Abstract
Objective To investigate the effect of nerve growth factor (NGF) combined with rehabilitation training on the neurological behavior and expression of brain-derived neurotrophic factor (BDNF),pro apoptotic protein Bax in cerebral infarction rats.Methods Seventy two SD rats were randomly divided into control group,NGF group,rehabilitation training group and NGF combined with rehabilitation training group (combined treatment group).Each group was divided into 7 d,14 d,21 d after cerebral infarction subgroups.The cerebral infarction rat model was established with suture method.NGF group was intraperitoneally injected NGF 20 μg/(kg · d) ; rehabilitation training group was training by balance beam,rolling-bar and net screen 72 h after establish model; combined treatment group was given NGF and rehabilitation training.The neurological behavior scores were evaluated,the BDNF,Bax and their mRNA expression of brain tissue were detected with immunohistochemical staining and RT-PCR at the corresponding time points in each group respectively.Results Compared with control group,the neurological behavior scores in each time point subgroups of NGF group,rehabilitation training group and combined treatment group were improved ; and the expressions of BDNF and BDNF mRNA were significantly increased,the expressions of Bax and Bax mRNA were significantly decreased (all P < 0.05).Compared with combined treatment group,the neurological behavior scores in each time point subgroups of NGF group and rehabilitation training group were significantly increased,and the expressions BDNF and BDNF mRNA were significantly decreased,the expressions of Bax and Bax mRNA were significantly increased (all P < 0.05).Conclusion The NGF combined with rehabilitation training can up-regulate the expression of BDNF and down-regulate the expression of Bax,and significantly improve the nerve function recovery in rats with cerebral infarction.关键词
