description |
Sheet plastination is a technique for tissue slices
preservation that gives real anatomical specimens and
its slices considered as a good reference in cross section
anatomy as well as in radiology. This research aims to
compare the shrinkage area between plastinated human
brain slices using two different dehydration methods on
a single human cadaver brain. This study included using
of nineteen slices of one human brain. The brain was fixed
in 10% formalin for three months, washed and cut in two
halves in the sagittal plane. Both brain halves were sliced
at a thickness of 3mm. From the left half 9 slices were
selected for the standard method of dehydration (20°C for
one week for full process the concentration of acetone was
95% and 100% in two steps) and 9 slices from the right
half for the revised method (-25°C for two weeks for full
process the concentration of acetone was 80%, 85%, 90%,
95% and 100% in five steps). To measure the surface area
for each slice, it was put on a A4 sized white plastic board
measuring 210 × 297 millimeters and a picture was taken
before dehydration (before plastination) and after curing
process (after plastination) by using a normal digital
camera 13.0 megapixel (MP). The left and right brain slices were then immersed at 20°C for one day in P40 resin only, and then impregnated at room temperature (20°C) for 24 hours under vacuum (50mmHg) condition.

The statistical analyses were carried out by Microsoft Excel t-Test. These results were considered significant at p < 0.05
level. In conclusion, the revised dehydration method gives
less shrinkage rate than standard method in brain sheet
plastination. |
