Effect on Behavior in Humans With the Administration of Taraxein

Work in progress centered about the isolation of taraxein from the serum of schizophrenic patients and its administration to monkeys and human volunteers is presented. The taraxein was extracted from a variety of schizophrenic patients in 4 institutions and administered on 17 occasions to nonpsychotic human volunteers and on one occasion to a schizophrenic patient in remission. Several additional studies are planned or in progress and we expect that in the near future it will be possible to present considerably more information.
