BARRIENTOS PENALOZA, José Manuel et al. CADAVERIC PIECES PRESERVATION OF NERVOUS CENTRAL SYSTEM WITH POLYESTER RESIN. Rev. Méd. La Paz [online]. 2014, vol.20, n.1, pp.34-39. ISSN 1726-8958.

Through human history, study of the human body is a priority for the acquisition of knowledge about their functioning and disease, so cadavers have been considered the best way to study, and with the evolution of science techniques have been developed to preserve its structure, so as to maintain intact over time, and of comfortable handling. At the University Nuestra Señora de La Paz (UNSLP) has come to use the polyester resin as experimental technique, with this easy to play and moderate cost relative to the other techniques with synthetic resins. Works were performed including polyester resin cuts brainstem cerebral hemispheres, cerebellum and spinal cord of human specimens. Was used orthophthalic polyester resin, accelerator, catalyst, release agent PVA resin, glass and silicone molds for the inclusion of parts. It performs the lamination procedure 20 cuts, and obtaining complete structures preserve 4 gross anatomy for over 9 months. The use of this technique in preserving anatomical specimens is simple, high durability and low cost. This form of preservation generates, in addition to traditional dissections, students have a significantly higher number of anatomical preparations available for study and research. The polyester resin plasticized cadavers used in Central Nervous System at the UNSLP, has proven to be an economical and useful technique that can preserve the pieces without altering their morphological patterns, which benefits the student medicine, providing dimensional cadavers easily manipulated.
