Intravenous BQ-123 and phosphoramidon reduce ventricular ectopic beats and myocardial infarct size in dogs submitted to coronary occlusion and reperfusion
Abstract The aim of this work was to investigate the influence of endothelin on myocardial ischemia and reperfusion in anaesthetized dogs. Animals were submitted to left thoracotomy and 120 min of left anterior descending coronary occlusion, followed by 180 min of reperfusion. Arterial blood pressure and electrocardiogram (ECG) were recorded in order to analyze heart rate (HR)–pressure product and production of ectopic beats. Infarcted areas were identified by a macroscopic staining method and infarct size was expressed as percentage of risk zone. To inhibit the effects of endothelin in a group of animals, we administered intravenously an endothelin synthesis inhibitor (phosphoramidon) and …
Flow cytometric analysis of peroxidative activity in granulocytes from coronary and peripheral blood in acute myocardial ischemia and reperfusion in dogs: Protective effect of methionine
BACKGROUND Methionine has shown protective effects in experimental models of myocardial infarction and is highly reactive to oxidative compounds produced by polymorphonuclear leukocytes (PMN), which in turn have been associated with myocardial damage. We have investigated the effect of methionine administration on spontaneous leukocyte peroxidative activity in myocardial ischemia and reperfusion. METHODS In anesthetized dogs, with coronary occlusion (90 min) and reperfusion (90 min), PMN activation was measured by flow cytometric determination of H(2)O(2) with dihydrorhodamine 123, and correlated to hemodynamic parameters and infarct presence. To assess a possible direct effect of methionin…
La elección de los modelos de costes de calidad: un análisis cualitativo
El actual contexto empresarial promueve que las organizaciones desarrollen una cultura orientada a la mejora de la calidad. En este sentido, consideramos que los distintos modelos de costes de calidad propuestos por la Contabilidad de Gestión pueden realizar importantes aportaciones en el proceso de mejora continua. La tesis pretende mostrar a las organizaciones las características de los distintos modelos de costes de calidad existentes de forma que éstas puedan seleccionarlos en función del mejor ajuste a sus parámetros específicos. Para ello, previamente presentamos un marco de trabajo que aborda como las variables contextuales afectan el Sistema de Información de Contabilidad de Gestión…
The Valencia Port Authority (VPA): environmental information in the annual report
In recent years, most companies are participating in the disclosing of information on the impact of their potential activities on the environment. In 2002, Spain developed its legislation on environmental information in annual reports. The port industry has a potential environmental and economic impact. In this context, it is important to know how it disclosure environmental information in the annual reports. The case of study shows the disclosure information characteristics of Valencia Port Authority (VPA) and the relationships with the environment. The results concluded that VPA has adapted its information not only the standards but as a mean of legitimation.
