We studied the morphological features of the jejunum and ileum in middle and heavy goose breeds. The geese under six month of age of Gorkovskaya and Legart breeds were used in our research. Geese of a heavy breed had a large intestinal mass, length of the jejunum and ileum, thickness of the mucous membrane of the ileum, and a smaller thickness of the muscular tunic of the jejunum. Legart geese had greater villi density and crypt depth in the jejunum and greater height and density of the villi, the width of the crypts, and the ratio of the height of the villi to the depth of the crypts in the ileum. In all the guts of heavier geese, the density of crypts was lower. The geese of the heavy breed had larger number and area of the ganglia of the mental plexus and smaller number and area in the submucosa in the jejunum, while they had larger area of the ganglia of the submucosal plexus in the ileum. The number of argyrophilic and argentaffin apudocytes in the jejunum of geese of different breeds did not differ, when the Legart breed geese had lesser quantity of apudocytes in the ileum.

In recent decades, diseases of the digestive system that require immediate, both therapeutic and surgical treatment, have become widespread, and it is therefore a natural task to find new and optimize existing technologies and methods for correcting the above-mentioned nosologies. Preclinical studies of such developments are conducted exclusively on laboratory animals and knowledge of the morphological features of their structure for further comparison with the morphology of similar human organs is an urgent task of modern medical and biological science. The purpose of the study was to study the structural organization of the ileum of rabbits in comparative species and to obtain control data on its morphological features. Adequate research methods were used in the work according to the set goal, namely: histological, histochemical, electron microscopic, morphometric and statistical and biopsies of the ileum of 10 rabbits were studied. The correctness of the distribution of traits by each of the variations obtained, the average values for each trait studied, standard errors and standard deviations were evaluated. The significance of the difference of values between independent micrometric values in the normal distribution of features was determined by Student’s criterion. The paper describes the main structural components of the ileum of rabbits and compared with similar structures of the human ileum. The ileum of rabbits, as in humans, has been determined to have four membranes: mucous, submucosal, muscular and serous. The mucous membrane is constructed from the epithelial layer, which is located on the basement membrane and the muscular plate and contains cellular elements (exocrinocytes, enterocytes of various kinds, elements of the diffuse endocrine system associated with the mucous membrane, intraepithelial lymphocytes), blood and lymphatic vessels and nerve endings. The submucosa is composed of loose fibrous connective tissue, which contains collagen and reticular fibers, elements of diffuse lymphoid tissue, blood vessels, and nerve endings. The muscular and serous membranes are constructed in the same way as in the human ileum. Thus, after the study, it was determined that the morphological organization of the ileum of rabbits at the optical and electron microscopic levels has general patterns of structure similar to those in the ileum of the person.

The work is a fragment of the research project “Pathogenetic features of the allergic and inflammatory processes course and their pharmacocorrection”, conducted by the Department of Pathological Physiology, Danylo Halytskyi Lviv National Medical University (state registration No. 0116U004503). The aim of the work: to study the morphological features of the colon in the dynamics of the development of experimental acute peritonitis on the background of streptozotocin-induced diabetes mellitus. Materials and Methods. The experiment used 48 white male rats. Diabetes mellitus in experimental animals was simulated by a single intraperitoneal injection of streptozotocin (Sigma) at a rate of 60 mg/kg, acute disseminated peritonitis – the introduction of 0.5 ml of 10 % filtered fecal suspension into the abdominal cavity. A morphological study of the colon in animals removed from the experiment on the first, third and seventh days of acute peritonitis on the background of concomitant diabetes mellitus was performed. Results and Discussion. Morphological examination of the colon of animals on the first day of experimental acute peritonitis in conditions of concomitant streptozotocin-induced diabetes mellitus revealed an increase in the size of the crypts due to stroma edema and lymphohistiocytic infiltration, slight perivascular edema in the subclavian edema. On the third day, thickening of the mucous membrane of the colon, a sharp increase in the depth of the crypts, uneven blood supply to the vessels in the submucosal layer with a predominance of perivascular edema were verified. On the seventh day, a decrease in the thickness of the mucous membrane due to the expansion of the crypts was visualized. Part of the epitheliocytes was in a phase of increased secretory activity, the other part was dystrophically altered, which stimulated increased lymphocytic and histiocytic infiltration. These changes were accompanied by activation of reactive processes and hyperplasia of lymphoid follicles on the first day of peritonitis on the background of streptozotocin-induced diabetes mellitus, and as the severity of purulent inflammation – hypoplasia of the lymphoid tissue and a decrease in local reactivity(the third and seventh days of the development of acute peritoneal burning in conditions of combined pathology).

Impacted teeth are rather common and complex dentofacial anomaly, which requires a balanced approach not only in differential diagnosis of its specific nosological form, but also in a choice of rational treatment methods. Taking into account the multi-factor nature of conditions formation for delay of teeth eruption, an approach to treatment should be directed towards guiding links of pathogenesis. The aim of the study is to increase effectiveness of surgical and orthodontic treatment of patients with impacted teeth of anterior maxillary region by studying morphological features of mucous membrane over impacted teeth, depending on conditions of their positioning. A group of 21 individuals aged from 15 to 17 years was formed to evaluate objectively the results of our work. Clinical situation in all the patients was the same according to diagnostic criteria as presence of impacted maxillary canines and medium level of vertical depth of impaction (in alveolar process); root formation: completely formed, with deviation of longitudinal axis of impacted tooth from correct axis of eruption from 15º to 45º. During further analysis, clinical subgroups were identified depending on conditions of impacted teeth positioning in vestibular-oral direction. Moderate dystrophic changes in stratified squamous epithelium, moderate sclerotic changes in papillary layer of lamina propria were found based on findings of microscopic structure of mucous membrane over palatal positioning of teeth. During investigation of morphological structure of mucous membrane over labially positioning of impacted teeth, there were phenomena of hyperkeratosis, an increase in the number of intraepithelial lymphocytes, presence of epithelial cells in the basal layer with signs of hydropic degeneration. In papillary layer of lamina propria of mucous membrane, sclerotic changes were observed, which were more pronounced in comparison with palatal positioning of impacted teeth. Complex analysis of results of morphological studies showed that in mucous membrane positioning over impacted teeth there is deterioration with anemia in filling conditions of microcirculatory bed, discirculatory disorders, which leads to formation of ischemic zones and development of dystrophic and sclerotic processes. Morphological features of the structure of mucous membrane over impacted teeth is an important to consider while planning surgical and orthodontic treatment, and to some extent, it is possible to adjust management tactics of such patients, taking into account labial or palatal positioning of impacted teeth.

The purpose of the research was to determine the morphological features of the mucous membrane of the large intestine of patients with UC depending on the age of patients. A comparative analysis of the incidence and type of UC of patients with early onset and late debut of the disease was performed. It has been stated that for patients with a debilitating post-traumatic disorder, the left ventricular and total forms are characteristic; in patients with late debut, the distal form of UC predominates. The main trends in the activity of UC in patients with early onset and late debut have been determined. In the analysis of the degree of activity of UC revealed that in patients from 50 years of age and older, with the late debut of the disease, the first one is mostly found to be the least degree of activity, the second – the middle and the third – the high degree, they are found to be less likely. In turn, in patients under 50, the second and third stages of the disease are most often noted. Another component of the main characteristics of the UC was the histological changes of the mucous membrane of the large intestine. Thus, the conducted studies allowed to state that the number of PAS-positive substances in mucus is significantly higher in patients with distal and left-sided UC. In patients with UC there is a marked mucosal intestinal mucosa of qualitative and quantitative composition of mucus. These changes were characterized by a decrease in MUC2 as the disease progressed, as well as levels of MUC4 and TFF3. In patients with early onset of NSC, there is a more intense reduction in the number of mucins and TFF3 already with a minimal activity of UC associated with low levels of mucin from the intracellular mucus and indicates a more aggressive course of it. At the same time, patients with a late debut revealed a sharp decrease in the number of MUC2 and TFF3 with high activity of UC.
