【 摘 要 】

:The formalization is the main form of body and anatomic conservation, mainly due to its low cost. The technique is based on the use of formaldehyde (5-20%) as fixative and preservative. However there are several negative factors on their use, unpleasant smell, browning, weight gain and stiffness of parts and serious environmental problems if disposed of incorrectly, and is a product classified by the International Agency for Research on Cancer as highly carcinogenic. There are several options to replace formaldehyde and glicerinação is one of them, whose which will be treated in this work. Glycerin dehydrates the cell and acts as antifungal and antibacterial, and has many advantages compared to formaldehyde. But its cost is still high and this explains their limited use in the anatomy lab. This work aims to show the advantages of using glycerin in relation to formaldehyde and propose a possible replacement of this carcinogen to preserve the health of students, staff and teachers within the laboratory, and allows a more pleasant environment for learning.Index
