Analysis of opioid and non-opioid end products of pro-dynorphin in the substantia nigra of the rat
(Elsevier, 1985-02)
The substantia nigra is among the richest pro-dynorphin terminal field regions in the rat brain. We therefore contrasted processing in this area to the known processing in the posterior pituitary. Fractionation of acid ...
[3H] dynorphin binding to guinea pig and rat brain
(Elsevier, 1983)
[3H] Dynorphin can be shown to bind to the brains of both rat and guinea pigs with approximately 50% specific binding. Characterization of the binding in terms of multiple opiate receptor types supports the kappa selectivity ...
Lateral hypothalamic innervation of the cerebral cortex: Immunoreactive staining for a peptide resembling but immunochemically distinct from pituitary/arcuate [alpha]-melanocyte stimulating hormone
(Elsevier, 1986-01)
The combination of retrograde transport of fluorescent dyes and indirect immunofluorescence has been used to study the putative neurotransmitter specificity of the tuberal lateral hypothalamic projection to the cerebral ...
Anatomical and biochemical studies of the opioid peptides and related substances in the brain
(Elsevier, 1980)
It is now clear that there are at least four opioid peptide-neuronal systems in mammalian brain: the enkephalins, beta-endorphin and dynorphin. The focus of this presentation will be twofold--to focus on the multiple ...
Changes in releasability of ACTH and Beta-endorphin with chronic stress
(Elsevier, 1985-02)
The activation of the hypothalamic pituitary adrenal axis by stress is well-known. Using inescapable intermittent footshock as a stressor in rats, we have previously demonstrated a rise in circulating plasma Beta-endorph ...
A possible interface between autonomic function and pain control: opioid analgesia and the nucleus tractus solitarius
(Elsevier, 1987-10-20)
Opioid peptides appear to be important neurochemical mediators in central nervous system mechanisms of analgesia, cardiovascular control, and many endocrinological responses to stress. The nucleus tractus solitarius (NTS), ...
Chronic electroconvulsive shock treatment elicits up-regulation of CRF and AVP mRNA in select populations of neuroendocrine neurons
(Elsevier, 1989-11-06)
The effects of repeated electroconvulsive seizures (ECS) on expression of mRNAs coding for corticotropin-releasing factor (CRF) and arginine vasopressin (AVP) in neuroendocrine neurons of the hypothalamo-pituitary-adrenocortical ...
The degradation of dynorphin A in brain tissue in vivo and in vitro
(Elsevier, 1987)
The demonstration of analgesia following in vivo administration of dynorphin A (Dyn A) has been difficult. In contrast, a number of electrophysiological and behavioral effects reported with in vivo injection of Dyn A can ...
Further characterization of the extra-arcuate alpha-melanocyte stimulating hormone-like material in hypothalamus: Biochemical and anatomical studies
(Elsevier, 1986-04)
Previous studies had shown the existence of an extra-arcuate cell group in lateral hypothalamus which contains alpha-melanocyte stimulating hormone (a-MSH)-like immunoreactivity, but no other pro-opiomelanocortin (POMC) ...
Acute systemic administration of morphine selectively increases mu opioid receptor binding in the rat brain
(Elsevier, 1984-12)
Opioid receptor binding, including the mu, delta, and kappa receptor subtypes, was compared in morphine-injected and control rats. Brain tissues were homogenized and centrifuged either one or two times prior to receptor ...
