Introduction. The protection of the body against external and internal antigenic factors is executed with the help of the primary cellular and secondary resistance links. Excessive activation of adaptation reactions leads to the formation of various pathologies of inflammatory nature. Changes in the immune responses occur at all ontogenesis stages. In the present study, we conduct the experiment of induced peritonitis in animals of different ages in order to investigate more accurately adaptive responses of the immune system during inflammation. Objectives. The aim of our research was to study changes in the indicators of adaptive humoral immunity, levels of immunoglobulin A and circulating immune complexes, phagocytic activity of neutrophils and the disruption of enzymes activity, which provide the phagocyte function in the NST test on the model of induced peritonitis in animals of different ages. Materials and methods. The studies were performed on 200 white male rats. They were divided into a control group and the experimental rats, 3- and 22-month-old ones. Acute inflammation and dysbiosis in the small intestine were caused by intraperitoneal injection of lipopolysaccharide obtained from Escherichia coli strain. The material for the study was serum and blood elements of experimental animals. Results. The levels of immunoglobulin A in the blood serum of 3 and 22-month-old rats with the inflammation model were reduced in comparison with this index in control group animals. The content of the CIC in the rats blood serum of both age groups was significantly higher in comparison with the control group. All the studied indices of neutrophils phagocytic activity in the 22-month-old animals with the inflammation model were lower than in the control rats of this age. In the 3-month-old rats with the inflammation model, the index of phagocytosis completeness was significantly lower in comparison with the control group. The reduction in the reserve capacity of phagocytic cells was higher in the 22-month-old animals. An increase in the neutrophils metabolic activity and a decrease in their metabolic reserve in 3 and 22-month-old rats with the inflammation model were revealed in comparison with the parameters of the control groups. Conclusions. The results of the study indicate presence of violation of the primary cellular and secondary humoral immunity during the aging of the body and decrease in the adaptive responses of the immune system during inflammation due to an increase in antigenic effects.

Salivary Immunoglobulin A

While research indicates that high stress may be immunosuppressive, little is known about the effects of relaxation on the immune system. To determine whether relaxation is immunoenhancing, 50 volunteer college students were randomly assigned to one of four relaxation methods (Benson's relaxation response, guided visualization, massage, lying quietly with eyes closed, or a touching-control group). Salivary immunoglobulin A (S-IgA) and salivary Cortisol levels were recorded before and after one 20-min. relaxation session. Subjects in the relaxation response, visualization, and massage groups showed a significant increase in S-IgA concentrations from the before to the after relaxation samples. Also, post-relaxation S-IgA concentrations were significantly higher in the relaxation response, visualization, and massage groups than in the touching-control group. Salivary Cortisol did not change significantly. These data suggest that one component of the immune system, S-IgA, may be enhanced by the practice of a coping skill such as relaxation.

AbstractSerum immunoglobulin (IgG, IgA and IgM) levels were determined in patients with chronic tonsillitis before and one month after tonsillectomy. The preoperative levels of serum IgG, IgA and IgM were significantly higher when compared with the controls. The increase may be due to repeated antigenic stimulation. The post-operative levels for the three immunoglobulins were decreased; however, a significant reduction was observed for IgG only where the mean value was comparable with the control group. The data confirm that tonsillectomy does not disturb the humoral immune system of the body.

The immune system is central to ensuring the consistency of the body's homeostasis. The state of the body's natural resistance is determined by a set of non-specific protective mechanisms. Lymphocytes and phagocytes are actively involved in maintaining immunity. Lymphocytes recognize the antigens of pathogenic microorganisms, and phagocytes absorb and destroy the pathogens themselves. During the weaning of piglets from sows there is a decrease in the protective forces of their body. During this period, the natural resistance of the piglets is reduced due to the stressful situation caused by changing conditions of confinement, the transition to full feed and lack of sows. The immune system of weaning pigs is relatively weak, so when exposed to environmental and technological stressors, they become susceptible to various diseases. The use of probiotic drugs stimulates the activity of the immune system, prevents stress and immunodeficiency. One of these probiotics is the probiotic of domestic production Protecto-active. It w observed the the influence of the probiotic Protecto-active on the indices of nonspecific resistance of the young pigs organism to the growth. An increase in bactericidal activity of blood serum by 12.10% (P <0.05) and lysozyme activity of blood in the piglets of the experimental group was increased by 3.71% compared to control, which indicates the activation of the body's defenses and the increase in adaptive capacity. An important step in the study of the influence of the probiotic Protekto-active on the state of the immune system is to determine the phagocytic activity of neutrophils, phagocytic index and phagocytic number. In the experimental group of piglets that were fed the probiotic Protecto-active, we found an increase in leukocyte phagocytic activity by 9.0% (P <0.001), a phagocytic index by 51.7% (P<0.001) and a phagocytic number by 24.8% ( P <0.01) compared with the control group. Thus, using a probiotic Protecto-active, all indicators of phagocytosis increase: the number of phagocytes increases, their ability to capture microorganisms and increases their digestive capacity, it increases the bacterial and lysozyme activity of blood serum, which is positively reflected in the immunobiosity. Key words: probiotic, phagocytosis, phagocytic index, phagocytic number, phagocytic activity of leukocytes, cellular immunity, piglets

We have studied the effect of nanocrystalline cerium dioxide (NCD) on the morphological state of the gastric mucosa and colon in rats of different ages. It was found the degenerative changes and dysregeneration (violation the ratio of value of major and parietal cells), atrophic or hyperplastic changes. NCD restored the processes of differentiation and proliferation of epithelial cells of gastric glands. In the control group of old rats mucosa of the colon was focal thinner, the cells had degenerative changes, it was observed the change in nuclear-cytoplasmic ratio of cells, were found foci of infiltration of lymphocytes, macrophages, plasma cells. NCD in old rats caused a decrease in the number of cells in a state of degeneration and apoptosis, increased proliferative activity of cells increased the number of goblet cells. Thus, NCD restored morpho-functional structure of the mucous of the stomach and colon.

Abstract Background The aim of this survey was to determine the effects of an aerobic physical training program of six months duration on the serum and urinary concentrations of essential trace elements among middle distance runners and untrained, non-sportsmen participants. Methods 24 well-trained, middle-distance (1500 and 5000 m), aerobic male runners (AG) were recruited at the beginning of their training season and 26 untrained males formed the control group (CG). All participants were from the same region of Spain, and all of them had been living in this area for at least two years. Serum and urine of samples of Cobalt (Co), Copper (Cu), Manganese (Mn), Molybdenum (Mo), Selenium (Se), Vanadium (V) and Zinc (Zn) were obtained at the beginning of the training season, and six months later, from all participants. All samples were analyzed with inductively coupled plasma mass spectrometry (ICP-MS). Results Two-way ANOVA showed significant differences relative to group effect in serum concentrations of Co, Cu, Mn, Mo, Se and Zn. Attending to time effect, there were differences in Mn (p = 0.003) and Zn (p = 0.001). The group x time interaction revealed differences only in the case of Mn (p = 0.04). In urine, significant differences between group were obtained in Co, Cu, Mn, Se and V. Time effect showed changes in Co, Cy, Mo and Se. Finally, the group and time interaction revealed significant differences in urinary Cu (p = 0.001), Mn (p = 0.01) and Se (p = 0.001). Conclusions A six-month aerobic training program for well-trained athletes induced modifications in the body values of several minerals, a fact which may reflect adaptive responses to physical exercise. The obtained data could be interesting for physicians or coaches in order to consider specific modifications in sportsmen’s diets as well as to determine specific nutritional supplementation strategies.

The immune response in animals and hu-mans is a biological defense mechanism against negative environmental factors. The immune system is a complex of organs and cells of the body, that reacts (protects) against foreign objects-protozoas and hel-minths. The aim of the study was to investi-gate the dynamics of cellular factors of the immune system of healthy minks, experi-mentally invaded with eimeriidosis against the background of specific immunocorrec-tive therapy. To study the dynamics of T-lymphocytes in the blood of animals, being at the specific immunocorrective therapy, a single-center prospective blind randomized comparative study was conducted in parallel groups. At the initial stage of the study, 56 male minks were isolated from the general population. The first group of clinically healthy animals was the control group. From the second to the sixth groups, animals were spontaneously infected with eimerias and isospores. Animals from the third and fifth groups were treated with coccidiostatic "Stop-coccid". Mink of the 4th and 6th groups received the drug "Ametherm 5%". Minks in the 5th and 6th groups after treat-ment with coccidiostatic were adninistered an immunomodulatory drug of plant origin "Phytodoc-immunostim". The 7th group served as an additional control and received a placebo-water with starch. Thus, the analy-sis of the results of the clinical study showed that the use of specific and immunocorrec-tive therapy has a positive effect on the dy-namics of T-lymphocyte levels in the blood of animals with eimeriidosis. In group 3, where infected minks were treated with "Stop-coccid", the level of T-lymphocytes increased by 35.8% to 41.1%; in the 4th group (administered "Ametherm 5%") the level of T-lymphocytes rose from 35.2% to 42.3%; in the 5th group (administered “Stop-coccid” and immunomodulator) the level of T-lymphocytes changed from 36.5% to 43,0% in the 6-th experimental group (treated "Ametherm 5%" and immunomodu-lator) the level of T-lymphocyte growth from 38.6% to 43.9 per cent.

Objective: To study the features of clinical manifestations, cellular and humoral immunity of newborns with intrauterine mixed infections (IUMI). Methods: A comprehensive survey of 45 infants with IUMI was carried out. Depending on the classification of IUMI they were divided into 3 main groups: group I – 24 patients (53%) with the viral-bacterial association, group II – 12 patients (27%) with the viral-viral association, and group III – 9 patients (20%) with the viral-parasitic association. The control group consisted of 10 newborns born from uninfected, somatically healthy mothers. Diagnosis of IUMI was based on the detection of specific antibodies of the IgA, IgG and IgM classes, as well as phagocytic activity and phagocytic index of leukocytes. In addition, general clinical, biochemical, bacteriological and instrumental research methods have been conducted. Results: The blood serum IgA and IgM indices in patients of the main group were significantly higher, and the mean IgG values were lower compared to the control group. Analysis of cellular immunity parameters in the main group showed a decrease in the number of mature T-lymphocytes (CD3), B-lymphocytes (CD20), the number of T-helpers and cells that produce IL-2 in the peripheral blood, compared with the control group. In the main group, there was also an increase in the number of apoptosis cells (CD95), cells with high cytotoxic activity (CD25, CD71) and the percentage of natural killer cells (CD16). A decrease in the phagocytic activity and phagocytic index of neutrophils was recorded, which indicates the insufficiency of the nonspecific component of immunity. Conclusions: In newborns, various changes were found both on the part of specific and nonspecific components of immunity. This indicates the development of secondary immunodeficiency in this category of patients and makes it necessary to add to the main treatment of immune corrective therapy.

Abstrak Pseudomonas aeruginosa adalah bakteri penyebab infeksi terbanyak yang resisten terhadap antibiotik. Glutamin adalah asam amino yang terdapat dalam tubuh yang salah satu fungsinya dapat memodulasi imunitas tubuh. Tujuan penelitian ini adalah menentukan potensi glutamin dalam meningkatkan kemampuan sistem imun terhadap infeksi P. aeruginosa. Penelitian eksperimental dengan post test only control group design telah dilakukan terhadap 24 ekor mencit usia 6-8 minggu dengan berat 30 gr. Mencit dibagi ke dalam dua kelompok, yaitu kontrol (K) danperlakuan (P) yang diberi glutamin dengan dosis 30 mg/kg/hari selama 14 hari. Isolasi makrofag peritoneum mencit dilakukan pada hari ke-15 dan dilakukan uji fagositosis menggunakan latex dan bakteri P. aeruginosa. Pengamatan dilakukan terhadap persentase makrofag aktif terhadap latex dan P. aeruginosa. Hasil pengamatan dan analisisstatistik menggunakan metode t-test menunjukkan adanya perbedaan yang signifikan antara kontrol dan perlakuan (p<0.05). Persentase makrofag aktif terhadap latex adalah 0,63 ± 0,058 (K) dan 0,84 ± 0,04 (P), sedangkan terhadap P. aeruginosa adalah 0,56± 0,07 (K) dan 0,80± 0,03 (P). Terlihat bahwa angka persentase fagositosis terhadap P.aeruginosa lebih kecil karena adanya kemampuan bakteri untuk menghadapi makrofag dibandingkan latex. Kesimpulan yang diperoleh dari penelitian ini adalah bahwa asam amino non-esensial glutamin memiliki pengaruh untuk meningkatkan kemampuan sistem imun tubuh. Kata kunci: glutamin, fagositosis makrofag, Pseudomonas aeruginosa Abstract Pseudomonas aeruginosa is the most common cause of bacterial infections that are resistant to antibiotics. Glutamine is an amino acid  in the body that able to modulate the body's immune function. The objective of this study was to determine the potential of glutamine in enhancing the ability of the immune system against infection of P.aeruginosa. Experimental research with post test only control group design was conducted on 24 male minutes 6-8 weeks of age weighing 30 grams. Mice were divided into two groups: control (K) and treatment (P) are given glutamine at a dose of 30 mg / kg / day for 14 days. Isolation of peritoneal macrophages of mice performed on day-15 and testedusing latex and bacterial phagocytosis of P. aeruginosa. Observations were made of the percentage of activated macrophages toward latex and P. aeruginosa. The observation result and statistical analysis using t -test showed a significant difference between the control and treatment (p <0.05). The percentage of active macrophages to latex was0.63 ± 0.058 (K) and 0.84 ± 0.04 (P), while to P. aeruginosa is 0.56 ± 0.07 (K) and 0.80 ± 0.03 (P). That seein it percentage of phagocytosis against P. aeruginosa smaller than compared to latex. Because of the ability of bacteria to confront macrophages. The conclusion from this study is a non-essensial amino acid glutamine has the effect to increase the ability of the body's immune system.

This research studied the interrelationship between the immune and oxidative-antioxidant systems in a group of individuals who had lived for a long time in areas contaminated with radionuclides after the Chernobyl catastrophe and as a result experienced prolonged exposure to small doses of ionizing radiation. We have examined a group of 100 students aged 18–24, where 50 of them formed the control group and the remaining 50 belonged to the experimental group as they arrived from the territories of enhanced radioecological control (IV radiation zone, density of soil contamination by isotope 137Cs 3.7 x 104 – 18.5 x 104 Bq/m2). Here we determined the level of cortisol, leukocytes and their populations, the levels of lymphocyte subpopulations with phenotypes CD3+, CD5+, CD4+, CD8+, CD16+, CD72+, immunoregulatory index CD4+/CD8+, indicators of phagocytic activity of neutrophils and monocytes, IgG (H), IgM (H), IgA (H), malondialdehyde (MDA), ceruloplasmin (CP), transferrin (Tr), sulfhydryl (SH); and also calculated the oxidative stress index (OSI). We performed the analysis twice: in the absence/presence of additional emotional stress such as an examination session. The studies showed an increase in the oxidative stress index in the group examined from the experimental cluster, especially in terms of emotional stress. At the same time, the neutrophil level increased, but phagocytic activity of neutrophils and monocytes, the relative and absolute number of lymphocytes with phenotypes CD3+, CD5+, CD4+, CD4+/CD8+, and IgG levels decreased. Consequently we revealed the negative correlation between the indexes of oxidative stress in the group of examined (the oxidative stress index (ISO)/the level of malonic dialdehyde (MDA)) and the parameters of phagocytic activity of monocytes, the immunoregulatory index CD4+/CD8+, and the number of lymphocytes with the CD16+ phenotype. In this study we demonstrated the decrease in the participation of ceruloplasmin (CP) as an important antioxidant factor in maintaining the immune homeostasis of the group examined from radiation-contaminated areas compared with control group. The evidence of this is the lack of reliable correlation between ceruloplasmin level and immune system parameters. Moreover we found that radiation-induced intensification of oxidative processes in the experimental group grew in conditions of additional stresses of an emotional nature. Besides, it was accompanied by a significant correlation in the level of oxidative stress and phagocytic activity parameters. Reducing phagocytic activity and the CD4+/CD8+ index on the background of oxidative stress increase can be considered as a sign of immune system ageing, while a decrease in the number of lymphocytes with the CD16+ phenotype is a sign of antitumor defense inhibition. Thus, we draw the conclusion that the inhabitants of the territories of strengthened radioecological control, undergoing exposure to small doses of ionizing radiation from birth, show a significant imbalance of redox homeostasis, which creates the preconditions for immunoreactivity pathology development at the level of both innate and acquired immunity.
