Abstract
Objective To explore the casepase-3 expression and role of casepase-3 in apoptosis following traumatic brain injury(TBI) in rat and the effect of dl-3-n-butylphthalide(NBP).Methods 120 male Wistar rats were randomly divided into 3 groups .According to Marmarou , severe closed brain injury was made .After that , immunohistochemical staining with Caspase-3 were performed of hippocampus CA1 region.TUNEL in situ was applied of the apoptosis cell in hippocampus CA 1 region.Double staining was to show the relation of apoptosis and Caspase -3.Results Caspase-3 in the trauma group began to increase at 3 h following injury , peaked at 3rd d and began to decline at 7 d. Caspase-3 in NBP treatment group was the same in each time , but in the peak , Caspase-3 was decreased in NBP treatment group compared with that in trauma group (P<0.01).At 3 h in trauma group , a little TUNEL positive cell appeared in hippocampus , peaked at 3rd d and began to decline at 7 d.TUNEL positive cell in NBP treatment group was the same in each time ,but in the peak , TUNEL positive cell was decreased in NBP treatment group compared with that in trauma group (P<0.05). The expression of casepase-3 was correlated with TUNEL positive cells ( P<0.01) .Conclusion NBP treatment in rats after TBI has certain neuroprotective effect , whose resistance roles in nerve cell apoptosis may be implemented by inhibiting excessive expressed caspase -3 caused by TBI .关键词
