Документ Morphometric features of the structural components of the hemomicrocirculatory bed in the perivulnar region of the caecum in wound defect sutured with polyfilament suture material(Aluna Publishing, 2021-06) Pronina, O. M.; Bilash, S. M.; Kobeniak, M. M.; Koptev, M. M.; Pirog-Zakaznikova, A. V.; Onipko, V. V.; Ischenko, V. I.; Проніна, Олена Миколаївна; Білаш, Сергій Михайлович; Кобеняк, Микола Миколайович; Коптев, Михайло Миколайович; Пирог-Заказникова, Ангеліна Валеріївна; Оніпко, Валентина Володимирівна; Іщенко, Володимир ІвановичThe aim: The study focuses on the morphometric features specification concerning the structural components of the hemomicrocirculatory bed of the perivulnar region of the cecum in rabbits when suturing a wound defect with synthetic polyfilament surgical suture Vicryl. Materials andmethods:The research was carried out on rabbits (n = 30: 5 animals made up the control group and 25 animals made up the experimental group) and included surgery based on the method of surgical intervention on the large intestine patented by the authors, which was performed in the conditions of the operating room at the Department of Clinical Anatomy and Operative Surgery. When determining the main morphometric parameters, we took biopsy specimens of the cecum and used paraffin and epoxy resin embedding considering the generally accepted methods. Results: The study determined that the implantation of Vicryl surgical suture material in the tissues of the cecum became a trigger for the formation of active inflammatory focus and occurrence of leukocyte infiltrate in the perivulnar region. Conclusions: Arterioles, as a resistive link, capillaries, as an exchange link and venules, as a capacitive link in the hemomicrocirculatory bed, actively participate in response to the inflammatory process and formation of a connective tissue scar. The process of structural organization of microvessels begins in the formed granulation tissue in the perivulnar region of the cecum starting from the 14th day of the experimentДокумент The impact of food additives complex on the structural organization of pulmonary diffuse lymphoid tissue shown in the experiment(Полтавський державний медичний університет, 2023) Yeroshenko, G. A.; Donets, I. M.; Shevchenko, K. V.; Riabushko, O. B.; Zviaholska, I. M.; Onipko, V. V.; Peredera, R. V.; Єрошенко, Галина Анатоліївна; Донець, Ілона Миколаївна; Шевченко, Костянтин Васильович; Рябушко, Олена Борисівна; Звягольська, Ірина Миколаївна; Оніпко, Валентина Володимирівна; Передера, Р. В.The paper presents the findings of morphometric and morphological studies of the diffuse lymphoid tissue of rat lungs under the combined effect of the food additives. It has been found that the condition of the diffuse lymphoid tissue of rat lungs, under the impact of the complex of food additives comprise of monosodium glutamate, sodium nitrite and Ponceau 4R, reflects the reaction of elements of the local defense barrier to the action of the components of the food additives’ complex, primarily functioning as antigens. This is manifested by the activation of processes of antigen-dependent differentiation of cells of the lymphoid lineage, undulating changes in the morphometric parameters and the degree of vascularization of the diffuse lung tissue.
