[The neurotropic and autoimmune activity of the serum of patients with psychoses of old age and patients with schizophrenia].

In order to define the specificity of neurotropic and autoimmune activity in blood serum of schizophrenic patients the authors studied the existence of such biological signs in another group of patients with mental disorders of a nonschizophrenic etiology: Pick's and Alzheimer's disease. It was established that to neurotropic and autoimmune activity the blood serum of atrophic patients do not differ according to these signs from schizophrenic patients. At the same time it was established that in the nonschizophrenic group the neurotropic and autoimmune activity intercorrelated. A high neurotropic activity can be seen in those patients who display antibrain antibodies in the blood. In the group of schizophrenic patients such correlations were not demonstrated. It is assumed that the neurotropic and autoimmune processes in the organism of schizophrenic patients develop independently.
