Increased oxidative stress has been causally linked to diabetic neurovascular complications, which are attenuated by antioxidants. There are several possible sources of reactive oxygen species in diabetes. Our aim was to assess the contribution of free radicals, produced by transition metal catalysed reactions, to early neuropathic changes. To this end, we examined, firstly, the effects of an extracellular high molecular weight chelator, hydroxyethyl starch-deferoxamine, which is expected to be confined to vascular space, on nerve perfusion and conduction deficits in diabetic rats and, secondly, the action of a single chelator dose.
