title: Enkephalinergic markers in substantia nigra and caudate nucleus from Parkinsonian subjects.
abstract: Marked reductions in opiate receptor binding (-42%), "enkephalinase" activity (-39%), and Met5-enkephalin levels (-72%) accompanied the well-established dopamine depletion in the substantia nigra pars compacta of Parkinsonian subjects. In contrast, enkephalinergic markers were not significantly modified in caudate nucleus.
