title: [New fixative for the biological material].
abstract: New non-toxic fixative for biological material is patented, that is based on aqueous solutions solutions of bivalent copper cations. Optimal molarity of fixative solution (0.2 M) was established experimentally. The method proposed is selective in demonstration of tissue structures using Bielschowsky-Gros impregnation of material by silver nitrate.
