1. A influência do oxido nítrico na fisiopatologia da neuropatia glaucomatosa
Resumo O oxido nitrico (NO) é um fator relaxante derivado do endotélio e um potente vasodilatador que impacta em vários sistemas em todo o corpo. Estudos comprovam que o fluxo sanguíneo ocular basal é regulado pelo NO, sendo um importante regulador da homeostase, especialmente dentro dos tecidos uveais. A disfunção da produção de NO seria associado

2. Investigação dos efeitos toxicos e anti-hipertensivo de Arrabidaea chica Verlot (Bignoniaceae)
The species Arrabidaea chica (Bignoniaceae) is indicated to treatment of skin illnesses, renal stones, systemic arterial hypertension, as an antiinflammation and antianemia. In this paper it was avaliated the toxical effect of the extract of leaves of Arrabidaea chica Verlot (EAC), the chemical composition of EAC and the performance of EAC n the cardiovascul

3. INTERFERÊNCIA DE VASODILATADORES NA HIDRÓLISE DE NUCLEOTÍDEOS DA ADENINA EM PLAQUETAS DE PACIENTES HIPERTENSOS / INTERFERENCE OF VASODILATORS IN THE HYDROLYSIS OF ADENINE NUCLEOTIDE ON PLATELETS OF HYPERTENSIVE PATIENTS
The thrombogenic process that affects the hypertensive patient is associated with regulatory mechanisms present in the vascular endothelium. These mechanisms involve the release of a endothelium-derived relaxing factor, ectonucleotidases and calcium ions. Considering that vasodilators act both on blood pressure and on homeostasis, we evaluated the interferen

4. Biochemical and functional studies of twenty sildenafil analogues in human platelets and in the rabbit corpus cavernosum and aorta / Estudos funcionais e bioquimicos de vinte analogos do sildenafil em plaquetas humanas, corpo cavernoso e aorta de coelho
Sildenafil, a cGMP-specific phosphodiesterase-5 (PDE5) inhibitor, is used for the treatment of erectile dysfunction. In the search for a potent and selective PDE5 inhibitor, new sildenafil analogues (6a-v), characterized by the presence on the sulphonyl group in the 5 position of novel N-4-substituted piperazines or ethylenediamine moiety, were synthesized.

5. Efeito do relaxamento de Jacobson modificado, nas medidas de pressão arterial, freqüência cardíaca e freqüência respiratória em pacientes hansenianos.
The Hansen disease by its physiopatological and social aspects can promote the arising of stress and the development of cardiovascular diseases. The chronic stress causes high arterial systemic pressures. Dyspnea and tachycardia crisis can also occur in stressful situations. Objective To evaluate if the technique of Modified Jacobsons Progressive Muscular Re

6. Concentrações séricas de cálcio e ferro em jovens consumidores de tereré (Ilex Paraguariensis), Dourados-MS
The period of life comprehended within adolescence deserves especial concern due to the increase in physical growing and development; there is a major demand for nutrients from the organism. Calcium is absolutely important to the muscular, skeletal and endocrine development. Iron is necessary to the building of muscular mass, area in which major blood volume

7. Study of the activity of the leaves of Hipotensora Syzygium jambolanum D.C. (jambolan) / Estudo da Atividade Hipotensora das Folhas de Syzygium jambolanum D.C. (jambolão)
O presente trabalho foi desenvolvido com o objetivo de avaliar o efeito das folhas de Syzygium jambolanum D.C. (jambolão) na pressão arterial (PA) e na reatividade da musculatura lisa vascular e não-vascular de ratos normotensos. O extrato hidroalcóolico (EH; etanol 70%) foi obtido por maceração a partir das folhas secas de Syzygium jambolanum D.C. par

8. Duração do ato e do ciclo mastigatorio em individuos com disfunção craniomandibular
The purpose of this study was to assess the eletromyographic parameters of the masticatory act duration, in the muscles temporal anterior and masseter of the 46 subjects with craniomandibular disorders (CMD), corresponding to the period of time between the start and the final of muscle contration; the duration of the masticatory cycle, or the period between

9. Endogenous endothelium-derived relaxing factor opposes hypoxic pulmonary vasoconstriction and supports blood flow to hypoxic alveoli in anesthetized rabbits.
Agents that inhibit nitric oxide synthesis augment hypoxic pulmonary vasoconstriction. In an animal model of unilateral alveolar hypoxia, we investigated the hypothesis that endogenous endothelium-derived relaxing factor/nitric oxide opposes hypoxic pulmonary vasoconstriction and supports blood flow to hypoxic alveoli, resulting in a reduction in arterial ox

10. Endothelium-derived relaxing factor reduces platelet adhesion to bovine endothelial cells.
The adhesion of thrombin-stimulated human blood platelets to either the endothelial surface of intact bovine aorta or cultured bovine aortic endothelial cells was studied to determine the role of endothelium-derived relaxing factor in the regulation of platelet adhesion. Endothelial cells and platelets were pretreated with indomethacin to prevent the formati

11. Pressor effects of circulating endothelin are limited by its removal in the pulmonary circulation and by the release of prostacyclin and endothelium-derived relaxing factor.
Endothelin releases prostacyclin and thromboxane A2 from guinea pig or rat isolated lungs and endothelium-derived relaxing factor in the perfused mesentery of the rat. Endothelin is also substantially removed by the pulmonary circulation of the rat in vitro and in vivo and by guinea pig lungs in vitro. In the rat, the effects of endothelin on the blood press

12. Adaptation of myocardial blood flow to increased metabolic demand is not dependent on endothelial vasodilators in the rat heart.
OBJECTIVE: To investigate the role of endothelial vasodilating factors in adaptation of myocardial blood flow to increased metabolic demands. DESIGN: Alterations in the effects of endothelium dependent (acetylcholine) and independent (sodium nitroprusside) vasodilators and the beta 1 receptor agonist dobutamine were studied after inhibition of endothelium de
