Abstract:
PURPOSE: A method for restoration and preservation of an immersion type biological sample for permitting maintenance of a body color of a biological sample for a long period time and restoration of a body color of a decolored biological sample to its original state and then preservation is provided which permits semipermanent preservation of the body color of the biological sample and reutilization of conventional biological samples without the necessity of fabrication of a new biological sample. CONSTITUTION: A body color composition for restoration and preservation of an immersion type biological sample contains 0.3 to 2 parts by weight of benzyl alcohol, 0.3 to 2 parts by weight of sodium chloride, 15 to 25 parts by weight of formalin and 5 to 15 parts by weight of glacial acetic acid, based on 100 parts by weight of water. The restoration method comprises: preparing a body color composition similar to the body color of a biological sample; dyeing the biological sample with the body color composition; fixing the biological sample; and immersing the fixed biological sample in a preservation liquid.
