The action of diaspirin cross-linked haemoglobin blood substitute on human arterial bypass conduits.
BACKGROUND Immediately available blood substitutes could transform medicine. In coronary artery surgery, vasoconstriction induced by some of these agents could have serious implications. We have examined some of the vasoactive effects of one of these blood substitute, diaspirin cross-linked haemoglobin (DCLHb), on isolated rings of human arterial conduits. METHODS Sections of human left inter...
متن کاملEffects of diaspirin cross-linked haemoglobin on post-traumatic cerebral perfusion pressure and blood flow in a rodent model of diffuse brain injury.
Diaspirin cross-linked haemoglobin (DCLHb) is a new oxygen carrying blood substitute with vasoactive properties. Vasoactive properties may be mediated via high affinity binding of nitric oxide by the haem moiety. Using a rodent model of head injury combined with ischaemia, we studied the effects of DCLHb on cerebral blood flow (CBF) and intracranial pressure (ICP). Twenty anaesthetized rats wer...
متن کاملAbsence of immunogenicity of diaspirin cross-linked hemoglobin in humans.
Diaspirin cross-linked hemoglobin (DCLHb) is an intramolecularly cross-linked hemoglobin-based oxygen carrier being developed as a therapy for acute blood loss. We report here the absence of immunogenicity of DCLHb in patients enrolled in phase II and III clinical trials of DCLHb. Two very sensitive immunoassays, an enzyme-linked immunosorbent assay (ELISA) and a Western blot assay, were develo...
متن کاملCoronary Artery Bypass Grafting with Arterial Conduits in the Elderly.
Although improved long-term outcomes obtained with the use of arterial grafts for coronary revascularization in comparison with the traditional association of a single arterial and saphenous vein grafts have been demonstrated in the overall population, the efficacy of this newer technique in the elderly is difficult to prove because their shorter life expectancy due to advanced heart disease, a...
متن کاملEffect of diaspirin cross-linked hemoglobin on normal and postischemic microcirculation of the rat pancreas.
Microcirculatory alterations with reduced nutritive supply to the pancreas could be the cause of hyperamylasemia, which occurs in some patients receiving the vasoactive oxygen carrier diaspirin cross-linked hemoglobin (DCLHb) in clinical studies. Therefore, the effects of DCLHb on rat pancreas microcirculation were evaluated. Anesthetized Sprague-Dawley rats received one of the following treatm...
