Construçäo de um micrótomo de congelamento a partir da adaptaçäo de um micrótomo de parafina / Building of a frozen microtome by the adaptation of a paraffin microtome

A microtome for frozen sections was developed using the facilities and equipment avaiable in our country. The requirements for making it were: 1) fast frozen of the tissue; 2) easy hystological procedure; 3) no necessity of long period for preparation of the tissue for histological procedure, and 4) low cost for making.
