Study of NT-1 in Promoting the Recovery Mechanism in MCAO Model / 现代医院

ABSTRACT

Objective To explore the study of NT-1 promote recovery mechanisms after cerebral ischemia.Methods 30 ICR mice were equally divided into NT-1 and BSA groups and respectively given NT-1 and BSA injection in the brain.The middle cerebral artery ischemia model was established with suture method.NRSS score and beam-walking test were used to exam the behavior performance after MCAO.Immnuohischemstry was used to evaluate the status of angiogenesis and apoptosis.Results Compared to the BSA group, NT-1 not only reduced the time on the beam-walking but the score of NRSS behavioristices.NT-1 also increased the number of vessels and reduced the number of apoptotic cells.Conclusion NT-1 cerebral injection can promote the recovery by increasing angiogenesis and inhibiting apoptosis.NT-1 is a promise target in the treatment of cerebral ischemia.
