Abstract

Noradrenaline levels in the superior cervical ganglion and sciatic nerve were significantly reduced in chronic streptozotocin-induced diabetes in rats. Sciatic nerve sheath in vitro biosynthesis of 6-keto prostaglandin F12 (6KPGF1a; the stable metabolite of prostacyclin) was significantly reduced but not in acute experimental diabetes Nerves with reduced 6KPGF1a had an excessive response to arachidonic acid stimulation We suggest that the reduced endogenous biosynthesis of prostacyclin is due to reduced substrate availability, possibly due to the reduced noradrenaline The implications of these findings on the pathogenesis of diabetic neuropathy are discussed. Neuropathy was found to involve all fibre populations studied (motor, sensory and sympathetic) and progressed with duration of diabetes.
