Introduction and Aim: The bone marrow is responsible for the supply of oxygen and restores the cells that form the blood of a tissue. The objective is to study the cadaveric bone marrow cells from dead children of different regions of Kyrgyzstan. Materials and Methods: Bone marrow examination was performed on 38 cadavers (Bishkek–11, Kara-Balta–9, Cholpon-Ata–10, and Naryn–8) of children dead due to causes unrelated to immunodeficiency. The cadaveric bone marrow cells from dead children were collected within a day after death. Results: Studies of cadaveric bone marrow cells from dead children in Kara-Balta showed an increase in basophils, eosinophils, lymphocytes, leukoerythroblastosis, and a decrease in myelocytes. Erythroid growth according to the normoblast hematopoiesis was slightly decreased. Megakaryocytes were single or absent (no function) and contained small number of platelets. Conclusion: Cadaveric bone marrow cells taken from dead children who lived near the uranium tailings dump of Kara-Balta, demonstrated an anomaly with the hematopoietic function of the bone marrow, the state of the stroma, the ratio of hematopoietic and adipose tissue, cellular composition, different pathological processes as indicated by myelocytes in comparison to dead children from other regions (Bishkek, Cholpon-Ata, and Naryn).
This paper is describing a detailed study of morphological structures and characteristics newborns thymus in different climatic and geographical conditions of Kara-Balta, Cholpon-Ata, and Bishkek in Kyrgyzstan. Anatomical structure research done on 26 thymuses of newborn corpses. Research results showed that a significant amount of thymuses consisted of lobes with very thin connective tissues between them. It is observed that the Hassall cells were usually located in the medulla part of the thymus after using the coloring by Van-Gieson's stain visible clear elastic and collagen fibers. In addition, cell population dynamics in a unit of conditional area of cortical substance thymus lobes in newborns determined.
The structure of intraorgan system of the lymphatic collectors of the heart, their size, structure and distribution in different parts of the wall of lymphangions are described. Generation and interposition of muscle fibers in the structure of the common vessel are shown. Visual description of the interaction of different structures of the lymphatic system for lymph passage, from subendocardial lymph capillaries to the main outflow vessels is described.
Introduction and Aim: Thymus atrophy occurs in response to the stress of any etiology such as cold, burn, infection, trauma, pain, and psychogenic stress. The objective of the study is to evaluate the thymus gland in children aged 7–12 years from Kyrgyzstan. Materials and Methods: The present study assessed the anatomy of the thymus gland on 35 cadavers of children aged 7–12 years from 2015 to 2020. Anatomical methods including preparation, weighing, and measurement, and histological methods including hematoxylin-eosin staining were performed. Results: In children aged 7–12 years, it was found that in the thickness of the cerebral layer, there is the growth of thymic corpuscles, blood capillaries, and lymphatic slits. The level of cells in the cerebral layer is diverse, there are lymphocytes in large numbers, larger light epithelial and reticular cells, as well as macrophages. In the cortical zone, the cellular composition is mainly lymphoid cells, and mitosis was found in some of them. Conclusion: In this study, comparatively, the cortical zone prevails over the cerebral one. At this age, the thymus begins to atrophy, as well as the growth of adipose tissue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
