The spatial learning and memory deficits of the rats are detected by MWM in early period post-BC(from 1 to 3 days after BC); 3. Pycnosis degeneration or necrosis neurons of the cerebral cortex, dorsal hippocampus, dentate fornix and brainstem reticular formation are identified in BC rats; 4. There are significantly changes in the number and activity of cholinergic neurons in the basal forebrain and brainstem reticular formation after BC; 5. The change of cerebral neurons and cholinergic neurons correlate with cognitive deficits in BC rats .

1、单摆式闭合性机械打击装置能成功建立脑震荡大鼠模型；2、脑震荡大鼠在MWM实验中出现早期空间认知行为障碍；3、脑震荡大鼠大脑皮质、背侧海马、齿状回和脑干网状结构出现程度不等的部分神经元固缩变性和不完全性坏死；4、脑震荡大鼠基底前脑、脑干网状结构ChAT活性表达有明显变化；5、脑震荡大鼠认知障碍与相关脑区神经元、胆碱能神经元的变化有关联。

Methods: A brain concussion was produced in rats using a simple pendulum device model. One control (n=12) and six experimental groups were used(n=12 in each group). The cerebral concussion groups were assigned to sacrifice times ranging from 1 day to 24days after injury.A Morris Water Maze memory paradigm was used to assess learning and memory function. Pycnosis degeneration or necrosis neurons in the locus cerebral cortex, dorsal hippocampus, dentate fornix and brainstem reticular formation were observed and counted after brain concussion. Cholinergic neurons in the basal forebrain and brainstem reticular formation were identified and quantitated using choline acetyltransferase.

应用自制单摆式闭合性机械打击装置建立脑震荡大鼠模型；成年SD大鼠随机分为1个对照组(n=12)和6个脑震荡组(即伤后1、2、4、8、16、24d，n=12)；应用Morris水迷宫(Morris Water Maze，MWM)实验评价大鼠的学习记忆功能；用光镜对大鼠的上述脑区的固缩变性坏死细胞进行观察和计数；用免疫组化方法检测基底前脑和脑干网状结构的胆碱乙酰转移酶(cholin acetyltransferase，ChAT)阳性细胞的表达。

There were no statistically differences between the 8th~ 14thday, the 15th - 21th day post-BC and the control group. During the rt~24tkday post-BC , pycnosis degeneration or necrosis neurons of the locus cerebral cortex, dorsal hippocampus, dentate fornix were significantly increased, then decreased gradually, but recovered to normal by the 24thday after BC, and especially in parietal cortex and piriform cortex the necrosis neurons were significantly increased than temporal cortex , and there were no statistically difference berween the left and the right side. Pycnosis degeneration or necrosis neurons in the brainstem reticular formation were markedly increased in the 4thday after BC, and there were no statistically difference among the other groups and the control group.

与对照组相比，BC后在大脑皮质、背侧海马和齿状回部位，固缩变性和不完全坏死细胞数先显著增加(P＜0.05)，然后逐渐减少，至24d基本恢复正常；顶叶、梨状皮质比颞叶皮质变性坏死细胞多，差异有高度显著性(P＜0.01)；大脑左侧比右侧变性坏死细胞稍少但差异无显著性；在BC后4d，脑桥核、斜方体核平面的脑干网状结构中固缩变性和不完全坏死细胞数明显增多(P＜0.05)，其它组间无显著性差异。
