1. Pharmacological evaluation of bee venom and melittin
The objective of this study was to identify the pharmacological effects of bee venom and its major component, melittin, on the nervous system of mice. For the pharmacological analysis, mice were treated once with saline, 0.1 or 1.2 mg/kg of bee venom and 0.1 mg/kg of melittin, subcutaneously, 30 min before being submitted to behavioral tests: locomotor activ

2. Animal models for predicting the efficacy and side effects of antipsychotic drugs
The use of antipsychotic drugs represents an important approach for the treatment of schizophrenia. However, their efficacy is limited to certain symptoms of this disorder, and they induce serious side effects. As a result, there is a strong demand for the development of new drugs, which depends on reliable animal models for pharmacological characterization.

3. Análise da interação entre acetilcolina, dopamina e óxido nítrico sobre o comportamento motor em um modelo animal da doença de Parkinson
O objetivo deste trabalho foi avaliar a interação entre os neurotransmissores acetilcolina, dopamina e óxido nítrico nos núcleos basais de camundongos. Foram realizados quatro experimentos, com seis grupos, com oito camundongos suíços, machos, pesando entre 20-30g. No Experimento 1, os animais receberam injeção intraperitoneal (i.p.) de salina ou ha

4. Antiasthmatic and antiallergic potential of methanolic extract of leaves of Ailanthus excelsa
The aim of study was antiasthmatic potential of methanolic extract of leaves of Ailanthus excelsa Roxb., Simaroubaceae. Traditionally or in Indian system of medicine, A. excelsa is used in the treatment of asthma, cough, colic pain, cancer, diabetes and also used as antispasmodic, antifertility, bronchodilator. Stem bark of A. excelsa already reported for it

5. INFLUÊNCIA DO ÔMEGA 3 SOBRE SINTOMAS EXTRAPIRAMIDAIS, DEFICIÊNCIA COGNITIVA E PARÂMETROS DE ESTRESSE OXIDATIVO EM ANIMAIS TRATADOS COM NEUROLÉPTICOS
Haloperidol and fluphenazine are typical neuroleptics widely used in the treatment of mental illness, whose chronic use is associated with adverse effects that affect the motor function and memory, among others. The motor disturbances can be moderate, and include parkinsonism, akathisia, dystonia, but also a more severe syndrome, known as tardive dyskinesia

6. O papel do sistema dopaminérgico nigroestriatal na neurobiologia do sono / The role of the dopaminergic nigrostriatal system in the sleep neurobiology.
Dopamine (DA) is critically involved in regulating neural processes responsible for complex movements and emotions. Alterations in central dopaminergic neurotransmission have been implicated in important neurological and psychiatric disorders such as Parkinsons disease (PD) and schizophrenia. In addition, DA has recently been recognized as instrumental in th

7. Acute effects of selective serotonin reuptake inhibitors on neuroleptic-induced catalepsy in mice
Depression found in Parkinson disease (PD) usually responds to selective serotonin reuptake inhibitors (SSRIs). Drugs that modify experimental neuroleptic catalepsy (NC) might affect extrapyramidal symptoms in PD. Therefore, the effects of SSRIs on NC were tested in mice, 26-36 g, separated by sex. Catalepsy was induced with haloperidol (H; 1 mg/kg, ip) and

8. Ginkgo biloba leaf extract (EGb 761) enhances catalepsy induced by haloperidol and L-nitroarginine in mice
Ginkgo biloba extract EGb 761 has been reported to have therapeutic effects which have been attributed to anti-oxidant and free radical-scavenging activities, including a direct action on nitric oxide production. L G-nitro-arginine (L-NOARG), a nitric oxide synthase inhibitor, and haloperidol, a drug that blocks dopamine receptors, are both known to induce c

9. Ação de drogas agonistas e antagonistas dos sistemas colinérgico e dopaminégico: estudo comportamental e neuroquímico em corpo estriado de rato. / The action of the agonists and antagonists drugs of cholinergic and dopaminergic systems: behavioral and neurochemical study in striatum of rats
In the study, the interaction between the dopaminergic and cholinergic systems through the study of behavioral (open field and catalepsy) and neurochemical (density of dopaminergic receptor (D1 and D2-like) and muscarinic (M1+M2-like)) effect in striatum rat was evaluated. The following drugs were used: mazindol (indirect dopaminergic agonist), apomorphine (

10. Dopaminergic profile of new heterocyclic N-phenylpiperazine derivatives
Dopamine constitutes about 80% of the content of central catecholamines and has a crucial role in the etiology of several neuropsychiatric disorders, including Parkinson's disease, depression and schizophrenia. Several dopaminergic drugs are used to treat these pathologies, but many problems are attributed to these therapies. Within this context, the search

11. Gender-related differences in the effects of nitric oxide donors on neuroleptic-induced catalepsy in mice
It has been suggested that nigrostriatal dopaminergic transmission is modulated by nitric oxide (NO). Since there is evidence that gonadal hormones can affect extrapyramidal motor behavior in mammals, we investigated the effects of isosorbide dinitrate (ISD), linsidomine (SIN-1) and S-nitroso-N-acetylpenicillamine (SNAP), three pharmacologically different NO

12. Evaluation of the central activity of the ethanolic extract of Acosmium subelegans (Mohlenbr) in mice
The ethanolic extract (EE) of Acosmium subelegans (Mohlenbr) Yakovl (perobinha-do-campo) was tested to behavioral paradigms in mice to investigate its putative central depressant effect. Oral pretreatment with the EE significantly reduced in a dose-dependent way the locomotor activity and increased by 30-55% the barbiturate sleep duration relatively to contr
