This study introduces a method for creating durable, colored anatomical plastinates using chemical reagents. The vibrant colors remain stable through the plastination process and long-term exposure, making them ideal for educational use.

Area of Science:

  • Anatomical Sciences
  • Materials Science
  • Biotechnology

Background:

  • Traditional anatomical specimens can degrade over time.
  • Preservation methods like plastination offer durability but often lack vibrant, permanent coloration.
  • Educational tools require clear, stable, and robust anatomical models.

Purpose of the Study:

  • To develop a method for producing permanently colored anatomical plastinates.
  • To assess the stability and durability of the colors used in the plastination process.
  • To create enhanced anatomical teaching and examination materials.

Main Methods:

  • Utilized various chemical reagents to color specific anatomical structures (e.g., red, blue, yellow).
  • Subjected the colored specimens to standard plastination steps: dehydration, degreasing, and silicone resin impregnation.

  • Tested color stability by exposing the finished plastinates to light and heat for over five years.

    • Main Results:

    • The chemical coloration remained stable throughout the entire plastination process, including silicone impregnation.
    • Colored anatomical plastinates demonstrated permanent coloration after prolonged exposure to light and heat (over 5 years).
    • The final plastinates were dry, flexible, odorless, robust, and highly instructive.

    Conclusions:

    • Chemical coloration is a stable and effective method for producing vibrant, permanent plastinates.
    • These colored plastinates significantly enhance anatomical education, offering durable and visually clear models.
    • The developed technique provides valuable, long-lasting resources for tutorials, examinations, and seminars.
