摘要:

Plastination is a unique technique of tissue preservation developed by Dr. Gunther von Hagens in Heidelberg, Germany, in 1978. In this process, water and lipids in biological tissues are replaced by curable polymers which are subsequently hardened, resulting in dry, odorless and durable specimens. In neuroanatomy silicone and polyester resins are used. Silicone rubber is used for whole brains and brain dissections resulting in natural looking specimens. Polyester resin is used for brain slices resulting in an excellent distinction between gray and white matter. The silicone S 10 standard technique and the polyester P 35 technique are described in detail. The advantages of plastinated specimens in neuroanatomy teaching and research are discussed.

摘要:

A database of plastinated materials was set up and distributed with a CD-ROM on the Internet. A total of 197 specimens, prepared at the Medical Museum of the University of Tokyo between 1991 and 1995, were catalogued in the database on a personal computer with commercial and original software. The database was originally designed to catalogue anatomical specimens and drawings for curators and researchers, but it also services as a worldwide digital museum.

摘要:

Volumegraph, which is an improved version of the parallax panoramagram, has been studied as a method of stereophotography of a plastinated human body specimen. The volumegraph provides a steric view of the specimen in a natural color appearance. The potential advantages in using the volumegraph for the presentation of anatomical specimens are discussed taking account of its technical details.

摘要:

Since the introduction of the plastination process by von Hagens [Anat Rec 194/2: 247-256, 1979], the cost of acetone used for the dehydration step has been considered an important factor in the cost of plastination. We have developed a three-step method that permits the reuse of acetone. The first step simply consists of storing the contaminated acetone in the freezer and separating the congealed fat by filtration. The second step is vacuum distillation of the acetone and can be conducted with the freezer and vacuum pump (found in any plastination laboratory) with just a few additions. It produces 95-97% pure acetone. The last step uses a desiccant to take away the residual water from the distilled acetone and brings the purity to 99.5%. With this method, we have reduced the amount of acetone to be purchased to a minimum and completely eliminated the cost of discarding used acetone. In addition vaporized acetone released during the impregnation step of plastination is recaptured.

摘要:

Conventional lifting gear based on steel components can be safely used in a laboratory where acetone is used provided that: (a) the circumstances under which significant amounts of acetone vapour will be present are known and can be controlled and (b) operating practices are imposed to prevent the use of the lifting gear at times when acetone vapour may be present in explosive concentrations.

摘要:

As a concerted move toward closer integration of the clinical and preclinical aspects of the undergraduate medical curriculum at the University of Auckland, the Department of Anatomy with Radiology has implemented a number of clinical procedures, pathological observations and diagnostic methods into the course resulting in a structured program of clinically based teaching of gross anatomy to second- and third-year medical students. The recently developed method of El2 epoxy resin sheet plastination of sectioned cadaver specimens has expanded the learning process twofold, firstly as a developmental microscopy teaching aid enabling us to link histological slides directly to gross anatomical specimens and secondly as a radiographic training tool in the correlation of clinical imaging techniques of magnetic resonance (MRI) and computed tomography (CT) with the teaching of gross anatomy. The direct comparison between El2 serial sectioned cadaver specimens and the equivalent MRI and CT images provides the student with a much clearer understanding of anatomical structures in relation to clinical diagnosis.

摘要:

Plastination is a process whereby the tissue water and part of the tissue fat of anatomical specimens is replaced with a curable polymer. Several variations of this technique are available, depending on both the type of specimen and polymer being used. In this study, the efficiency of BIODUR® PEM 11-prepared cross sections as a teaching aid for radiographic anatomy is investigated. A human cadaveric head was scanned on a magnetic resonance (MR) imager, recording images in a coronal plane of ∼6 mm in thickness. Corresponding slices were then taken of this head and plastinated by the BIODUR PEM 11 method. In general, a good correlation existed between the plastinated sections and the MR scans. The plastinated slices displayed superior differentiation between musculature compared to the scans. In conclusion, the plastinated sections, used in conjunction with the MR scans, are a valuable tool in learning radiographic anatomy. Additionally, BIODUR PEM 11 is a viable alternative to plastination by other metho

摘要:

Sheet plastination is currently used to produce anatomical slices of different body structures, allowing one to study and teach their topography in an anatomically correct state. Correlation with computed tomography (CT) and magnetic resonance imaging (MRI) techniques gives more insight into their anatomy. Using two female cadaver pelvises CT and MRI were performed. One pelvis was used to prepare 2-mm-thick coronal plastinated slices according to the technique described by von Hagens. We found a good overall correlation between plastinated slices, CT and MRI images. This combined approach provides a unique anatomical insight and is a valuable addition to other teaching tools used by medical students, radiologists and anatomists.
