MethodsThe model of cerebral ischemia and anoxia in mice was established by decollation and ligating common bicarotid artery the effect of BVF on the survival time of the mice,and the time of catching their breath after mice decollated,and mouse brain capillary vessel permeability were observed.

方法采用小鼠断头、结扎双侧颈总动脉等脑缺血缺氧模型，观察苦菜总黄酮对脑缺血缺氧小鼠存活时间、断头小鼠喘息时间及脑毛细血管通透的影响；TBA法、NBT法测定小鼠脑缺血缺氧后脑组织MDA含量和SOD活性。

Results By using optical microscope, the neurocytes of hippocampus in experimental group were observed to denaturalize, tumefy, destroy and disappear.

点燃癫痫鼠海马区损伤越重，胶质细胞GFAP免疫反应性越强，通过检测GFAP可以推测星形胶质细胞与癫痫后脑损伤的程度。

The levels of asparate in 6 brain regions including striatum cerebral cortex,hippocampus,midbrain,cerebellum,diencephalon and olfactory bulb at 5,30 and 90 min after seizure were significantly decreased as compared with the control.Conclusion:The excitatory amino acid transmitter activity may play an important role in soman-induced seizures.

梭曼中毒后脑内谷氨酸和天门冬氨酸水平显著降低，递质耗竭是递质活动增加的征象，因此，谷氨酸和天门冬氨酸递质活动增加可能在梭曼中毒性惊厥的发生和维持中起重要作用。

Objective To determine the changes of vascular endothelial growth factor in diffuse brain injury.

目的 确定弥漫性脑损伤后脑内血管内皮生长因子的表达变化。

Objective To investigate the effect of thrombin on brain edema.

目的 探讨凝血酶与大鼠脑出血后脑水肿的关系。

Objective To investigate the influence of mannitol on brain edema after cerebral hemorrhage.

目的 探讨甘露醇对脑出血后脑水肿的影响。

Objective To compare the prognostic value of different electroencephalography grading standards of cerebral dysfunction after cerebrovascular diseases.

目的比较不同脑电图分级标准对脑血管疾病后脑功能损伤评价及预测预后的作用，旨在建立脑血管疾病的EEG评估标准。

In blastula embryos and 50% epiboly embryos, the zygotic pou2 transcript is also distributed in every blastomere cell. At the stage of 90% epiboly, expression of pou2 converges to the dorsal midline of embryos and locates in two waves of lateral neural plate and two transverse stripes in the brain region. In embryos at 100% epiboly, pou2 transcript is restricted in the neural plate and areas of presumptive midbrain amid himdbrain. From somite stage, gibel carp pou2 can not be detected any more, which is consistent with the RT-PCR result.

在高囊胚期和50%下包期，高度表达的合子转录本仍在所有的胚盘细胞中，但至90%下包期时，pou2的表达向胚胎背部的正中线汇聚，集中在神经板的两侧区域和脑部的两条横向条带在100%下包期时，pou2的表达集中在神经板的中间区域以及预期形成的中后脑区域至体节期时，转录本消失，这与RT-PCR结果高度一致。

Under the existence of special medium,the differentiation of neural stem cells from hindbrain is easier than that from forebrain .

在条件培养基存在的情况下，后脑组织分离的神经干细胞比前脑组织来源的更容易分化。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
