Prevention of spontaneous autoimmunity to DNA in NZB/Swiss mice by treatment with natural double-stranded RNA.

Data are presented demonstrating the prevention of spontaneous autoimmune disease in NZB/Swiss mice treated natural double-stranded RNA. The successful treatment of animals was followed both by improvement in clinical manifestations and by the migration inhibition test performed with DNA as antigen. The reasons for the successful employment of natural double-stranded RNA are thought to be in its physicochemical properties.

Interferon-hyporesponsiveness in mice in connection with dose interval and site of administration of Newcastle disease virus. Reflexion in serum complement levels.

Intraperitoneal administration of Newcastle disease virus (NDV) resulted in enhanced serum levels of complement not accompanied by an increase of interferon levels, when measured at 24 hours' intervals. On the other hand, intravenous injection of NDV caused a drop of complement levels of short duration with an accompanying increase of interferon levels. Hyporeactivity to induction of serum interferon could not be achieved by intraperitoneal administration of NDV, but an incomplete hyporeactivity could be achieved by intravenous administration of NDV. It might be assumed that production of interferon in mice occurs in different separated compartments depending on the route of inoculation of the inducer.
