RESUMO
The authors describe a method to prepare macroscopic serial sections of human brain in accord with the computer tomography reference lines. Whole brains were orientated after formalin fixation in a special perspex box, embedded in polyurethane filling foam (SYSpur) and cut into 5 or 3 mm thick sections.

The authors describe an approach to make anatomical dry preparations from voluminous hollow organs (gastro-intestinal tract, urinary bladder etc.) by "foaming-out" with polyurethane-solid foam (SYSpur). Injections of silicon resin material into intestinal veins or arteries increase the value of demonstration by relief like featuring of the vessel system. The corrosion of "foamed-out" intestinal section after injection of Kallocryl M is presented as a new method. The preparations possess an improved stability in comparison with simple corrosion -- preparations from hollow organs. Furthermore, the solid foam matrix may be used as a topographical reference.
