title: Increase of enkephalin and decrease of substance P immunoreactivity in the dorsal and ventral striatum of the rat after midbrain 6-hydroxydopamine lesions.
abstract: Unilateral 6-hydroxydopamine lesions of the mesostriatal dopaminergic system in the rat resulted in a decrease of substance P-immunoreactivity in the ventral striatum, and in a heterogeneously distributed increase of enkephalin-immunoreactivity in the dorsal and ventral striatum and the globus pallidus. The respective decrease and increase are caused by a lower or higher staining intensity of the peptidergic fibers, whereas no changes were found in the cell bodies.
