ABSTRACT
Recently the reports of the autologous grafting of adrenal medullary tissue into the brain of parkinsonian patient have given the wide attention to the neurosurgeons as well as other clinicians, because the current therapeutic modalities are either imperfect or palliative. Although neural grafting of adrenal medullary tissue of fetal brain which can supply the dopamine seems to be a ideal form of treatment theoretically, many problems must be overcome for this approach to be a routine procedure. Authors made the rat parkinsonian model by destroying the substantia nigra and nigrostriatal fiber selectively with 6-OHDA. And abnormal behaviors and growth patterns were observed and studied using rotometry, T-maze and metabolic cage. With the results, some parameters which would be useful in further experiments could be established.
