title: Study of protein components of natural peptide regulators.
abstract: Special attention should be given to the safety of drugs prepared from animal products. Industrial production of cytomedines and cytamines includes treatment of organs and tissues from young animals. Studies of preparations by methods recommended by the World Health Organization indicate that this technology guarantees the absence of infectious agents, protooncogenes, nucleic acids, and prion proteins.
