[Schummer's plastoid corrosion procedure in scanning electron microscopy of blood vessel systems].

In 1951 Plastoid was introduced into the anatomical reconstruction technique of vascular system by Schummer. Now the present study shows Plastoid as a casting-material even for scanning electron microscope-technique superior to other resins used for this purpose. Its special benefit is well-founded in intensive temperature stability, variable polymerization time, changeable viscosity and last not least in his low priced application-mode. Plastoid corrosion-casting models exhibit endothel nuclear impressions and cell borders, smooth muscle layers ("Plastic-Strips") (Castenholz et al. 1982) and inner elastic elements of blood vessels in scanning electron microscopy.
