One to six months after grafting, symptoms were improved significantly for 1 to 3 grade. Among them, 2 patients resumed nearly normal daily activities. Long-term follow-up showed that the symptoms were not improved satisfactorily in some patients. It is considered that careful selection of patients, administration of amantadine, and co-grafting of Schwann's cells which prompts the survival of chromaffin cells are essential to better results.展开更多
