Abstract: The invention relates to the use of pure histones H1, H2A, H2B, H2A:H2B, H3 as hormonal or hormon-like active substance for the preparation of pharmaceuticals for the immuno-therapy, for the therapy of endocrine disturbance and for cancer therapy. Instead of the histones also their evolutionary variable sections or at least one partial section of at least five aminoacid residues of at least one evolutionary variable histon section can be used.

Abstract: Biologically active substance with standardizable hormonal activity, containing in a physiological medium at least one histone, particularly at least one histone H2 or an active area of said histone with immune system immunostimulating and/or endocrinological properties. Utilization of histones and/or segments of histones for producing such a preparation for medical purposes. Said histones may be extracted from biological starting materials, for example calf thymus. Since H2A and H2B histones of oxen and humans are identical, ox histones may also be used for such a preparation for human medical purposes. The preparation according to the present invention may also contain only the variable evolution segments or part of at least one H2 histone. The invention is based on the fact that the biologically active area of an immunostimulating or endocrinologically active histone is located in the variable evolution histone segment. The preparation according to the present invention may be used in immunotherapy.
