ABSTRACT
Objective To investigate the protective effects of Cerebroprotein Hydrolysate for injection (I) on vascular dementia (VaD) in rats.Method The permanent bilateral common carotid artery ligation method was used to prepare a VaD rat model.Suture of rats was performed after separation of the common carotid artery in Sham group.The model rats were randomly divided into model group,Cerebroprotein Hydrolysate Injection (Cerebrolysin,10 mg/kg,positive drug group),Cerebroprotein Hydrolysate for injection (I) high,medium and low dose (20,10 and 5 mg/kg) groups.Rats were treated with relative drug by tail iv injection once daily for two weeks,and rats in Sham group were given equal volume of saline.The learning and memory abilities were evaluated by Y maze and step-through tests.Besides,the levels of insulin-like growth factor-I (IGF-1) in VaD rat serum were determined by ELISA method.Results Compared with model group,Cerebroprotein Hydrolysate for injection (I) significantly increased the correct number in Y maze test,reduced the step-through latency time,and elevated serum IGF-1 level in VaD rats.The protective effects of Cerebroprotein Hydrolysate for injection (I) in VaD rats were equivalent to the same dose of Cerebrolysin.Conclusion Cerebroprotein Hydrolysate for injection (I) could significantly improve the learning and memory abilities of VaD rats,presumably through a mechanism of elevating IGF-1 level,which promotes the repairment and growth of neurons.
