1. Antidiarrheal effect of extract from the bark of Combretum leprosum in mice
Abstract This study investigated the effects of the ethanolic extract from the bark of Combretum leprosum (ECL) on intestinal transit and castor-oil induced diarrhea in mice. The oral administration of ECL (750 and 1000 mg/kg) slowed intestinal transit (ID50 of 455 mg/kg). The ECL (250-1000 mg/kg) reduced castor-oil induced diarrhea, in a time- and dose-depe

2. A spider derived peptide, PnPP-19, induces central antinociception mediated by opioid and cannabinoid systems
Abstract Background Some peptides purified from the venom of the spider Phoneutria nigriventer have been identified as potential sources of drugs for pain treatment. In this study, we characterized the antinociceptive effect of the peptide PnPP-19 on the central nervous system and investigated the possible involvement of opioid and cannabinoid systems in i

3. Possible mechanisms of antinociception of methanol extract of Melastoma malabathricum leaves
ABSTRACT Melastoma malabathricum L., Melastomaceae, has been traditionally used to relieve diverse pain-related ailments. The objectives of the present study were to determine the antinociceptive activity of methanol extract of M. malabathricum leaves and to elucidate the possible mechanisms of antinociception involved using various rats' models. The extract

4. 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

6. Antinociceptive and anti-inflammatory activities of an aqueous extract of Chiliotrichum diffusum
The flowers of the Chiliotrichum diffusum (G. Forst.) Kuntze, Asteraceae, have long been used in traditional medicine and rituals. In this study, the anti-inflammatory and antinociceptive activities of a decoction of the flowers were evaluated and a phytochemical analysis was performed by HPLC-DAD. In order to evaluate the antinociceptive activity, the aceti

7. Effects of terlipressin and naloxone compared with epinephrine in a rat model of asphyxia-induced cardiac arrest
OBJECTIVE: To evaluate the hemodynamic and metabolic effects of terlipressin and naloxone in cardiac arrest. METHODS: Cardiac arrest in rats was induced by asphyxia and maintained for 3.5 minutes. Animals were then resuscitated and randomized into one of six groups: placebo (n = 7), epinephrine (0.02 mg/kg; n = 7), naloxone (1 mg/kg; n = 7) or terlipressi

8. Atividade antinociceptiva e anti-inflamatória do sesquiterpeno nerolidol em camundongos. / Antinociceptive and anti-inflammatory activities of the sesquiterpeno nerolidol in mice.
Nerolidol, an acyclic sesquiterpene found as the major component in several essential oils, has antineoplastic, antimicrobial and antileishmanial activities, however its action in painful processes has never been studied. This study investigated the antinociceptive and anti-inflammatory activities of nerolidol in experimental pain and inflammation models in

9. Uso do exercício resistido antagonizado por naloxone como fator de analgesia em sinovite aguda de joelho de ratos Wistar
A analgesia advinda do exercício físico pode ocorrer via liberação de opioides endógenos, no sistema nervoso central e na periferia. Contudo, a literatura ainda é controversa sobre vias e ações do exercício na dor. Assim, o objetivo da pesquisa foi avaliar se o exercício resistido produz alterações sobre o quadro nociceptivo e se sofre interferê

10. Percutaneous sciatic nerve block with tramadol induces analgesia and motor blockade in two animal pain models
Local anesthetic efficacy of tramadol has been reported following intradermal application. Our aim was to investigate the effect of perineural tramadol as the sole analgesic in two pain models. Male Wistar rats (280-380 g; N = 5/group) were used in these experiments. A neurostimulation-guided sciatic nerve block was performed and 2% lidocaine or tramadol (1.

11. Efeitos hemodinâmicos e metabólicos da terlipressina ou naloxona na ressuscitação cardiopulmonar: estudo experimental, randomizado e controlado / Hemodynamic and metabolic effects of terlipressin or naloxone in cardiopulmonary resuscitation: an experimental, randomized and controlled trial
Introdução: O prognóstico da parada cardiorrespiratória (PCR) em ritmo não chocável (assistolia/atividade elétrica sem pulso) é ruim e não melhorou significativamente nas últimas décadas. Embora a epinefrina seja o vasopressor recomendado, há evidências de que ela eleva o consumo de oxigênio, reduz a pressão de perfusão subendocárdica, causa

12. Arcaine-induced state-dependent memory involves opioid mechanisms in rats / ENVOLVIMENTO DO SISTEMA OPIÓIDE NA DEPENDÊNCIA DE ESTADO INDUZIDA PELA ARCAÍNA EM RATOS
Arcaine is a competitive antagonist of the polyamine binding site at the NMDA receptor which induces state-dependent recall. However, no study has addressed the involvement of other neurotransmitter/neuromodulators in arcaine-induced state dependency. The current study investigates whether the opioid system is involved in arcaine-induced state-dependent memo
