1. 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

2. Avaliação da ação espasmolítica do flavonoide 3,6-Dimetil éter galetina, isolado de Piptadenia stipulacea (Benth.) Ducke e investigação do mecanismo de ação em traqueia de cobaia e aorta de rato / Evaluation of spasmolytic action of the flavonoid galetin 3,6-dimethyl ether isolated from Piptadenia stipulacea (Benth.) Ducke and investigation of the mechanism of action in guinea pig trachea and rat aorta
O flavonoide 3,6-dimetil éter galetina (FGAL) foi isolado das partes aéreas de Piptadenia stipulacea (Benth.) Ducke e foi investigada sua possível atividade hemolítica em eritrócitos de rato e espasmolítica em vários músculos lisos isolados como útero de rata, íleo e traqueia de cobaia, e aorta de rato. FGAL não causou efeito hemolítico em eritr�

3. Estudo do efeito relaxante de um novo composto doador de óxido nítrico em preparações de traquéias isoladas de ratos / Study of the relaxing effect of a new nitric oxide donor compound in preparations of isolated rat tracheae
This study evaluated the mechanisms of relaxation of two nitric oxide (NO) donors, ruthenium complex [Ru(terpy)(bdq)NO+]3+ (Terpy) and sodium nitroprusside (SNP) in isolated trachea of rats. The isolated trachea was sectioned into rings and contracted with carbachol in an organ chamber. The relaxing effect of Terpy and SNP was evaluated at increasing concent

6. Participação Do Cálcio Citosólico Sobre A Ação Espasmolítica Do Ácido Ent-7a-Acetoxitraquiloban-18-Óico E De Seu Derivado Hidroxilado Em Íleo Isolado De Cobaia / Partipation of cytosolic calcium in spasmolytic action of ent-7a-acetoxytrachyloban-18-oic acid and its hidroxylated derivated on guinea-pig ileum
From the stem bark of Xylopia langsdorfiana A. St.-Hil. &Tul. (Annonaceae), popularly known as pimenteria da terra, was isolated the diterpene ent-7-α-acetoxytrachyloban-18-oic acid (trachylobane-360) from which it was made a structural modification in which the acetoxy group was substituted by hydroxy generating the ent-7a-hidroxitrachyloban-18-oic aci

7. Inibição da contratilidade do músculo liso traqueal de ratos por um diterpeno caurano isolado de Croton argyrophylloides / Inhibition of tracheal smooth muscle contractility of rats by a diterpene isolated from Croton caurano argyrophylloides
Diversos diterpenos cauranos isolados de extratos de plantas têm mostrado ação antiespasmódica em diferentes músculos lisos. Nesse estudo, avaliamos os efeitos do rel-(1S, 4aS, 7S, 8aS)-7-(1-vinil)-tetradecahidro-1,4a-dimetilfenantreno-7,8a carbolactona-1-carboxílico (ATCC), um novo diterpeno caurano recentemente isolado de Croton argyrophylloides, em

10. Distribution of galanin immunoreactivity in the respiratory tract of pig, guinea pig, rat, and dog.
Galanin, a newly discovered peptide isolated from porcine intestine, is known to cause contraction in rat smooth muscle preparations and to induce hyperglycaemia in dogs. By the use of radioimmunoassay and immunohistochemical techniques the concentration and distribution of galanin immunoreactivity were determined in several areas of the respiratory tract of
