1. Antidepressant-like effect of Hoodia gordonii in a forced swimming test in mice: evidence for involvement of the monoaminergic system
Hoodia gordonii is a plant species used traditionally in southern Africa to suppress appetite. Recently, it has been associated with a significant increase in blood pressure and pulse rate in women, suggesting sympathomimetic activity. The present study investigated the possible antidepressant-like effects of acute and repeated (15 days) administration of H

2. Evaluation of neurotransmitters involved in the anxiolytic and panicolytic effect of the aqueous fraction of Paullinia cupana (guaraná) in elevated T maze
This study investigated the effects of repeatedly administration of an aqueous fraction of Paullinia cupana Kunth, Sapindaceae (guaraná) seeds (8 mg/kg) on rats submitted to the elevated T-maze, model of generalized anxiety and panic disorders. The selective serotonin reuptake inhibitor paroxetine (3 mg/kg), was used as a positive control. To evaluate possi

3. Envolvimento de mecanismos dopaminérgicos na expressão do medo condicionado contextual em ratos / Involvement of dopaminergic mechanisms in the expression of contextual conditioned fear in rats
É reconhecido que as experiências que geram reações de medo são praticamente indeléveis do encéfalo dos organismos e que condicionamentos aversivos suscitam inúmeras respostas defensivas, como o congelamento, sendo esta resposta um indicador de medo em roedores. Vários trabalhos têm apontado para a relação entre alterações na transmissão dopam

4. InvestigaÃÃo da aÃÃo central do carvacrol em modelos de ansiedade, depressÃo e convulsÃo em camundongos e possÃveis mecanismos farmacolÃgicos envolvidos. / Investigation of central actions of carvacrol in animal models of anxiety, depression and convulsion in mice and possible pharmacological mechanisms involved.
Carvacrol (5-Isopropyl-2-methylphenol) is a monoterpenic phenol present in the essencial oil of many plants. It is the major component of the essential oil fraction of oregano and thyme. This work presents the behavioral effects of carvacrol in animal models of anxiety, depression, sedation and convulsion, such as, elevated plus maze (EPM), open field, rota

5. Mecanismos dopaminérgicos na aquisição e expressão do medo condicionado: envolvimento de receptores D1 e D2 / Dopaminergic mechanisms in the acquisition and expression of conditioned fear: involviment of D1 and D2 receptors
The increase in the startle reflex in the presence of a stimulus that has been previously paired to footshock is taken as an index of fear and named fear potentiated startle (FPS). Freezing behavior, a cessation of all observable movements, except those associated with respiration, has also been used as an index of fear in rats. A growing body of evidence ha

6. Neuroendocrine mechanisms evolved in Nellore Heifers puberty / Mecanismos neuroendócrinos envolvidos na puberdade de novilhas da raça Nelore
O presente trabalho teve por objetivo investigar a variação na secreção de LH em resposta ao tratamento com neurotransmissores, na presença ou não de esteróides gonadais e desta forma gerar informações sobre os mecanismos neuroendócrinos envolvidos na maturação sexual de novilhas da raça Nelore. A concentração de LH foi quantificada por radioi

7. Study of Pharmacological Effects of (O-Methyl)-N-2,6-dihydroxy-benzoyl-tyramine (riparin III) from Aniba riparia (Nees) Mez (Lauraceae) on behavioral models of anxiety and depression in mice / Estudo dos efeitos farmacolÃgicos de (O-METIL)-N-2,6-Dihidroxi-benzoil Tiramina (Riparina III) de Aniba Riparia (NEES) mez (Lauraceae) em modelos comportamentais de ansiedade e depressÃo em camundongos
Riparin III, an alkamide isolated from unripe fruit of Aniba riparia, was evaluated in animal classical models for screening of new drugs in anxiety, depression, sedation and convulsion, such as, open field, rota rod, plus maze, hole board, forced swimming, tail suspension, apomorphine-induced hypothermia, pentobarbital-induced sleeping time and pentilenotet

8. Conduta na coréia reumática: um estudo observacional
FUNDAMENTOS: A patogenia da coréia reumática relaciona-se a um mecanismo imunomediado. OBJETIVOS/MÉTODOS: A fim de verificar se este conhecimento resultou em mudanças na terapêutica desta doença, elaborou-se um estudo descritivo. RESULTADOS: Foram revistos os prontuários de 20 crianças (13 meninas) entre 6 e 12 anos de idade (média 8 anos), com diag

9. Dopaminergic modulation of grooming behavior in virgin and pregnant rats
Dopamine receptors are involved in the expression of grooming behavior. The pregnancy-induced increase in self-licking observed in rats is important for mammary gland development and lactation. This study focuses on the role of dopamine receptor subtypes in grooming behavior of virgin and pregnant female rats. General and mammary gland grooming were measured

10. A double blind trial of sulpiride in Huntington's disease and tardive dyskinesia.
Eleven patients with Huntington's disease and nine patients with tardive dyskinesia participated in a randomised double-blind crossover trial of sulpiride (as sole antidopaminergic therapy) versus placebo. Although functional improvement was not seen in Huntington's disease patients, sulpiride reduced movement count and total dyskinesia score in both conditi

11. Sulpiride in tardive dyskinesia.
The abnormal involuntary movements in tardive dyskinesia can be reduced by the dopamine antagonist drugs, phenothiazines and butyrophenones, but most cause an increase in Parkinsonian signs. Sulpiride, a benzamide derivative, and selective antagonist of D2 receptors had a significantly beneficial effect on most of 15 patients (p less than 0.01). In 12 patien

12. Body reactions during chain saw work.
Body reactions during chain saw work were studied in 14 subjects. The subjects divided into three groups (control, sulpiride, and propranolol) successively cut down logs with a chain saw for seven minutes. The start of the sawing led to a pronounced increase in heart rate which persisted during the sawing. The groups taking sulpiride and propranolol showed a
