Effects of morphine treatment on pro-opiomelanocortin systems in rat brain
(Elsevier, 1990-06-11)
In previous studies to determine whether chronic opiate administration might negatively feedback upon endogenous opioid systems in the CNS, investigators found no changes in steady-state concentrations of opioid peptides ...
In Vitro release of hypothalamic [beta]-endorphin [beta]E by arginine vasopressin, corticotropin-releasing hormone and 5-hydroxytryptamine: Evidence for release of opioid active and inactive [beta]E forms
(Elsevier, 1990-05)
The aims of the present experiments were: 1) to test whether substances which modulate beta-endorphin-immunoreactive [beta]E-ir release from the pituitary gland might act similarly in hypothalamic tissue; and 2) to further ...
Regulation of striatonigral prodynorphin peptides by dopaminergic agents
(Elsevier, 1990-06-04)
The primary purpose of this study was to examine the regulation of prodynorphin peptides by dopaminergic agents in the central nervous system. The indirectly acting catecholamine agonist -amphetamine sulfate (AMPH) and the ...
