  • Look Inside

C 57 BL/6 mice show decreased dopaminergic fi-bers and dopamine concentration in the striatum following systemic injection of 1-methyl-4-phenyl-1, 2, 3, f-tetrahydropyridine (MPTP). We have investigated the effect of adrenal medullary grafts into the striatum of young mice treated with MPTP. Enhanced recovery of the host nigrostri-atal dopaminergic system was observed in those adrenal medullary grafted mice. However, this recovery was influenced by the survivability ofgrafted chromaffin cells and adrenal chromaffin cells from younger donors survived better than those from older donors. Since adrenal chromaffin cells contain several kinds of neurotrophic factors such as basic fibroblast growth factor and ganglio-sides, survivability of those grafted chromaffin cells may play an important role concerning reco-very of the host intrinsic dopaminergic fibers.

Adrenal medullary grafts to the patients with Parkinson's disease are currently under way in a large number of hospitals and we suggest more consideration be given to methods which lead to enhance the grafted chromaffin cell survival, since those survivability might be closely related to the functional recovery of these patients.
