PREPARATION POSSESSING ANTIVIRAL AND IMMUNOCORRECTING EFFECT Russian patent published in 2005 - IPC

Abstract RU 2262946 C1

FIELD: medicine, biopharmacology, immunology.

SUBSTANCE: invention relates to manufacturing curative-prophylactic preparations based on leukocyte interferon and natural cytokines. The preparation based on complex of natural cytokines is prepared by induction of human leukocytes with Newcastle disease virus of strain "H". Indicated complex of natural cytokines is prepared by at least two treatments of leukocytes before induction stage with virus with the same natural complex of cytokines prepared in previous stage of induction. Complex is purified from foreign proteins of inductor and comprises 10⁴ IU of antiviral activity of human interferon-alpha in one ampoule, not less, and cellular cytokines, phosphate buffer for maintaining pH 6.9-7.5, sodium chloride and mannitol. The end product is lyophilized for preparing the injection preparation. Invention provides increasing activity of the preparation and to retain the natural complex of cytokines.

EFFECT: improved preparing method, valuable medicinal properties of preparation.
