The role of serotonergic receptors in the effects ofmu opioids in squirrel monkeys responding under a titration procedure
Autor: K R Powell, Linda A. Dykstra
Publikováno v: Psychopharmacology. 126:42-49
This experiment was conducted to determine whether drugs acting on brain serotonin modulate the effects of the mu opioid, morphine, as measured by the squirrel monkey shock titration procedure and, if so, whether serotonergic modulation is mediated v

Antinociceptive effects of the kappa opioid, U50,488: lack of modulation by 5-HT2 antagonists
Autor: K R Powell, Y. P. Lin, Linda A. Dykstra
Publikováno v: Psychopharmacology. 112:116-120
The kappa opioid, U50,488, was examined alone and in combination with the 5HT2 antagonists, ketanserin, pirenperone and LY 53857. Squirrel monkeys responded under a shock titration procedure in which shock intensity increased every 15 s from 0.01 to

Autoradiographic analysis of the in vivo distribution of 3H-imipramine and 3H-desipramine in brain: Comparison to in vitro binding patterns
Autor: Gary E. Duncan, George R. Breese, Ian A. Paul, K R Powell, Jonathan B. Fassberg, Walter E. Stumpf
Publikováno v: Pharmacology Biochemistry and Behavior. 38:621-631
Using high resolution autoradiographic techniques, the distribution of radioactivity in forebrain and brainstem was assessed after IV injection of 3H-impramine or 3H-desipramine. Results were compared with regional binding of the drugs to brain secti

Opioid agonists/antagonists in morphine-tolerant squirrel monkeys
Autor: Mitchell J. Picker, Linda A. Dykstra, K R Powell
Publikováno v: Pharmacology Biochemistry and Behavior. 36:639-644
The mu-opioid agonist morphine, the opioid antagonist naloxone and the isomers of the mixed action opioids, cyclazocine, n-allylnormetazocine, and pentazocine were examined in squirrel monkeys responding under a fixed-ratio 30 schedule of food presen

The role of serotonin in the effects of opioids in squirrel monkeys responding under a titration procedure: I. Kappa opioids
Autor: K R, Powell, L A, Dykstra
Publikováno v: The Journal of pharmacology and experimental therapeutics. 274(3)
The goal of the present study was to determine whether the serotonin (5-HT) system is involved in the effects of kappa opioids as measured with the squirrel monkey shock titration procedure. With this procedure, electric shock was delivered to the mo
