Effects of acetoxycycloheximide and anisomycin on approach and escape responses to hypothalamic stimulation

The effects of acetoxycycloheximide (AXM) (7 mg/kg) and anisomycin (ANI) (25 and 150 mg/kg) on approach and escape responses induced by hypothalamic stimulation were studied in a situation in which male Swiss mice could initiate a continuous brain stimulation train by pressing a lever at one end of a box (ON-lever) and terminate this stimulation train by pressing a lever at the other end of the box (OFF-lever). AXM and ANI induced a large decrease in ON-OFF responses regardless of the level of stimulation presented (a low level just above the stimulation threshold and a high level which was twice the low level). Correspondingly, a significant increase was observed in the mean time during which animals remained unstimulated (NST) whereas mean time during which animals remained stimulated (ST) increased only slightly. The relative NST increase after treatment was always greater than the relative ST increase either at sites where before treatment NST was greater than ST or at sites where NST was shorter than ST. However, the animals in this latter electrode placement group (ST greater than NST) continued to shuttle and to make lever-pressing responses on the ON-lever, whereas the animals in the other placement group (ST less than NST) did not. These results are discussed in terms of possible interactions between disruptions of reinforcing systems induced by protein inhibitors and their effects on memory.     

Drug preference in normal volunteers: Effects of age and time of day

These experiments assessed the influence of two variables, age of subjects and time of drug administration, on the reinforcing properties of amphetamine and of diazepam in normal volunteers. Three groups of subjects were tested: i) a group of 40–55-year-old subjects (AGE group; N=11) who were tested in the morning, ii) a group of 21–35-year-old subjects (CTL group; N=12) who were also tested in the morning, and iii) a group of 21–35-year-olds who were tested in the late afternoon (AFT group; N=13). All subjects participated in three separate experiments comparing one drug (5 mg d,l-amphetamine, 5 mg diazepam or 10 mg diazepam) to placebo. Each experiment consisted of nine sessions: On the first four sessions subjects sampled two color-coded capsules on alternate sessions and on the following five sessions they chose and ingested the capsule they preferred. Subjective effects of the drugs were monitored using the Profile of Mood States (POMS) and a shortened version of the Addiction Research Center Inventory (ARCI). Subjects in all three groups chose 5 mg diazepam as often as placebo but preferred placebo to 10 mg diazepam. In contrast, they chose amphetamine either as often as or more often than placebo. The subjective effects of diazepam (i.e. sedation) were similar across all three groups, but after amphetamine the AGE group showed greater stimulant effects. In addition, the AFT group showed fewer positive mood effects after amphetamine than the CTL group. The AFT and AGE groups also differed from the CTL group on several measures of mood, independently of drug administration. Despite the modest group differences in subjective effects, it was concluded that neither time of day nor age of subjects substantially affected the reinforcing properties of either drug.
