Alcohol exerts numerous pharmacological effects through its interaction with various neurotransmitters and neuromodulators. Among the latter, the endogenous opioids play a key role in the rewarding (addictive) properties of ethanol. Three types of op

It has been shown previously that opioids induce antinociceptive effects at peripheral sites in the presence of inflammatory processes. Besides being elicited by local injection of opioids, such effects can also be obtained by activation of intrinsic

Our previous studies indicate that endogenous opioids (primarily beta-endorphin) released during stressful stimuli can interact with peripheral opioid receptors to inhibit nociception in inflamed tissue of rats. This study sought to localize opioid p

The mesolimbic dopaminergic system has been implicated in mediating the motivational effects of opioids and other drugs of abuse. The site of action of opioids within this system and the role of endogenous opioid peptides in modulating dopamine activ

The influence of prolonged pain upon hypothalamic opioid peptide release in vitro was examined in rats subjected to Freund's adjuvant (FA)-induced unilateral inflammation of the hindlimb. Basal release of enkephalin (ENK) but not beta-endorphin (END)

In the present study we used in vivo microdialysis to examine the influence of beta-endorphin-(1-27) (beta-EP-(1-27) upon beta-endorphin (beta-EP)-induced dopamine (DA) release in the nucleus accumbens of anesthetized rats. Microdialysis probes were

In vivo microdialysis was used to compare the effects of beta-endorphin upon dopamine (DA) release in the nucleus accumbens (NAC) of anesthetized versus freely moving rats, and to examine the role of the mesolimbic DA system in mediating both the mot

In the present study we used in vivo microdialysis to examine the influence of beta-endorphin on dopamine (DA) release in the nucleus accumbens of anesthetized rats and to identify the opioid receptor types mediating its effects. Microdialysis probes

An involvement of the mesolimbic dopamine (DA) system in mediating the motivational effects of opioids has been suggested. Accordingly, the present study employed the technique of in vivo microdialysis to examine the effects of selective mu-, delta-,
