[Cerebral auto-antigens in the serum of schizophrenic patients].

Brain autoantigens in the blood of 200 schizophrenic patients were investigated. It was established that the introduction of brain autoantigens caused the formation of antibrain antibodies in the animals. The brain autoantigen, limitted by the species, is also present, and there is a possibility of autoimmunization by each of them. It is shown that the autoantigen which is connected with the species of the brain, is stable to organic dissolvent activity in the paranoid form of schizophrenia (87.5%) and in the malignant and shift-like form (20%). In the other forms of schizophrenia and also in epilepsy and viluy encephalitis its inactivation is marked. The qualitative heterogeneity of brain autoantigen in different forms of schizophrenia is suggested.
