pubmed:abstractText
Endothelin-1 is a vasoactive peptide produced by the vascular endothelium. It is one of the most potent endogenous vascular smooth muscle constrictors. Two subtypes of the endothelin receptor have been cloned and sequenced and denoted endothelin-A and endothelin-B. The aim of this study was to define the influence of cold ischemia on the production of endothelin-1 and on the endothelin receptors. Two different preservation techniques (cold storage only and cold storage with microperfusion with University of Wisconsin solution) also were compared. The study was performed in an in vitro bone perfusion model to isolate the vascular endothelium from blood components. The production of endothelin-1 by the bone vasculature was not altered after 24 hours of cold ischemia. No contractions were observed with S6c, a selective endothelin-B agonist, and this effect was not influenced by cold ischemia. The response mediated by the endothelin-A receptor was increased significantly, an effect that was not influenced by preservation with University of Wisconsin solution. This latter finding was the only significant alteration in the vascular function detected in the in vitro model after 24 hours of cold ischemia. With regard to the pharmacologic properties of endothelin-1, this mediated response could be implicated in the pathogenesis of vasospasm.
