Item Evaluation of methotrexate toxicity(Izdatel'stvo Elm, 2023) Рябенко, Тетяна Василівна; Riabenko, Tetiana Vasylivna; Гула, Вікторія Іванівна; Hula, Viktoriia Ivanivna; Кореньков, Олексій Володимирович; Korenkov, Oleksii Volodymyrovych; Понирко, Аліна Олексіївна; Ponyrko, Alina Oleksiivna; Теслик, Тетяна Петрівна; Teslyk, Tetiana Petrivna; Дмитрук, Сергій Миколайович; Dmytruk, Serhii Mykolaiovych; Ілляшенко, Вячеслав Юрійович; Illiashenko, Viacheslav Yu.; Дудченко, Євгеній Сергійович; Dudchenko, Yevhenii SerhiiovychThe article analyzes literary sources on the study of the toxic effects of methotrexate in the treatment of various diseases and examines scientific data on methods of preventing their development. According to the literary information, the main toxic effects of methotrexate manifest as damage to the liver, kidneys, bone marrow, lungs, digestive system, and skin. Methotrexate exhibits pronounced embryotoxic and teratogenic effects. Monitoring of blood test parameters and selection of an optimal dose will minimize methotrexate toxic effects and help in achieving success in the treatment.Item Evaluatıon of methotrexate toxıcıty(Izdatel'stvo Elm, 2023) Рябенко, Тетяна Василівна; Riabenko, Tetiana Vasylivna; Гула, Вікторія Іванівна; Hula, Viktoriia Ivanivna; Кореньков, Олексій Володимирович; Korenkov, Oleksii Volodymyrovych; Понирко, Аліна Олексіївна; Ponyrko, Alina Oleksiivna; Теслик, Тетяна Петрівна; Teslyk, Tetiana Petrivna; Дмитрук, Сергій Миколайович; Dmytruk, Serhii Mykolaiovych; Ілляшенко, Вячеслав Юрійович; Illiashenko, Viacheslav Yuriiovych; Дудченко, Євгеній Сергійович; Dudchenko, Yevhenii SerhiiovychУ статті проаналізовано літературні джерела щодо вивчення токсичної дії метотрексату при лікуванні різних захворювань та досліджено наукові дані щодо методів профілактики їх розвитку. Згідно з літературними даними, основна токсична дія метотрексату проявляється в ураженні печінки, нирок, кісткового мозку, легень, травної системи, шкіри. Метотрексат має виражену ембріотоксичну та тератогенну дію. Моніторинг показників аналізу крові та підбір оптимальної дози дозволить мінімізувати токсичні ефекти метотрексату та допоможе досягти успіху в лікуванні.Item Features of morphological rearrangements of structural components in the rat pineal gland under the impact of heavy metal salts(State Institution “V. Danilevsky Institute for Endocrine Pathology Problems of the NAMS of Ukraine", 2021) Гринцова, Наталія Борисівна; Гринцова, Наталия Борисовна; Hryntsova, Nataliia Borysivna; Романюк, Анатолій Миколайович; Романюк, Анатолий Николаевич; Romaniuk, Anatolii Mykolaiovych; Hodorova, I.; Карпенко, Людмила Іванівна; Карпенко, Людмила Ивановна; Karpenko, Liudmyla Ivanivna; Бумейстер, Валентина Іванівна; Бумейстер, Валентина Ивановна; Bumeister, Valentyna Ivanivna; Дмитрук, Сергій Миколайович; Дмитрук, Сергей Николаевич; Dmytruk, Serhii Mykolaiovych; Зайцева, Станіслава Станіславівна; Зайцева, Станислава Станиславовна; Zaitseva, Stanislava StanislavivnaThe development of the pathology of individual organs and systems undoubtedly depends on adverse envi-ronmental factors. Particular attention of researchers attracts heavy metal salts. Epiphyseal hormones play a key role in regulating and maintaining basic body functions. The study was to elucidate the morphological and morphometric rearrangements the structural components changes in the pineal gland of mature rats under the influence of heavy metal salts. Materials and methods. The experiment was performed on 12 white mature male rats weighing 200–250 g at the age of 7–8 months, which were divided into 2 groups (group 1 control and group 1 experi-mental). Animals of the experimental group were simulated microelementosis by adding to drinking water a mixture of heavy metal salts for 30 days: zinc (ZnSO4 7H2O) — 5 mg/L, copper (CuSO4 5H2O) — 1 mg/L, iron (FeSO4) — 10 mg/L, manganese (MnSO4 5H2O) — 0.1 mg/L, lead (Pb(NO3)2) — 0.1 mg/L, and chromium (K2Cr2O7) — 0.1 mg/L. General morphological and statistical research methods were used (histological, morpho-metric and variational statistics methods). Results. The 30-days impact of the heavy metal salts combination on the rat body caused in the pineal gland morphological changes of nonspecific polymorphic nature, which were expressed in the increased vascular area, active glial response, hypertrophy of pinealocyte nuclei and increase of their optical density. Cytological signs in most pinealocytes indicated the predominance of indolamine synthesis over polypeptides. The main pathogenetic mechanisms of the influence of heavy metal salts on the organ have been established: change in the vascular lumen area, blood rheological properties impairment, tissue hypoxia, nucleus hypertrophy and change in their optical density. Conclusions.Morphological changes in the gland comply with the stress phase of the general adaptation syndrome. The above morphological changes negatively affected the processes of hormones evacuation into the blood, the course of the general adaptation syndrome and the homeostasis restoration in the organ.Item Biomechanical properties and macroelement element composition of long tubular bone of rats under experimental hyperglycaemia(Poltava State Medical university and Ukrainian public organization Scientific Society of Anatomists, Histologists, Embryologists and Topographoanatomists of Ukraine, 2021) Понирко, Аліна Олексіївна; Понырко, Алина Алексеевна; Ponyrko, Alina Oleksiivna; Дмитрук, Сергій Миколайович; Дмитрук, Сергей Николаевич; Dmytruk, Serhii Mykolaiovych; Бумейстер, Валентина Іванівна; Бумейстер, Валентина Ивановна; Bumeister, Valentyna IvanivnaThe pathomorphological basis for the development of diabetic disorders in various bones is a relevant subject of modern experimental research on the modeling of diabetes–associated destructive processes in the skeletal system. They are characterized by reduced bone density, which leads to an increased risk of fractures. Bone strength mainly depends on the interaction and concentration of chemical elements such as Ca, P, Mg, and K. Therefore, the purpose of our study was to determine the interdependence of changes in biomechanical parameters depending on the concentration of chemical elements in long tubular bones of rats under chronic hyperglycemia. The study was performed on 72 adult white laboratory rats lasting 180 days. It was found that starting from 30 days of uncontrolled chronic hyperglycemia, the bone mineral density in rats of the experimental group gradually decreased in comparison with the dynamics of the corresponding indexs in animals of the control group. These changes were accompanied by pronounced demineralization of both bones, as evidenced by significant losses of macronutrients (Ca, P, Mg and K). As a result, in chronic hyperglycemia gradually formed a complex violation of the structure and biomechanical properties of long tubular bones, which is a pathomorphological basis in the corresponding loci of the skeletal system.
