The effects of footshock stress on regional brain dopamine metabolism and pituitary [beta]-endorphin release in rats previously sensitized to amphetamine
(Elsevier, 1987-07)
The repeated intermittent administration of amphetamine (AMP) produces an enduring enhancement in the response of dopamine (DA) systems in the brain to a subsequent "challenge" with amphetamine. However, former amphetamine ...
Hormonal effects on extra- and intraneural mechanism: an integrative approach
(Elsevier, 1993-12-01)
Multiple HPA profiles in endogenous depression: Effect of age and sex on cortisol and beta-endorphin
(Elsevier, 1993-01-15)
We have previously shown that a number of depressed patients demonstrated a failure to suppress corticotrophic secretion, as measured by [beta]-Endorphin/[beta]-Lipotropin ([beta]-End/[beta]-LPH levels), following dexamethasone ...
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 ...
Social defeat alters the acquisition of cocaine self-administration in rats: role of individual differences in cocaine-taking behavior
(Springer-Verlag, 2001-12)
Rationale : It is known that social defeat can modulate cocaine self-administration. However, it is unclear whether this psychosocial stressor affects drug-taking behavior to the same extent across all individual animals, ...
Effects of contextual or olfactory cues previously paired with morphine withdrawal on behavior and pain sensitivity in the rat
(Springer-Verlag, 2001-08)
Rationale: Pavlovian conditioning processes have been accorded an important role in maintaining persistent opiate administration. At least one locus for this contribution is during opiate withdrawal. These experiments ...
