ABSTRACT
Standard formalin embalming is the most important of all work with cadavers in anatomy laboratories, as it keeps the tissue strict, insoluble and protected against deterioration. The most commonly used substance for preservation of cadavers and tissues is formaldehyde, a preservative because it is inexpensive, easy penetration and fast action on the parts. Another substance used is glycerin with rapid action and dehydrating fixative, used also for the preservation of anatomical specimens. This study aimed to compare two techniques that use glycerin in conserving parts of the central nervous system of animals. We evaluated the properties and fixing of conservative solutions applied. The two techniques chosen for this work were the Giacomini and Torres method. In the Torres method, the tissue was more flexible and easy to visualize the structures. In the Giacomini method, the tissues were dark colored, rigid, with little flexibility. This technique requires a shorter time of immersion, compared to Torres. We conclude that the most appropriate method for application in laboratories of anatomy and applicability in practical lessons is technique was Torres.
