Background. In Ukraine, there has recently been an increase in the number of limb bone fractures among the population, in particular, due to increase in the number of elderly people, which is associated with the development of age-related osteoporosis and fragility of bones. Therefore, the use of artificial implants in traumatology is becoming increasingly important. The search for new bioinert and biodegradable materials, that are capable of providing rapid fracture consolidation and do not require repeated surgical intervention, continues. Objective. To elaborate a model for the research of using carbon-carbon composite nail for intramedullary osteosynthesis in laboratory rats with fractures of femur and tibia in norm and with experimental osteoporosis. Methods. The work investigated the lower limbs of 6 groups of Wistar rats. The first part of the study involved 4 groups of rats with modeled tibial fracture with subsequent osteosynthesis in norm and with experimental osteoporosis. The second part of the research included two groups of laboratory rats with modeled femur fracture. In both parts we used metal injection needle, as well as carbon-carbon composite nail for osteosynthesis. Results. All animals underwent surgery well, stepped on the injured limb. X-ray examination after the osteosynthesis demonstrated satisfactory reposition of the fragments. One month after modeled fracture in rats with experimental osteoporosis a violation of the normal consolidation of the fracture was observed, especially in the group where carbon-carbon composite nails were used for osteosynthesis. Further, until the 180th day after the surgery there were no peculiarities, function of the limbs was restored, mainly without expressed angular deformities. Conclusion. The above mentioned model was successfully elaborated for the research of using carbon-carbon composite nail for intramedullary osteosynthesis in laboratory rats with fractures of femur and tibia in norm and with experimental osteoporosis.

Background. Establishing fetal anatomical variability of intramuscular nerves and their connections plays an important role in the search for and development of new methods for the diagnostic and treatment posterior region of the leg. Objective – to find out the topographic and anatomical features of the innervation of the triceps surae in human fetuses 4-6 months. Methods. The study was performed on 46 human fetuses 81.0-230.0 mm crown-rump length (CRL) length using macromicroscopic preparation, vascular injection, and morphometry. Results. In early human fetuses, the anatomical variability of the distribution of intramuscular nerves in the thickness of the triceps surae was established, which is due to the variability of the structure and topography of the tibial nerve, structural and functional organization of triceps surae, arterial branching and interneural connections in the thickness of the heads of the gastrocnemius and soleus in fetuses of different and the same age groups, and sometimes in the same fetus. Conclusion. The main source of innervation of the triceps surae is the tibial nerve, which can be presented by a single trunk, main and additional trunks, or several independent trunks. The nerves in the thickness of the triceps are unevenly distributed. The highest concentration of muscular branches of the tibial nerve is determined in the medial head of the gastrocnemius and the medial part of the soleus. Information on fetal topography of intramuscular nerves in the thickness of the right and left triceps surae, as well as forms of their anatomical variability, both in fetuses of different and the same age and sometimes in the same fetus, due to structural-functional organization of the components of the triceps surae, the type of branching of arteries and nerves in the thickness of the heads of the gastrocnemius and soleus. Atypical variants of the topography of the tibial nerve and common fibular nerve in early fetuses, as well as interneural connections in the thickness of the components of the triceps surae, are more common on the right lower leg.

Neural crest (NC) is a population of cells, formed at the intersection between non-neural ectoderm and neural tube. Neural crest progenitors are multipotent, have capacity to extensive migration and self-renewal. They can be differentiated into various cells types from craniofacial skeletal tissues to components of peripheral nervous system. Influence of signaling molecules and transcription factors, which are expressed at the different stages regulate development of NC. The regulatory network of genes determines the processes of induction, specification, migration and differentiation of neural crest cells (NCC). The purpose of this article is to compare the characteristics of NCC, obtained from tissues of the embryo, fetus and adult; experimental strategies for obtaining NCC from embryonic stem cells, induced pluripotent stem cells, skin fibroblasts; comparison of the potential of different cell types for therapeutic use in a clinical setting. Embryonic stem NCC are differentiated to the trunk, cranial, cardiac, circumpharyngeal and vagal according to the area of their initial migration. Mature stem NCC can be obtained from the dorsal root ganglia, red bone marrow, hair follicle, skin, intestines, carotid body, heart, cornea, iris, dental pulp, hard palate and oral mucosa. Genetic mutations may lead to failure of regulation of NC development, which leads to many congenital human diseases such as cardiovascular defects, craniofacial abnormalities and intestinal aganglionosis, collectively known as neurocristopathies. The identification and isolation of multipotent stem NCC derived from adult tissues, embryonic stem cells, and induced pluripotent stem cells are promising source for regenerative medicine.

Background. Nowadays, it has been proven that along with the invasion of individual tumor cells, their group migration occurs in the invasive front of the tumor, and this is an important factor in tumor progression. Objective: to determine the features of tumor cell invasion in the invasive front (IF) of invasive ductal breast cancer (BCa) without special specific features (IC NST) and to establish associative links between them and the clinical and pathological characteristics of the disease. Methods. The study was performed on BCa samples (after hematoxylin and eosin stained) from 120 patients with invasive ductal BCa I-II stage with G2 grade of tumor differentiation that didn’t receive neoadjuvant chemotherapy. Results. Tumors were divided into 3 groups: with predominance of parenchymal component (PC), with the larger component of connective tissue, and relatively equivalent ratio of these components. Within the IF of the studied tumors of patients with ІІ stage of the tumor process, group invasion of tumor structures was mainly determined, both separately and in combination. In particular, an increase in solid structures in tumors with a predominance of the PC, and in neoplasms with expressed desmoplastic changes in connective tissue and their advantage, - alveolar, tubular, discrete. Conclusion. In tumors of patients with invasive ductal BCa in the invasive front is dominated by collective migration of tumor cells, which is the starting mechanism of tumor progression and the first step of the metastatic process. Defined associative links between the features of tumor cell invasion and the clinical and pathological characteristics of the tumor process in BCa patients can be used in predicting this form of cancer.
背景。目前已经证明，随着单个肿瘤细胞的侵袭，它们的群体迁移发生在肿瘤的侵袭前部，这是肿瘤进展的重要因素。目的:探讨无特殊特征性的浸润性导管性乳腺癌(invasive ductal breast cancer, BCa)浸润前沿(invasive front, IF)肿瘤细胞浸润的特征，并建立其与疾病临床病理特征的关联联系。方法。本研究对120例浸润性导管BCa I-II期、肿瘤分化为G2级、未接受新辅助化疗的BCa样本(苏木精和伊红染色后)进行研究。结果。将肿瘤分为以实质成分(PC)为主、结缔组织成分较多、比例相对相当3组。在肿瘤进程ІІ期患者所研究肿瘤的IF范围内，主要确定肿瘤结构的群体侵袭，有单独的，也有联合的。特别是，在以PC为主的肿瘤中，以及在结缔组织中表达结缔组织改变的肿瘤中，实体结构的增加及其优势-肺泡，管状，离散。结论。在浸润性导管BCa患者的肿瘤中，浸润前沿以肿瘤细胞的集体迁移为主，这是肿瘤进展的起始机制，也是转移过程的第一步。BCa患者肿瘤细胞侵袭特征与肿瘤过程的临床和病理特征之间明确的关联关系可用于预测这种类型的癌症。

Background. To the present day, a high rate of unsatisfactory amputation results still exists. The healing of the bone residual limb, the main support element of the residual limb, is of particular importance. Objective. To study the impact of postamputation pain syndrome on the nature of reparative processes in the bone residual limb. Methods. Three series of experiments were performed on 45 rabbits, 15 in each with mid-third thigh amputation and muscular plasty. In series 1 and 2, a perineural catheter was attached to the sciatic nerve stump during amputation, and mechanical irritation of the nerve was performed daily for 20 minutes in series 1 for 20 days. In series 2, 0.3 ml of 1% lidocaine was injected through the catheter into the circumference of the nerve twice daily for 20 days. Animals of series 3 served as a control. The follow-up periods were 1, 3, 6 months. The study method was histological with infusion of the vessels with ink-gelatin mixture. Results. In series 1, there was a sharp disturbance of the reparative process, which consisted in shape changes, resorption of the cortical diaphyseal plate, stump deformity, absence of bone closure plate formation, and microcirculatory disturbances. In most experiments of the 2nd series, organotypic stumps were formed with normalized microcirculation. In series 3, the results of the residual limb formation were better than in series 1, but worse than in series 2. Conclusion. In the absence of pain syndrome, the bone stump after amputation at the diaphysis level over a period of 1, 3, 6 months retains its cylindrical shape, the structure of the cortical diaphyseal plate, the content of the medullary canal with normal microcirculation, the formation of the bone closure plate, and the completion of the reparative process. The presence of postamputation pain syndrome in the stump distorts the course of the reparative process with the development of pathological remodeling of bone tissue.
背景。到目前为止，截肢效果不理想的比例仍然很高。残肢骨作为残肢的主要支撑元素，其愈合尤为重要。目标。目的研究截肢后疼痛综合征对骨残肢修复过程性质的影响。方法。采用三组实验，45只家兔，每组15只，分别进行大腿中段截肢和肌肉成形术。在系列1和系列2中，在截肢时将一根神经导管连接到坐骨神经残端，在系列1中每天对神经进行20分钟的机械刺激，持续20天。在系列2中，每天2次通过导管向神经周缘注射0.3 ml 1%利多卡因，连续20天。系列3的动物作为对照。随访时间分别为1、3、6个月。研究方法是用墨水-明胶混合物灌注血管的组织学方法。结果。在系列1中，修复过程出现了剧烈的紊乱，表现为形状改变、骨干皮质板吸收、残端畸形、骨闭合板形成缺失和微循环紊乱。在第二系列的大多数实验中，器官型残肢形成微循环正常化。3组残肢形成效果好于1组，但差于2组。结论。在无疼痛综合征的情况下，在1、3、6个月的时间内，骨干水平截肢后的骨残端保持其圆柱形、皮质骨干板的结构、微循环正常的髓管内容物、骨闭合板的形成以及修复过程的完成。残端截肢后疼痛综合征的存在，随着骨组织病理重塑的发展，扭曲了修复过程的进程。

Background. Recently, interest in blast-induced brain injuries has been increasing due to military events and the use of explosive devices in eastern Ukraine. Considering the diagnostic uncertainty regarding the specific signs of brain injury after the distant action of an blast shock wave, the danger of prognostic consequences, the increase of the cases of explosive injury number, we consider that selected for study topic is relevant. Objective. Purpose – determination of pathomorphological changes of the brain after the action of the blast wave. Methods. To solving this purpose, a retrospective analysis of 280 cases of fatal military blast injuries was conducted. We selected 6 cases for microscopic examination of the brain. For histological examination, samples were taken from different parts of the brain. Results. Analysis of 280 deaths due to explosive trauma showed that 58.9% of the dead (165) had a traumatic brain injury, and in 131 cases it was accompanied by fractures of the bones of the vault and the base of the skull. Isolated traumatic brain injury was detected in only 33 cases (11.8%). Age distribution analysis of the dead people showed that 67.5% of the dead were between the ages of 21 and 40. Histopathological analysis of brain samples from the dead allowed to identify the characteristic signs of blast-induced brain injury in the form of diffuse formation of perivascular microhemorrhages with partial or complete separation of the vascular wall from the neuropil. Conclusion. The complex of microscopic signs in the brain, namely, the separation of vascular wall from neuroglia with the formation of perivascular space, fragmentation of these vessels walls, erythrocytes hemolysis, hemorrhage in the newly formed perivascular spaces, are direct evidences of the blast wave action.

Recently, interest in blast-induced brain injuries has been increasing due to military events and the use of explosive devices in eastern Ukraine. Considering the diagnostic uncertainty regarding the specific signs of brain injury after the distant action of an blast shock wave, the danger of prognostic consequences, the increase of the cases of explosive injury number, we consider that selected for study topic is relevant. Objective. Purpose – determination of pathomorphological changes of the brain after the action of the blast wave. Methods. To solving this purpose, a retrospective analysis of 280 cases of fatal military blast injuries was conducted. We selected 6 cases for microscopic examination of the brain. For histological examination, samples were taken from different parts of the brain. Results. Analysis of 280 deaths due to explosive trauma showed that 58.9% of the dead (165) had a traumatic brain injury, and in 131 cases it was accompanied by fractures of the bones of the vault and the base of the skull. Isolated traumatic brain injury was detected in only 33 cases (11.8%). Age distribution analysis of the dead people showed that 67.5% of the dead were between the ages of 21 and 40.

Background. Medical education is based on general and specialized knowledge in the learning process, a combination of theory and practice at a medical university and is the foundation of the medical profession. But the formation of professional value orientations of future doctors remains out of consideration. Therefore, the professional training of future doctors needs the content of medical education to be improved in order to focus on the formation of professional values. Objective. To substantiate the scientific results of the experimental study of the formation of professional value orientations of future doctors. Methods. Theoretical analysis of scientific sources in order to determine the nature, content and structure of professional values of future doctors. Results. The article analyzes the results of experimental research. It is established that a promising direction to improve the quality of training of future doctors is the formation of a system of his professional values, which reveals the value position of the individual in relation to professional activities. In our study, we identified the professional value orientations of future doctors as a system of values, value orientations, meanings and attitudes to the professional activities of doctors, forming a unique axiosphere of personality that reflects the personal, professional and social orientation of the doctor. Taking into account the specifics of the doctor's professional activity, we have developed a structure of professional value orientations of future doctors. In the process of studying the structural composition of professional value orientations of future doctors, axiological, psychological, motivational, cognitive and prognostic components are identified, each of which performs a certain function. The main functions of professional value orientations of future doctors include: worldview, normative, regulatory, communicative and professional activity. The criteria of formation of professional value orientations of future doctors in the process of professional training are determined: cognitive; personal; activity. The levels of formation of professional value orientations of future doctors are highlighted: high, medium and low. The effectiveness of the organizational and pedagogical conditions and pedagogical technology of professional value orientations’ formation of future doctors determined by us is experimentally confirmed. Conclusion. The results of the experimental study showed the effectiveness of the author's pedagogical technology and its effectiveness in the formation of professional value orientations of future doctors in the process of basic training. The formed professional value orientations of future doctors were evaluated and statistically verified.

The study of structural changes of organs and tissues in the context of diabetes is one of the urgent problems of modern medicine. According to WHO, in all countries of the world the number of patients with diabetes exceeds 175 million. According to an expert estimate of the spread of this disease by 2025 will make about 300 million people. More than 1 million people with diabetes have been officially registered in Ukraine. WHO has recognized the disease as a non-communicable epidemic. The dramatic increase in the prevalence of diabetes requires a detailed study of this problem. It is established that the prevalence of diabetes increases among the population of the countries of the world depending on the region, the level of economic development of the country, gender and age. Thus, according to IDF findings, there is a tendency for the highest prevalence of diabetes among the urban (urban) able-bodied population of developing countries in persons between 40 and 59 years of age, approximately equal in both male and female. The number of patients is increasing, mainly due to patients with type 2 diabetes. Type 2 diabetes (type 2 diabetes mellitus) is a severe progressive chronic disease that is an independent risk factor for heart failure (CH) and cardiovascular complications. In the XXI century. the steady growth of type 2 diabetes and the frequency of its serious consequences is of great concern to the world medical community. It is important that at the time of diagnosis of type 2 diabetes, the prevalence of complications leading to a decline in quality of life, early disability and premature death is already high enough. Despite the presence in the fight against this disease effective drugs, modern technologies, new educational and preventive techniques, mankind loses the fight against diabetes year after year, which leads to disability due to its complications, reducing the life expectancy and quality of life of patients, loss working capacity and premature mortality. Thus, the current prevalence and incidence of diabetes and life-threatening complications suggest that there is a non-communicable diabetes epidemic in the world and in Ukraine in particular. The article represents analysis of work of numerous researchers who studied statistіcal, clinical and morphological aspects of the impact of diabetes on cardiovascular system. Main morphogenetic, morphological and clinical aspects of complications of diabetes, pathologies of microcirculation of patients with diabetes were dedicated, what makes possible to predict and detect on the early stages vascular complications in diabetes and to perform effective prevention and treatment.

Background. In recent years, the prevalence of thyroid pathologies of various origins among children in the world has reached a significantly high level. The use of glucocorticoids during pregnancy remains a debatable issue in obstetrics today, as they can both positively and negatively affect the processes of organ morphogenesis and be the cause of pathological conditions in the postnatal period. Objective: to establish the features of morphofunctional transformations during the morphogenesis of the thyroid gland of the offspring of rats at an early age in normal and after intrauterine action of dexamethasone. Methods. 108 thyroid glands of rats of 3 experimental groups were microscopically examined using histological and immunohistochemical methods, followed by statistical processing of the obtained results. Results. Against the background of high levels of total follicular thyrocytes per 1 day of life in animals that received prenatal dexamethasone, cytoplasmic expression of TgAb was expressed, which correlated with the indicators of nuclear and cytoplasmic Fox-1 expression. From the 7th to the 11th day, a decrease in the total number of thyrocytes per unit area was observed due to the accumulation of colloid in the follicles, an increase in Fox-1 cytoplasmic expression and a decrease in nuclear expression, against the background of increased proliferative activity. By day 21, Fox-1 cytoplasmic and nuclear expression were almost identical. There was a decrease in the intensity of TgAb expression in the cytoplasm of thyrocytes and its expression in the colloid, a decrease in the number of Ki-67 positive thyrocytes per conditional unit area compared with the previous observation period. Conclusion. It was found that prenatal exposure of dexamethasone causes the offspring accelerate the development of morphological structures of the thyroid gland, but functionally they are in a state of stress of both the synthesizing apparatus and the process of hormone excretion, which is expressed in the imbalance of immunohistochemical expression of Fox-1 and TgAb. Such thyrocytes with signs of disturbances in synthetic activity desquamate into the lumen of the follicles, while on the 11th day we compensatory increase in the proliferative activity of the thyroid epithelium.
