ABSTRACT
Objective To observe the change ofbrain water content,levels of cAMP response element binding protein(CREB)and phosphorylated CREB(p-CREB) in the early stage of traumatic brain injury(TBI) and to investigate the effect of TBI and p-CREB on learning and memory.Methods Fifty-four male adult Wistar rats were randomized into the normal group(18 cases),control group(18 cases) and TBI group(18) according to the random number table method.The TBI model was built according to the modified Feeney method and previous experimental parameters.At 12 h after TBI,Western blot analysis were performed to measure the expressions of hippocampal tissue CREB and p-CREB,the Morris water maze test was used to detect the behavior of rats in each group and the wet-dry method was applied to test brain water content.Results The brain water content at 12 h after TBI in the TBI group was remarkably risen compared with the normal group and control group;the expression levels of hippocampal CREB and p-CREB at 12 h after TBI in the TBI group were significantly decreased compared with the normal group and control group,the latent stage was increased and the frequency searching the accuracy within 2 min was decreased.Conclusion Brain edema is obvious after TBI and the levels of CREB and p-CREB are decreased,which maybe one of the reasons for the impairment of learning and memory function after TBI.
