Material and methods. The study was performed on 34 male Wistar rats, which were divided into 4 groups: 1 – intact, 2 – rats, which received selenium only for 1 month, 3 – animals, which were injected once intraperitoneal urethane, 4 – rats with combined selenium and urethane action. Histological preparations of the thymus were prepared according to generally accepted methods and further evaluated by the method of review microscopy, morphometry, immunohistochemical reactions, electron microscopy, statistical processing of data. Results. Ninety days after selenium, the rat thymus structure is slightly different from intact animals. The introduction of urethane leads to the development of excitation involution of the thymus, which is characterized by morphological changes, and manifests itself in a change in the shape of the organ lobes, in the expansion of the intercole gaps and in the fat tissue thereof, hyperplasia of the cortical substance of the thymus by increasing the number of mature lymphocytes, epithelial cells positive to pancytokeratin. At the ultramicroscopic level, the thymus lymphocyte decreases its nuclear-cytoplasmic index, and increases the number of mitochondria that have a light matrix with a small amount of crystal. Apoptotic bodies and a large number of electron-transparent vacuoles are visualized. When combined, the thymus structure differs from the intact group by an enlarged brain substance, but the number of epithelial cells that are positive to pancytokeratin and Ki67+-cells, as well as cells that express apoptosisregulating protein, decreases. Electron microscopy also indicates a large amount of mitochondria, but with welldefined crystals, when combined with selenium and urethane. There are a small number of electron-transparent vacuoles. Conclusion. The obtained data make it possible to draw a conclusion about the positive influence of the exchange rate of selenium on the T-cell link of immunity, at least for this period of study. In the course of the experiment, it was found that, against the background of the development of the adenoma of the lung caused by the introduction of urethane, at the stage of alveolar epithelium dysplasia signs of excitant thymus involution were detected. When selenium and urethane are combined, less pronounced changes are observed in the examined organ than in the isolated administration of urethane.","PeriodicalId":15028,"journal":{"name":"Journal of Anatomy and Histopathology","volume":"26 114","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140734782","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}

Morphometric analysis and statistical processing of the actual material were carried out. Results. It was shown that the organotypic differentiation of the intermediate mesenchyme and the formation of nephrons of the provisional and definitive urinary organs control the state of the mesonephric duct and metanephritic diverticulum. The mesonephric duct initiates the organotypic antibiotic of the perifocal intermediate mesonephric mesenchyme and detects the proximodistal vector of saltatory mesonephronogenesis. The metanephritic diverticulum and its daughter branches initiate the organotypic differentiation of the intermediate mesenchyme and control the fan mechanism of metanephronogenesis.

The absence of ventrodorsal generation of mesonephrons in humans is associated with a significant vital cycle of a normal kidney, atrophy of the mesonephric duct, and a decrease in the activity of immunocompetent cells. An increase in the expression of CD31, CD34, Bcl-2, Ki-67 positive cells is realized in combination with the formation of nephron rudiments as the promoter organs move in the developing organ of urinary formation. Conclusion. Prenatal organogenesis monitors and constantly monitors the formation of promoter organs of morphogenesis - the mesonephric duct and the metanephric disserticulum. Organotypic infection of the intermediate mesenchyme during the development of fish, birds and humans correlates with the chronovector of the convergence of immunocompetent cells.","PeriodicalId":15028,"journal":{"name":"Journal of Anatomy and Histopathology","volume":"32 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140735563","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 purpose of the study is to evaluate the dynamics of indicators of the component composition of the body of military university cadets during the training period from 1st to 6th year. Material and methods. 387 male cadets (the same persons) were examined during the period of their studies in 1-6 courses. The component composition of the body was studied using bioimpedance measurements. Results. It has been shown that during the first two courses of study (persons 17-18 years old) there is an increase in muscle mass of the trunk by 13.8%, muscle mass of the upper extremities - by 11.4% and lower extremities - by 6.1%, which is explained by the presence intense physical activity. Moreover, during the first year of study, a slight increase in the fat component of the body is determined (5.4%). In the third and fourth years of study, there is a stabilization and slowdown in the growth of the formed muscle and fat masses of the trunk and limbs, characteristic of the transition period from adolescence to adulthood. These trends continued to increase throughout the 5th year of study, but the level of basal metabolism did not change significantly throughout the study. In the 6th year, in relation to the time of admission to university, a general increase in the muscle component of the torso was established by 17.2%, muscle mass of the upper extremities - by 15.8%, and lower extremities - by 9.6%. Over 6 years of study, the fat content in the torso increased by 8.2%, the fat mass of the upper and lower extremities - by 7.5% and 8.0%, respectively, and the level of visceral fat increased by 9.3%. The vital volume of the lungs increased by 12.2% compared to the beginning of the 1st course. Conclusion. The above transformations are obviously due to the continued growth of a healthy organism. Reduced adaptive changes during the training period can be corrected by increasing physical activity, diet and caloric intake.","PeriodicalId":15028,"journal":{"name":"Journal of Anatomy and Histopathology","volume":"27 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140734315","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}

Since diagnosis of thyroid pathology is associated with ultrasound examination, advanced information about the regional features of the anatomical standad parameters of the thyroid gland remains an acute research and practical issue. The aim of the study was to identify the morphometric parameter features of the thyroid gland during ultrasound scanning and the nature of their relationship with the somatotype in young men living in the Republic of Sakha (Yakutia), indigenous and non-indigenous ethnic groups. Material and methods. The study involved total 195 males, aged 17-21, who were divided into groups depending on indigenous and non-indigenous ethnicity. All subjects underwent anthropometric measurements of 10 parameters, followed by determination of the somatotype according to Heath-Carter. To determine the linear dimensions and volume of the thyroid gland, the ultrasound diagnostic option was used. Results. As stated, representatives of the mesomorphic somatotype predominate among young men of the indigenous ethnic group; representatives of the ectomorphic somatotype predominate among young men of the non-indigenous ethnic group. A comparative analysis of ultrasound morphometry revealed significantly larger values of the total volume of the thyroid gland, due to an increased thickness and volume of the right lobe, as well as the thickness, width and volume of the left lobe in young men of the non-indigenous ethnic group, compared with young men of the indigenous ethnic group. When comparing the thyroid volume with the identified distribution of somatotypes according to Heath-Carter, statistically significant differences were registered in representatives of the mesomorphic somatotype: in young men of the non-indigenous ethnic group, the volume was 2.1 cm3 greater than in young men of the indigenous ethnic group. Conclusion. Thus, the obtained findings related to linear parameters and thyroid volume evidence their relationship with ethnicity and somatotype.","PeriodicalId":15028,"journal":{"name":"Journal of Anatomy and Histopathology","volume":"5 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140735537","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}

Conclusion. Anthropometric indicators of girls and boys living in the Moscow region have a number of features. Persons with a mesomorphic somatotype predominate, which indicates the harmonious physical development of boys and girls. Most girls have a transversely narrowed shape of the pelvis, which indicates a possible risk of obstetric complications in the event of pregnancy and childbirth. Otherwise, both boys and girls develop proportionally in accordance with the parameters of the biological and physiological norm.","PeriodicalId":15028,"journal":{"name":"Journal of Anatomy and Histopathology","volume":"2 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139525648","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. Using light and electron microscopy, immunohistochemistry and morphometry, the testes of representatives of various classes of vertebrates (amphibians, reptiles, birds and mammals) were studied. The collection of material was carried out in environmentally safe ecosystems and in ecosystems with high anthropogenic load in the Orenburg region of Russia and in the Aktobe region of the Republic of Kazakhstan. Results. Based on the material of our own studies of the gonads, as well as on the basis of information from modern domestic and foreign literature, the patterns of relationships between germ cells and somatic cells of their microenvironment in the testes of vertebrates are shown. The features of the structural organization of the germinal and endocrine components of the male gonads are considered. The features of the structural organization of intertitial endocrinocytes (Leydig cells) are shown, and their high resistance to the action of various destabilizing factors compared to spermatogenic epithelium is established. Pubertal generation of endocrinocytes in vertebrate testes during reproductive age is characterized by stability in cell numbers and belongs to cell populations of a stable type. The role and significance of the structures of the blood-testis barrier are shown and the morphological equivalents of changes in the permeability of this barrier are established; it is revealed that in the studied animals, under the influence of negative anthropogenic factors, the integrity of the blood-testis barrier in the testes is violated. The action of destabilizing factors leads to a decrease in the number of developing germ cells in the lumen of the epididymal tubules (up to their complete disappearance in individual individuals), which is probably due to the deterioration of the trophic influences on them from the structures of the epididymis. Conclusion. The principle of organization of the main compartments of the testes, the convoluted seminiferous tubules and the interstitium of the organ, formed during evolution, probably turned out to be evolutionarily advantageous, since it is represented in the testes of all amniotes - reptiles, birds and mammals. In the process of evolutionary development, several types of structural organization of convoluted seminiferous tubules and interstitium were formed in the testes of vertebrates.
