OBJECTIVES This study aimed to assess the analgesic effect of kilohertz alternating current applied to the severed nerves in amputees afflicted by intractable limb pain. METHODS Ten lower-limb amputees with chronic and severe residual limb pain or phantom limb pain who attained significant pain reduction after local nerve block injection were enrolled. A(More)
Albino Sprague-Dawley rats (1, 8, 12 and 20 days old) were injected intraperitoneally with l-[3H-1]-methadone (5 mg/kg containing 50 muCi/kg), and sacrificed at 15 min, 1 h and 3 h. Whole brain was homogenized in 0.32 M sucrose-Tris buffer and the homogenates were subjected to differential centrifugation to separate nuclei, mitochondria, microsomes, soluble(More)
1. Neuroanatomical distribution of [14C] methylphenidate has been examined in rabbit brain following intracerebroventricular administration. 2. After about a week of implantation of cannula, in lateral ventricle, in albino rabbits, [14C] methylphenidate was injected through the cannula. The distribution of [14C] methylphenidate was examined at 15, 60 and(More)
In view of potential ability of calcium entry blockers to affect Ca2+ fluxes in neurons, the effects of nisoldipine on phencyclidine (PCP) and apomorphine (APO) induced stereotyped behavior have been examined in 3 and 4 week old rats. The rats (3 and 4 weeks old) were pretreated with either 0.2 ml of saline + ethanol mixture (10:1 v/v) or nisoldipine (25(More)
Mescaline (25 mg/kg; 66 muc/kg) was injected (ip) in mice 45 min before chlorpromazine (CPZ, 2.5, 5, 15 mg/kg), thioridazine (10, 30, 45 mg/kg), or chlorpromazine-sulfoxide (CPZ-SO, 15 mg/kg). Excitement, agitation, slight increase in ventilation and occasional head-shaking were seen 30 min after mescaline and continued for 30-45 min thereafter; locomotor(More)
Distribution of orally administered methaqualone-14C (25 mg/kg) in several rat brain areas was examined. Peak concentration attained at 1.5 hr. Among brain areas, highest concentration was measured in pineal gland (8.2 microgram/g). MTQ levels in the cortex, pituitary, hypothalamus and hippocampus ranged from 3 to 3.5 microgram/g, those in the mid-brain,(More)
Mice were injected ip with either saline, l-methadone (2.5, 5, 20 mg/kg), perphenazine (1, 10, 15 mg/kg), or chlorprothixene (1.25, 2.5, 15 mg/kg) 30 min prior to mescaline-14C (25 mg/kg). Mescaline-induced behavioral changes such as agitation, excitement, slight increase in ventilation, and fright to sound stimuli were prevented by all doses of three(More)
Behavioral aspects and metabolic fate of N,N-dimethyltryptamine (DMT) were studied in mice pretreated with beta-diethylaminoethyl-diphenylpropylacetate (SKF 525-A), iproniazid or chlorpromazine (CPZ). DMT at doses of 2.5, 10.0, and 25.0 mg/kg produced several behavioral changes in a dose-related manner: inhibition of spontaneous locomotor movement, enhanced(More)
