3. Erythroxylum pungens elicits vasorelaxation by reducing intracellular calcium concentration in vascular smooth muscle cells of rats
The cardiovascular effects elicited by the ethanolic extract obtained from the roots of Erythroxylum pungens O.E. Schulz, Erythroxylaceae (EEEP) and the vasorelaxant effect induced by its main tropane alkaloid (pungencine) were investigated. In normotensive rats, administration of EEEP (1, 10, 30 and 60 mg/kg i.v., randomly) produced dose-dependent hypotensi

4. Estudo de toxicidade reprodutiva e potencial mutagênico de fitoterápico contendo Cinchona calisaya, Jateorhiza palmata, Centaurim erythraea, Baccharis trimera, Artemisia absinthium, Matricaria recutita e Cinnamomum cassia / Study of the reproductive toxicity and mutagenic potential of a herbal medicine containing Cinchona calisaya; Jateorhiza palmata, Centaurim erythraea, Baccharis trimera, Artemisia absinthium, Matricaria recutita and Cinnamomum cassia
The use of medicinal plants is widespread, and most herbal medicines are marketed for sale without prescription. One of the main problems in the use of these products is the belief that plant products are free of toxic effects. Pregnant women constitute a group that traditionally uses herbal medicines, believing that they cause no damage to the fetus. The he

5. Aquisição de fonologia : a influiência do acento e o preenchimento de unidades prosódicas em dados de fala de duas crianças entre 1;0.4 e 2;1.10 de idade, em contato com o português brasileiro falado em Alagoas e Pernambuco. / Acquisition of phonology: the influience accent and segment completion of prosodic units in speech data from two children between the ages of 1;0.4 e 2;1.10 and who were exposed to Brazilian Portuguese spoken in the states of Alagoas and Pernambuco.
The study delves into the influence of accent and segment completion of prosodic units in speech data from two children between the ages of 1;0.4 and 2;1.10 and who were exposed to Brazilian Portuguese spoken in the states of Alagoas and Pernambuco. It was hypothesized that grammatical processing stems from two concurrent movements in opposing directions dur

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. Efeitos pré e pós sinápticos dos inibidores da acetilcolinesterase na neurotransmissão em musculatura lisa.
Justification: The present work considers the effects of new inhibitors of acetylcholinesterase (AChE) on the reactivity and neurotransmission in rats and mice. The new anticholinesterase compounds, ITH12118 and ITH12117, have an hybrid stucture, derived from the molecule of of the anticholinesterase Tacrine and the 1,4 dihydropyridine nimodipine, a blocker

10. Efeitos da injeção de moxonidina no controle da ingestão de sódio e regulação cardiovascular.
Deficit of water and sodium in the body is detected by receptors located in different parts of the body. These receptors or hormones signalize to specific areas in the brain that control renal responses and water and sodium intake. Among these areas are: organum vasculosum of the lamina terminalis (OVLT), subfornical organ (SFO), anteroventral third ventricl

11. The contracture produced by sodium removal in the non-pregnant rat myometrium.
1. Mechanical responses to Na removal were investigated in the circular and longitudinal muscles of the non-pregnant rat myometrium at 35 degrees C. In both muscles, reduction of the external Na concentration to less than 20 mM produced an initial acceleration of phasic contractions and a sustained tonic contracture. No difference was found with different Na

12. Recruitment order of motor units in man: significance of pre-existing state of facilitation 1
It has been shown in previous investigations that the recruitment order of motor units is different in tonic and in phasic voluntary activity. The significance of the pre-existing state of facilitation in the motoneurone pool for the recruitment of units is studied, using the phasic flexion reflex in the anterior tibial muscle as test reflex. It is shown tha
