[Methods of treating tissues with subsequent embedding in paraffin]

Two methods of tissue processing with subsequent embedding into paraffin are proposed. In the first method a mixture of 70% of gum turpentine and 30% oleoresin is used as the main solution. In the second one a mixture of gum turpentine, castor oil and cedar balm is used as the main solution. The treatment of the tissue pieces takes 23 hours. These methods permit avoiding the artifacts connected with tissue dehydration and obtaining histological slides of a high quality.
