[Histamine-releasing activity of acrylic plastic materials].

The histamine-releasing activity of acrylic plastics (ftorax, stomacryl, ethacryl) used for denture making and maxillofacial prostheses was studied by automated and computer-aided fiber glass method for evaluating histamine release from whole blood basophils. The results indicate that some plastics made by the thermo-polymerization method (for example, ethacryl) are characterized by higher histamine-releasing activity than the plastics made by polymerization using superhigh frequency electromagnetic energy. The method is recommended for preliminary screening of new polymers intended for dentistry and for individual selection of materials with consideration for their safety and strength characteristics.
