    Abstract:
    In vitro studies of phagocytosis-stimulating effects of interferon preparations differing in their origin and mode of purification were carried out with blood cells of dermatosis patients and healthy donors. Native preparations and preparations purified by sparing methods (alpha-interferon for intranasal administration and alpha-interferon for injections II) were found the most active: they induced a significant elevation of the activities of individual cells and of the count of actively phagocytizing cells. Phagocytosis-stimulating effect of well purified interferon preparations is essentially reduced. Recombinant alpha 2-interferon preparation has shown no such activity. A dose dependence of the effect of interferon preparations on blood neutrophil phagocytic activity has been revealed. The highest phagocytosis-stimulating effect of the above interferon preparations was observed in patients whose blood polymorphonuclear leukocyte phagocytic activity was essentially reduced.
