PRODUCTION OF ANATOMICAL SPECIMENS FOR TEACHING PRACTICE IN VETERINARY ANATOMY BY MEANS OF POLYETHYLENE GLYCOL (PEG) IMPREGNATION. A COMPARISON WITH THE METHOD OF PLASTINATION
H.E. König1, A. Probst1, H. Dier1 and M.-C. Sora2*
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.
Key words: polyethylenglykol (PEG), durable specimens, teaching, veterinary anatomy.
