HEALTH DISORDER ASSOSIATED WITH PERMANENT DISABILITY AS THE SIGN OF BODILY HARM.

OBJECTIVE: The aim: The paper is aimed at creation of the procedure and criteria for determining a health disorder associated with permanent disability as a sign of serious bodily harm. PATIENTS AND METHODS: Materials and methods: To identify the problems faced by forensic medical and judicial practice in determining a health disorder associated with permanent disability, we studied more than 100 criminal proceedings from 2007 to the present time. RESULTS: Results: Ways to further improvement of the procedure for conducting expert studies on health disorders, associated with persistent loss of general ability to work as a characteristic feature of the bodily harm have been found to avoid errors in forensic medical and judicial practice. The issues of conducting forensic medical examinations to determine the degree of loss of general ability to work remain unresolved. The lack of joint research projects conducted by both medical and legal scientists leads to the polysemy and different approaches in the stating of certain concepts that are the subject of study of both medical and law sciences. Currently, the definition of the offence against health is debatable and the issues of criteria for determining such damage are not completely settled to date. CONCLUSION: Conclusions: We consider the development of the Procedure and Criteria for determining the degree (in percentage) of the permanent loss of general ability to work of victims of criminal offences, established by forensic medical experts, is crucial.

Microscopic structure of albino rats' small intestine.

OBJECTIVE: Introduction: The small intestine of albino rats is a transitive canal between the stomach and the cecum that is closely located from each other, reaches a length of one meter, which in comparison ratio to body weight significantly exceeds the corresponding segment in humans. The aim: The paper is aimed at thorough histological study of the wall and structure of albino rats' small intestine mucosa. PATIENTS AND METHODS: Materials and methods:30 mature albino male rats were involved into the study. The specimens of albino rats' small intestine, fixed in 10% neutral buffered formalin solution, have been studied. The study was carried out using conventional histological methods for obtaining serial paraffin sections stained with hematoxylin-eosin. Epoxy plastination of individual tissue samples of the small intestine was performed. Subsequently, polished thin sections were made, stained with 1% methylene blue and 1% borax solution. The obtained specimens were studied on the "Konus" light microscope equipped with Sigeta DCM-900 9.0MP digital microphoto attachment with the Biorex 3 software adapted for studies of such type. RESULTS: Results and conclusions: For the first time in the practice of histological study of the epithelial covering of the mucous membrane of the small intestine, attention is drawn to the specific pattern of its organization on the intestinal villi. It has been found that epithelial covering consists of alternating cluster epithelial aggregations separated by fissured depressions. Since no mentioning about them has been found in the publication, these cluster aggregations of enterocytes can be called epithelial buds of the intestinal villi. Consequently, it can be concluded that with the exception of some specific morphological features, the small intestine of albino rats is homologous to human one by its histological structure, which means that it can be used as a model for various experimental studies.

Features of angioarchitecture of the albino rats stomach and small intestine.

OBJECTIVE: Introduction: The stomach and small intestine are important organs of the digestive system and, to date, they are the subject of research by morphologists, endocrinologists, immunologists, gastroenterologists, and other researchers. The aim: The paper is aimed at the study and systematization of the features of angioarchitecture of the albino rats stomach and small intestine. PATIENTS AND METHODS: Materials and methods: The study based on the injection of the blood vasculature of abdominal organs of 20 albino male rats with 5% gelatin solution, colored with filtered black ink, was performed. The specimens were subject to photographing from different aspect angles in their original state, and then, after dehydration in alcohols with the transition to pure acetone, they were embedded in the epoxy. Photographing of the obtained specimens was made by a digital camera, as well as a binocular magnifier MBS-9, equipped with a digital photoattachment Sigeta DCM-900 9.0MP. RESULTS: Results and conclusions: The results of injecting of blood vasculature of albino rats' gastrointestinal tract with ink mass clearly demonstrate the specific difference in the intraorganic angioarchitecture of its different regions, which depends entirely on their functional purpose in the digestive process. In the stomach, the highest concentration of blood microvessels is in its glandular part, which is explained by the increased nutrient needs of the secretory process of the gastric glands, while the mucous membrane of its fundus (pre-stomach) contains a scattered network of exchange microvessels that only promote the process of regeneration of the stratified squamous (partially keratinized) covering epithelium. In the small intestine, the typical principle of the organization of the microvasculature of its mucous membrane is somewhat modified in the duodenum, which is associated with the presence of mucous (Brunner's) glands in it, as well as in those sites (starting from the duodenum) where the group lymph nodes (Peyer's patches) are localized.
