Abstract
THE present study was carried out to determine if iron chloride (FeCl3 ) injections into the substantia nigra of guinea-pigs produced changes in nigro-striatal uric acid levels. Two-weeks following unilateral in jection of FeCl3 (185 nmol Fe3+), ipsilateral uric acid levels were in creased 176% over contralateral levels in the substantia nigra. No eff ect on striatal uric acid levels was observed. Iron chloride injection produced a 74% depletion of dopamine levels in the ipsilateral striat um. Ipsilateral/contralateral ratios were significantly decreased for striatal dopamine and significantly increased for nigral uric acid whe n compared with saline-injected controls. The results of this work ind icate that FeCl3 injections into the substantia nigra of guinea-pigs p roduce a significant, localized increase in tissue uric acid levels tw o weeks after treatment.
