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), ...
Postdexamethasone plasma cortisol and [beta]-endorphin levels in depression: Relationship to severity of illness
(Elsevier, 1987-09)
The hypothalamic-pituitary-adrenal (HPA) axis is dysregulated in many patients with depression, probably at all levels of the axis. To determine if HPA dysregulation is associated with severity of depression, we studied a ...
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) ...
