Kidneys from five month-old mixed-breed pigs were collected and 2-3mm thick longitudinal slices were prepared for viewing sub-gross anatomy as fresh tissue or as routinely plastinated tissue with and without degreasing. Standard cold silicone plastination procedures were used. Sliced fresh tissue and cured plastinated specimens were placed on a glass plate and back-lit to evaluate anatomical detail. All specimens yielded similar anatomical detail. However, degreased, plastinated specimens yielded the most anatomical detail. These thin silicone slices produce a durable permanent record similar to epoxy sections without the need for casting slices.
