A Histological Assessment of the Cell Death Induced by Haloperidol on Prefrontal Cortex
Provedor de dados: 77
Autores: Ghanbari,Ali; Kakebaraei,Seyran; Khazaei,Mozafar.
Neuroleptic drugs such as haloperidol has side effects on extrapyramidal pathways. Tardive Dyskinesia is the most important complication. The most characteristic feature of this Tardive Dyskinesia is involuntary movements of mouth and face. In regard to this problem, the induction of gliosis and cell death in the nervous tissue are considered. In this study, adult Sprague-Dawley rats were used as experimental models. Rats were divided into control and experimental groups. The rats were kept in the animal house under standard conditions during experiments. The control rats were intraperitoneally treated with normal saline for 6 days. The experimental samples were treated for the same time with 2, 5 and 10 mg haloperidol. After the trial period, the rats...

Modulation of post-coital dopaminergic tone by prior parity
Provedor de dados: 52
Autores: Sider,Lucia Helena; Hucke,Erica Engelberg Teixeira da Silva; Felicio,Luciano Freitas.
The aim of this study was to investigate the possible effects of reproductive experience on dopaminergic profile in three different brain tissues, hypothalamus, striatum and cortex in rats on 7th-8th day of pregnancy during the light-dark shift (between 1700-1900h). Results showed that in hypothalamus, dopamine levels increased and DOPAC/DA decreased as a function of parity. In cortex, no differences were observed. In striata, the haloperidol-induced HVA and HVA/DA increases were less intense in experienced animals. These findings suggested that reproductive experience produced functional central changes during pregnancy, with different neurochemical responses depending on the brain region.

A double-blind comparison of the effect of the antipsychotics haloperidol and olanzapine on sleep in mania
Provedor de dados: 56
Autores: Moreno,R.A.; Hanna,M.M.; Tavares,S.M.; Wang,Y .P.
The effects of haloperidol and olanzapine on polysomnographic measures made in bipolar patients during manic episodes were compared. Twelve DSM-IV mania patients were randomly assigned to receive either haloperidol (mean ± SD final dosage: 5.8 ± 3.8 mg) or olanzapine (mean ± SD final dosage: 13.6 ± 6.9 mg) in a 6-week, double-blind, randomized, controlled clinical trial. One-night polysomnographic evaluation was performed before and after the haloperidol or olanzapine treatment. Psychopathology and illness severity were rated respectively with the Young Mania Rating Scale (YMRS) and the Clinical Global Impressions - Bipolar version (CGI-BP). There was a significant improvement in the YMRS and CGI-BP scores at the end of the study for both groups. Mixed...

Acute buspirone abolishes the expression of behavioral dopaminergic supersensitivity in mice
Provedor de dados: 56
Autores: Queiroz,C.M.T.; Alcântara,F.B.; Yagüe,A.M.L.; Bibancos,T.; Frussa-Filho,R.
Previous studies have shown that rats withdrawn from long-term treatment with dopamine receptor blockers exhibit dopaminergic supersensitivity, which can be behaviorally evaluated by enhanced general activity observed in an open-field. Recently, it has been reported that co-treatment with the non-benzodiazepine anxiolytic buspirone attenuates the development of haloperidol-induced dopaminergic supersensitivity measured by open-field behavior of rats. The aims of the present study were: 1) to determine, as previously reported for rats, if mice withdrawn from long-term neuroleptic treatment would also develop dopaminergic supersensitivity using open-field behavior as an experimental paradigm, and 2) to examine if acute buspirone administration would...

Sawtooth waves during REM sleep after administration of haloperidol combined with total sleep deprivation in healthy young subjects
Provedor de dados: 56
Autores: Pinto Jr.,L.R.; Peres,C.A.; Russo,R.H.; Remesar-Lopez,A.J.; Tufik,S.
We sought to examine the possible participation of dopaminergic receptors in the phasic events that occur during rapid eye movement (REM) sleep, known as sawtooth waves (STW). These phasic phenomena of REM sleep exhibit a unique morphology and, although they represent a characteristic feature of REM sleep, little is known about the mechanisms which generate them and which are apparently different from rapid eye movements. STW behavior was studied in 10 male volunteers aged 20 to 35 years, who were submitted to polysomnographic monitoring (PSG). On the adaptation night they were submitted to the first PSG and on the second night, to the basal PSG. On the third night the volunteers received placebo or haloperidol and spent the whole night awake. On the...
