Effects of desipramine on aggressive behavior induced by long-term (6-7 weeks) isolation of mice were examined. Aggressive behavior was measured as duration of biting attack and/or wrestling during a 20-min observation period. Desipramine (5, 10 and 20 mg/kg, IP) and imipramine (10 and 20 mg/kg, IP) dose-dependently increased the duration of aggressive behavior in isolated mice, without inducing aggressive behavior in group-housed animals. Desipramine-induced increase in aggressive behavior was blocked by phentolamine (3 mg/kg, IP) and yohimbine (0.3 mg/kg, IP), but not prazosin (0.5 mg/kg, IP). Clonidine (0.001 mg/kg, IP), an alpha 2 agonist, significantly blocked desipramine-induced enhancement of aggressive behavior in isolated mice without affecting the basal aggression. These data suggest that long-term isolation may induce functional changes in the sensitivity of alpha 2 receptor in the noradrenergic system and that desipramine enhancement of aggressive behavior in isolated mice is modulated by drugs acting onto alpha 2 noradrenergic receptors. 相似文献

Agonistic, locomotor, and stereotyped behavior were measured in male Swiss-Webster mice in their home cage, normally shared with a female, while confronting an intruder mouse. Acute administration of d-amphetamine (2, 4, 8 mg/kg, IP) to resident mice decreased the frequency of attacks toward an untreated intruder, increased the resident's locomotor activity, and induced a small amount of stereotyped behavior. Redetermination of dose-effect functions during chronic treatment (8 or 16 mg/kg/day) indicated that tolerance did not develop to the antiaggressive effect of d-amphetamine. By contrast, the chronically treated mice showed sensitization to amphetamine-induced stereotypies and a diminished sensitivity to the drug's enhancement of locomotor activity. Subsequent tests with cocaine indicated no differences between amphetamine-maintained and saline control animals, providing no evidence for cross-tolerance or cross-sensitization between cocaine's and amphetamine's effects on attack, locomotion, and stereotypies. 相似文献

Male Swiss-Webster mice were administered ethanol immediately before a motor coordination test. Controls and animals treated with 1, 2 or 3 g/kg, IP, of ethanol remained on a suspended meter stick for 240 +/- 0, 232 +/- 8, 93 +/- 2 and 75 +/- 5 sec, respectively. Blood ethanol levels at the end of the test period (4 min) or when the animal fell from the meter stick were 1.02 +/- 0.03, 2.13 +/- 0.09 and 2.24 +/- 0.07 mg/ml for the 1, 2 and 3 g/kg dose of ethanol, respectively. Thirty min prior to ethanol (2 g/kg, IP) animals received L-ascorbic acid in doses of 500 or 1000 mg/kg, IP. Both doses of L-ascorbic acid significantly enhanced the duration of time that the animals spent on the meter stick. When animals were given 1 g/kg, IP, of ethanol their rate of walking (cm/min) on the meter stick was significantly increased over controls. Administration of L-ascorbic acid (1000 mg/kg, IP) 30 min prior to ethanol (1 g/kg) did not change the rate of locomotion. In experiments on ethanol-induced hypnosis (sleep-time), animals received L-ascorbic acid (250, 500, 1000 or 1500 mg/kg, IP) or saline 30 min prior to ethanol (4 g/kg, IP). L-ascorbic acid increased the time of onset of hypnosis significantly at doses of 1000 and 1500 mg/kg. With these doses of L-ascorbic acid sleep duration and blood ethanol content were not altered. L-ascorbic acid, however, increased ethanol-induced hypnosis at a dose of 500 mg/kg.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Investigation of a possible sensitization development to a challenge dose of ethanol after 2 weeks following the single injection in mice 总被引:1,自引:0,他引:1
In the present study, a possible sensitization development to a single injection of ethanol in mice was investigated. Subjects were adult male Swiss-Webster mice. Ethanol (0.5-4 g/kg) or saline (control) was intraperitoneally injected to mice. Horizontal, vertical and ambulatory locomotor activities were recorded for 30 min immediately following the ethanol or saline injections. After 2 weeks, each group of mice was randomly assigned to two groups. A single challenge dose of ethanol (1 g/kg) was administered to the first group, and saline was injected to the second group. Then, the locomotor activities were recorded for 30 min. In the first experiment, ethanol significantly increased the horizontal and ambulatory activities of the mice at the doses of 0.5 and 1 g/kg, but not at 2 g/kg, while they were decreased at the dose of 4 g/kg. Ethanol (0.5 g/kg) also significantly increased the vertical activity. After 2 weeks, the challenge injection of ethanol (1 g/kg) produced some significant increases in the horizontal and ambulatory activities of the group pretreated with ethanol (2 g/kg). It did not cause any significant change on the locomotor activities of the other three groups treated with lower (stimulant) or higher (depressant) doses of ethanol. In addition, there was no significant difference between locomotor activities of the groups challenged with saline. However, a two-way ANOVA of the data on the challenge injections did not indicate any sensitization development to the effects of ethanol on locomotor activities of the mice. Our results suggest that a locomotor sensitization did not develop to a single injection of ethanol after 2 weeks following the first injection in mice. 相似文献

One of the critical mechanisms by which alcohol heightens aggression involves forebrain serotonin (5-HT) systems, possibly
via actions on 5-HT1A receptors. The present experiments tested the hypothesis that activating 5-HT1A receptors by selective agonists will block the aggression-heightening effects of ethanol. Initially, the selective antagonist
WAY 100635 was used to assess whether or not the changes in aggressive behavior after treatment with 8-OH-DPAT and flesinoxan
result from action at the 5-HT1A receptors. Resident male CFW mice engaged in aggressive behavior (i.e. attack bites, sideways threats, tail rattle) during
5-min confrontations with a group-housed intruder male. Quantitative analysis of the behavioral repertoire revealed systematic
reductions in all salient elements of aggressive behavior after treatment with 8-OH-DPAT (0.1–0.3 mg/kg, IP) or flesinoxan
(0.1–1.0 mg/kg, IP). The 5-HT1A agonists also reduced motor activities such as walking, rearing and grooming, although to a lesser degree. Pretreatment with
the antagonist WAY 100635 (0.1 mg/kg, IP) shifted the agonist dose-effect curves for behavioral effects to the right. In a
further experiment, oral ethanol (1.0 g/kg, PO) increased the frequency of attacks in excess of 2 SD from their mean vehicle
level of attacks in 19 out of 76 resident mice. Low doses of 8-OH-DPAT (0.03–0.3 mg/kg) and flesinoxan (0.1, 0.3, 0.6 mg/kg),
given before the ethanol treatment, attenuated the alcohol-heightened aggression in a dose-dependent fashion. By contrast,
these low 5-HT1A agonist doses affected motor activity in ethanol-treated resident mice to a lesser degree, suggesting behavioral specificity
of these anti-aggressive effects. The current results support the hypothesized significant role of 5-HT1A receptors in the aggression-heightening effects of alcohol. If these effects are in fact due to action at somatodendritic
5-HT1A autoreceptors, then the anti-aggressive effects would be associated with decreased 5-HT neurotransmission.

The morphine withdrawal syndrome is composed of profound short- and long-term changes in autonomic, somato-motor and affective functions. In mice, morphine withdrawal produces heightened aggressive behavior and alterations in motor behavior; however, it is unclear whether these changes in behavior occur in unison and are dependent on a common mechanism or occur independently. In order to characterize the morphine withdrawal syndrome in mice, male Swiss-Webster mice were housed with female partners for 3–4 weeks before being implanted subcutaneously with morphine or placebo pellets. The pellets were removed 72 h after implantation and behavioral measurements were conducted 5, 48 and 96 h after pellet removal. During these tests, mice receivedd-amphetamine (0.3–10 mg/kg) or saline after which they were assessed for changes in motor behavior and for changes in aggressive behavior while confronting a group-housed male intruder. In morphine-withdrawn mice, frequency of attack behavior was increased by approximately 30% and this effect persisted for at least 4 days. In contrast, explosive jumping was increased and walking and rearing were greatly decreased at the onset of the withdrawal period but declined within the first 24 h and returned to control levels within 48 h of pellet removal.d-Amphetamine maintained the elevated level of aggressive behavior and sharply increased locomotion in morphine-withdrawn mice; in placebo-pelleted mice,d-amphetamine dose-dependently decreased aggressive behaviors while increasing locomotion. The differential time course and the differential modification byd-amphetamine suggest that heightened aggressive behavior is a long-lasting consequence of morphine-withdrawal based on separate mechanisms than the short-lived alterations in motor activity. 相似文献

In this study male Swiss-Webster mice were used to examine the effects of cysteine (ICV), a precursor in the biosynthesis of taurine, on ethanol-induced loss of the righting reflex. The interaction of ethanol with gamma-aminobutyric acid (GABA) and isethionic acid, a metabolite of taurine, was also investigated on ethanol-induced central nervous system depression as measured by loss of the righting reflex experiments. Immediately after the animals regained the righting reflex following ethanol injection (IP) mice received an ICV injection of saline, cysteine (1, 15 or 25 mumol/kg), GABA (1, 15 or 25 mumol/kg) or isethionic acid (25 or 50 mumol/kg). Upon ICV administration of cysteine or GABA the mice again lost the righting reflex. This effect occurred immediately and in a dose-dependent manner. The compound, isethionic acid, failed to cause a second loss of the righting reflex following ethanol administration (IP). In the absence of ethanol cysteine or GABA (25 mumol/kg, ICV) did not produce a substantial loss of the righting reflex in mice. In another experiment mice were pretreated (IP) with L-2-oxothiazolide-4-carboxylate (OTC) 2 hr prior to ethanol administration (IP). OTC is a compound which can be converted to cysteine in the body. In the presence of ethanol OTC (15 mmol/kg) caused an enhancement of ethanol-induced central nervous system depression under certain conditions.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

The effects of ethanol (0.4, 0.8, 1.6, and 2.4 g/kg p.o.) on behavior of aggressive, timid, and sociable male mice treated with the drug on paired interactions with non-aggressive males given water were investigated. Under control interactions, aggressive mice attacked their partners, timid mice showed defensive-escape activities though their partners were completely non-aggressive, and sociable mice intensively investigated their partners. A low dose of ethanol (0.4 g/kg) increased while higher doses (0.8 to 2.4 g/kg) reduced aggressive activities in aggressive mice. Ethanol (0.8 g/kg) also evoked aggressive behavior in non-aggressive timid mice but no dose of ethanol stimulated aggression in non-aggressive sociable mice. Ethanol altered timid defensive-escape activities only in the highest dose of 2.4 g/kg: this dose increased defences and escapes in aggressive males while it reduced defensive upright postures in timid mice. However, 2.4 g/kg of ethanol reduced also another upright movement (exploratory rearing) in timid mice. Sociable activities were not increased by any dose of ethanol tested. By contrast, 0.4 g/kg of ethanol reduced sniffing and following partners in sociable mice. Thus, ethanol exhibited relatively strong aggression-stimulating effects in aversively disposed subjects while the drug was not able to supress timid defensive escape behavior and to stimulate active non-aggressive contacts between strange male mice. 相似文献

Monoamine and metabolite levels in CNS regions of the P line of alcohol-preferring rats after acute and chronic ethanol treatment 总被引:1,自引:0,他引:1
Levels of norepinephrine (NE), dopamine (DA), 3,4-dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA), serotonin (5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) were determined in 8 brain regions of the P line of alcohol-preferring rats following: (a) an IP injection of 2.5 g ethanol/kg body wt; (b) 8 and 15 weeks of chronic free-choice drinking of 10% ethanol; (c) 15 weeks of chronic free-choice drinking of 10% ethanol and 24 hours of withdrawal; and (d) 7 weeks of forced administration of 5% ethanol in liquid diet. One hour after IP injection of 2.5 g ethanol/kg body wt, the levels of DOPAC and HVA increased 209-45% in the cerebral cortex (CTX) and striatum (STR). A 209% lower content of NE in the CTX of the ethanol group was the only other statistically significant difference observed. Chronic free-choice drinking of 10% ethanol for 8 weeks (6.5 +/- 0.4 g ethanol/kg/day) or 15 weeks (7.8 +/- 0.2 g ethanol/kg/day) and the chronic forced administration of ethanol in liquid diets (up to 13.2 +/- 0.2 g ethanol/kg/day) did not produce any consistent pattern of alterations in the levels of the monoamines or their metabolites in the 8 CNS regions. After 15 weeks of chronic free-choice drinking of 10% ethanol, withdrawal from alcohol also did not produce alterations in the content of the monoamines or their metabolites. These data indicate that acute administration of hypnotic doses of ethanol increases the metabolism of specific dopaminergic neurons in the CNS of the P rat, but monoamine levels and metabolism are not altered after chronic (7-15 weeks) alcohol consumption. 相似文献

Male Swiss-Webster mice were used to examine the effect of NMDA on the ethanol-induced loss of the righting reflex (LORR). The LORR was used as a measure of CNS depression. Immediately after animals regained the righting reflex following ethanol injection (4.0 g/kg, IP) mice received an ICV injection of saline or NMDA (10, 50, 100, or 500 nmol/kg) in a volume of 5 microliters. Upon ICV injection of NMDA, mice again lost the righting reflex and this effect of NMDA in the presence of ethanol occurred rapidly and in a dose-dependent manner. In another experiment DL-2-amino-5-phosphonovaleric acid (APV), a competitive antagonist of NMDA, was given ICV with NMDA (50 nmol/kg) in the presence of ethanol. APV (10 and 100 nmol/kg, ICV) significantly attenuated the response of NMDA to enhance the depressant action of ethanol. When bicuculline methiodide, an antagonist of GABA, was given ICV with NMDA (50 nmol/kg), bicuculline methiodide reduced the effect of NMDA to produce a second loss of the righting reflex (return to the LORR) in the presence of ethanol. When NMDA (100 nmol/kg, ICV) was injected in the absence of ethanol into mice, NMDA by itself did not produce a loss of the righting reflex. In this investigation, the results suggest that NMDA can augment ethanol-induced depression possibly through an interaction between glutamatergic and GABAergeric systems in the CNS. 相似文献

Beginning at 45 days of age, male long-sleep (LS) and short-sleep (SS) mice were placed into individual cages for 21-22 days. Control animals were group-housed for the same amount of time. At 65-66 days of age, animals were given anesthetic doses of ethanol, IP. Measures taken were sleep time, body temperature at 30 and 60 minutes postinjection and blood ethanol content (BEC) at regain of righting response. Compared to the same measures in group-housed animals, sleep times and hypothermia were attenuated in isolate-housed LS and SS mice. Isolate housing resulted in a 15% increase, compared to levels observed in group-housed animals, in BEC at regain of righting in LS; there was no significant difference in BEC in SS mice. The results indicated an isolation-related decrease in sensitivity to the anesthetic effects of ethanol in LS; the effect of isolation in SS may be an increased clearance rate of ethanol. 相似文献

In male Swiss-Webster mice sleep time (hypnosis) was used as an index of ethanol-induced central nervous system depression. Ethanol (4 g/kg, IP) was administered to animals and the onset to sleep time (loss of the righting reflex) and the duration of sleep time were recorded. At the end of the ethanol-induced sleep time, taurine (7.5, 15 or 25 mumol/kg, ICV) was injected. Immediately after the ICV injection of taurine the mice again lost the righting reflex. This effect of taurine occurred in a dose-dependent fashion. In the absence of ethanol, taurine (25 mumol/kg, ICV) did not produce a significant sleep time. In another experiment when TAG, 6-amino-methyl-3-4H-1,3,4-benzothiadiazine-1,1-dioxide HCl, (a taurine antagonist) was given to mice, TAG (0.9 mumol/kg, ICV) significantly reduced the effect of taurine (7.5, 15 and 25 mumol/kg, ICV) to reinstate a sleep time in the presence of ethanol. TAG, however, did not alter ethanol-induced sleep time. These results indicate that taurine (ICV) can enhance the central depressant action of ethanol and that this effect of taurine can be attenuated by TAG. The antagonism of taurine by TAG appears to be noncompetitive in nature. 相似文献

The effect of lithium and rubidium on curiosity rearing, and locomotor activity in isolated and group-housed male mice (DBA/2 Han) was investigated. LiCl and RbCl were given with the drinking water (30 mol/l) during 3 weeks. The behaviour of the animals was tested before and after the chronical application of either lithium or rubidium. The results show that lithium was able to enhance the decreased curiosity of the isolated mice which now was no longer different from that of normal group-housed animals. The locomotor activity of the isolated animals was also increased by LiCl, while rearing was not altered. Rubidium even more decreased the already diminished curiosity of the fighting mice but had no influence on rearing and locomotor activity. Three weeks after cessation of treatment the behaviour of the isolated mice returned to predrug levels. Neither lithium nor rubidium had any influence of the behaviour of animals kept in groups. 相似文献

The effects of N(G)-nitro- l-arginine methyl ester (L-NAME), a nitric oxide synthase inhibitor, SKF 38393, bromocriptine (BRM), quinpirole (QPR) and 7-hydroxy-2-dipropylaminotetralin (7-OH-DPAT), dopamine receptor agonists, and combinations of the dopamine agonists and L-NAME on ethanol-induced locomotor activity in adult male Swiss-Webster mice were investigated. The mice were given ethanol (0.5-2 g/kg), L-NAME (15-60 mg/kg), SKF 38393 (5-20 mg/kg), BRM (2.5 and 5 mg/kg), QPR (0.25 and 0.5 mg/kg), 7-OH-DPAT (0.5 and 1.0 mg/kg), a combination of l-arginine (1 g/kg) and L-NAME (60 mg/kg), combinations of SKF 38393, BRM, QPR or 7-OH-DPAT with L-NAME (60 mg/kg) or ethanol (0.5 g/kg) and saline or vehicle by i.p. injection. Triple combinations (dopaminergic agonist, 60 mg/kg L-NAME and 0.5 g/kg ethanol) were also given. Locomotor activity was measured for 30 min immediately following ethanol injections. Ethanol (0.5 g/kg) significantly increased locomotor activity. L-NAME, BRM, QPR and 7-OH-DPAT blocked the ethanol (0.5 g/kg)-induced locomotor hyperactivity dose dependently and at doses that did not affect locomotor activity in naive mice when administered alone. The inhibitory effects of L-NAME (60 mg/kg) were not prevented by pretreatment with l-arginine. BRM and QPR, but not 7-OH-DPAT, significantly and dose-dependently potentiated the inhibitory effect of L-NAME. Our results suggest that L-NAME inhibits ethanol-induced locomotor hyperactivity in mice by a mechanism not involving NO. The inhibitory effect of L-NAME may be related to the activation of presynaptic dopamine D(2) receptors rather than dopamine D(3) receptors. 相似文献

The effects of acutely administered ethanol (0, 0.5, 1.0 and 2.0 g/kg, IP) were studied in a tube-restraint/target biting model of aggressive responding using naive group-and individually-housed male Swiss mice. Behavioural measures were the latency to the first bite and the biting frequency. In saline-injected control animals, the levels of responding were significantly higher in group-housed than isolated mice. Animals given alcohol exhibited a dose-dependent suppression of biting frequency, and an increase in biting latency. Mice experienced in the tube-testing situation showed reduced baseline levels of biting, but alcohol produced similar effects to those in naive mice. There was no evidence of a biphasic action of alcohol. 相似文献

The effects of ethanol in Porsolt's swim test on mice preexposed to fight- or swim-stressors were investigated. The control mice did not change their behavior in the swim test after an acute injection of 0.4 or 0.8 g/kg ethanol; 1.2 g/kg ethanol increased their immobility in one but not in another experiment. The mice exposed to continuous fight-attacks in their home cage by one dominant mouse shortened immobility after 0.8 g/kg ethanol as well as tended to shorten it after 0.4 g/kg ethanol. The mice that were forced to swim in the water twice before the actual swim test responded to 0.4 g/kg ethanol by shortening immobility; 0.8 g/kg tended to have the same effect; 1.2 g/kg ethanol just failed to lengthen immobility of the fight-stressed mice and had no effect on the swim-stressed mice. Because antidepressant drugs decrease and stressors increase immobility in the swim test, the test may serve as a putative animal model of depression. The present findings showed that low doses of ethanol reverse lengthened immobility of mice preexposed to a stressor. This suggests that ethanol either has antidepressant-like properties, or it improves animal's ability to cope with a stressful situation, or both. 相似文献

The climbing response to apomorphine (AP, 0.075–3.0 mg/kg) and the motor activity response to amphetamine (AMP, 0,3–5.0 mg/kg) were determined in grouped or socially isolated mice. After 4 weeks of differential housing commencing at 5 weeks of age, the individually housed mice showed an increased response only to low doses of these drugs. The responses of the group-housed mice at 5 or 9 weeks of age were identical, ruling out an aging component to the differential responsiveness. Also, the response of separate groups of naive mice to acute treatments of saline, AP (0.15 and 3.0 mg/kg), and AMP (0.3 and 5.0 mg/kg) was examined at 1, 2, 3, and 4 weeks of differential housing. With respect to age-matched group-housed mice, a significantly greater climbing response to AP (0.15 mg/kg) and a significantly greater locomotor activity response to AMP (0.3 mg/kg) were seen after 1 and 3 weeks of individual housing. There were no significant differences in the behavioral responses to the higher doses of AP and AMP. 相似文献

Ethopharmacological procedures and a two-compartment black and white test box were used to examine behavioural effects produced by the benzodiazepine receptor inverse agonist, methyl-6,7- dimethoxy-4-ethyl-β-carboline-3-carboxylate (DMCM), when given by intraperitoneal injection (0.4 and 1.0 mg/kg) to pair-housed adult CD1 male mice. Control mice received injections of the solvent. Behaviour in the light-dark box was examined at 30 min after the injection and behaviour during encounters with an untreated group-housed male, in a neutral cage, was then assessed by ethological procedures. In dominant mice, aggressive behaviour was significantly reduced and the ratio of flight, relative to aggression received, was significantly increased by DMCM at 0.4 mg/kg. At 1 mg/kg but not 0.4 mg/kg, DMCM decreased time spent by dominant mice in the light compartment of the test box. In both dominant and subordinate mice, flight was increased by DMCM at 1 mg/kg to a level close to statistical significance. Treatment with DMCM had no other detectable effect on the behaviour of subordinate animals. It is suggested that anxiogenic activity of this compound might induce a shift of agonistic behaviour from aggression to “fear-induced flight”. 相似文献

The stimulatory effects of low alcohol doses are of great interest because of their role in human drinking and their possible relation to reinforcement from alcohol. The preferred animal model for studying them is the mouse. The effects of various doses of ethanol on locomotor activity were now studied in both group-housed mice and in mice socially isolated for 36-44 weeks. The housing situation was found to have a strong influence: a large stimulatory effect was observed in isolated mice but little effect was seen in group-housed animals. The results suggest that socially isolated mice are more sensitive to the stimulatory effect of ethanol on locomotor activity. 相似文献

The effects of cyclobenzaprine, a tricyclic compound, on the central depressant action of ethanol and on hepatic ethanol metabolizing enzymes were studied in rodents. Administration of cyclobenzaprine, 5 mg/kg, IP, 30 min prior to a narcotic dose of ethanol solution, 5 g/kg, IP, enhanced ethanol-produced narcosis in mice. This effect was greater in male than in female mice. Cyclobenzaprine inhibited endogenous rat liver alcohol dehydrogenase in vitro in the concentration range between 10−5M and 10−6M. Cyclobenzaprine exerted little effect on hepatic aldehyde dehydrogenase in vitro. The results suggest that cyclobenzaprine possesses depressant properties and inhibition of liver alcohol dehydrogenase may underlie the observed behavioral response studied. It is concluded that alteration of endogenous liver alcohol dehydrogenase by certain tricyclic antidepressant drugs may be involved in the mechanism(s) of their toxic interaction with ethanol. 相似文献
