Objective: Diabetes mellitus with 10% prevalence in human population leads to disorders of peripheral nervous system in many affected patients. It causes various polyneuropathies in which nerve conductionvelocity decreases. The aim of this study was to investigate the effect of cerebrolysinon the treatment of neural injuries resulted from hyperglycemia.
Method: Diabetes was induced in male rats weighing 250 ± 25 gr by intraperitoneal injection of 65 mg/kg streptozocin (STZ). Six weeks after STZ injection and appearance of neuropathy in diabetic rats, animals were divided into four groups: experimental, vehicle, diabetic and control. The experimental and vehicle groups received respectively single dose of 5 mg/kg day-1 cerebrolysinand saline intraperitoneally for two weeks. At the end, in order to find the efficacy of cerebrolysin, all groups underwent behavioral and electrophysiological tests as well as histological investigation.
Results: Metabolic parameters in different groups showed inefficacy of cerebrolysin in the treatment of metabolic disorders of diabetes. However, electrophysiological investigations showed efficacy of cerebrolysin in the treatment of diabetic neuropathy in rats. Moreover, investigation on morphologic structure of sciatic nerve was evident of the return of axon degenerative changes and myelin splitting in nerve fibers in cerebrolysin-received group. The results of behavioral studies showed increase in recovery in cerebrolysin group.
Conclusion: According to the results, treatment of diabetic neuropathy with daily injection of 5 mg/kg cerebrolysin for two weeks improves rats’ condition.
