Increase in delta, but not mu, receptors in MSG-treated rats
(Elsevier, 1982-09)
Neonatal treatment of rats with Monosodium Glutamate (MSG) has been demonstrated to destroy cell bodies of neurons in the arcuate nucleus including the brain beta-endorphin (B-END) system. The effects on opiate receptors ...
Peptide F (pro-enkephalin fragment) : Radioimmunoassay, and stress-induced changes in adrenal
(Elsevier, 2006-04-07)
Utilizing a nine amino-acid (Asp-Glu-Leu-Tyr-Pro-Leu-Glu-Val-Glu) non-enkephalin containing fragment of Peptide F from the pro-enkephalin molecule, a radioimmunoassay was developed. Extraction of bovine, rat, and guinea ...
Plasma beta-endorphin-like immunoreactivity, self reported pain perception and anxiety levels in women during pregnancy and labor
(Elsevier, 2006-04-07)
Plasma Beta-endorphin (B-END) immunoreactivity was measured in 19 men, 16 women at midcycle, and ten pregnant women at various points in their pregnancies. There is a significant difference between the levels measured in ...
Anatomical relationship between opioid peptides and receptors in rhesus monkey brain
(Elsevier, 1984-12)
To determine whether opioid peptide-receptor pharmacological associations found in vitro (e.g., enkephalin-[delta], dynorphin-[kappa]) predict anatomical relationships in situ, immunocytochemical and receptor autoradiographic ...
Pulse-chase studies of the POMC/Beta-endorphin system in the pituitary of acutely and chronically stressed rats
(Elsevier, 2006-04-07)
Experiments were carried out to determine whether stress induces biochemical changes in the pro-opiomelanocortin (POMC) system in anterior (AL) and intermediate-posterior lobe (IPL) of rat. In a series of pulse-chase ...
Inhibition of opiate tolerance by non-competitive receptor antagonists
(Elsevier, 1994-01-07)
Our laboratory and others have previously reported that the non-competitive (NMDA) receptor antagonist, MK-801, interferes with the development of tolerance to the analgesic effects of morphine. The present studies were ...
A comparison of D1 receptor binding and mRNA in rat brain using receptor autoradiographic and in situ hybridization techniques
(Elsevier, 1992-02)
D1, a subtype of the dopamine receptors, is widely distributed in the nervous system and has been shown to be positively coupled to adenylate cyclase. Using a combination of in vitro receptor autoradiographic and in situ ...
The preferential release of beta-endorphin from the anterior pituitary lobe by Corticotropin Releasing Factor (CRF)
(Elsevier, 1986)
Although a number of investigators have shown that release of ACTH is accompanied by the release of Beta-endorphin ([beta]-End) and Beta-lipotropin ([beta]-LPH), the proportion of the latter two peptides released with ...
Steady state levels of pro-dynorphin-related end products in the striatum and substantia nigra of the adult rhesus monkey
(Elsevier, 1985)
Analysis of an acid extract of the striatum of the rhesus monkey revealed that the molar ratio of dynorphin A(1-8)-sized material and dynorphin (A(1-17)-sized material is approximately 1:1. In addition, the molar ratios ...
