[Dry erythrocytic diagnostic agent for the determination of antiglobulins].

Dry erythrocytic diagnostic agents were obtained under experimental conditions for determination of antiglobulins forming in the organism of man and animals under the effect of serum preparations from the blood of horses and homologoum immunoglobulins. A study was made of the sera of 100 patients with tick-borne encephalitis treated with heterologous and homologous immunoglobulins of directed action; in response to the administration of horse gamma-globulin antiglobulins (in titres below 1 : 10000) appeared in the serum; they circulated in the blood for long periods and inhibited the accumulation of hormonal antibodies to the causative agent; in the majority of cases a high level of antiglobulins to the foreign protein correlated with the presence of remote side-reactions of the serum sickness type. In patients treated with immunoglobulin of human origin antiglobulins were determined in low titres, disappeared from the blood in 15--20 days and did not hinder the accumulation of antihemmagglutinins to the tick-borne encephalitis virus.
