Introduction. The article adduces the obtained results of the indices of immune homeostasis in the development of combined pathology (experimental pneumonia (EP) and gastric ulcer (GU) of the stomach). The immune system is characterized by the number of T-lymphocytes since they are the basis of the cellular component of the immuneresponse and the concentration of b-lymphocytes and circulating immune complexes (CIC), which are responsible for cellular immunity.The aim of the study – the content of T-lymphocytes, CEC to assess the immune system in the development of EP and GU.Materials and Methods. This experimental study was conducted on 39 guinea pigs-males. Experimental pneumonia caused by the method of V. N. Shliapnikova, T. L. Solodova [et al.] Gastric ulcer of the stomach wassimulated by the method of V. I. Komarova. We determined the content of T- and B-lymphocytes (SD3 and SD19) in the blood by the method of E. F. Chernushenko, L. S. Kohosova. The level of circulating immune complexes (CIC) in the blood by the method of Haskova V., Kaslik J..Results and Discussion. The results of experimental studies established that early period of development (4th and 8th day) of gastric ulcer and pneumonia is characterized by the following changes of immune homeostasis: decrease in the level of T-lymphocytes and elevated levels of lymphocytes and circulating immune complexes in the blood of Guinea pigs.Conclusion. A depression of cell growth and humoral types of immunity in terms of experimental pneumoniaand gastric ulcer was revealed.

In this paper, it is shown that the modeling process of bronchial asthma (BA ) is accompanied by changes, in comparison with the control group, in the indicators of immune system response: T- & B-lymphocytes, circulating immune complexes in blood of guinea pig males on the 4th, 18th, 25th day of experiment.The aim of the study – determination of some indices of immune system in blood of guinea pigs in the modeling process of BA on 4th, 18th, 25th day of the experiment.Materials and Methods. Experiments were conducted on 40 guinea pigs (males), with body weight 0.25–0.27 kg. Animals were divided into four groups of ten animals in each. Intact guinea pigs were the first group. Animals with experimental BA – the second, third, fourth group respectively on the 4th, 18th, 25th day of the experiment. Experimental BA was reproduced by V. I. Babych method. In blood of intact guinea pigs and animals with experimental BA , the number of T- and B-lymphocytes was determined by the method of E. F. Chernushenko, L. S. Kohosov, determination of the level of circulating immune complexes was carried out by the method of V. Haskova and co-authors. The results of the study were processed by the method of variation statistics using Student's criterion.Results and Discussion. The results of the studies showed unidirectional changes in individual parameters of the immune system, depending on the periods of the formation of BA : an increase in the number of B-lymphocytes and circulating immune complexes, a decrease in the number of T-lymphocytes for all of the studied days of the experiment.Conclusions. The obtained results indicate significant changes in the immune system parameters in the blood of experimental animals with BA and are important for understanding the pathogenesis of BA .

The influence of the chronopharmacological scheme of treatment with the use of exogenous Melatonin in the form of the Melaksen drug on the immunity status of psoriasis patients has been studied. The study of the immunity status consisted in determination of the main Manchini classes of immunoglobulins A, M, G, the level of circulating immune complexes by the method of selective precipitation in 3% polyethylene glycol. In addition, we determined the subpopulation of lymphocytes carrying CD3, CD4, CD8, CD16, CD 25, and CD72 antigens by the immunofluorescent method. In has been found that Melatonin in psoriasis patients exerts the immunomodulatory action on the immune system at the combined treatment (due to an increase in the number of -lymphocytes with cytotoxic-suppressive properties at obvious signs of immune disbalance in the form of the increased ratio of Т CD4+ and CD8+).

The results of studying the effect of interferons alpha and gamma and their combination with dimethyl dipyrazolyl selenide on the immune status and functional state of the reproductive system of cows in adverse ecological conditions are presented. The positive effect of the drugs, especially their combination, on erythropoiesis and the immune status of animals, which was manifested by an increase in the content of erythrocytes, hemoglobin, hematocrit, leukocytes, total immunoglobulins, serum bactericidal and lysozyme activity, absorptive function of phagocytes, relative amount of T lymphocytes, and a decrease in the level of circulating immune complexes was stated. An increase in the immune status of animals at the effect of immunocorrecting drugs was accompanied by a decrease in the pathology of calving and postpartum complications and favorably affected the functional state of their reproductive system. The cows which were introduced interferons and their combination with dimethyl dipyrazolyl selenide demonstrated a shorter period from calving to successful insemination, as well as the insemination index and fertility, compared with the animals of the control group, which were not introduced any drugs.

Aim. To assess the clinical and immunological features in patients with chronic opisthorchiasis, depending on the duration of the infection. Methods. The first group consisted of 19 patients with the duration of the infection up to 1 year, the second group consisted of 21 patients with the duration of the infection between 1 and 5 years, the third group was formed of 23 patients with the duration of the disease more than 5 years, the control group 20 healthy individuals. Immunological research was carried out at the Clinical Diagnostic Center. Statistical processing was performed using Microsoft Excel 2010 and Statistica 6.0 software. The statistical significance of differences was determined by using the MannWhitney test (U-test) at the level of significance of p 0.05. The correlations were assessed by calculating Spearman's rank correlation coefficients.Results Clinical features of chronic opisthorchiasis were revealed in the disease duration groups of up to 1 year, from 1 year to 5 years, more than 5 years: the subclinical course was most common in the group of up to 1 year; cholangiohepatitis prevailed in the group of between 1 to 5 years, allergic skin syndrome, cholangiocholecystitis and pancreatitis dominated in the group of more than 5 years. The immune response in chronic opisthorchiasis was characterized by: up to 1 year lymphocytosis, increased levels of immunoglobulins M (IgM) and circulating immune complexes (CIC), a decrease in the number of T-lymphocytes (CD3+), as well as an increase in bactericidal activity of leukocytes (BAL); between 1 and 5 years monocytosis, increased levels of immunoglobulins M, immunoglobulins G and circulating immune complexes, a decrease in T-cytotoxic lymphocytes (CD8+) and nitro blue tetrazolium (NBT test), as well as an increase in NK cells and phagocytic activity of monocytes, more than 5 years eosinophilia. Conclusion. Common features of rearrangement of the immune system in opisthorchiasis: inflammatory changes in the hemogram, activation of humoral immunity with parallel suppression of the cellular component of the immune system, and increased phagocytosis.

Exosomes are extracellular vesicles (EV) of endosomal origin (multivesicular bodies, MVB) constitutively released by many different eukaryotic cells by fusion of MVB to the plasma membrane. However, inducible exosome secretion controlled by cell surface receptors is restricted to very few cell types and a limited number of cell surface receptors. Among these, exosome secretion is induced in T lymphocytes and B lymphocytes when stimulated at the immune synapse (IS) via T-cell receptors (TCR) and B-cell receptors (BCR), respectively. IS formation by T and B lymphocytes constitutes a crucial event involved in antigen-specific, cellular, and humoral immune responses. Upon IS formation by T and B lymphocytes with antigen-presenting cells (APC), the convergence of MVB towards the microtubule organization center (MTOC), and MTOC polarization to the IS, are involved in polarized exosome secretion at the synaptic cleft. This specialized mechanism provides the immune system with a finely-tuned strategy to increase the specificity and efficiency of crucial secretory effector functions of B and T lymphocytes. As inducible exosome secretion by antigen-receptors is a critical and unique feature of the immune system this review considers the study of the traffic events leading to polarized exosome secretion at the IS and some of their biological consequences.

The features of the rehabilitation of the immune system of piglets after weaning were studied in connection with different seasons of farrowing. To fulfill this goal, 4 groups were formed from the offspring of sows of the SM-1 breed of Novosibirsk selection. The 1st group included piglets from winter farrowings, and the 2nd, 3rd and 4th groups, respectively, young animals born in spring, summer and autumn. Each group consisted of 30 animals. Studies of indicators of the immune status were carried out before weaning and 30 days after weaning. Weaning of piglets from sows with their subsequent regrouping in the educational farm «Tulinskoye» is carried out at the age of 60 days. The research results have shown that the state of the immune status of 2- and 3-month-old pigs is seasonal. Piglets born in autumn show the best indicators of leukopoiesis, T-, B-lymphopoiesis, the formation of functionally mature T-lymphocytes, activated T-lymphocytes and antitelogenesis. The second position in terms of the intensity of leukopoiesis, antitelogenesis and B-lymphopoiesis is occupied by young animals born in summer. Piglets raised in winter differ from their peers in a low level of IgM synthesis, while piglets born in spring have the lowest total numbers of T-lymphocytes, T-helper inductors, T-killer suppressors, B-lymphocytes and IgG. A month after weaning, animals, regardless of the season of birth, showed a statistically significant decrease in T-lymphopoiesis. The activity of the T-link of the immune system decreased most significantly in young animals obtained in spring. However, in contrast to their peers, youngsters born in the spring showed a statistically significant increase in blood IgM and IgG concentrations. In piglets born in winter, summer and autumn, the activity of IgM synthesis, on the contrary, decreased, while the formation of IgG remained at the same level.

The immune system of 90-day old piglets of SM-1 Novosibirsk breed piglets depends on sex and stress-reactivity. Stress-reactivity was measured using halothane test. The immunologic testing was performed 30 days after weaning. Our results show that overall piglet immune system demonstrated high proliferative activity of T- and B- immunocompetent cells with active formation of mature active T-and B-lymphocytes and did not show signs of immunosuppression. Compared to guilts, barrows had higher concentration of leucocytes, T-and B-lymphocytes, killer-supressor T-cells, activated and poorly differentiated T-lymphocytes. Gilts had higher production of inductor-helper T-cells, IgM and IgG when compared to barrows. Stress-resistant piglets had higher concentration of B-lymphocytes, IgM and IgG whereas stress-sensitive piglets had higher concentration of T-lymphocytes, supressor-killer T-cells and thymus T-lymphocytes. Gilts had higher concentration of inductor-helper T-cells than killer-supressor T-cells. Gilts overall had intensive antibody synthesis, however, stress-resistant gilts had higher IgG synthesis compared to stress-sensitive gilts. In barrows immature T-lymphocytes differentiated mainly into killer-supressor T-cells. The adaptivity of barrow immune system was characterized by high circulatory B-lymphocytes and IgM. Stress-sensitive barrows had lower antibody synthesis levels and higher T-lymphophoesis compared to stress-resistant barrows.

Introduction. There is not much data about the composition of populations of the immune system in acute appendicitis. The basic histopathological criterion for the diagnosis of acute appendicitis is neutrophil infiltration of the muscle membrane. Aim. The subject of this publication is a semi-quantitative evaluation of B lymphocytes (CD20+), T lymphocytes (CD3+) and macrophages (CD68+), and the determination of the number of active lymph nodes during the course of inflammation.Material and Methods. The study material was obtained from 79 patients who had an appendectomy due to acute appendicitis. In this group, the tissue was obtained from: 34 women (aged 20 to 91) and 45 men (aged 20 to 72).Results. In the course of acute appendicitis, there is involvement of lymph node B lymphocytes, T lymphocytes and macrophages. Independent of the type of inflammation, the cellular make-up of the nodes is similar. The number of lymph nodes decreases with age and is gender dependent.Conclusions. In the course of acute appendicitis, there is involvement of lymph node B lymphocytes, T lymphocytes and macrophages. The number of lymph nodes decreases with age and is gender dependent. A statistically significant number of the examined cells of the immunological system in the lymph nodes changed due to inflammation (p<0.001). B and T lymphocytes in the lymph nodes and in the mucous membrane of the appendix differed depending on the sex, and the presence of B lymphocytes in the mucous membrane was significantly higher in the group of 20-40 years of age. T lymphocytes were predominant in the centres of the lymph nodes in groups 20-40 and 61-91 years of age, and in the peripheral zones in the group of 41-60 years of age.
