum endometritis by applying the method of fluorescence spectroscopy. Materials and methods. The main group is -120 women in the postpartum period with postpartum endometritis, the control group is 38 women with uncomplicated postpartum period. A study of their blood serum was carried out using the method of fluorescence spectroscopy. Results. Within the framework of the study, independent prognostic factors of the emergence of postpartum endometritis are inflammatory diseases of the lower department of the genital tract (p=0.01), abnormalities of labor (p=0.006) and TORCH infections (p=0.001). True markers for diagnosis of postpartum endometritis are the reduction in blood serum fluorescence intensity (IF) (p<0.0001) and the shift in magnitude lmax to the long-wave region (p=0.007). Conclusion. The use of spectrum-fluorescent blood serum markers in the comprehensive diagnosis of postpartum endometritis allows to diagnose reliably thе onset and to predict the course of the disease, including the treatment process. Key words: endometritis, postpartum purulent inflammatory diseases, method of fluorescence spectroscopy.
