title: [Effect of benzatropine on the O-methylation of striatal dopamine].
abstract: After treatment by nialamid, benztropine administered to Rats produced an increase in the level of 3-O-methyldopamine in the corpus striatum. It produced a slight increase in the level of striatal dopamine and no change in the level of norepinephrine. The monoamine oxydase and catechol-O-methyltransferase activities of remaining brain showed no variations by benztropine. The results suggest the possible involvement of striatal dopamine and its extraneuronally catabolism in the antiparkinsonian effect of benztropine.
