We recently proposed that alcoholics suffer from a functional defect within the basal ganglia/limbic striatum or its modulation by dopaminergic projections from the ventral tegmentum, and that inhibition of striatal output caused by the prodopaminergic effects of alcohol ingestion induces or exacerbates craving and impaired control over alcohol consumption in alcoholic individuals. To test this...
The development of cortical neurons in vivo and in vitro is accompanied by alterations in NMDA receptor subunit expression and concomitant modifications in the pharmacological profile of NMDA-activated ionic currents. For example, we observed that with decreasing NR2B/NR2A subunit expression ratio, the block of NMDA receptor-mediated whole-cell responses by the NR2B-selective antagonist haloper...
BACKGROUND Herbal medicines have been used to treat PD in ancient medical systems in Asian countries such as India, China, Japan and Korea based on their own anecdotal or experience-based theories. Mucuna pruriens commonly known asvelvet beans, or cow itch, are used in case of spasms associated with Parkinsonism. PURPOSE To investigate the antiparkinsonism activity of hydro alcoholic root ext...
Effect of administration of Rice bran oil (RBO) was evaluated on haloperidol elicited tardive dyskinesia in rats. Albino Wistar rats treated with haloperidol in drinking water at a dose of 0.2mg/kg/day and RBO by oral tubes at a dose of 0.4 mL/day for 5 weeks. Motor coordination, VCMs and 8-hydroxy-2-(di-n-propylamino) tetraline)[8-OH-DPAT] _syndrome were monitored. Striatal serotonin (5-hydrox...
Although emotional dysfunction in patients with schizophrenia is thought to be associated with poorer outcomes in terms of overall quality of well-being, only a few basic studies have examined the biochemical effect of antipsychotics on emotional function. In this investigation, we examined differences in the effects of aripiprazole and haloperidol on the conditioned fear response in methamphet...
Reduced glutamate-mediated synaptic transmission has been implicated in the pathophysiology of schizophrenia. Because antipsychotic agents might exert their beneficial effects against schizophrenic symptoms by strengthening excitatory transmission in critical dopaminoceptive brain areas, in the present study we have studied the effects of acute and chronic haloperidol treatment on striatal syna...
OBJECTIVE The study was designed to assess the predictive relationship between brain structure volume and positive and negative symptom response to clozapine and haloperidol. METHOD Partially responsive outpatients with schizophrenia who participated in a 10-week, parallel-group, double-blind comparison of clozapine and haloperidol and who had an available magnetic resonance imaging scan were...
Cholecystokinin (CCK) and dopamine (DA) coexist in a subpopulation of neurons of the ventral tegmental area projecting to the nucleus accumbens. The present experiments were undertaken to determine the effect of acute and long-term administration of haloperidol on the responsiveness of accumbens neurons to microiontophoretic applications of the sulfated cholecystokinin octapeptide (CCK-8S), kai...
S 16924 showed a pattern of interaction at multiple (>20) native, rodent and cloned, human (h) monoaminergic receptors similar to that of clozapine and different to that of haloperidol. Notably, like clozapine, the affinity of S 16924 for hD2 and hD3 receptors was modest, and it showed 5-fold higher affinity for hD4 receptors. At each of these sites, using a [35S]GTPgammaS binding procedure, S ...
OBJECTIVE To compare the risk of in-hospital mortality associated with haloperidol compared with atypical antipsychotics in patients admitted to hospital with acute myocardial infarction. DESIGN Cohort study using a healthcare database. SETTING Nationwide sample of patient data from more than 700 hospitals across the United States. PARTICIPANTS 6578 medical patients aged more than 18 year...
