查询词典 nerve cord

The lesion, the changes of activity of cholinesterase and acid phosphatase of motor neurons in lateral nucleus of spinal cord anterior horn, the function of axoplasm transportation and nerve conduction, the regeneration of axons and myelin sheath, and the recovery of sciatic nerve function were examined at 7, 14, 30 and 90 days intervals after operation, using Nissl and enzyme histochemistry staining, electrophysiological technique, hydrogen-peroxide oxidoreductase retrograde trace method, axon image analysis, and measurement of sciatic function index. The spinal cord anterior horn of injury side was compared to the correspondence region of spinal cord.

分别于术后7、14、30和90d应用酶组织化学方法、电生理方法、HRP （hydrogen-peroxide oxidoreductase）逆行示踪方法、轴突图象分析方法以及坐骨神经功能指数（sciatic nerve function index，SFI）测量等方法检测坐骨神经损伤后对应脊髓神经元的存活率、神经元胞体酶系变化、损伤神经在轴浆运输、电传导以及轴突、髓鞘再生等方面的恢复情况，探索外周神经损伤后OECs及几丁质对神经元的保护作用以及对新生神经功能恢复的作用，为外周神经损伤的治疗提供新的理论基础。

"Chordate:any of numerous animals belonging to the phylum Chordata, having at some stage of development a dorsal nerve cord, a notochord, and gill slits and including all vertebrate s and certain marine animals, such as the lancelets."

脊索动物：包括所有的脊椎动物以及如文昌鱼之类的海洋动物的脊索动物门的大量动物中的任一个，在某些生长阶段有背部神经索、背索及鳃裂。

The nerve cord of the shrimp is located at: 2 points

问题13：虾的神经索位於何处？

Methods Isolated toad sciatic nerve cord was prepared and the effects of stimulus parameters on action potential were investigated.

制备蟾蜍坐骨神经干标本，用不同的电刺激参数刺激坐骨神经干。

Objective To investigate the effects of electro-acupuncture on the proliferation of astrocytes and the expression of the endogenous nerve growth factor after spinal cord injury.

目的研究脊髓损伤后电针治疗对星形胶质细胞增生及其内源性神经生长因子（nerve growth factor，NGF）表达的影响。

Surrounded by water, front and back lost significance, and the inversion took place without any big shift of the nerve cord relative to other organs.

这样， 在与其他生理器官相联系的神经索没有进行大的移位的情况下，腹部与背部就发生了倒置。

The main characteristic features are the hollow dorsal nerve cord, the notochord, pharyngeal gill slits and tail.

主要的特色形状是中空的背脊中枢神经，脊索，咽鳃和尾巴。

In addition, the binding of BmK abT to Heliothis nerve cord synaptosomes was significantly enhanced by increasing the membrane potential and veratridine concentration and was inhibited by BmK IT2, but not by BmK AS or BmK I.

研究结果提示BmK abT 可以作为一个独特的新型钠通道调制剂探针用于深入研究电压门控钠通道的亚型、结构特征和功能特性。

Radiolabeled pharmacological binding assay showed: 1 BmK AS bound specifically to a single class of non-interacting binding sites on both rat brain and cockroach nerve cord synaptosomes with high affinity and low low capacity. The association of BmK AS with both synaptosomes was quick to reach equilibrium, but the dissociation seemed to be only partial. The specific binding of BmK AS was independent of membrane potential, and couldn't be modified by veratridine. Moreover, the binding of BmK AS could be inhibited by native BmK AS, BmK AS1, BmK IT2 and BmK IT on both synaptosomes, but not or partially inhibited by BmK Ⅰ and suggesting BmK AS type neurotoxins might bind to a distinct receptor site on mammal and insect sodium channels with a similar manner from β-scorpion toxins.

二。蝎毒素多肽配体与哺乳动物和昆虫靶离子通道受体的药理结合特性及其靶结合位点的研究：经放射性标记结合和竞争抑制实验表明：1）BmK AS在大鼠脑和蟑螂神经索突触体上有单一非协同性高亲和力低结合容量结合位点，能快速结合并达到平衡，但仅能部分解离，其结合不依赖于膜电位，也不受藜芦碱调节，天然的BmK AS，BmK AS-1，BmK IT2和BmK IT可抑制〓AS与两种突触体的特异结合，而BmK Ⅰ无或仅有部分抑制效应。

The spinal cord samples were hemisected and they were randomly divided into three groups: the control group, the olfactory ensheathing cell group, and the olfactory ensheathing cells and the nerve growth factor group.

目的：探讨大鼠嗅粘膜嗅鞘细胞（olfactory ensheathing cells， OECs）移植联合神经生长因子(nerve growth factor， NGF)修复脊髓急性损伤的可行性和疗效，并观察二者的协同作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
