To determine whether opiate consumption is affected by laboratory housing, individually caged and colony rats were given a choice between water and progressively more palatable morphine-sucrose solutions. The isolated rats drank significantly more of the opiate solution, and females drank significantly more than males. In the experimental phase during which morphine-sucrose solution consumption was greatest, the isolated females drank five times as much, and the isolated males sixteen times as… Expand

Figures, Tables, and Topics from this paper

Isolation housing decreases the effectiveness of morphine in the conditioned taste aversion paradigm
TLDR
The data strengthen the already existing evidence for the influence of the early housing environment on drug sensitivity and provide additional support for the conclusion that variability in response to a number of drugs of abuse can be reduced by environmental means. Expand
Isolation rearing enhances the locomotor response to cocaine and a novel environment, but impairs the intravenous self-administration of cocaine
TLDR
Male Lister hooded rats were raised from weaning either alone (isolation reared) or in groups of five (socially reared controls) and their interactions with the mesoaccumbens dopamine projection were discussed with reference to dysfunctional cortico-limbic-striatal systems. Expand
Wheel-running attenuates intravenous cocaine self-administration in rats Sex differences
TLDR
It is indicated that wheel-running activity had a greater suppressant effect on cocaine self-administration in females than in males, and in females, wheel- running and cocaineSelf-Administration are substitutable as reinforcers. Expand
Effects of early environmental experience on self-administration of amphetamine and barbital
TLDR
Individual differences in rates of initiation, choice of abusing agent, and maintenance of drug self-administration may be partially determined by pre-existing differences in central nervous system functioning due to early experiences. Expand
The effects of social contact on cocaine intake under extended-access conditions in male rats.
TLDR
The data indicate that the behavior of a social partner influences cocaine self-administration under conditions that model problematic patterns of drug use. Expand
Does Exercise Deprivation Increase the Tendency Towards Morphine Dependence in Rats?
TLDR
The study showed that discontinuation of exercise does not increase the tendency of morphine dependence in rats and showed no significant difference between the two groups of animals. Expand
Gender differences in the intravenous self-administration of mu opiate agonists
TLDR
Data collectively show that mu opiate agonists may serve as reinforcing agents in females over a broader dose range than males and that they also self-administer considerably more opiates on a milligram per kilogram basis. Expand
Female and male rats readily consume and prefer oxycodone to water in a chronic, continuous access, two-bottle oral voluntary paradigm
TLDR
Female and male rats voluntarily ingest and choose oxycodone over water and show both dependence and motivation to take oxy codone during a chronic oral voluntary, two-bottle choice, continuous access paradigm and both sexes displayed many features of human oxyCodone abuse. Expand
Female rats consume and prefer oxycodone more than males in a chronic two-bottle oral voluntary choice paradigm
TLDR
Female rats consumed and preferred oxycodone more than males in this chronic two-bottle oral choice paradigm, providing an additional paradigm for understanding mechanisms that mediate long-term voluntary drug use and for exploring potential treatment options. Expand
Sex differences in the acquisition and maintenance of cocaine and nicotine self-administration in rats
TLDR
Differences in acquisition amongst sexes can reveal factors that are integral to initiation of drug use, an often overlooked phase of drug addiction. Expand

The effect of housing and gender on morphine self-administration in rats
To determine the effect of housing conditions on morphine self-administration, rats isolated in standard laboratory cages and rats living socially in a large open box (8.8 m2) were given morphine inExpand
Cocaine and morphine self-administration: Effects of differential rearing
  • S. Hill, B. Powell
  • Medicine, Psychology
  • Pharmacology Biochemistry and Behavior
  • 1976
TLDR
Validating previous reports of differential rearing effects on body weight, the enriched animals in the present study weighed less than their litter mates reared in impoverished conditions. Expand
Dependence to morphine in differentially housed rats
TLDR
When abstinence was precipitated with naloxone, isolated rats demonstrated less jumping and less diarrhea than grouped rats, and differences were seen both in isolates developing muricidal behavior and those not developing this behavior. Expand
Induced preference for morphine in rats
TLDR
It was concluded that morphine dependency, indicated by the self-selection of morphine, was induced by forcing consumption of weak solutions of morphine for 12 weeks. Expand
Opiate dependence produced by ad libitum drinking of morphine in water, saline, and sucrose vehicles
TLDR
Concomitant morphine withdrawal signs (body weight loss, anorexia, adipsia, rhinorrhea, diarrhea, and irritability) were observed, thus indicating the animals were drug dependent. Expand
Preferences for morphine in rats: Validation of an experimental model of dependence
TLDR
It appeared that the post-ingestional effects of morphine provided primary reinforcement for the rats; they were able to regulate their daily intake of the drug after being injected with varying doses of it and they lost weight abruptly during enforced abstinence. Expand
Addiction liability of Tryon rats: Independent transmission of morphine and alcohol consumption
  • S. Hill
  • Medicine, Biology
  • Pharmacology Biochemistry and Behavior
  • 1978
TLDR
Two inbred strains of Tryon rats were tested for consumption of morphine and alcohol and factors affecting consumption of drug solutions including sex and activity level were assessed using analysis of covariance. Expand
Morphine analgesia in grouped and isolated rats
TLDR
The results indicate that chronically isolated rats, whether developing muricidal behavior or not, show no alteration in either pain thresholds or in their response to morphine-induced analgesia. Expand
Morphine action in grouped and isolated rats and mice
TLDR
The present study determines the analgesic effects of morphine in grouped and isolated rats and mice and finds that isolated mice, particularly low aggressors, gave enhanced responses to morphine. Expand
Voluntary morphine ingestion, morphine dependence, and recovery from withdrawal signs
TLDR
The present finding is the first report to show that rats ingest high quantities of sucrose-morphine without premedication or forced hydration procedures. Expand
