The rats in the treatment group were peritoneally administered H7 (2mg/kg) at 0.5h and 12h after brain injury.

雄性SD大鼠60只，随机分为正常对照组、假手术组、脑损伤组和H7治疗组。

Objective: To observe the dynamic effects of treadmill pre-training on excitatory amino acid changes in striatum of rats with cerebral infarction and to explore the mechanism of pretraining protection to ischemic brain injury.

目的：动态观察预运动训练对大鼠脑梗死后纹状体处兴奋性氨基酸水平变化的影响，探讨预运动对缺血脑损伤的保护作用机制。

Considering the function of CCT, we speculate that CCT may play an important role in these function of ZNC PR, such as memory-enhancing activity, facilitate neurite elongation and prolongate cell ageing.

这与ZNCPR受体结合点的分布一致，结合CCT所具有的功能，我们推测CCT可能使ZNCPR易化记忆的获得和保持，并在脑损伤的修复、易化神经轴突的延长和细胞老化的延缓中起到一定的作用。

The decreased MSD and SRRmax, and the delayed MTT and TTP refect the disturbance of local cerebral microcirculation. This is because of the result of X-ray induced endovascular hyperplasia and the slowness of the local blood flow, and further support the theory of vascular injury in the injuried areas.

MSD、SRRmax的下降和MTT、TTP的延长，综合反映了放射性脑损伤局部微循环血流动力学的障碍，这是由于放射线引起血管内膜增生、血流缓慢的结果。

ObjectiveTo investigate whether grafting neural stem cells can ameliorate sensorimotor deficits following neonatal hypoxic-ischemic brain damage in rats.

目的研究神经干细胞移植对改善新生大鼠缺氧缺血性脑损伤后感觉运动障碍的作用。

The serum levels of TChE and SOD and CAT in hippocampus of mice in Cold group was also significantly higher than those in the Control group and Warm group(P 0.05或P 0.01),while the serum level of MDA in the Control group and Warm group were higher than that in the Cold group(P 0.05或P 0.01). Conclusion:(1)Long proper winter swimming could improve learning and memory abilities of mice.(2) Winter swimming could improve the ability of learning and memory by coordinate the content of acetylcholinesterase (3) This effect may be related to the decreased activity of TChE and the increased activity of anti-oxidatio.

1长期适量的冬泳运动可以促进小鼠学习记忆能力。2冬泳运动可以通过增加小鼠脑内海马组织中ACh的含量而影响TChE的活力。3冬泳运动促进学习记忆的机制可能是：3.1冬泳运动通过冷应激引起的神经内分泌系统的反应，来改变中枢神经系统的功能，使小鼠脑内乙酰胆碱的代谢增强、含量增加，从而促进学习记忆能力。3.2冬泳运动通过增强机体清除自由基的能力，来减轻脂质过氧化的程度，对小鼠的脑损伤起到保护作用，从而促进学习记忆能力。

Methods The MR findings of14patients with cerebral palsy caused by hypoxic-ischemic damage were studied retrospectively and correlated with clinical findings.All those patients underwent MRI.Cerebral cortex and subcortical white matter,deep white matter,basal regions and thalami,and ventricles and subarachnoid space were observed on T1WI and T2WI.

对14例缺氧缺血性脑损伤所致脑瘫患儿行MR检查，在T1WI及T2WI上对大脑皮层及皮层下白质、深部白质、基底节、丘脑、以及脑室和蛛网膜下腔等部位进行观察。

Due to the extent of the lesion, the existing ischemic brain damage and involvement of the torcular, no therapeutic options were available and the child died of irreversible cardiac failure.

由于该畸形导致的缺血性脑损伤的存在及中空区的累及，没有哪一种治疗方法是有效的，患者多死于不可逆性心脏功能衰竭。

The X-ray diffract was used to analyze the crystal structure of the composite. Results show that after the talc was treated with blend coupling agent, the crystal structure of talc changed, and effect Intercalation phenomenon.

通过X射线衍射分析可知，用混合偶联剂对滑石粉进行预处理后，滑石粉晶体结构发生改变，产生了插层现象，使PP／滑石粉复合材料为纳米复合材料。

An authentic Maui wedding might require the services of a 'kahu', which is a Hawaiian minister.

毛伊可能需要一个真实婚礼服务'kahu'，这是夏威夷部长。
