Abstracts of the 8th Meeting of the Italian Peripheral Nerve Study Group: 21

Erythropoietin (EPO) has neurotrophic and neuroprotective effects and its efficacy and safety has been demonstrated in patients with ischemic stroke. We investigated its efficacy in preventing and reversing established nerve disorders in streptozotocin (STZ) diabetes. After STZ injection (60 mg/kg/ip), EPO (5000 units/kg b.w. i.p. three times a week) was started in a group of rats and continued for five weeks (prevention schedule). In another group of diabetic rats, EPO was started six weeks after STZ, continued for five weeks (therapeutic schedule). Groups of non-diabetic control rats were similarly treated. Antidromic nerve conduction velocity (NCV) in the tail was assessed at five weeks for all groups and at 11 weeks for the therapeutic schedule. Compared to non-diabetic rats, NCV was 21% lower (P
