EFFECT OF TRANSPLANTATION OF HUMAN FETAL TISSUE ON CENTRAL-NERVOUS-SYSTEM FUNCTION IN PATIENTS WITH THE POSTCASTRATION SYNDROME

Electrical activity of the brain was studied in 45 women after total o ophorectomy in a state of calm alertness and in functional overload be fore and after transplantation of human fetal tissues. Pretransplantat ion studies showed alpha-rhythm disorganization, alpha-activity polyrh ythmicity, a tendency toward high-frequency rhythms, and a disordered process of internal synchronization. Studies carried out after human f etal tissue transplantation showed adjustment of the cortex-stem relat ionships, a reduction of the alpha-rhythm index, and an increased beta -activity index. Reactions to Light stimuli and the function of the ce rebral cortex improved in the majority of patients after transplantati on, this being manifested in appropriate reactions to afferent stimula tion. However, by the 6th month posttransplantation electrical activit y of the brain was virtually the same as pretreatment.
