Immune system of reproductive organs of animals is represented by a number of cellular and humoral protection factors. Recently, the attention of scientists was attracted by the role of immunocompetent cells, which integrally provide immune homeostasis at all stages of the reproductive function. The purpose of the work was to study the cellular factors of immune defense of mucous membranes of genital organs of dogs and cats. The cytological composition and determination of immunological parameters of vaginal microscope slide were determined by patented methods. Local immunity was determined by the parameters of extracellular protection mechanisms, which consisted in the study of the Oxygen-dependent potential of neutrophil granulocytes (NBT-test) and their ability to form extracellular traps (NETs). Our studies have found that in different stages of the sexual cycle in beach and cats, along with cytological changes in epithelial cells, changes occur in phagocytic protection. In particular, in the post-infusion period there was an increase in the number of intermediate and basal epithelial cells on the surface of which were adhered microorganisms. Along with epithelial cells, activated phagocytes were grouped. Neutrophils showed cytochemical reactivity in the NBT-test, and also formed NETs. At the same time, activated phagocytes absorbed microorganisms, and some epithelial cells formed specific cytoplasmic inclusions, which obviously also has an important role in the antimicrobial immunity of the mucosa. Some neutrophilic granulocytes were in a state of apoptosis. During the sexual cycle in the organism of dogs and cats there are morphology and functional changes in the genital organs, which was accompanied by a change in the cytological picture of vaginal microscope slides. It was established that the antimicrobial protection system plays an important role in the neutrophilic granulocytes, the functional activity of which also has a change. The main mechanisms of extracellular antimicrobial protection of microphages are realized with the involvement of Oxygen species in the excretion system of active forms and the formation of neutrophilic extracellular traps. Epithelial cells are also involved in the formation of immune homeostasis of genital mucous membranes.

Infectious diseases associated with diseases of ENT organs are quite common. Therefore, this problem requires detailed study. The main goal of the work is to characterize the immunological NBT test – the index of phagocytic and metabolic activity of neutrophilic granulocytes in cases of complications of ENT diseases. To achieve this goal and study the problem in detail, the authors used experimental methods. The experiment was conducted on 40 patients from 32 to 65 years. The authors found that during the eruptive phase of the disease, the percentage of NBT positive granulocytes and tetrazolium activity significantly increased and amounted to 30-40%, while the control group’s data were the following – the activity of the NBT test was 4.9-6.8%. It was also found that the NBT test in patients with otitic meningitis was 26-62%, while in all patients with serous meningitis, the level of the NBT test was low – 6-11.

Objective: Allergic rhinitis is a type 1 hypersensitivity reaction of immunoglobulin E in the rhino-ocular mucosa. This study was planned to demonstrate in patients with allergic rhinitis to evaluate changes in tear, nasal secretions, and blood osmolarity compared to healthy individuals. Method: Forty allergic rhinitis patients, 25 patients with acute upper respiratory tract infections, and 26 healthy participants were included in the study. Positive patients with allergic symptoms and skin prick test results were included in the allergic rhinitis group. Tear, nasal secretion, and blood osmolarity values were examined for the 3 groups. Result: In patients with allergic rhinitis, tear and nasal secretion osmolarity values were significantly higher in patients with acute upper respiratory tract infections and those of the healthy participants ( P = .001, P = .038). In blood osmolarity measurements, there was no statistical difference between the groups ( P = .489). In patients with allergic rhinitis, Schirmer test results were significantly shorter than patients who had acute upper respiratory tract infection and those of the healthy participants ( P = .001, P = .001). Patients with allergic rhinitis and acute upper respiratory tract infections had significantly shorter Schirmer test results than in healthy participants ( P = .001, P = .001). Conclusion: Tear osmolarity was increased in allergic rhinitis patients, and this was thought to lead to dry eye findings. In the presence of allergic rhinitis, nasal secretions were found more hyperosmolar than tears. Nasal secretion osmolarity was higher in allergic rhinitis patients than in patients with acute upper respiratory tract infections and control group.

Relevance: despite the available methods and medicines, rhinosinusitis occupies a leading place in the structure of diseases of the upper respiratory tract. Rhinosinusitis can be a consequence of respiratory viral infections, can be an independent nosological unit. In recent years, there has been a protracted course of rhinosinusitis with a long recovery period with chronic inflammation in the paranasal sinuses and nasal cavity. Purpose of the study: to analyze the validity and effectiveness of therapeutic approaches to the treatment of chronic rhinosinusitis using the Polydexa with phenylephrinum nasal spray with phenylephrine Materials and мethods: The study included 121 patients — 61 (50.41 %) women and 60 (49.59 %) men aged 25 to 50 years, a history of chronic rhinosinusitis in the stage of clinical exacerbation at the time of the study. All patients underwent: otorhinolaryngological examination, general clinical and radiological (radiography or computed / magnetic resonance imaging of the paranasal sinuses). Cytological examination of the detachable nasal cavity was carried out to study the calculation of the relative number of neutrophilic granulocytes, macrophages, epithelial cells, lymphocytes. Microbiological examination of the detachable nasal cavity and paranasal sinuses included the study of the qualitative and quantitative composition of pathogenic and opportunistic organisms on the surface of the nasal mucosa. Results: in patients with chronic rhinosinusitis in the stage of clinical exacerbation, an increase in the relative content of inflammatory elements was revealed in the nasal secretion against the background of the prevailing content of pathogenic staphylococci and streptococci. The use of topical preparations containing antibacterial components of a broad antimicrobial spectrum of action, dexamethasone, phenylephrine hydrochloride helps to relieve inflammation on the surface of the mucous membranes of the nasal cavity and paranasal sinuses. Conclusions: a method of treating chronic rhinosinusitis in the stage of clinical exacerbation using a combined preparation for topical application containing neomycin sulfate, polymyxin B sulfate, dexamethasone sodium metasulfobenzoate, phenylephrine hydrochloride has a pronounced anti-inflammatory, decongestant, antibacterial effect

Despite significant progress in the study of the qualitative and quantitative composition of microflora, there are many controversial issues related not only to diagnosis, but also to the treatment of dysbiotic disorders of the intestine. Dysbiotic disorders, characterized by a decrease in the qualitative and quantitative indicators of obligate and facultative microflora, can have a negative impact on human health. The doctor’s task is to restore the microbiocenosis of the gastrointestinal tract and the density of colonization of indigenous microflora, taking into account modern knowledge on this problem, presented in on-line training seminars.

The aim of the study is to investigate the functional properties of neutrophils in the blood and peritoneal exudate in patients with peritonitis. Materials and methods. The metabolic activity of neutrophils determined in patients with peritonitis and in patients of the control groups in the blood, peritoneal exudate and effusion of the abdominal wall on the 1–2 day of the postoperative period in the Sp and St test with nitro blue tetrazolium (NBT), as well as reserve indicator (RI) of metabolic activity. We studied the percentage of active neutrophils in the phagocytosis –PhI ( index) and the number of absorbed Candida albicans particles on average by one neutrophil –PhN(number). Results and their discussion.The peculiarities of the cellular factors of local protection decreased metabolic activity of neutrophils in the abdominal cavity in the Sp NBT test compared to blood neutrophils and an increased reserve during stimulation. For the comparisons which included the activity of neutrophils abdominal contents in patients with peritonitis versus in control established that neutrophils in the abdominal cavity with peritonitis have a reduced intensity of phagocytosis. Patients with pancreatic peritonitis have inverse correlations between the amount of NBT-positive blood NG in the SP NBT test and IR of blood NG and between the amount of NBT-positive blood NG in the Sp NST test and PhI of blood NG, while patients with abdominal peritonitis do not have correlations between indicators of innate defense of the body. Conclusions. Peritonitis was associated with functional disorders of NG. The leading areas of disorders are significant activation of metabolic processes of NG and inhibition of the phagocytic function of NG blood and peritoneal exudate. Patients with pancreatic peritonitis had inverse correlations between the indicators of the innate defense of the body, while patients with abdominal peritonitis did not have correlations.

Defects in the functioning of neutrophilic granulocytes (NG) are accompanied by various purulent-inflammatory diseases that have a persistent-relapsing course. The bactericidal activity of NG, the processes of intracellular and extracellular killing of bacteria, is directly dependent on their phenotypic features: the expression level of functionally significant membrane receptors CD64, CD16, CD32, CD11b triggering effector processes. It was shown that there are subsets of NG with different phenotypic characteristics and the course and outcome of infectious and inflammatory diseases directly depends on their usefulness. Despite the large amount of accumulated information, the question of the transformation of NG subpopulations phenotype during NG response formation in children with local purulent processes of soft tissues - a small purulent infection (SPI) remains poorly understood. Purpose: to evaluate the local and systemic effector function of neutrophilic granulocytes (phagocytosis, NET formation) with clarification of the phenotype of functionally significant CD64-CD16+CD32+CD11b+, CD64+CD16+CD32+CD11b+ and CD64-CD16+CD32-CD11b+ NG subpopulations in peripheral blood (PB) in children with SPI. Materials and methods. We evaluated the phagocytic function of NG in 60 PB samples of children 5-9 years old, on the 2-3rd day of acute purulent process, before surgery, in smears - prints taken from the local focus of purulent inflammation and 17 PB samples of conditionally healthy children. Also the ability to form NET was additionally determined in smears-prints in children with SPI. In parallel, in PB we evaluated:% NG simultaneously carrying CD64, CD16, CD32, CD11b receptors and their expression density (MFI) by flow cytometry (CYTOMICS FC500, Beckman Coulter, USA). Statistical data processing was performed in the Microsoft Exel 2016 and Stat Plus 2010 software packages. Nonparametric criteria were used: median (Me) and interquartile range (Q1; Q3), Mann-Whitney U-test and Wilcoxon test. Results . We found a significant increase in the content of the NG subpopulation with a negatively transformed phenotype CD64-CD16+CD32-CD11b+ with defects in the expression of CD64 and CD32 receptors, which is the cause of inadequate inclusion of NG in inflammatory processes, disruption of phagocytic activity at the systemic and local levels and the occurrence of SPI in children. The formation of NET in the first stage is necessary to supplement the effector function of NG in order to compensate for disorders of phagocytosis.

Increased NBT dye reduction test responsiveness of neutrophil leukocytes has been observed in 14 of 17 infants with acute viral respiratory syndromes. Syndromes studied included croup, bronchiolitis, and pneumonia and were caused by parainfluenza virus types 1, 2, and 3, respiratory syncytial virus, influenza A virus, and adenovirus 1. NBT test elevation occurred early in every case of bronchiolitis and viral pneumonia and was associated with infections by all groups of viruses. On the other hand, NBT test results were normal or near-normal in a majority of cases of upper airway disease such as croup.
