Is endothelin-1 release during the early phase of reperfusion a mediator of myocardial reperfusion injury?
We propose that components of reperfusion injury involve ET-1 release which stimulates calcium overload and apoptosis. Intravenous ET-1 receptor blockade prior to reperfusion may be a protective adjunct to reperfusion therapy in acute myocardial infarction patients.
Cold ischemia augments allogeneic-mediated cell infiltration in rat kidney allografts. The earlier onset of acute rejection in 24-hour cold preserved allografts may be prevented by better preservation or treatment using tailored immunosuppression.
