1. Gender differences in microcirculation: Observation using the hamster cheek pouch
OBJECTIVES: Estrogen has been shown to play an important protective role in non-reproductive systems, such as the cardiovascular system. Our aim was to observe gender differences in vivo with regard to the increase in macromolecular permeability and leukocyte-endothelium interaction induced by ischemia/reperfusion as well as in microvascular reactivity to v

2. Implications of the hemodynamic optimization approach guided by right heart catheterization in patients with severe heart failure
Objective - To report the hemodynamic and functional responses obtained with clinical optimization guided by hemodynamic parameters in patients with severe and refractory heart failure. Methods - Invasive hemodynamic monitoring using right heart catheterization aimed to reach low filling pressures and peripheral resistance. Frequent adjustments of intravenou

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. Prevenção da nefrotoxicidade por contraste em pacientes oncológicos: comparação de hidratação com solução a base de cloreto de sódio e bicarbonato de sódio / Prevention of contrast-induced nephropathy in oncology patients. Hydration with 0.9% sodium chloride compared to sodium bicarbonate
The incidence of contrast nephropathy has increased simultaneously to the augment of the use of diagnostic and interventional imaging procedures. Unfortunately, a large number of physicians do not know its existence and even when so do, sometimes do not do not know the risk factors associated to its development. The incidence of contrast nephropathy in the g

5. Relaxation of rabbit corpus cavernosum smooth muscle and aortic vascular endothelium induced by new nitric oxide donor substances of the nitrosyl-ruthenium complex
INTRODUCTION: Endothelial dysfunction characterized by endogenous nitric oxide (NO) deficiency made 56% of patients affected with erectile dysfunction decline treatment with PDE-5 inhibitors. New forms of treatment are currently being developed for this group of patients. MATERIALS AND METHODS: The study compared the effect of sodium nitroprusside (SNP) and

6. Bradykinin or acetylcholine as vasodilators to test endothelial venous function in healthy subjects
INTRODUCTION: The evaluation of endothelial function has been performed in the arterial bed, but recently evaluation within the venous system has also been explored. Endothelial function studies employ different drugs that act as endothelium-dependent vasodilatory response inductors. OBJECTIVES: The aim of this study is to compare the endothelium-dependent v

7. IdentificaÃÃo dos mecanismos envolvidos no relaxamento da musculatura lisa cavernosa e da aorta de coelho, induzido por doadores de Ãxido nÃtrico do complexo nitrosil-rutÃnio / Identification of the involved mechanisms in the relaxation of the cavernous smooth musculatura and aorta of rabbit, induced for nitric oxide givers of the nitrosil-rutÃnio complex
Endothelial dysfunction makes 56% of patients with erectile dysfunction decline treatment with PDE-5 inhibitors. New forms of treatment are necessary for this group of patients. The present study evaluates the relaxation in vitro induced in rabbit corpus cavernosum smooth muscle and aortic rings by sodium nitroprusside (SNP) and by two new NO-donor substance

8. Identificação e caracterização funcional de atividade apirásica nas salivas de triatomíneos vetores da Doença de Chagas
Blood-feeding arthropods are able to constraints barriers imposed by host defenses, due to the presence of a wide range of antihemostatic factors in their saliva, including vasodilators, antiplatelet factors and anticoagulant. The main Chagas disease transmission mechanism is contamination of a host by faeces from triatominae infected. Triatoma infestans Klu

9. Effects of high glucose concentrations on the endothelial function of the renal microcirculation of rabbits
OBJECTIVE: To assess the acute effects of high glucose concentrations on vascular reactivity in the isolated non diabetic rabbit kidney. METHODS: Rabbits were anaesthetized for isolation of the kidneys. Renal arteries and veins were cannulated for perfusion with Krebs-Henselleit solution and measurement of perfusion pressure. After 3 hours of perfusion with

12. Do cardiologists at a university hospital adopt the guidelines for the treatment of heart failure?
OBJECTIVE: To verify whether the guidelines for the treatment of heart failure have been adopted at a university hospital. The guidelines recommend the following: use of angiotensin-converting enzyme inhibitors for all patients with systolic ventricular dysfunction, use of digitalis and diuretics for symptomatic patients, use of beta-blockers for patients in
