Comparative characteristics of different methods of treatment of microsporia

Microsporia is the most common disease of fungal etiology, most often caused by the pathogen Microsporum canis. Treatment of this disease requires a comprehensive approach, because the disease is dangerous to humans. Therefore, in the treatment of microspores, it is important not only to carry out therapeutic measures, but also to prevent the spread of the pathogen of the fungus in the environment and increase the immune status of the organism in the fight against infection. The main source of infection is cats. In order to determine the effectiveness of treatment of microsporia by various methods, studied of the blood and skin of guinea pigs infected with the pathogen M. canis. Sick animals were divided into three groups. The first group was treated with the systemic antifungal itraconazole and topical treatment with a solution of clotrimazole. Treatment of the second group was performed with a topical antifungal agent (1% solution of clotrimazole) with vaccination with the antifungal vaccine “Vakderm”. For the third group, the developed drugs were used – antifungal agent “Micromar” and immunostimulant “Biogluk”. During treatment, hematological and immunological blood researches and histological skin examinations were performed. During treatment with antifungal drugs (itraconazole and clotrimazole) the number of leukocytes decreases from 11.13 ± 0.72 to 7.13 ± 0.22, rod-shaped neutrophils from 15.76 ± 1.29 to 5.50 ± 0.76, and segmental increases from 12.17 ± 1.47 to 24.17 ± 2.27, decreases ESR from 5.67 ± 0.67 to 2.33 ± 0.42, which occurs when inhibiting the inflammatory response of the organism to infection. Thrombocytopenia (from 231.17 ± 7.60 to 184.33 ± 7.65) and eosinophilia (from 2.70 ± 0.73 to 7.33 ± 1.33) are also noted. There is a slight increase in T-helpers and a decrease in T-suppressors. Histologically, the infiltration of the dermis by histiocytes and eosinophils under skin persists. In the treatment of microsporia by treatment with 1 % solution of clotrimazole and vaccination with the vaccine “Vakderm” the results of studies showed that the number of leukocytes decreases from 11.13 ± 0.72 to 5.35 ± 0.31 (P < 0.01), rod-shaped neutrophils from 15.76 ± 1.29 to 7.67 ± 0.56, and segmental increases from 12.17 ± 1.47 to 22.17 ± 0.91 (P < 0.001), decreases). The number of T-helpers is increasing. The histological picture on day 7 is characterized by hyperkeratosis, and on day 14 the hyperemia of the basal layer of the epidermis persists. When using the antifungal drug “Micromar” and immunostimulant “Biogluk” the results of studies showed that the number of leukocytes decreases from 11.13 ± 0.72 to 6.95 ± 0.10, rod-shaped neutrophils from 15.76 ± 1.29 to 6.17 ± 0.65, and segmental increases from 12.17 ± 1.47 to 22.00 ± 0.86, decreases ESR from 5.67 ± 0.67 to 2.17 ± 0.31. Increases the number of T-helpers and the number of natural killers and T-suppressors is gradually decreasing. Histological changes are presented in the form of dilation of blood vessels and visualization of single erythrocytes in the dermis on day 14 of treatment.

Effect of laser therapy on the immune status of patients with chronic salpingoophoritis of chlamidial etiology

Aim. Justify the use of low-frequency laser radiation (LFLR) treating chronic salpingoophoritis of chlamydial etiology, taking into account the assessment of the immune status.Material and methods. The study included 110 women, of which 80 women had chronic salpingo-oophoritis of chlamydial etiology, and 30 were practically healthy. In addition to conventional methods, patients underwent examinations like immunological analysis, ultrasound examination of the pelvic organs, enzyme-linked immunosorbent assay (ELISA), polymerase chain reaction (PCR) analysis.Results and discussion. When comparing changes in the immune status in patients after LFLR and who underwent traditional therapy in the group of patients with sexually transmitted infections (STIs), there was a slight increase in the number of T-lymphocytes and T-helpers, as well as a decrease in the number of T-suppressors. Also, in these patients, there is a slight decrease in the number of IgA and IgM against the background of an increase in IgG and an increase in the phagocytic activity of neutrophils. In patients with traditional therapy, the above-described changes persisted, while an aggravation of the disturbed T-cell balance was observed.Conclusions. Thus, according to the results of a comparative analysis of the obtained data on changes in the immune status in patients with chronic salpingo-oophoritis after the use of laser therapy, a statistically significant increase in the number of T-lymphocytes, an increase in subpopulations including T-helpers, a decrease in the number of T-suppressors, an increase in immunoglobulin G and an increase in phagocytic activity of neutrophils was observed.

Physiotherapy Complex for the Treatment of Children with Somatoform Dysfunction, Often Suffering from Recurrent Infection

The aim. to optimize the treatment of children with ADHD who often suffer from recurrent infections by justifying the effectiveness of a therapeutic and physiotherapy complex that includes a BOS-bioacoustic effect on the head area and NILI on the projection of the cubital area and thymus. Method of research. In children (140 people) with a verified diagnosis of ADHD, often suffering from recurrent infection, humoral-cellular immunity indicators (immunoglobulins: IgA; IgG; IgM); T-and B-lymphocytes; cytokines) were studied in the dynamics of the use of therapeutic measures. Depending on the applied physiotherapy method of treatment, the children were divided into 3 groups: the 1st group-received NILI on the projection of the cubital area and thymus, the 2nd – received BOS-bioacoustic effect on the head area, the 3rd – developed physiotherapy complex, including BOS-bioacoustic effect on the head area and NILI on the projection of the cubital area and thymus. Conclusion. the developed physiotherapy complex, including BOS-bioacoustic effect on the head area and NILI on the projection of the cubital area and thymus, can be considered as a therapeutic and preventive model of respiratory viral attacks in children with SSDVNS, since it reduces the number of recurrent viral attacks by 3.7 times, correcting the activity of circulating cytokines, T-lymphocytes (CD3+), T-helpers (CD4+) and T-suppressors (CD8+) in the population white blood cells.

Influence of cadmium on the cellular part of the immune system of young cattle

The article presents the results of research on the effect of cadmium load on the body of young cattle. The negative effect of Cadmium on the liver causes a wide range of pathological changes at different levels of its organization. The impact of heavy metals on the immune system is particularly significant, because it performs a leading role in maintaining health and is recognized as one of the most sensitive to adverse factors, even in relatively low concentrations. The aim of the study was to investigate the influence of cadmium on the cellular part of the immune system of young cattle. The research was carried out on 10 bulls of six months of age, Ukrainian black-and-white dairy breed, which were formed into 2 groups of 5 animals each: control and experimental. The bulls of the control group were on a normal diet. Animals of the experimental group were administered cadmium chloride at a dose of 0.04 mg/kg body weight of the animal. It was found that feeding bulls with a diet of cadmium chloride, the number of B-lymphocytes on the 5th day of the experiment was 17.54 ± 0.95 %. The lowest number of B-lymphocytes was on the 20th day of testing – 15.12 ± 0.37 %. The study of the number of T-lymphocytes shows that at the beginning of analysis the number of T-lymphocytes in the blood of animals of the control and experimental groups ranged from 40.70 ± 3.62 and 40.85 ± 2.54 %. Subsequently, the number of T-lymphocytes in the blood of the experimental group began to decline. The lowest number of T-lymphocytes was in the experimental group of animals on the 20th day of the research, compared with the control group, this figure decreased by 3.63 %. The state of immunity of animals under cadmium load significantly depends on the ratio of T-helpers to T-suppressors. It was found that the immunoregulatory index of blood of bulls of the experimental group probably decreased from 10 days of the research. The number of T-helper lymphocytes in the blood of the experimental group of bulls under cadmium loading is probably reduced by 15, 20 and 30 days of testing. A probable increase in the number of T-suppressors was noted in the bull's blood of the experimental group on the 20th day of the research. Immunoglobulins of different classes are crucial among bull’s serum proteins under cadmium loading. The concentration of immunoglobulins in the blood under cadmium load decreased by 15.9 % relative to the control group on the 20th day of analysis.

CLINICAL EFFECTS OF HUMAN IMMUNOGLOBULIN ADMINISTRATION IN WOMEN WITH RHESUS SENSITIZATION AT THE PRE-GRAVID STAGE

The aim of the study – to evaluate changes in cellular immunity in rhesus-sensitized women in response to IVIG administration and the prognostic effectiveness of a method for the prevention of isoimmunization in the next pregnancy. Materials and Methods. The study was performed on the basis of City Maternity Hospital No. 7" (Odesa) in 2014–2019. 37 rhesus-sensitized women were randomly splited in two clinical groups: main clinical group (n=19) where patients received human immunoglobulin for intravenous administration, and control group (n=18) where patients did not receive IVIG. Results and Discussion. The state of cellular immunity in rhesus-sensitized women is characterized by a moderate decrease in the absolute and relative indices of T-lymphocytes while increasing the number of B-lymphocytes. The NK cell population did not differ from the control group. When analyzing subpopulations of T-lymphocytes, it can be concluded that the number of T-helper cells is increased and the number of T-suppressors is proportionally reduced. These changes explain the increase in the number of B-lymphocytes as a result of increasing antigenic load on cell receptors. In the group of women who received IVIG therapy, the ratio of chances of normalization of cellular immunity was 18.41 (95 % CI 2.62–166.74), T-helper – 14.93 (95 % CI) 2.45–107.8), T-suppressors – 14.57 (95 % CI 2.13 –127.57) and B-lymphocytes – 31.87 (95 % CI 4.1–333.41). According to the ROC analysis, the quality of the statistical model of IVIG application corresponds to AUC = 0.843 (95 % CI 0.689–0.941) According to the ROC analysis, the level of β-lymphocytes in the compared AUC groups = 0.58 (95 % CI 0.405–0.742).

Correction of cellular immunity with biferon-C in piglets in case of specific prevention of circovirosis and mycoplasmosis

The results of studying the effect of biferon-C containing recombinant porcine interferons -alpha and -gamma on cellular nonspecific and adaptive immunity in piglets in case of specific prevention of circovirosis and mycoplasmosis are presented. The corrective effect of the drug on cellular immunity was stated, manifested by an increase in the absorption and functional and metabolic activity of phagocytes, the relative and absolute number of T- and B-lymphocytes, T-cells with helper activity and a lower formation of the level of T-suppressors, an increase in the T-helpers/T-suppressors ratio.

Dynamics of Cellular Factors of the Immune System of Arctic Foxes (Vulpes lagopus) on the Background of Mixtinvasion

The article presents data on the dynamics of cellular immune system factors of the arctic foxes (Vulpes lagopus) while being affected by mixtinvasion of protozoa (Isospora vulpina) and helminth (Toxascaris leonina). The changes in the blood cell composition, in particular those responsible for the body’s immunity and immune status, reflect the pathological effect of the endoparasites on the animal’s body. The development of the invasive process during mixtinvasions causes and is accompanied by a decrease in the level of nonspecific resistance of the host organism. In addition, a significant process of inhibition of the lysozyme complementary activity in the blood serum and the development of secondary immunodeficiencies is observed. The aim of our work was to study the development of the pathological process in arctic foxes, caused by previously detected mixtinvasion by eimeriidoses and helminthiases, as well as to identify dynamical patterns of the immune system cellular factors. Intravital diagnostics of parasitoses was carried out by means of coproscopic studies with the help of conventional flotation methods. 127 arctic foxes participated in the experiment. Among them individuals with double invasion, an invasion with both protozoa (placeI. vulpina) and helminth (T. leonina), were selected for the experiment. Healthy animals served as the control group. Arctic foxes which took part in the experiment were divided into three groups of 10 animals each. Groups were formed by the method of balanced analogous groups. Evaluation of the T-system of immunity was carried out by the method of spontaneous rosetting according to Jondal (1972). Isolation of lymphocytes by the method of A. Boyum (1968), B-lymphocytes were determined by the method of E. Mendes (1973), theophylline-resistant and theophylline-sensitive T-lymphocytes were determined using the method of S. Limatibul et.al. (1978). The immunoregulation index was calculated by the ratio of T-helpers to T-suppressors. During the experiment, it was found that in infected animals the total number of lymphocytes was significantly 10.2 % higher than in animals in the control group, however, there was a tendency to a sharp decrease in the total number of lymphocytes in patients with I. vulpina + T. leonina. The T-helper dynamics in infected foxes was 18.9 ± 0.9 (P≤0.05), which is 21.9 % less than in the control – 24.2 ± 0.6 (P≤0, 05). The dynamics of T-suppressors turned out to be directly opposite to the dynamics of the T-helpers. The dynamics of B-lymphocytes in the 2nd group turned out to be 1.76 times higher than in animals from the control. In the 3rd group same indicator was comparable with the control values of 2.9 ± 0.3, against 2.5 ± 0.4 in the control group. The study showed that mixtinvasion with placeI. vulpina + T. leonina leads to immunosuppression in the arctic foxes. Interestingly the specific therapy did not straighten the immune state of the animals, but on the contrary it became more pronounced, which suggests that antiparasitic drugs have an immunosuppressive nature on the body of arctic foxes as evidenced by violations of the parameters of the body’s natural resistance, the content of T-E-ROCK lymphocytes.

Dynamics of blood immunological indicators in the period of the reproductive cycle under different technologies of keeping

The obtained results of search on the influence of technology and conditions of sows holding of different physiological states on immunological parameters indicate that that the content of T-lymphocytes in the blank and sows of the first half of fertility in both farms was very high and exceeded the upper limit of physiological norm by 1–3% on average. However, with the onset of the second half of fertility and lactation in sows, a decrease in its level, fluctuating within the limits of the physiological norm (49.12%–51.37%), was noted. The content of T-helper cells in sows of all physiological groups of both farms was within the limits of the physiological norm. The difference between the indicators was the highest in sows of the second half of fertility – 8%, in favor of sows from the farm of the Staryi Sambir district. In other groups of sows the T-helper's content varied from 0.12% to 1.7%, with the overwhelming majority in favor of sows from the Zolochiv district. In fact, the same percentages were the indexes of the contents of T-suppressors of blank and sows of the first half of the fertility of both farms. In the sows of the second half of fertility, the difference between the indicators of this population of lymphocytes was 3.37%, the predominantly higher rate was observed in sows from the farm of the Zolochiv district. In lactating sows, the difference in rates was significantly lower, only 0.88%, with a tendency for growth in animals from the Staryi Sambir district. An analysis of the level of humoral protection of the sow's blood of reproduction period showed, that in all physiological groups, except lactating, the content of B-lymphocytes was on average 0.38% – 0.95% higher was in sows from the farm of Zolochiv district. In lactating animals, the level of these lymphocytes was 3.75% higher in females from the economy of the Staryi Sambir district. The immunoregulatory index in almost all animal groups exceeded the upper limit of the physiological norm by 0.11%–0.48%. The exception was only sows of the second half of fertility from the farm of Zolochiv district and lactating sows from the economy of the Staryi Sambir district, where the index of IRI was at the level of the upper limit of the physiological norm, but did not exceed it. The phagocytic activity of neutrophils ranged from 38.68% to 63.05% and did not exceed the physiological norm. The index of phagocytic number in all groups of sows corresponded to physiological norms. Exceptions were sows from the economy of the Staryi Sambir district, the indicator corresponded to the value of 3.44, which is 0.56 less than the lower limit of physiological norm.

Effect of aquacitrate of micro elements on indices of nonspecific resistance and cellular immunity in chicken broilers

The article presents data on the influence of the complex of micro elements (Fe, Cu, Zn, Co, Mn) in the form of aquacitrate on the indices of non-specific and cellular immunity in chicken broilers. The poultry received a fodder, balanced by nutrients, according to its type, age and productivity. Control group of chickens were added standard mineral premix (SP) from inorganic compounds of bioelements. Broilers of experimental groups were given water with a complex mineral additive of aquacitrates. In particular, the chickens of the first experimental group – in the amount corresponding to their content in the standard premix (SP), and the 2nd, 3rd, 4th and 5th experimental groups – in the amount equal to 3/4, 1/2, 1/4 and 1/10 of the content of mineral elements in the standard premix. It was found that bactericidal and lysozyme activity of blood serum (BASB and LASB) were the highest in broiler chickens of the third and fourth experimental groups and exceeded the control values by 5.7 and 5.3%, respectively. In the bird of the second and fifth groups, the studied indicators were closer to the ones in control. However, in the chickens of the group D1, giving them the highest studied dose of aquacitrate of micor elements, the values of BASB and LASB tended to decrease. Concerning the level of CIC in serum, it was the highest in the chickens of the second, third and fourth groups, the lowest in the group D1. A similar pattern is also characteristic for phagocytic activity of pseudoiesinophils (PhA). The bite of half and even the quaternary amount of citrates of micro elements, compared with the amount of bioelements in inorganic form, provided an increase, compared to control, of PhA. At such a dose of micro elements in the nanoform in the blood of broilers, the number of T-total and T-active lymphocytes increased, including T-heeler cells and decreased the relative number of T-suppressors. The bird of the first experimental group was characterized by a decrease in the percentage of T-heeler against the background of a slight increase of T-suppressors. Thus, the results of studies of indices of nonspecific and cellular immunity suggest that micor elements in the nanodisperse form, due to better bioavailability and high bioactivity, have a positive effect on the formation and development of the immune system in broiler chickens at a dose corresponding to 25 and 50%, from recommended quantity of biometals in the standard premix.

CHANGES IN THE CELLULAR IMMUNE PROTECTION OF ORGANISM IN THE PROCESS OF CHRONIZATION OF EXPERIMENTAL BACTERIAL-IMMUNE PERIODONTITIS

One of the important factors that leads to damage of structures of the periodontal complex and leads to the formation of inflammatory process of varying degrees is the disruption of immunological processes. The aim of the study was to clarify the pathogenetic role of cellular adaptive immunity in the process of formation of chronic inflammatory reaction in the late period of the experimental bacterial-immune periodontitis. The study was conducted on white, non-breeding, clinically healthy male rats. Experimental bacterial-immune periodontitis in experimental animals was caused by insertion into the tissues of the periodontal complex a mixture of microorganisms diluted with egg protein. The obtained digital data was statistically processed using parametric and nonparametric statistical methods. The article represents the results of research on the parameters of cellular immune defense, determined by the relative number of CD3+ (common T-lymphocytes), CD4+ (T-helpers), CD8+ (cytotoxic cells, T-killers), CD19+ (B-lymphocytes), CD16+ (natural killers, NK-cell) and immunoregulatory index (CD4+ / CD8+) in intact animals and on the 30th day of experimental bacterial-immune periodontitis development. It was established that the nature of the course of experimental inflammation in the tissues of the periodontal complex depended on changes in the cellular immune status, accompanied by a decrease of the content of common mature T-lymphocytes (CD3+) in the blood of animals with experimental bacterial-immune periodontitis on the 30th day of the study. In the process of the development of the experimental bacterial-immune periodontitis there was a decrease of the content of T-lymphocytes-helper (CD4+) in the blood of animals and on the 30th day of the study an increase in T-suppressors (CD8+), an increase in the content of natural killers (CD16+) and a decrease in the relative content of B-lymphocytes (CD19+). The immunoregulatory index (CD4+ / СD8+) decreased in comparison with this indicator of a group of intact animals. In rats with bacterial-immune periodontitis, an immunosuppressive state developed in the late period of the inflammatory reaction due to both T-helper cells and cytotoxic T-suppressors / killers. These changes can be considered as signs of formation of the chronic course of the inflammatory process in the tissues of periodontal complex.
