Документ Microscopic structure and the process of formation of milky spots of the greater omentum of white rats(Полтавський державний медичний університет, 2023) Hryn, V. H.; Kostylenko, Yu. P.; Maksymenko, O. S.; Tykhonova, O. O.; Tarasenko, Ya. A.; Korchan, N. O.; Гринь, Володимир Григорович; Костиленко, Юрій Петрович; Максименко, Олександр Сергійович; Тихонова, Олеся Олександрівна; Тарасенко, Яна Альбертівна; Корчан, Наталія ОлександрівнаTo study the microscopic structure and the process of forming milky spots of the greater omentum of white rats, an experimental study was carried out on 15 male white rats of reproductive age, weighing 278.08 to 346.47 grams. The materials were preparations of the greater omentum, fixed in a 10 % neutral formalin solution, as well as total preparations stained with a hematoxylin-eosin solution. Milky spots of the greater omentum of white rats are presented as small lymphoid nodules of various shapes and sizes, which are orderly dispersed within the vascular-fatty arcades on the sides of the axial blood vessels. The smallest were located in the depth of the adipose tissue, adjacent to the axial vessels, and the largest were outside it. Along with them, there were also forms that occupy an intermediate position. All the main types of immunocompetent cells were concentrated in a certain order in the milky spots of the greater omentum.Документ Morphofunctional and clinical significance of APUD cells visualized in some tissues of human organs(2023) Sherstyuk, О. O.; Ustenko, R. L.; Tykhonova, O. O.; Tarasenko, J. A.; Katsenko, A. L.; Lytovka, V. V.; Korchan, N. O.; Шерстюк, Олег Олексійович; Устенко, Роман Леонідович; Тихонова, Олеся Олександрівна; Тарасенко, Яна Альбертівна; Литовка, Володимир Вікторович; Корчан, Наталія Олександрівна; Каценко, Андрій ЛюбославовичDifferent organs and systems of the human body contain diffusely located and so-called APUD cells. There are about 40 of their varieties for today. The article provides modern information about the localization, structural features and role of this group of cells, as well as their clinical significance. Archival data of biopsies of palatine, labial, lacrimal glands, stomach, gums, and prostate gland of a person in the condition of their normal intravital functioning were studied. Some morphological and functional characteristics of APUD cells from the palatal salivary gland, interdental gingival papilla, gastric pyloric gland, and human prostate gland have been reported. The study of APUD cells retains important clinical significance because it is the basis for the treatment of apudomas.
