BACKGROUND During the last century, the management of blunt force trauma to the spleen has changed from observation and expectant management in the early part of the 1900s to mainly operative intervention, to the current practice of selective operative and nonoperative management. These issues were first addressed by the Eastern Association for the Surgery(More)

BACKGROUND During induced ischemia for cardiac surgery inefficient anaerobic energy mechanisms predominate. Sustaining aerobic metabolism with perfluorocarbon-supplemented blood cardioplegia theoretically could lead to improved postischemic recovery. Therefore we studied functional recovery after myocardial ischemia, comparing perflubron (C8F17Br)(More)
BACKGROUND The protective effects of myocardial preconditioning may occur by way of multiple mechanisms, with G-protein-mediated protein kinase C (PKC) translocation as a final common pathway. In this study we investigate the pharmacologic induction of preconditioning, by PKC translocation, using PKC agonists/antagonists to reveal its effects on contractile(More)
Retrograde cardioplegia (RCP) is often used for myocardial protection during coronary bypass grafting, but the regional effect of RCP in areas of evolving ischemia is unknown. We examined the functional and metabolic indices of regional myocardial preservation following acute coronary occlusion with evolving ischemia in a canine model. Following the(More)
