The present experiment examined ethanol self-administration in C57BL/6J (C57) and DBA/2J (DBA) mice using a continuous access operant procedure. Adult male C57 and DBA mice were initially trained to perform a lever press response to obtain access to 10% w/v sucrose solution. Subsequently, the mice were placed in operant chambers on a continuous (23 hr/day)(More)
Dopaminergic systems are thought to play an important role in the motivational effects of ethanol. The present experiments examined the effects of haloperidol (a D2 antagonist) and SCH-23390 (a D1 antagonist) on the acquisition of ethanol-induced conditioned taste aversion. In four separate experiments, adult male Swiss-Webster mice were acclimated to a(More)
Genetic differences in nicotine-induced conditioned taste aversion were examined using inbred mice. Adult male C57BL/6J, DBA/2J, BALB/cJ and C3H/heJ mice were adapted to a 2-h per day water access regimen. Subsequently, mice received nicotine injections (0.5, 1.0 or 2.0 mg/kg) immediately after 1-h access to a NaCl flavored solution. DBA and C3H mice(More)
To evaluate the toxicity, pharmacological and biological properties of ATN-161, a five -amino-acid peptide derived from the synergy region of fibronectin, adult patients with advanced solid tumours were enrolled in eight sequential dose cohorts (0.1-16 mg kg(-1)), receiving ATN-161 administered as a 10-min infusion thrice weekly. Pharmacokinetic sampling of(More)
BACKGROUND Studies in humans and animals suggest that those with a genetic predisposition toward high levels of alcohol consumption have decreased pain thresholds. The present study explores this association in rat lines selectively bred for alcohol preference or nonpreference. METHODS 13 HAD1, 11 LAD1, 16 iP5C, and 16 iNP1 rats were tested in the Ugo(More)
The concentrations in plasma of the biologically active endogenous peptide Tyr-MIF-1 (Tyr-Pro-Leu-Gly-NH2) have not been measured during development or in female rats. By radioimmunoassay, we found that Tyr-MIF-1-like immunoreactivity (Tyr-MIF-1-LI) was first consistently detectable in plasma when the rat was 5 days old, and then gradually increased to(More)
The effects of MIF-1 (Pro-Leu-Gly-NH2) on activity and aggression of male Siamese Fighting Fish ( Betta splendens) were considered. Animals were given intraperitoneal injections of 0.0 or 10.0 mg/kg MIF-1. After a 10-minute delay, they were placed in a 10 gallon aquarium and their activity was monitored for 60 minutes. Although aggressive responses in the(More)
