The opioid benzodiazepine, tifluadom, and the benzodiazepine tranquilizer, diazepam, were compared for their influence on morphine and scopolamine-induced locomotor stimulation in mice. Diazepam enhanced drug-induced hyperactivity, while tifluadom had no effect or reduced locomotor activity. The results demonstrate that tifluadom, a benzodiazepine compound(More)
m-Chlorophenylpiperazine (CPP) given in doses up to 2 mg/kg did not affect conditioned avoidance responses (CAR) of CD-1 mice pre-trained in a shuttle box. It reversed the inhibitory action of trazodone (10 mg/kg) on CAR, but dose-dependently potentiated the inhibitory effect of pimozide (0.2 and 0.5 mg/kg). Apparently, dopaminergic transmission is(More)
Mice of C57BL/6 (C57), Balb/c (BALB), and CD-1 (CD) strains were injected with 3-chlorophenylpiperazine (CPP), 1-10 mg/kg ip, and their exploratory and basal locomotor activities and acquisition of conditioned avoidance response in a shuttle-box were tested. In C57 mice CPP did not affect either locomotor activity or shuttle-box performance. In BALB mice(More)
Nucleus caudatus--putamen (CP) or nucleus accumbens septi (A) were stimulated electrically for 30 min in free moving rats. Immediately or 30 min after the stimulation we studied the level of 5-HTP and DOPA accumulated in the mesencephalon+pons+medulla oblongata, after inhibition of activity of aromatic amino acids decarboxylase by NSD 1015, and intensity of(More)
Clonidine inhibited the exploratory motor activity of C57BL/6 mice non-habituated to the testing conditions. In CD-1 mice clonidine did not depress exploratory activity but did elevate the basal locomotor activity of animals both non-habituated and habituated to testing conditions. Amphetamine increased the locomotor activity of many C57BL/6 mice and(More)
Spontaneous locomotor activity has been studied in mice treated with chlordiazepoxide, atropine, and scopolamine, given alone or in combination. Chlordiazepoxide alone increased activity for a short time, while the two anticholinergic drugs produced longer lasting stimulatory effects. Locomotor stimulation was stronger when chlordiazepoxide and(More)
Pharmacological properties of alpha-(AFG), beta-(FG) and gamma-(GFM) phenyl-substituted derivatives of GABA and their respective lactams (FP, FL, FM) were studied in rats and mice. All studied compounds diminished spontaneous and pharmacologically potentiated motility, lowered body temperature of mice, and weakened conditioned reflexes in rats. Some of the(More)
