[Methods for long-term storage of anatomical demonstration objects].

2 methods for longterm conservation of anatomical objects have been described. The former concerns the use of methylmethacrylate (the plastic material) for embedding of anatomical objects into different forms. The 2nd method uses the same plastic material for impregnation of anatomical objects. The authentic anatomical models produced by the both methods possess very good demonstrative features. They are solid and cheap.
