abstract：:Unilateral 6-hydroxydopamine lesion to rat substantia nigra pars compacta resulted in a modest, but significant, decrease in the specific binding of N-alpha-[methyl-3H]histamine (19 +/- 5% reduction) to synaptosomal membranes from ipsilateral striata. Dopamine synthesis was assessed in striatal slices by determining [...
