Abstract
It has been well established that the striatal dopaminergic system is compromised with aging, namely D2 receptor function. Also well documented is the age related decline of the neurohormone, melatonin, in both humans and nonhuman animals. What has not been well studied is the possible interaction between the D2 receptor system and the age related decline in melatonin with its unmistakable pattern of synthesis and release exclusively during the dark phase. We tested the effect of the D2 antagonist, haloperidol (1.0 mg/kg ip), in adolescent (2 mo old) and adult rats (10 mo old) in the light (ZT3) and dark phases (ZT 15) in rats kept in a 12 L/12D cycle and the effect of exogenous melatonin (15 mg/kg ip/day x 4 days for a total of 60 mg/kg) on D2 antagonism. Using the bar test, measuring the extrapyramidal side-effect of hypokinesia, we report haloperidol to work differentially depending on both age and phase. Adult rats experienced the effect of the D2 antagonist in both the light and dark phases, while younger rats did not show hypokinetic affects in the dark. By manipulated lighting, we were able to restore the effect of haloperidol in younger rats in the dark phase. We also found ameliorating effects of melatonin lessening time on the bar after treatment with haloperidol, however, this effect was only found in older rats. These data demonstrate the importance of the light/dark cycle and age in the susceptibility of extrapyramidal effects with use of drugs that target D2 receptor function.

Abstract
The effects of the antidepressant drugs trazodone and imipramine on the circadian rhythm were studied by means of the sleep propensity test (SPT; sleep latency was examined by 35-minute EEG records at 09:00, 11:00, 13:00, 15:00, 17:00). The subjects were 11 healthy male volunteers (mean age, 23.6 years old). The drugs were administered 4 times a day with single blind trials using an inactive placebo as a control. The dosages of the drugs were trazodone 50-100 mg/day and imipramine 20-40 mg/day. We discussed the circadian rhythm referring to previous polysomnograhy (PSG) studies using the same drugs and dosages with most of the same subjects. As a result, the mean sleep latency of SPT was the shortest at 09:00 (p<0.1) with a placebo, at 11:00 (p<0.05) with trazodone and at 13: 00 (not significantly) with imipramine administration. These results suggested that neither drug affected sleepiness. They affected the circadian rhythm during the daytime (=the day rhythm). They delayed the day rhythm. Delay of the day rhythm was due to trazodone and have been caused by not only trazodon administration itself, but also by the increase of slow-wave sleep obtained in the previous night's PSG study. And the day-rhythm delay was due to imipramine and might have been caused by not only imipramine administration itself, but also by the decrease in the percentage of slow-wave sleep and REM sleep, and an increase in REM latency obtained in the previous night's PSG study. Therefore, we concluded that neither drug affected the tendency toward sleepiness, but did affect the day rhythm in healthy subjects.

Abstract
The efficacy of psychotropic drugs varies depending on the time of administration. This phenomenon is observed with antipsychotics, antidepressants, mood stabilizers, benzodiazepines, barbiturates, and psychostimulants. The presence or absence of this phenomenon and the rhythm phase in the efficacy of each drug varies depending on the drug, dose, parameter measured, animal species, and strain. A recent study demonstrating circannual changes in the phases of circadian rhythm of drug efficacy suggests that discrepancies between studies may be considerably explained by the presence of a circannual rhythm. The rhythms in drug effects are suggested not to be due to rhythmic changes in the pharmacokinetics of the drugs but rather to an endogenous rhythm in drug susceptibility resulting from a circadian rhythm in the intracerebral neurotransmission system. The presence of this phenomenon and its law have been demonstrated to a considerable extent in animals, but corresponding clinical reports in humans remain insufficient despite its clinical importance. Further study in humans is certainly warranted.

Abstract
The effects of many kinds of psychotropic drugs have been shown in animal studies to follow a circadian rhythm. Trials for the clinical application of this circadian rhythm have already been undertaken. Although the mechanisms underlying this phenomenon are still unclear, chronological changes in the levels of drugs in the blood and brain suggest that it is primarily due to rhythms in the brain's susceptibility to drugs. Rhythms are present in the level of intracerebral neurotransmitters, receptors and second messengers. Each of these rhythms may cause other rhythms within each system of neurotransmitters, which in turn induces a rhythm in the susceptibility to drugs.

Abstract
The influence of the social environment on striatal dopamine D2 receptor density in the developing rat brain was investigated. Social isolation of rats from 20 to 60 days of age was associated with a decrease in the density of striatal dopamine receptors. Daily handling of the animals did not attenuate this effect. Chronic haloperidol treatment increased striatal dopamine receptor density to normal control values. Cohabitation with haloperidol-treated rats from 20 to 60 days of age was also associated with a decrease in the density of striatal dopamine D2 receptors in nondrugged animals similar to that seen in animals housed in isolation. The contribution of early life experiences to the development of normal receptor functioning is discussed.

Abstract
To investigate the possibility of chronotherapy with antidepressants for patients with depression, we gave single daily doses of clomipramine 150 mg/day to 30 patients with depression at three different times of day, i.e., morning, noon, or before bedtime, using a double-blind method over a 4-week period. Beneficial effects differed according to the administration time of day, with the most effective result being found for the administration at noon. Time-dependent differences in side effects were observed in tremors and dryness of mouth. An additional 10 patients were administered their medications three times a day by traditional, equally divided doses, and the efficacy was inferior than daily single doses at noon. The study results showed the significance of the administration time of day for the benefits and side effects of antidepressant therapy for depression.

Abstract
We have previously demonstrated a time-dependent variability in the diuretic effects of trichlormethiazide, a thiazide diuretic agent, in young rats. The study suggested that the time-dependent variations in urinary trichlormethiazide and susceptibility of renal tissues to the agent might be involved in this phenomenon. The present study was undertaken to test a hypothesis that such a daily variation in the effects of trichlormethiazide is blunted by age. Trichlormethiazide (0.5 and 2.0 mg/kg) was given orally at 1200 hrs (day trial) or at 2400 hrs (night trial) in young (10-11 week old) and aged (23-24 month old) Wistar rats. Urine was collected for 8 hours after the agent and urinary excretions of sodium, chloride and trichlormethiazide were determined. Urine volume and urinary excretions of sodium, chloride and trichlormethiazide following the agent were significantly greater at 1200 hrs than at 2400 hrs in the young rats. However these administration time-dependent changes in the effects of trichlormethiazide and its urinary amount diminished in the aged rats. In the day and night trials, there were significant correlations between urinary trichlormethiazide and its effects (urine volume, urinary sodium and chloride) in both groups of rats. The regression lines in each parameter of two trials differed in the young, but not in the aged group of rats. These data indicate that the mode of the time-dependent changes in the effects of trichlormethiazide is altered in aged Wistar rats. Dampening of the time-dependent variations in urinary trichlormethiazide and susceptibility to the agent might be involved in these chronopharmacological alterations in aged rats.

Abstract
After the chronic administration of saline, rats were treated with nomifensine (0.1 or 1.0 mg/kg, twice a day, at light and dark onset) for 11 days. The sleep-wake activity was recorded for 24 h on the baseline day (saline), on nomifensine days 1, 5 and 11, and also on day 12, when saline was injected again (withdrawal day). Another group of rats was treated with saline throughout the experiment, without significant effect on the sleep-wake activity. The smaller dose of nomifensine increased non-REM sleep (NREMS) at the expense of wakefulness (W) in the light period. The effect persisted throughout the chronic treatment. A late increase in REM sleep (REMS) was noted on nomifensine days 5 and 11. Nomifensine failed to affect the sleep-wake activity in the dark period. On withdrawal, the baseline percentages of the vigilance states were recovered. As evaluated through spectral analysis of the EEG, the increase in NREMS was accompanied by an increase in slow wave activity. The higher dose of nomifensine elicited an increase in W and a reduction in both sleep states, followed by changes in W and NREMS in the opposite directions. These effects were evident in both the light and the dark periods of the day. Chronic treatment resulted in circadian variations in the effects. Withdrawal of the drug abolished the arousal reaction, but the late increase in NREMS persisted. The dose-dependent biphasic effects of nomifensine on sleep-wake activity can be explained by considering the proposed indirect dopamine and possibly noradrenaline agonist activity of the drug.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In rats, behavioral (startle response and motor activity) and physiological (plasma corticosterone, nonesterified fatty acids, blood ethanol levels, liver alcohol and aldehyde dehydrogenase activity, and body temperature) responses to ethanol were measured over the 24-hr cycle. The response to ethanol for many of these measures showed circadian variations. Both stimulatory and inhibitory effects of ethanol were observed for several dependent variables at the same time, relative to controls. These results suggest that many discrepancies in the ethanol literature may be due to a light cycle X dependent variable interaction.

Abstract
A long-term intracarotid tube was implanted in 32 rats. Intracarotid injection of 4 different neuroleptics (haloperidol, cis- and trans-flupenthixol, clopenthixol and reserpine) elicited a typical posture with abduction of the limbs on one side and and adduction on the other. Only the neuroleptically-active cis-isomers of flupenthixol and clopenthixol provoked this dystonic reaction. The posture spontaneously vanished after 24 hr and could be antagonized with the anticholinergic biperiden. Sham injections of Ringer's solution and isotonic glucose proved to be behaviourally inert. These results indicate an asymmetric distribution of the drugs in this experimental procedure. Their implications concerning drug-induced and spontaneous dystonias as well as psythopathology are discussed.

Abstract
Striking circadian changes in behavioral sensitivity to haloperidol were found by measurements of cataleptic responses in rats trained in a controlled lighting cycle (lights on, 7:00 a.m.--7:00 p.m.). Thus, catalepsy was maximal at about 4:00 p.m. and minimal at about 4:00 a.m., virtually the opposite of the circadian rhythm of spontaneous behavioral activity in drug-free rats. At a given dose of haloperidol, catalepsy scores differed 2- to 3-fold, and the ED50 shifted left nearly 10-fold from a.m. to p.m. After fixed doses of haloperidol, tissue levels of the drug, as determined by a sensitive and selective radioreceptor assay, differed by 2- to 6-fold through the 24 hr cycle and brain levels closely followed the circadian changes in behavior. These results suggest a pharmacokinetic contribution to the circadian changes in behavioral response, although additional pharmacodynamic factors are also considered.

Abstract
Circadian fluctuation has been reported to exist to the effects of haloperidol after acute administration. In an attempt to clarify the viability of chronotherapy with haloperidol, the antiapomorphine effect of haloperidol after chronic administration was investigated in the present paper. Haloperidol was administered once daily at the same time for 21 consecutive days to rats which were kept under 12 hr lighting conditions with light onset at 19:30. Then the chronology of the antiapomorphine effect was investigated. The antiapomorphine effect was significantly stronger in the group treated at 19:30 than that treated at 13:30. These data agreed with the results found after the acute administration of the drug. After chronic administration, no difference was found in the plasma and brain level of haloperidol due to the time of administration. These experimental results seem to suggest that a circadian rhythm in the brain susceptibility to haloperidol exists even during chronic administration.

Abstract
Circadian changes in behavioral responses to haloperidol were evaluated in rats under normal and altered lighting cycles. There was a 5.5-fold change in ED50 between the maximum (4 PM) and minimum (4 AM) cataleptic response to the drug under normal lighting (lights of 7 AM- 7 PM). The rhythm was present whether the same rats were tested repeatedly, or fresh rats were used at each time to avoid drug effects which persist for at least several days. Under normal lighting, the maximum cataleptic effect of haloperidol corresponded closely to the light-phase minimum of spontaneous motor activity in untreated rats. Measures of sedation (ptosis and motor inhibition) induced by haloperidol yielded small circadian rhythms under normal lighting and were highly dependent on the baseline level of arousal. A month of constant light or dark, or reversed dark-light cycles had small effects on the sedative actions of haloperidol, although inhibition of locomotion tended to phase-shift with general arousal; these changes did not alter the catalepsy rhythm. While the circadian rhythm of spontaneous activity underwent a complete reversal within 1 month (t 1/2 =17 days) of reversed lighting cycles, the catalepsy rhythm changed very gradually (t 1/2 = 82 days) and required nearly 6 months for complete reversal. Thus, catalepsy is a robust endogenously regulated circadian response that is only slowly influenced by altered lighting conditions which dissociate this rhythm of neuroleptic response from that of spontaneous general arousal. Endogenous neurobiologic and pharmacokinetic factors may contribute to circadian changes in neuroleptic responses.

Abstract
Circadian fluctuations were measured in the head twitch response produced by 5-methoxy-N1,N1-dimethyltryptamine (5-MeODMT) and p-chloroamphetamine (PCA) in male BK. TO mice. The effects of depleting brain 5-hydroxytryptamine (5-HT) with p-chlorophenylalanine (PCPA) on the 5-MeODMT in the mouse were also studied. Changes in brain 5-HT and 5-hydroxyindoleacetic (5-HIAA) were concomitantly determined. PCPA (400 mg/kg IP twice on consecutive days) significantly increased the number of head twitches induced by 5-MeODMT (5 mg/kg IV) on days 3 and 5 after the initial injection of PCPA when 5-HT and 5-HIAA were also significantly reduced. On day 12, there was no significant difference in the number of head twitches between mice administered PCPA and those given saline, and 5-HT and 5-HIAA levels were nearly back to normal. PCPA, using the same dose schedule, significantly reduced the number of head twitches induced by PCA when PCA was administered 24 h after the second injection of PCPA (day 3. Mice maintained on a 12-h light-dark cycle showed a maximum response to the direct 5-HT receptor agonist 5-MeODMT (5 mg/kg IV) towards the end of the dark period, when the 5-HT level was at its lowest. p-Chloroamphetamine, which causes release of 5-HT from pre-synaptic neurones, produced a peak head twitch response in the middle of the light period when 5-HT and 5-HIAA levels were maximal, while the response towards the end of the dark period was significantly less than that at other times tested. It is concluded that 5-HT receptor response shows a circadian rhythm related to both pre-synaptic availability of 5-HT and post-synaptic receptor sensitivity.

Abstract
To investigate diurnal variations in dopamine receptor binding, the amount of specifically bound 3H-spiroperidol was measured at 4-h intervals over a 24-h period in the striatum of rats which had been housed under a controlled 12-h light-dark cycle (lights on 7 a.m.). A highly significant ultradian rhythm with peaks at 2 a.m. and 2 p.m. was found with an amplitude of about 75%. Chronic imipramine modified the rhythm such that the two peaks occurred 4 h later and amplitude as well as 24-h mean of binding decreased. Scatchard analysis at times of least and greatest binding indicated that the differences in binding were due not to changes in the affinity, but in the number of binding sites. These results are interpreted with regard to the mode of action of psychoactive drugs and to postulated changes of receptor sensitivity in neurological and psychiatric disorders.
