Material and methods. The material for the study was the thymus of stillborn children (n=16) aged 35-40 weeks who died as a result of asphyxia, the cause of which was not established. All sectional material was carefully selected according to the anamnesis in order to exclude causes that could affect the structure of the thymus The study was carried out using standard methods of light microscopy, histology and immunohistochemistry. The following characteristics of the thymus were studied: corticomedullary and mitotic indices, the numerical density of thymocytes in the cortex and medulla, the relative area occupied by the blood-stream, fibrous connective, adipose, and lymphoid tissues on a section of the thymus lobes. The relative number of thymic bodies, as well as the quantitative ratio of thymocytes with the immunophenotypes of cytotoxic (CD8+) and helper cells (CD4+) were identified. Results. In the thymus of human fetuses, the values of the corticomedullary and mitotic indices were 4.8±0.63 and 2.69±0.36%, respectively. Young thymic corpuscles (TT I) quantitatively predominate over mature (TT II) and aging corpuscles (TT III), 1.5 and 3 times, respectively. A histological section of the thymus did not reveal fatty degeneration; the relative amount of fibrous connective tissue was 5.22 (3.8464; 5.6330)%. The cortical-cerebral boundary had clear outlines. T lymphocytes, together with cells of the epithelial microenvironment, occupied more than 90% of the area of the histological section. In the thymus cortex, a high numerical density of thymocytes was found (679.95±46.9), among which cells expressing the CD8+ coreceptor on the surface of the membrane predominated (72.64±5.05%). In the medulla, the number of T-lymphocytes with CD4+ and CD8+ phenotypes was the same (28.81±4.37% and 26.10±5.61%, respectively), the numerical density of thymocytes was 403.61±28.9 cells. Conclusion. The state of the thymus gland in human fetuses at 35–40 weeks of the fetal period indicates a high level of its functional activity. The absence of noticeable signs of accidental involution of the thymus indicates that asphyxia, not aggravated by infectious influences, and also not accompanied by developmental anomalies, due to its transience, does not have a significant effect on the morphology of the thymus and its functions. The quantitative ratio of thymocyte subpopulations with the CD8+ and CD4+ phenotype may indicate different rates of migration of these cells to the periphery, or indicate a different nature of the interaction of developing T lymphocytes with epithelial cells carrying MHC class I and II complexes.","PeriodicalId":15028,"journal":{"name":"Journal of Anatomy and Histopathology","volume":" 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141677656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to evaluate the dynamics of changes in indicators of the component composition of the body of practically healthy female cadets aged 17–23 years during the period of study at a military university. Material and methods. The dynamics of the component composition of the body of military university applicants and female cadets during the period of their studies in 1–6 years was studied. Results. Based on the results of a comprehensive examination of the same individuals, which included an assessment of 15 indicators of body composition and 5 functional indicators, a database was formed. It has been shown that during the first two years of study, compared with the indicators of applicants, the most intense increase in muscle mass of the torso and upper extremities occurs – by 14.9% and 12.6%, respectively. An increase in fat mass in the trunk and lower extremities is observed only by the fourth year and amounts to 11.2% and 12.8%, respectively. Sexual characteristics of changes in the component composition of the body of girls are characterized by a more intense growth of the fat component, which corresponds to the physiological changes in the woman’s body during the transition to the first mature period of development. Conclusion. In senior years of study, there is a stabilization of the dynamics of muscle mass development, physical development rating, level of basal metabolism and functional indicators. The identified changes in the component composition of the body during the training period of female cadets are due to the peculiarities of the intensity and nature of physical activity, the work and rest regime and the nutrient composition of the daily diet, as well as endocrine status.","PeriodicalId":15028,"journal":{"name":"Journal of Anatomy and Histopathology","volume":"159 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141681914","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and methods. Four experimental groups of animals were formed, consisting of white male rats representing different stages of liver recovery (no recovery, 4, 8, and 12 weeks of recovery) after chemically induced liver fibrosis, and a control group of intact animals, with 8 animals in each group. The dynamics of the distribution of intermediate filaments of mesenchymal cells were analyzed on preparations stained by immunohistochemical method using antibodies to vimentin and α-SMA. Results. After chemically induced liver fibrosis, a significant increase in the specific area of vimentin and α-SMA was observed, suggesting an important role of mesenchymal cells in the remodeling of the liver parenchyma. At the 4th week, the increased number of vimentin- and α-SMA-positive cells persisted, with these cells localized along fibrous septa and around blood vessels. At this stage, regenerative rosette-like structures consisting of vimentin- and α-SMA-positive mesenchymal cells surrounded by young regenerating hepatocytes were formed. By the 8th–12th weeks of regeneration, a decrease in the specific area of these markers was noted; however, vimentin- and α-SMA-positive cells were still present near portal triads and blood vessels, indicating ongoing regeneration processes. Conclusion. Vimentin and α-SMA play a key role in the formation of the fibrous matrix and the activation of perisinusoidal cells and myofibroblasts. The observed correlation between changes in vimentin and α-SMA indicates their coordinated involvement in the processes of fibrosis and regeneration.  ","PeriodicalId":15028,"journal":{"name":"Journal of Anatomy and Histopathology","volume":"48 s235","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141683163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pelvic floor muscles perform an important function throughout a woman’s life. They provide fixation and maintenance of the pelvic organs, stretches during childbirth, ensuring the formation of the birth canal, and are a potential site for the formation of a hernia in the female body. Impaired function of this muscle group can lead to either excessive muscle contraction (chronic pelvic pain syndrome) or excessive stretching (pelvic organ prolapse). The purpose of the study is to assess the morphometric properties of the pelvic floor muscles in nulliparous women using 3D ultrasound scanning (sonography). Material and methods. The observation group consisted of 60 women of middle reproductive age who applied for an appointment with an obstetriciangynecologist with complaints of pain of various types localized in the perineum and pelvis, decreased desire and quality of sexual life, clinically confirmed by a diagnosis of incompetence of the pelvic floor muscles. The control group consisted of 30 women without dysfunction of the pelvic floor muscles according to clinical examination. The main criterion for inclusion of patients in the study was reproductive age - 18–45 years and natural childbirth in obstetric and gynecological history. Results. We found that the absence of visible sonographic markers of changes in the myofascial structures of the pelvis is not a prognostically significant criterion for muscle dysfunction, since predominantly changes in morphometric parameters are a reliable sign of the formation of pelvic floor muscle failure. Conclusion. The ultrasound morphometry method, which allows one to assess dynamic changes in the size of muscle and fascial structures, can be used in the clinical practice of an obstetrician-gynecologist. Early diagnosis of a violation of the structure of pelvis myofascial complex will allow early implementation of measures aimed at prevention and timely treatment.","PeriodicalId":15028,"journal":{"name":"Journal of Anatomy and Histopathology","volume":"58 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140733479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and methods. The study was performed on tomograms of the chest of 191 men aged from 20 to 70 years. Measurements on tomograms were carried out in the axial plane using the RadiAnt program. The scans measured the optical density of the first rib tubercle, the distal bony part of the first rib, and the base of scapula coracoid process. All measurements were taken in men randomized by age and chest shape. The results of osteometry were processed by statistical methods. Results. The chest shape determines age-related changes in the optical density of bone tissue. In individuals with intermediate and transverse chest shapes, a decrease in the optical density of bone tissue at the base of scapula coracoid process begins to appear at the age of 30–50 years. These changes are most pronounced for the base of coracoid process, regardless of the chest shape, at the age of over 50 years. A decrease in the optical density of the first rib tubercle manifests over the age of 50 years in individuals with intermediate and transverse chest shape. In individuals with a gracile chest shape, the optical density of the bone structure is more stable. The tubercle of the first rib, along with the base of coracoid process, can serve as a prognostic area in the diagnosis of systemic osteoporosis in individuals with transverse and intermediate chest shape. Conclusion. A deterministic approach to the described indicators of changes in the optical density of bone tissue of the first rib and scapula in individuals with different chest shapes, according to SCT tomograms, objectively helps to predict and subsequently verify the manifestations of osteoporosis. The dependences we have identified on changes in bone tissue density and in the structure of correlations between the studied parameters of the first rib and the coracoid process indicate pronounced somatotypic variability, which must be taken into account when developing restorative treatment and predicting the course of orthopedic diseases in people of different age.","PeriodicalId":15028,"journal":{"name":"Journal of Anatomy and Histopathology","volume":"16 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140732841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Material and methods. The density of neurons and glial cells, the cross-sectional area of nuclei, nucleoli and perikarya of LTN neurons were determined in patients with VD (n=10) and in the control group of individuals (n=10) who did not have any neurological or cognitive dysfunction. Comparison of indicators between groups was carried out using ANOVA and Student's t-test. Results. In VD cases all of the studied morphometric parameters of neurons and their density were decreased by within 20% (p<0.02). An increase in the neuroglial index by an average of 27% (p=0.04) was also noted. Сhanges in the size of neurons and nucleoli were observed regardless of the gender of patients. However, a decrease in the neuronal density (p = 0,008) and an increase in the neuroglial index (p=0,03) were noted only in the group of female patients. Conclusion. VD leads to a decrease in the metabolic activity of neurons of the hypothalamus and of the lateral tuberal nucleus, in particular. Moreover, a part of LTN neurons dies inducing a compensatory and adaptive increase in the population of glial cells. Thus, some late manifestations of VD, such as asthenia and increased exhaustion, may be caused, at least in part by a decrease in the neuronal activity and reorganization of intercellular interactions in the LTN.","PeriodicalId":15028,"journal":{"name":"Journal of Anatomy and Histopathology","volume":"11 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140735916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
