Antagonism of the discriminative effects of ethylketazocine, cyclazocine, and nalorphine in macaques
(Springer-Verlag, 1984-09)
dl -Ethylketazocine (EKC, 0.01 mg/kg) and saline were established as discriminative stimuli for food-maintained responding in macaque monkeys. Thirty consecutive presses on a right or left lever were reinforced with food, ...
Enkephalinase: Selective inhibitors and partial characterization
(Elsevier, 1980)
There are at least two types of enzymes in brain, endopeptidases and aminopeptidases, which metabolize enkephalins. Evidence is presented to suggest that enkephalinase, an endopeptidase cleaving at the Gly-Phe bond, is ...
A sensitive coupled HPLC/RIA technique for separation of endorphins: Multiple forms of B-endorphin in rat pituitary intermediate vs. anterior lobe
(Elsevier, 1981-08)
A technique is described which couples High Performance Liquid Chromatography (HPLC) to radioimmuno assays (RIA), thus achieving high sensitivity with good specificity. This method allows the separation and detection of ...
The effects of menstrual phase and nicotine abstinence on nicotine intake and on biochemical and subjective measures in women smokers: a A preliminary report
(Elsevier, 1992-11)
Nicotine intake, menstrual and smoking withdrawal symptomatology, and baseline cortisol and MHPG were assessed in nine women smokers under conditions of ad lib smoking and overnight abstinence in three menstrual phases ...
Escape from dexamethasone suppression: Possible role of an impaired inhibitory opioid mechanism
(Elsevier, 1983)
1. 1. Several lines of evidence indicate that the activity of the hypothalamus-pituitary-adrenal (HPA) axis in depression is disinhibited.2. 2. Escape from dexamethasone suppression, although not limited to is more frequent ...
Separation of the convulsions and antidepressant-like effects produced by the delta-opioid agonist SNC80 in rats
(Springer-Verlag, 2005-11)
Delta-opioid agonists produce a number of behavioral effects, including convulsions, antinociception, locomotor stimulation, and antidepressant-like effects. The development of these compounds as treatments for depression ...
Effects of neuropeptide Y, insulin, 2-deoxyglucose, and food deprivation on food-motivated behavior
(Springer-Verlag, 1995-08)
The current study demonstrates the ability of neuropeptide Y (NPY) to increase break points under a progressive ratio 1 (PR1) reinforcement schedule. An initial response resulted in delivery of a food reinforcer (45 mg ...
Levels and distribution of central nervous system amines in normal and morphine-dependent monkeys
(Elsevier, 1972-03)
The distribution of norepinephrine, dopamine and 5-hydroxytryptamine in various areas of the CNS of the normal monkey has been presented.The central levels and distribution of norepinephrine, dopamine and 5-hydroxytryptamine ...
Inhibition of polyphosphoinositide phosphodiesterase by aminoglycoside antibiotics
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1985-08)
The calcium-activated phosphodiesteratic hydrolysis of 32 P-labeled phosphatidylinositol 4,5-bisphosphate and phosphatidylinositol 4-phosphate in prelabeled nerve ending membranes is inhibited by the aminoglycosides neomycin ...
Glucocorticoid-reinforced responding in the rhesus monkey
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1999-11)
Rationale: Glucocorticoids have been reported to have rewarding effects in rats and may lead to drug-seeking behavior in humans under some circumstances. Objectives: The present study investigated whether glucocorticoids ...
