The release of Met-enkephalin immunoreactive material (ME-IR) from rat spinal slices was measured in vitro. This release increased about 4 fold in response to the addition of K+ ions. K+-evoked release of ME-IR was Ca++ dependent. Veratridine, a depolarizing agent, also stimulated the release of ME-IR. Veratridine-induced ME-IR release was completely(More)
Met-enkephalin levels were measured in various spinal cord regions of rats chronically suffering from the inflammation of a single paw following a treatment with Freund's adjuvant. The results indicate that chronic localized pain induces a selective increase of met-enkephalin immunoreactive material (ME-IR) in the dorsal horn of the spinal cord segment(More)
Sarcoidosis is an inflammatory multisystem disorder of unknown cause. Approximately 5-7% of patients manifest symptoms of central nervous system involvement, or neurosarcoidosis. Cranial neuropathy usually entails facial nerve palsy and optic neuritis. Sudden hearing loss has been reported in fewer than 20 cases. Herewith, two new cases of sudden hearing(More)
Immunocytochemical and electrophysiological studies indicate the existence of a functional relationship between Cholecystokinin (CCK) and dopaminergic transmission. In order to gain more information on this relationship, the effect of Caerulein, a CCK stable analogue, on rat spontaneous locomotor activity and on biochemical markers of dopaminergic(More)
