Acquirements of the methods of the dissection in water and the CT-imaging

By Tomokazu kawashima (Tokyo Women's Medical University)

Period of visit: 26th April 2005 - 24th May 2005.

The main aim of this visit to the Institute for Zoo and Wildlife Research (IZW) in Berlin, Germany, is to obtain the macroscopic anatomical technique for the flesh materials. This method is very convenient for making a skeleton after a dissection. For obtaining the method, a vocal tract of a male Saiga was chosen because this field was main theme of my supervisor, Dr. Frey in IZW.

 The dissection was mainly examined using a scissors and forceps. Consecutive dissection steps were documented by digital camera. First, we carried out a non-destruction analysis of the specimen by mean of CT scan before a dissection. In this analysis, the material was scanned 1.2mm thickness by spiral CT and these data were reconstructed. Next, we dissected the Saiga macroscopically in water using a scissors and forceps.Consequently, the anatomical differences between the CT-data and real structure were recognized. In addition, It seems that this method is not suitable for dissection of the peripheral nervous system.

 However, these CT data of the skeleton and the cartilage are useful as a reference before a dissection.
