PRODUCCIÓN DE PIEZAS ANATÓMICAS PARA LA ENSEÑANZA EN LA ANATOMÍA VETERINARIA USANDO LA IMPREGNACIÓN CON POLIETILENGLICOL (PEG). COMPARACIÓN CON EL METODO DE PLASTINACIÓN

Resumen

To explore an alternative for plastination, in this study impregnation with polyethylenglykol (PEG) was used for production of durable anatomical specimens for teaching in veterinary medicine. The specimens were fixed in 2% formaldehyde and impregnated in a vacuum with a low-pressure of 15 millibar. By using this technique moveable joint specimen, hollow organs, colour injected specimens, and parts of organs were produced for didactic purposes. The PEG-impregnated specimen has several advantages, e.g., can be stored in plastic bags or boxes, are resistant against fungi and bacteria, and produce no-skin irritation, and has been successfully used in veterinary anatomy teaching.
