Topicality and demand of the subject of dissertation. Bronchial asthma (BA) is one of the most common and serious diseases, which in the world suffer from 3 to 12% of the child population of the globe. Proportion of adolescents with asthma, is one third of all children with this disease. High prevalence of asthma in the numbers of teenagers, characteristics of the disease, age-related aspects of the functioning of the endocrine and immune systems of teenagers that cause difficulties which arise in the course of the diagnostic process, highlight the need to find innovative approaches to diagnosis and treatment of this disease.
It is known that the key immune mechanisms in the pathogenesis of the vast majority of AD cases is real and indisputable fact. Currently, considerable interest to researchers involved in the pathogenesis of positions of allergic diseases, especially asthma, along with IL-4 and IL-13 causes a number of other (IL-6, IL-8, IL-10, IL-5, INF-a and INF-y) immunoregulatory cytokines.
Genetic predisposition plays an important role in the development of allergic diseases. Currently available data on the relationship with asthma and associated with disease symptoms polymorphism approximately 150 genes. Important role as the main contender for the predisposition to asthma gene is a gene encoding flchain of high affinity receptor IgE. Interaction elevated levels of antigen-specific IgE with FceRip plays a central role in the pathogenesis of allergic asthma. Particularly attractive candidate gene asthma is also one of the enzyme genes biotransformation - GSTirl, encoding glutathione S-transferase and л1 express almost exclusively in the pulmonary tissue. This gene is located at the locus 11 ql 3, for which repeatedly shown clutch with atopic symptoms. Accumulated in the literature say about the relationship of gene polymorphism FceRI, GSTnl with different allergic diseases.
From this perspective, the study of immunological and genetic mechanisms of the pathogenesis of this disease for the construction of rational treatment and prevention emphasizes the relevance of this thesis research.
From the earliest days of independence, the country has successfully implemented state programs aimed at reforming the health care system. As a result, the targeted implementation of organizational health and research activities aimed at effective diagnosis, prevention and treatment of asthma among adolescents, with some success in the treatment of this disease in the country. However, now the problem of early diagnosis and the development of effective programs for treatment and prevention among adolescents with asthma remain one of the most important issues of modern health care. This research work was carried out in the framework of the tasks set by the Resolution of the Cabinet of Ministers of the Republic of Uzbekistan "On additional measures to improve the health of women and the younger generation," dated 25.01.2002 for the №32. In this regard, the need to deepen the information received about the state of cellular and humoral immunity among adolescents, asking pathogenetic informative immunogcnctic studies in asthma arc one of the important criteria demand the dissertation topic.

Conclusion
1. Set the frequency of occurrence of the disease and the structure of "asthma" in the arid zone among teens. Said pathology is recorded in 9,6% of the population surveyed adolescents, while the disease is more common among females. In the structure of the disease prevails periodical exposure and mild persistent form.
2. Identified by clinical features of asthma among adolescents living in the arid zone, indicate a high frequency of lesions of the bronchial tree association with allergic processes in other organs and tissues: in 73,9% of the AR, 53,7% with AK. 16,6% with BA and 14% with urticaria/angiocdcma.
3. Found that in the study population of patients with asthma adolescence occur expressed disturbances of the immune status, manifested deficit indicators as cell (CD3‘, CD4+, CD8 , CD16+), and humoral immunity (CD19 , IgA, IgG, IgM) and activation markers (CD23+, CD95). The immune status of patients with asthma in young people, adolescence has distinctive features, the depth of detected violations immunoreactivity was most pronounced in the younger age group.
4. In patients with bronchial asthma in adolescence revealed distinct changes in cell-cell interactions in the immune system: a significant increase in the content of Th2-cclls secreted IL-6 is a regulator of maturation of antibodies and immunoglobulin production itself, and vice versa reducing regulator activity of Th 1-cell cytokine INF-y.
5. It was found that the contents of cytokines IL-6, INF-y and in the peripheral blood is in communication with one pathogenic disease. It is shown that the lowest level of INF-y production in the scrum is characteristic of allergic clinical pathogenic variant asthma in adolescence. Adolescents suffering from predominantly infectious form of asthma, there is a sharp trend towards increased production of IL-6 in peripheral blood.
6. Revealed that markers of increased risk of allergic forms of asthma in adolescents Uzbek ethnicity arc genotype FceRip-109T/T allele FceRip-109T, low-risk markers - FcsRip-109C/C and allele Fc£Rip-109C.

In the study of prophylactic efficacy of immunomodulators positive indicators prevailed in the group of patients receiving polioksidony, necessitating its inclusion in the priority scheme of integrated treatment and prevention of asthma in adolescents.
In modern abdominal surgery, one of the current areas for research continues to be the improvement of various options for plastic surgery of postoperative hernias. More than 2,100,000 operations for ventral hernia are performed annually in the world, and 42% of them are postoperative hernias. In recent years, there has been a clear trend toward the expanded use of various types of biological meshes in hernioplasty. “A pooled analysis of seven PCSTAR studies for incisional hernias using retromuscular mesh showed a hernia recurrence rate of 5.7%”[1]. The use of standard surgical interventions such as alloplasty in the onlay position does not solve the problem of early postoperative complications: seroma discharge, mesh migration, adhesive disease, high frequency of hernia recurrence, etc. At the same time, hernia repair with local tissue creates the problem of increased intra-abdominal pressure and late complications in the form of recurrent hernias. “An increase in postoperative intra-abdominal pressure leads to multiple organ failure, then abdominal compartment syndrome, and even death.” [2]. Currently, there is no consensus on the surgical approach for giant postoperative abdominal wall hernias, and therefore the need to continue to develop new technologies and improve There is no doubt about the tactics. In world practice, at present, the most relevant studies continue to be studies aimed at studying the morphological and functional aspects of recurrent postoperative ventral hernias; electron microscopy reveals ultrastructural destructive changes in skin cells, aponeurosis and muscles, which indicates morphofunctional insufficiency of abdominal wall tissues; issues of cell engineering are discussed new innovative materials, experimental studies are being carried out on animals testing the biotechnical properties, texture and elasticity of new polymers, research is being conducted on open approaches with division of the posterior component with the release of the transverse abdominis muscle and a retrograde mesh, robotic operations have begun. Modern aspects of the development of domestic healthcare include many measures aimed at improving the results of treatment of patients with postoperative ventral hernias and associated pathological conditions through the introduction of modern principles of intensive care and surgical tactics. The development strategy of New Uzbekistan for 2022-2026 in seven priority areas includes tasks to improve the quality of provision of qualified medical services to the population[3]. The implementation of these tasks, including by optimizing tactical and technical approaches to the choice of hernioplasty method, as well as the development of methods for the prevention of purulent-inflammatory complications in the field of alloplastic material, is one of the current areas of abdominal surgery and medicine in general, due to the high medical and social the significance of this pathology.
This dissertation research to a certain extent serves to fulfill the tasks approved by the Decree of the President of the Republic of Uzbekistan “On comprehensive measures to radically improve the healthcare system of the Republic of Uzbekistan” No. UP-5590 dated December 17, 2018, the Resolutions of the President of the Republic of Uzbekistan “On measures to transform the surgical service, improving the quality and expanding the scale of surgical operations in the regions" for No. PP-5254 dated October 4, 2021 and "On additional measures to ensure public health by further increasing the efficiency of medical prevention work" for No. PP-4891 dated November 12, 2020, and as well as other regulatory documents adopted in this area. Compliance of the research with the priority directions of development of science and technology of the republic. The dissertation research was carried out in accordance with the priority direction of development of science and technology of the VI Republic “Medicine and Pharmacology”. Review of foreign scientific research on the topic of the dissertation.[4] Research work aimed at improving the quality of therapeutic and preventive care for patients with ventral hernias, carried out by many leading scientific centers and higher educational institutions in the world, including the Department of Surgical and Perioperative Sciences, Umeå University, Umeå (Sweden), Department of Surgery, Kingston General Hospital, 76 Stuart Street, Kingston (Sweden). nada), Department of Surgery, Helsinki University Hospital, Helsinki ( Finland), Service de chirurgie digestive et oncologique, CHU d'Amiens (France), Department of Biostatistics and Epidemiology, University of Oklahoma Health Sciences Center, Tulsa (USA), Department of Surgery, Howard University College of Medicine, Washington (USA) , Yong Loo Lin School of Medicine, National University of Singapore (Singapore), Department of Surgery, Michigan Medicine, Ann Arbor, MI, USA; University of Calgary, Calgary (Canada), Division of Plastic Surgery, Perelman School of Medicine at the University of Pennsylvania, University of Pennsylvania Health System, Philadelphia (USA), Brigham and Women's/Faulkner Hospital, Harvard Medical School, Boston (USA) , Department of Surgical Sciences, Uppsala University Hospital, Uppsala (Sweden), Department of Surgery, University of Texas Health Sciences Center at Houston, Houston (USA), Department of Surgery, Erasmus University Medical Center Rotterdam, Rotterdam (Netherlands), Department of Preventive Medicine and Public Health, Faculty of Medicine, Fukuoka University, Fukuoka (Japan), National Medical Research Center for Surgery named after A.V.

Vakhidov (Uzbekistan).
As a result of studies conducted around the world to increase the effectiveness of alloplasty for postoperative ventral hernias and reduce the risk of complications in the postoperative period, a number of scientific results were obtained, including: it was determined that patients who underwent reconstruction of the abdominal wall have an increased risk of postoperative respiratory failure, understanding the epidemiology of this complication can improve prevention (the Division of Plastic and Reconstructive Surgery, Department of Surgery, Oregon Health & Science University, USA); It has been proven that the larger the hernia, the higher the risk of early surgical complications, including such as respiratory decompensation, since hernias often increase in size over time, delaying surgery can lead to an increase in the size of the hernia and, therefore, a greater risk of complications (CentreforDigestiveDiseases, KarolinskaUniversityHospital, Stockholm, Sweden); it has been shown that the ratio of the hernia volume to the volume of the abdominal cavity <20% is an independent factor in tension-free closure, which justifies the interest in preoperative volumetry to adapt the tactics of surgical care (Servicedechirurgiegénérale, digestiveetendocrinienne, CHU LyonSud, HospicescivilsdeLyon, France); It has been determined that in patients undergoing elective laparoscopic hernia repair, predictors of mortality are older age and certain concomitant diseases: congestive heart failure, pulmonary circulatory disorders, coagulopathy, liver disease, metastatic cancer, neurological disorders and paralysis (Department of Surgery, College of Medicine, University of Oklahoma, Tulsa , USA); Older age, ascites, preoperative renal and pulmonary insufficiency have been found to be independent predictors of 30-day mortality, and in the presence of these risk factors, conservative treatment should be seriously considered (Department of Surgery, University of Kentucky College of Medicine, Lexington, USA); The American College of Surgeons (ACS) Universal Surgical Risk Calculator has been shown to accurately predict thirty-day outcomes, including major complications: venous thromboembolism, medical morbidity, surgical site infection, unplanned reoperation, mortality, and length of hospital stay (Department of Plastic Surgery, Brown University and Rhode Island Hospital, Providence, USA). At the present time in the world, the most relevant research in surgery continues to be the development of new methods of hernioplasty for large and giant ventral hernias, each of which has its own pros and cons depending on the complexity of implementation, the risk of postoperative complications and relapse, large randomized clinical trials are being conducted, comparing existing methods of traditional hernioplasty with laparoscopic access and robotic surgery, which has become increasingly widespread in the last 10 years, a search is being made for new synthetic and biological materials developed for the production and use of composite meshes that have the necessary strength and the ability to prevent fatal local complications in a contaminated environment. However, despite technical advances in this field, no modern hernia repair method or prosthesis meets all the requirements. One of the key problems is that existing synthetic endoprostheses do not have sufficient elasticity, resistance to infection, high mechanical strength and integrity over a long period of time. Further research into these clinical aspects will undoubtedly improve the current understanding of the capabilities of biocompatible endoprostheses and will make it possible to develop an optimal method for their placement during allohernioplasty. The degree of knowledge of the problem. The current period of development of abdominal surgery is characterized by an emphasis on the problems of the effectiveness of introducing new installation methods and techniques for attaching bioprostheses, options for various suture materials to determine the most promising directions for the development of these technologies [5]. Researchers led by BittnerR.[6] (2019) state that a giant postoperative abdominal wall hernia, the maximum diameter of which exceeds 12 cm or the ratio of the volume of the hernial sac to the abdominal cavity more than 20%, is difficult to treat, with a high recurrence rate and a large number of complications. One of the most challenging problems is that after the hernia contents return to the abdominal cavity, postoperative intra-abdominal pressure will increase, leading to multiple organ failure, then abdominal compartment syndrome (ACS), and even death. There is currently no agreement on the surgical approach for these giant incisional abdominal wall hernias. To prevent recurrences, some articles recommend placing the hernia mesh in the sublayer position and or linings (KirkpatrickAW.)[7]. According to CornetteB.[8], to prevent recurrence, it is recommended to place the hernia mesh in a sublayer or underlay position, and to achieve better mesh expansion, a component separation technique (CST) may be a suitable solution, but with a significant risk of complications and recurrence. JensenKK, et al. believe that truly successful giant hernia repair requires effective bridging or augmentation that will prevent recurrence with an acceptable risk of complications[9]. Another pressing issue in abdominal surgery is that patients with incisional hernias are extremely difficult to treat due to a number of factors including obesity, previous hernia repair, previous mesh placement, domain loss, and other variables.
The approach to patients with incisional hernias has changed significantly over the past 20 years due to both advances in mesh technology and surgical approaches. Key factors for successful outcome include modification of risk factors preoperatively, such as smoking cessation and weight loss, selection of mesh appropriate for the type of hernia and planned mesh location, and wide mesh coverage beyond the hernia defect. New techniques such as transabdominal muscle release and component separation with retrograde mesh placement and robotic approaches to abdominal wall hernia are increasingly being used in these patients[10]. Recent years have seen an increase in the number of biological meshes available for abdominal wall hernia repair. Biological meshes typically consist of materials obtained from humans, pigs, or cattle. The rationale for using biological meshes is that they can act as a scaffold for the growth of natural tissues. In addition, there are absorbable synthetic meshes that have properties similar to those of biological meshes, but with theoretically less risk because they are not derived from animal or human material. The choice of mesh for a ventral hernia depends on many factors, which include both the properties of the mesh and its location, for example, whether it should be placed intraperitoneally, preperitoneally, or retrorectus. BaierKF[11](2021) believes that the guiding principle should be to avoid placing uncoated polypropylene mesh in an intraperitoneal location where it may be in direct contact with internal organs. In addition, the type of hernia defect is another risk factor, such as whether the wound is clean or dirty, and whether the repair is performed with a bridge or abutment. Lightweight or biologic meshes to bridge the defect should be avoided due to increased recurrence rates. Holihan JL [12] (2016), Hodgkinson JD [13] (2018) believe that the principle of anatomical restoration to achieve a reliable, tension-free repair with reinforced mesh reduces the incidence of early postoperative complications and late recurrence of hernia compared with bridging mesh. The analysis of the literature concerning the theoretical aspects and clinical experience of using technologies for improving modern synthetic and biological prostheses that can provide a better plastic effect, as well as methods for preventing recurrence of ventral hernias, indicates that this is one of the priority areas in modern abdominal surgery. An unresolved issue remains the choice of the optimal endoprosthesis, which is highly effective and meets international standards for such properties as biological inertness and mechanical strength, as well as the method of positioning the mesh in relation to the layers of the abdominal wall. Considering that many of the allohernioplasty methods used today are not without drawbacks, the current direction is the development of new methods of repair for giant ventral hernias and methods for the prevention of postoperative complications in conditions of a contaminated wound, with justification of their effectiveness in a clinical experimental study. The connection between the dissertation research and the research plans of the research institution where the dissertation was completed. The dissertation research was carried out within the framework of the research work plan of the State Institution “RSNPMCH named after. acad. V. Vakhidov" under the project AL-422105574 "Development of new biocompatible mesh implants made of composite materials for reconstructive surgery of abdominal and diaphragmatic hernias" (2022-2024).
The purpose of the study is to improve the results of surgical treatment of large and giant postoperative ventral hernias by introducing new laser technologies and improving the tactical and technical aspects of surgical treatment. Objectives of the study: to study the structure of immediate complications after various types of prosthetic plastic surgery; to clarify the influence of obesity factors, primary or repeat hernioplasty on the incidence of immediate and long-term complications; to evaluate the role of the immediate complicated course of the postoperative period in the incidence of long-term complications of hernioplasty; to improve the technical aspects of alloplasty for large and giant postoperative ventral hernias (POVH); to improve the technique of photodynamic therapy (PDT) of the wound surface after prosthetic plastic surgery; to study in an experiment the effectiveness of using the proposed technique of alloplasty and PDT; evaluate the morphological features of the condition of tissues during prosthetic plastic surgery using the proposed method; in a comparative aspect, evaluate the clinical effectiveness of the proposed alloplasty options in the immediate and long-term periods. The object of the study was the results of allohernioplasty in 448 patients with extensive (large) and giant POVH, who were operated on at the surgical department of the 1st clinic of the Samarkand State Medical Institute in the period from 2012 to 2021, as well as experimental animals on which the effectiveness was assessed developed a technique for prosthetic repair of postoperative ventral hernias and applied the technique of photodynamic therapy.
The subject of the study is to analyze the effectiveness of the developed alloplasty of postoperative ventral hernias and intraoperative photodynamic therapy in abdominal surgery in experiments and in the clinic. Research methods. To achieve the goal of the study and solve the assigned problems, general clinical, instrumental, biotechnological, experimental, histomorphological, microbiological and statistical research methods were used. The scientific novelty of the study is as follows: it was established that the need for extensive tissue mobilization and, as a consequence, the intersection of lymphatic capillaries during implantation of the prosthesis in the onlay position, as well as the lack of sufficient resorption function of the hernial sac in the inlay position causes a high risk of the formation of clinically significant seromas; It was determined that with prosthetic hernioplasty, along with the volume of the defect, the type of plastic surgery and the degree of obesity, the most significant predictor of the risk of developing immediate complications is the factor of re-intervention in case of recurrent hernia with the presence of a “dormant infection” hidden in the remaining ligature granulomas or scar tissue; the structure and clinical features of the course of long-term complications of hernioplasty for giant and extensive hernias were clarified, taking into account the results of the immediate postoperative period, as well as the option of fixing the prosthesis, primary or repeated hernioplasty and the degree of obesity; the method of surgery for large hernias of the anterior abdominal wall has been improved, characterized by a combination of factors such as the formation of tension-free prosthetic repair, preservation of local resorptive function to prevent the development of fluid accumulations and reducing the risk of infection; the method of preventing the development or progression of wound infection during alloplasty of ventral hernias has been improved, aimed at enhancing the antibacterial effect and stimulating reparative activity through the photosensitizing and photodynamic effect of low-energy laser radiation; It was determined in an experimental model of prosthetic plastic surgery that the proposed method of fixing the prosthesis in combination with the use of the effect of photodynamic therapy through laser radiation helps to enhance reparative processes with a reduced risk of wound complications; It has been proven that all methods of antiseptic exposure and laser stimulation of the wound surface after prosthetic plastic surgery enhance preventive measures against the development of local infection, but are ineffective in the case of an already developed purulent-inflammatory process against the background of the use of alloplastic material. The practical results of the study are as follows: it has been determined that the implantation of synthetic materials for giant and extensive hernias is accompanied by a significant number of wound complications caused by both the surgical technique itself and the reaction of surrounding tissues to a foreign body, requiring improvement of tactical and technical approaches when performing hernioplasty; it was clarified that scar-degenerative changes in the tissues of the aponeurosis in giant and extensive hernias are a predisposing factor to the occurrence of post-prosthetic hernias, especially when implanting the prosthesis in the “inlay” position and, accordingly, require increasing the efficiency of their fixation and engraftment, as well as reducing the risk of developing local complications; it was determined based on the data of an experimental study that the proposed method of alloplasty for large ventral hernias makes it possible to achieve adequate reconstruction of the anterior abdominal wall, reduce the incidence of infection in the wound, and also use a smaller size of prosthetic material; it was determined that the proposed method of tension-free repair of large hernias of the anterior abdominal wall with strengthening of the aponeurosis with a mesh implant allows maintaining physiology, reducing the number of complications, shortening treatment time and reducing the risk of hernia recurrence; It has been determined that the proposed method for preventing the development or progression of wound infection during alloplasty of ventral hernias can reduce the frequency of suppuration, shorten the treatment time and the likelihood of relapse; It has been proven that the use of the proposed tactical and technical aspects of prosthetic repair for postoperative ventral hernias can reduce the incidence of specific complications, reduce rehabilitation time and the risk of hernia recurrence. Reliability of the research results. The reliability of the results is justified by the use of objective criteria for assessing the condition of patients, modern methods of diagnosis and treatment, the correct application of methodological approaches and sets of statistical analysis, methods for solving the problems discussed in the dissertation are based on modern scientific and practical concepts and approaches to the diagnosis and surgical treatment of patients with giant postoperative hernias. Scientific and practical significance of the research results. The results obtained make a significant contribution to the expansion of irradiation of existing ideas about the structure and clinical features of complications of hernioplasty for giant and extensive ventral hernias by identifying the morphological features of the development of a purulent-inflammatory process against the background of the use of alloplastic material, studying predictors of the risk of developing immediate complications, mechanisms for enhancing reparative processes through the use of an improved method of fixing the prosthesis in together using the effect of photodynamic therapy through laser radiation, which made it possible to enhance the antibacterial effect and improve the wound healing process. The practical significance of the study is that, based on the results obtained, the tactical and technical aspects of prosthetic hernioplasty have been optimized, the features of methods of antiseptic exposure and laser stimulation of the wound surface after prosthetic repair have been revealed, enhancing preventive measures for the development of local infection, and the method of surgery for large anterior abdominal hernias has been improved walls, characterized by a combination of factors such as the formation of tension-free prosthetic plasty, preservation of local resorptive function to prevent the development of fluid accumulations, thereby reducing the risk of developing postoperative complications, reducing the frequency of unsatisfactory results, length of hospitalization and the likelihood of relapse.

Relevance of the problem.Despite the great successes of angiosurgery, the problem of surgical treatment of abdominal aortic aneurysms does not lose its relevance. World health statistics records a steady increase in the incidence of abdominal aortic aneurysm (ABA). According to L.J. Melton et al. (1984) and L.K. Bickerstaff et al. (1984) in the USA the number of patients with abdominal aortic aneurysm has increased 7 times in 30 years since 1951. In England and Wales, according to F.G. Fowkers et al. (1989) for the same period revealed a 20-fold increase in abdominal aortic aneurysms in men and 11-fold in women. According to the results of multicentre screening studies ABA was detected in 8% of the examined (E.S. Vourvouri, 2001), and in the age group of 64-69 years ABA was detected in 5.7% of the examined, and in the age group of 75-81 years - in 8.9% (R.A.P. Skott et al., 2001). A similar trend is observed in other countries. Accordingly, mortality from ABA is also increasing - aneurysm rupture in a number of countries is one of the ten most frequent causes of death among elderly and senile people (F.A. Lederle et al., 1990)
Currently, planned aneurysm resection has become a recognised standard of radical treatment of ABA patients and the number of these operations is steadily increasing. For example, about 40,000 ABA resections are performed annually in the USA (J.J. Grange et al., 1997). In Sweden during the period from 1987-89 to 1993-95 the number of ABA operations increased 5 times and currently 10 operations per 100,000 population are performed (A.Hallin et al., 2001), although this is 1.5 - 2 times less than the required number. However, postoperative lethality is still quite high and makes 5-7% (A.V.Pokrovskiy et al., 1992; Y.V.Belov et al., 1992; V.V.Vakhidov et al., 1992; A.W. Bradbury et al. Bradbury et al., 1997; A.Hallin et al., 2001).
E.W. Steyeberg et al. (1995) summarised the data of literature on 17238 ABA resection operations and gave an average mortality of 6.8%.
Multicentre studies in five major hospitals in the Netherlands found that only 74% of patients underwent ABA resection without complications; 26% had some complications, 9% of which were severe and 4.1% of which were fatal (G.J. Akkersdijk et al., 1998). Similar results were obtained in the Canadian Cooperative Study (K.W. Johnston et al., 1990). It was established that the peculiarity of complications in the majority of patients was their systemic character (L.L. Lau et al, 2001) The course of the postoperative period is most often complicated by cardiac, respiratory, renal, cerebrovascular, as well as complications associated with thrombosis and bleeding (W.E. Lloyd et al., 1996; R.D. Sayers et al., 1997; J.D. Blankenstein et al., 1998; R. Ayari et al., 1998). Ayari et al., 2001)
The undisputed leadership, without doubt, belongs to cardiac complications, the incidence of which varies from 10% to 20%. Moreover, cardiac complications account for 50-70% of total mortality. Cerebrovascular complications, although not uncommon, account for no more than 1-1.5%, but their mortality reaches 40%. Complications associated with thromboses and haemorrhages in the perioperative period reach 2-5% (M.M.Reigel et al., 1987; K.W.Johnson et al., 1990; N.Franklin et al., 1993; A.A.Milne et al., 1994).
Certainly, a large number of complications after resection of abdominal aortic aneurysms is caused by the initial severity of patients' condition, however, many unresolved tactical and technical issues of patients' preparation for the operation, stage of performance in case of combined lesions of several vascular basins play a practically significant role. Adequate management of the operation itself and the immediate postoperative period is no less important, taking into account the possibility of such dreadful complications as thrombosis and embolism, cerebral and cardiac death. Until now there is no unified complex analysis of the results of treatment of uncomplicated abdominal aortic aneurysms and, accordingly, recommendations for the prevention of possible complications.
All this determined our aim and objectives of the study.
The aim of the study is to improve the results of surgical treatment of ABA by developing an effective system for determining the main risk factors of surgical treatment and optimal surgical tactics to prevent possible complications.
Scientific novelty.For the first time a complex analysis of indications and contraindications to surgical treatment of abdominal aortic aneurysms was carried out
The most significant concomitant pathology capable to lead to formidable complications and lethality during the intervention and in the nearest postoperative period was revealed. Adequate measures of their prevention and treatment were proposed.
The algorithm of surgical treatment tactics for patients with combined pathology of coronary arteries and aortic arch branch lesions was developed
The state of haemostasis system at all stages of reconstructive surgery on abdominal aorta, starting from skin incision to wound closure, was studied for the first time.
Conclusions:
1. The proposed original classification of ABA, based on mutual dependence on the etiology of the disease, localisation, concomitant diseases, clinic and its course, allows to determine the strategy of early diagnosis, to estimate the most significant risk factors, the stage of intervention in combined lesions of adjacent and distant vascular basins and, ultimately, to determine the ways to reduce complications and mortality in patients with ABA.
2. The most informative methods of ABA diagnostics are duplex scanning and computed tomography. Non-invasive diagnostics capabilities are enough to determine the aneurysm size, its relation to the renal arteries, as well as to find out the state of visceral branches and aortic bifurcation. Abdominal aortography is indicated in patients with concomitant arterial hypertension to identify the state of the renal arteries.
3. Significant risk factors in these patients are ischaemic heart disease (44.1%), arterial hypertension (49%), haemostasis disorders (almost 100%).
4. The leading concomitant disease in the development of postoperative complications is ischaemic heart disease. Its share in abdominal aortic aneurysms is 40%. Postoperative cardiac complications reach 14.9%. Diagnostics of ischaemic heart disease should be based on the stage-by-stage detection of coronary lesions and its functional-compensatory abilities.
5. The main complications of the postoperative period after ABA resections are acute heart failure (14,9%), cerebral circulatory disorders (1,5%), acute renal failure (3,33%).
6. When significant coronary vascular channel lesions are detected in patients with ABA, it is fundamental to solve the issue of intervention staging. At 3-4 functional classes of circulatory insufficiency, appearance of new zones of hypo- or akinesia, decrease of ejection fraction below 40%, the first stage should be myocardial revascularisation surgery
7. In patients with combined lesions of brachiocephalic vessels in patients with ABA it is reasonable to assess the cerebral blood flow. In the presence of 70% or more stenosis of VCA, presence of embologenic plaque, bilateral haemodynamically significant stenosis it is necessary to perform carotid artery intervention as the first stage.
8. One of the most difficult problems of reconstructive operations in ABA is the contiguous lesion of renal and visceral branches of the abdominal aorta. The principle is their one-stage reconstruction. The types of reconstruction of these branches should be variable depending on the volume and extent of the pathological process.
9. Patients with aneurysmal lesion of abdominal aorta initially always have significant disorders of haemostasis system. In 30% of patients with occlusive diseases of aorta and its branches in the preoperative period the activity of thrombocytic-vascular link of hemostasis is increased, antithrombotic ability of vascular wall endothelium is decreased and blood rheological properties are disturbed. Activation of fibrinolysis was noted in patients with aneurysmal lesion of abdominal aorta.
10. During the operation for abdominal aortic aneurysmal lesion, after starting the blood flow the level of plasminogen increases additionally by 30%, which is a risk factor for haemorrhagic complications in the perioperative period. On the 1-3 day after the operation there is a significant decrease of blood anticoagulant potential - antithrombin-Sh by 25-27%, protein C by 23-25%. This period is the most dangerous in terms of thrombohemorrhagic complications development.
11. When using standard heparin during the operation there is a consumption of antithrombin-Sh by 30-45% and increase of platelet aggregation by 10%, which is a threatening condition for the occurrence of thrombosis of deep veins of the lower extremities with subsequent TELA. When using fraxiparin during reconstructive vascular surgeries the consumption of antithrombin-Sh and increase in platelet aggregation do not occur, prothrombin time, activated partial thromboplastin time, thrombin time are lengthened insignificantly that testifies to expediency of its use for prevention of thrombohemorrhagic complications.
12. Application of the diagnostic methods proposed by us to detect the main risk factors during the operation and in the nearest postoperative period, use of the algorithm of stage and volume of intervention allowed to reduce significantly the number of threatening complications, thus the lethality decreased 4 times, and the number of non-fatal complications - 4 times non-fatal complications - 1.5 times.

The objective of this study was to assess the efficacy of a complex therapeutic approach, which included retrobulbar catheterisation and magnetic stimulation of the optic nerve, in patients with ChASN of diverse aetiologies. This was achieved by analysing the clinical and functional characteristics of the eye in these patients.
The methodology employed in this study is outlined below. A total of 105 patients (155 eyes) with a diagnosis of partial optic nerve atrophy of different genesis (PAN) were included in the study. These patients received conventional treatment, treatment by the method of retrobulbar catheterisation, as well as the method of retrobulbar catheterisation combined with MS for 10 days. The dynamics of OD, visual field parameters, electrophysiological studies, ophthalmoscopy and ultrasound Dopplerography were investigated.
The results demonstrated that the combined method of treatment was more effective than the conventional method alone. The analysis of the obtained data indicates that the effectiveness of the proposed methods of treatment depends on the degree of MN destruction. Therefore, the treatment is more effective in the second degree of ChASN. However, in the group of patients treated by the combined method, the efficiency is equally high in both the second and third degrees of ChASN.
The data on the dynamics of visual acuity of patients with II stage of ChASN during treatment indicates that if in the group of patients treated by the traditional method the effect was observed in only 64.3% of cases, in the group of patients treated by the method of retrobulbar catheterisation the efficiency was observed in 89.3%.
The efficacy of the combined method of retrobulbar catheterisation in combination with MS in treating patients with ChASN was also demonstrated by the observed improvement in OZ in comparison with the control group. In this group, the effectiveness of the treatment was 90.9%.
The visual field boundaries in patients with the II degree of ChASN of the II and III main groups expanded in comparison with the control group by more than 51-60° in the periphery. The number of absolute central and paracentral scotomas decreased in comparison with the control group by 4.7 and 5 conventional units.
In the group of patients with ChASN stage III, the borders of the visual field in groups II and III, in comparison with the control group, exhibited a peripheral widening of 69° and 70°. The number of scotomas decreased by 6 and 11.6 conventional units in comparison with group I.
The ocular fundus condition under the proposed methods of treatment underwent the following changes due to the short period of observation (2-3 weeks): dilation of CAC vessels, reduction of capillary tortuosity, reduction of retinal oedema, as well as appearance of foveal and macular reflexes distinctness.
The data from ultrasound Dopplerography demonstrated a significant improvement in haemodynamic parameters in the central artery of the retina (CAC) in patients with central artery syndrome of different aetiology in the early stages following treatment. An improvement in systolic pressure indices was observed. In each case of the examined patients, an improvement in haemodynamic resistance index (Ri) towards normalisation was revealed. Consequently, there was a significant increase in diastolic pressure.
Unique Injury therapy is one of the significant territories in clinical and nursing practice that has stood out of wellbeing experts in view of the rising occurrence of constant injuries combined with their various related financial outcomes to people and governments. The target of this work was to research the adequacy and patient's Experiences of worm treatment in the treatment of wounds. A Precise survey of subjective and quantitative examination writing was received for this work. Seven electronic data sets were efficiently looked through utilizing applicable catchphrases. An aggregate of 17 articles which met the incorporation models were chosen and basically evaluated and broke down utilizing CASP apparatus. Seventeen investigations were evaluated to find out the adequacy and patient's Experiences of worm treatment. The discoveries for adequacy of Maggot treatment show that worm treatment is better in injury debridement contrasted with customary treatment. Patients treated with Maggot treatment had differed Experiences of agony, shivering sensation, loss of craving, creepy sentiments and tingling.
Purpose of the study: to evaluate the results of complex therapy including retrobulbar catheterization and magnetic stimulation of the optic nerve in patients with ChASN of different genesis by studying clinical and functional features of the eye in this case.
Methods. 105 patients (155 eyes) with the diagnosis: partial optic nerve atrophy of different genesis (PAN) received conventional treatment, treatment with the method of retrobulbar catheterization, as well as with the method of retrobulbar catheterization in combination with MS for 10 days. The dynamics of OD indicators, visual field, electrophysiological studies, ophthalmoscopy and ultrasound Dopplerography were investigated.
Results. The analysis of the obtained data indicates that the effectiveness of the proposed methods of treatment depends on the degree of MN destruction, so the treatment is more effective in the 11th degree of ChASN. However, in the group of patients treated by the combined method the efficiency is equally high both at II and III degrees of ChASN.
According to the data of visual acuity dynamics in patients with II stage of Chasnosis in the course of treatment it follows that if in the group of patients treated by the traditional method the effect was observed only in 64,3% of cases, in the group of patients treated by the method of retrobulbar catheterization the efficiency was observed in 89,3%.
The dynamics of the ocular fundus state under the proposed methods of treatment due to the short period of observation (2-3 weeks) underwent the following changes: dilation of CAC vessels, reduction of capillary tortuosity, reduction of retinal edema, as well as the appearance of foveal and macular reflexes distinctness. The data of ultrasound Dopplerography indicate a significant improvement of hemodynamic parameters in the CAC in patients with ChASN of different genesis in early terms after treatment. Improvement of systolic pressure indices was noted. In each case of the examined patients the improvement of hemodynamic resistance index Ri towards normalization was revealed. Accordingly, there was a significant increase in diastolic pressure, indicating the strengthening of elastic-elastic properties of vessels under the influence of treatment.
In our opinion, the improvement of hemodynamic parameters after the course of the proposed method of treatment is associated with an increase in the volume of the microcirculatory channel in the area of direct influence on MN by retrobulbar catheterization and MS.

Textile industry wastewater contains various pollutants that require effective treatment before discharge. Aerobic biogranules have shown promise as a sustainable and efficient solution for wastewater treatment. This study investigates the effect of a static mixer on aerobic biogranules formation for textile industry wastewater treatment. The static mixer is introduced in the wastewater treatment process to enhance mixing and promote the formation of aerobic biogranules, which are dense microbial aggregates capable of degrading organic pollutants. Laboratory-scale experiments are conducted to compare the performance of aerobic bioreactors with and without the static mixer. Parameters such as pollutant removal efficiency, biogranule characteristics, and system stability are evaluated. The results demonstrate that the use of a static mixer significantly enhances the formation of aerobic biogranules, leading to improved wastewater treatment performance. The findings of this study contribute to the understanding of the role of mixing in aerobic biogranule formation and provide insights for the optimization of textile industry wastewater treatment processes.
According to the World Health Organization, in recent years there has been an increase in the incidence of acute respiratory viral infection. In this regard, the attention of pediatricians and otolaryngologists is attracted by acute stenosing -laryngotracheitis (ASLT). According to the data of many years of research, the number of patients with ASLT ranges from 0.1 to 0.4% of all children hospitalized with a diagnosis of acute respiratory viral infection. The development of stenosing laryngotracheitis in acute respiratory viral infection (AR.VI) dramatically aggravates the condition of sick children, and sometimes the life of a child depends on its attachment to the underlying disease.
Since the first days of independence , large-scale reforms have been consistently implemented in our country in order to improve the quality of medical care for the population . Thus, effective medical care for children ensured timely detection, early diagnosis and treatment of patients with ASLT, which made it possible to reduce the duration of their treatment in the hospital by 3-4 days.
Despite numerous scientific studies devoted to the study of the patterns of the infectious process in stenosing laryngotracheitis, the role of dysbiocenosis of the mucous membranes of the upper respiratory tract, the process of endogenous intoxication (El), which develops as a result of illness in children and its relationship with the course of the disease, as well as the state of the system of local and general immunity dictate the need to improve the methods of their correction in the light of modern requirements. At the same time, the causes of recurrence of acute stenosing laryngotracheitis have not been fully determined; an important task is to develop prognostic criteria for assessing the outcomes of OSLT.
Given the dissertation research to a certain extent serves to solve the problems provided for in the resolutions of the President of the Republic of Uzbekistan No. PP-2133 dated February 19, 2014 “On the State Program" The Year of a Healthy Child ’’and No. PP-2221 dated August 1, 2014 “On the State Program for Further Strengthening reproductive health of the population, protection of the health of mothers, children and adolescents in Uzbekistan for the period 2014-2018”, as well as in other legal documents adopted in this area.
Scientific research aimed at improving the methods of complex diagnostics, treatment and prevention of stenosing laryngotracheitis in children was carried out in many leading medical centers, such as the Schneider Children's Medical Center (Israel), Giessen University Hospital (Germany), St. Mary's Children's Clinic (Germany), Center of Innovative Medicine Interbalkan (Greece), Generale Clinic (Switzerland), Royal Clinic (Great Britain), Queens Medical Center (Great Britain), IDIBAPS Clinic (Spain), St. Luke's Hospital (Japan), Federal Scientific and Clinical Center of Otorhinolaryngology FMBA of Russia (Russia) , as well as the Tashkent Pediatric Medical Institute and the Republican Specialized Scientific and Practical Medical Center for Pediatrics (Uzbekistan).
As a result of the studies, criteria for assessing the risk of occurrence and recurrent course of OSLT were developed, the mechanisms that determine the sensitivity of the respiratory tract were identified (Freiburg Clinic, Germany); established endocrine dysfunction in children with primary and recurrent acute stenosing laryngotracheitis (Children's Hospital, Ireland); the influence of the composition of the microflora of the main loci of the body, connective tissue dysplasia, regulatory systems on the function of external respiration, the formation of threshold sensitivity and reactivity of the respiratory tract in children with recurrent stenosing laryngotracheitis (RSLT) was proved (Melbourne University, Australia).
At present, the goal of many studies in the world is to further determine at the immunomolecular level the role of specific and non-specific factors of immune protection in the pathogenesis of acute stenosing laryngotracheitis; assessment of the state of non-specific protection during OSLT; study of significant changes in the cellular link of immunity, changes in T-suppressors and partially B-lymphocytes; as well as the prevention of relapses and the improvement of methods for diagnosing and treating the disease.
As the analysis of special literature showed, a number of researchers studied the role of the allergic component and the autonomic nervous system in the pathogenesis of the development of primary and recurrent OSLT. According to the results obtained, more than 90% of sick children in the pathogenesis of primary and recurrent acute stenosing laryngotracheitis is dominated by allergic component with the identification of common and allergen-specific IgE . In addition, it has been proven that the development of OSLT in parainfluenza infection is associated with a significant increase in IgE titer and specific IgA in nasopharyngeal secretions in children with ARVI. The mechanisms of OSLT recurrence based on a significant change in the immunological reactivity of the body, which are associated with its allergization by both infectious and non-infectious agents, including adverse environmental, seasonal, meteorological and even social conditions, have been studied. It has been proven that OSLT proceeds with vegetative disorders, which, in turn, have a significant impact on the course and outcome of the underlying disease. An improved treatment of OSLT at the height of the disease is proposed, based on the use of drags, taking into account the type of initial vegetative tone of the body.
Despite numerous works devoted to the study of acute stenosing laryngotracheitis, its diagnosis and methods of treatment, the trend towards an increase in the recurrence of the disease persists, which dictates the need to study the general patterns of the infectious process in stenosing laryngotracheitis, assess the significance of the microbiocenosis of the mucous membranes of the upper respiratory tract, disorders of the immune and interferon statuses and development of ways to correct them, predict the disease on the basis of a prognostic map, as well as improve the effectiveness of treatment and preventive measures.
