MODERN METHODS OF THE PRODUCING OF CORROSIVE ANATOMICAL PREPARATIONS

Abstract

One of the pressing modern problems of teaching morphology is to make the development and teaching of human anatomy as visual as possible. The organs demonstrated during the study of this discipline must retain their natural shape and size. The quality of the resulting preparations depends on the development of technologies for influencing biomaterial, its preservation and embalming. An accurate and visual preparation is the most important tool for demonstrating normal and pathologically altered organs and tissues. The purpose of this review is to analyze the literature data on modern methods for manufacturing corrosive anatomical preparations. The materials for the review were sources of anatomical literature devoted to the issues of anatomical technology, conservation and production of anatomical preparations for teaching students and museum affairs. The work highlights the history of the development of methods for manufacturing anatomical preparations for use in educational demonstration purposes. A detailed analysis of data on currently used methods for producing corrosive preparations was carried out. The advantages of corrosive preparations and polymerizing compositions in comparison with preparations made using wet fixation and plastination methods are shown. A comparative analysis of the characteristics of known polymerizing compositions is presented. The prospects for the development of the corrosion method and its use for the clarity of teaching in educational institutions of medical and biological profiles, as well as the study of three-dimensional configurations of organs and vessels when planning surgical interventions, are determined. The main promising directions for improving the corrosion method are the selection of polymerizing compositions that are rational in their properties, the development of technical devices to facilitate the filling of vascular beds with solutions, as well as other tubular and hollow organs and structures with a polymer solution. Taking into account the development of clinical anatomy and the growing interest in the individual characteristics of organs and their typical anatomy, this method can be used to visually study the variant anatomy and blood supply of complex parenchymal organs.
