神经组织

Recently, serching for an approriate artificial nerve alternative to autografting through tissue engineering technique has been hot spot.

近年来，利用组织工程技术研制一种可替代自体神经移植的人工神经是研究的热点。

The rats were divided into control group and experimental group . The Saline or autologous nucleus pulposus of coccygeal vertebral was injected to the epidurale cavum of rat, making the non-compressive model of experimental lumbar nucleus pulposus prolapse . The cauda equina nerve conduction velocity and the histologic changes were observed.

16只SD雄性大鼠随机分对照组和实验组，分别将生理盐水和大鼠自身尾椎髓核混悬液注射到腰椎硬膜外腔，对其马尾神经传导速度和神经根组织形态学进行观察。

Objective To study the effect of aging on the expression of nerve growth factor protein in the contusive or lacerated brain tissue after traumatic brain injury, and furthering explore the molecular biological mechanism for old patients having more severe neurological deficits.

目的 研究衰老对脑挫裂伤组织神经生长因子基因表达的影响，进一步探讨老年颅脑损伤病人神经功能缺失程度较重的分子生物学机制。

Six months later electrophysiological and histological examination were made to know the possibility and quality of regeneration.

术后6个月通过神经电生理和组织学检查了解神经再生的可能性及再生质量。

METHODS:The distribution changes of N CAM at flatfish muscle neuromuscular junction of rat in its embryon phase,14 day after birth,adulthood and 10,20 and 30 days after its L5 lumber nerve root injury were observed by immunohistochemistry and confocal laser scanning microscopy technologies.

采用免疫组织化学方法和激光共聚焦显微扫描技术，观察了大鼠胚胎期，出生后14d，成年期以及L5神经根受压后10，20，和30d，大鼠比目鱼肌神经肌肉接头部N-CAM的分布变化。

Part 1: Permeability of Exogenetic BDNF through placental barrier of pregnant rats and blood-brain barrier of fetus with transient uteroplacental ischemiaObjective To investigate the potential of BDNF to penetrate the placental barrier and get into the fetus and pass through the blood-brain barrier of fetus to play neuroprotective function in the condition of transient ischemia.

第一部分：外源性脑源性神经营养因子在宫内缺氧环境中对胎盘及胚鼠血脑屏障通透性的实验研究目的：探讨外源性脑源性神经营养因子在宫内缺氧环境下能否通过胎盘屏障进入胎鼠体内，再通过胎鼠血脑屏障进入胎鼠脑组织而发挥其生物功能。

Maher hit upon the beneficial effects of fisetin when she screened a collection of flavonoids, substances with anti-oxidant activities found in many plants, for their neuroprotective abilities in tissue culture models of neurodegenerative disease.

Maher在筛选一组类黄酮时偶然发现了非瑟酮的效用：很多植物里含有抗氧化物质，在细胞组织培养模式下，它能起到神经保护的作用，防止神经退化疾病。

Many studies reported suggest both neuronal precursor cells before innervation of target fields and the neurons of adult animal coexpress neurotrophic factors and their receptors, implying that autocrine and paracrine modes of NTFs exit. It has been observed that a number of neurotrophic factors and their receptors were expressed in cultured hippocampal cells and dorsal root ganglionic cells.

研究表明，无论是靶组织联系建立以前的神经元前体细胞，还是成年后的神经元，均有神经营养因子与其受体的共同表达，提示有神经营养因子自分泌和旁分泌存在的可能性。

Our result showed that P450scc expression was observed in hippocampus, habenular nucleus, neuron nucleus of thalamus and hypothalamus, and cerebral neocortex. The colocalization of P450scc and NeuN demonstrated that most of P450scc exist in neuron cell in these regions. In order to clarify the transcriptional regulation of CYP11A1 gene, established the transient SCC-iCre transgenic mice model by using R26R system to study the promoter activity of human CYP11A1 gene in the brain.

为了证明内生性P450scc在这些脑区的表现，本研究利用免疫组织染色分析，说明了在小鼠海马回结构，间脑内的上视丘疆核、视丘神经核、下视丘神经核，与新皮质等区域中皆可侦测到，且主要表现在神经细胞。

Animals in model group received L5 left hemilaminectomy and L5 dorsal root ganglion epineuriumet section and caudal vertebrae nucleus pulposus autograft,which was used to establish a modified rat model of non-compressed lumbar intervertebral disc herniation,while animals in Sham group received muscles autograft.50% paw withdraw threshold（50% PWT） of left hind limb was measured 1 day before surgery and on the 1st,3rd,7th,14th and 21st day after surgery in each group by "Up-Down" method to detect the change of the mechanical hyperalgsia.

模型组在左L5神经背根神经节应用自体髓核组织移植建立大鼠非压迫性腰椎间盘突出模型，假手术组应用自体肌肉移植。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
