1. Behavioral effects of Bj-PRO-7a, a proline-rich oligopeptide from Bothrops jararaca venom
The heptapeptide Bj-PRO-7a, isolated and identified from Bothrops jararaca (Bj) venom, produces antihypertensive and other cardiovascular effects that are independent on angiotensin converting enzyme inhibition, possibly relying on cholinergic muscarinic receptors subtype 1 (M1R). However, whether Bj-PRO-7a acts upon the central nervous system and modifies b

2. Antinociceptive effect of semi-purified petroleum ether partition of Muntingia calabura leaves
ABSTRACT Muntingia calabura L., Muntingiaceae, is a medicinal plant for various pain-related diseases. The aims of the present study were to determine the antinociceptive profile and to elucidate the possible mechanisms of antinociception of petroleum ether partition obtained from crude methanol extract of M. calabura leaves using various animal models. The

3. β-Citronellol, an alcoholic monoterpene with inhibitory properties on the contractility of rat trachea
β-Citronellol is an alcoholic monoterpene found in essential oils such Cymbopogon citratus (a plant with antihypertensive properties). β-Citronellol can act against pathogenic microorganisms that affect airways and, in virtue of the popular use of β-citronellol-enriched essential oils in aromatherapy, we assessed its pharmacologic effects on the contracti

4. Lack of an association between SNPs within the cholinergic receptor genes and smoking behavior in a Czech post-MONICA study
Smoking has a significant heritable component of approximately 30-60%. Recent genome wide association studies have identified single nucleotide polymorphisms (SNPs) within the nicotinic cholinergic receptor subunits 3 (rs578776), 5 (rs16969968) and β3 (rs6474412), which are associated with nicotine dependence in Western European populations. To analyze the

5. 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

6. Cardiovascular effects of the intracerebroventricular injection of adrenomedullin: roles of the peripheral vasopressin and central cholinergic systems
Our objective was to investigate in conscious Sprague-Dawley (6-8 weeks, 250-300 g) female rats (N = 7 in each group) the effects of intracerebroventricularly (icv) injected adrenomedullin (ADM) on blood pressure and heart rate (HR), and to determine if ADM and calcitonin gene-related peptide (CGRP) receptors, peripheral V1 receptors or the central cholinerg

7. Sistema colinérgico: revisitando receptores, regulação e a relação com a doença de Alzheimer, esquizofrenia, epilepsia e tabagismo
OBJETIVO: Revisar a estrutura e o funcionamento do sistema colinérgico central ressaltando seu papel na fisiologia e na fisiopatologia das doenças de Alzheimer e Parkinson, esquizofrenia, epilepsia e tabagismo. MÉTODO: Foi realizada uma pesquisa bibliográfica no MedLine, LILACS, PubMed e ISI, e na Biblioteca da Fundação Oswaldo Cruz, RJ, selecionando-s

8. Antidipsogenic effects of central adenosine-5'-triphosphate
Besides other physiological functions, adenosine-5'-triphosphate (ATP) is also a neurotransmitter that acts on purinergic receptors. In spite of the presence of purinergic receptors in forebrain areas involved with fluid-electrolyte balance, the effect of ATP on water intake has not been investigated. Therefore, we studied the effects of intracerebroventricu

9. Temporal effects of nicotine and ethanol combined exposure on cholinergic system of the adolescent brain / Curso temporal dos efeitos da exposição combinada de nicotina e etanol no sistema colinérgico cerebral durante adolescência
Nicotine and ethanol are the most commonly consumed drugs. As clearly indicated by epidemiological studies, there is a close interrelationship between smoking and alcohol consumption manly during adolescence period. However, there are few studies on the basic neurobiology of the effects of the combined nicotine and ethanol exposure in the adolescent brain. S

10. Effects of neuronal nitric oxide synthase inhibition on cardiovascular responses elicited by cholinergic receptors stimulation within the Nucleus of the Solitary Tract of non-anesthetized rats. / Efeitos da inibição da óxido nítrico sintase neuronal sobre as respostas cardiovasculares causadas pela estimulação de receptores colinérgicos nos Núcleos do Tracto Solitário de ratos não anestesiados.
O NTS é o sítio primário das terminações das aferências dos reflexos cardiovasculares no sistema nervoso central (SNC). A presença da acetilcolina (ACh) no NTS e sua participação na transmissão ou modulação central das funções neurovegetativas foi sugerida desde a década de 80 (Kobayashi et al., 1978; Simon et al., 1981; Criscione et al., 1983

11. Purinergic signalling: past, present and future
The discovery of non-adrenergic, non-cholinergic neurotransmission in the gut and bladder in the early 1960's is described as well as the identification of adenosine 5'-triphosphate (ATP) as a transmitter in these nerves in the early 1970's. The concept of purinergic cotransmission was formulated in 1976 and it is now recognized that ATP is a cotransmitter i

12. Participação da área septal medial nas respostas sialogoga, dipsogênica e cardiovascular induzidas pela pilocarpina
Peripheral injection of pilocarpine (PILO, 1 mg/Kg of body weight), muscarinic cholinergic agonist, induce salivation, water intake and pressor response. The medial septal area (MSA) is an important brain area involved in cardiovascular regulation and hydroelectrolytic control. In this present study, we investigated: 1) the effect of MSA electrolytic lesion
