查询词典 nucleus

The present morphological experiments revealed that Barrington's nucleus in the rabbit was also located in the dorsal pontine tegmentum, and that it sent projections fibers to the sacral parasympathetic nucleus and received afferent axons from the sacral spinal cord.

本实验研究表明，家兔Barrington's核亦位于脑桥被盖背外侧部，它发出纤维投射至骶髓副交感核，同时也接受来自骶髓的投射纤维，提示其脑桥排尿反射的构成可能与大鼠相似（论文4）。

But the latent period for reaching the platform above the water in Morris Water Maze of the Mn-exposed group was not different from that of control group. There was a significant increase in the areas,glial fibrillary acid proteinimmunoreactivity and the average proportional densities of GFAP-positive elements in nucleus caudate and accumbens in the high Mn-exposed group, and a significant reduction in the tyrosine hydroxylase immunoreactivity and average proportional densities of TH-positive elements in substantia nigra,ventral tegmentum area of midbrain and nucleus caudate in the high Mn-exposed group.

2高剂量染锰组尾状核和伏隔核的面积、胶质细胞纤维酸蛋白免疫反应强度及反应阳性产物的平均相对密度均较对照组显著升高；(3)高剂量组仔鼠黑质、中脑腹侧被盖区和尾状核的酷氨酸氢氧化酶免疫反应强度及其反应阳性产物的平均相对密度均比对照组明显下降。

It is found that there is an obvious transverse flow in the nucleus-nucleus reaction process.

发现两核碰撞过程中存在明显的横向流。

In microgametogenesis, callose deposits in tapetal cells and begins to accumulate around microspore nucleus at the early microspore stage, callose deposition around microspore nucleus continues through uninucleate microspere stage.

小孢子早期，绒毡层细胞中积累胼胝质类物质，小孢子核周围也开始沉积胼胝质，逐渐形成完整胼胝质壁；小胞子晚期，绒毡层细胞开始解体，药室内壁细胞开始加厚，其加厚的物质为胼胝质类物质。

Objective\ To study the neurotransmitters involved in the pathway from the abducens nucleus to the medial rectus subgroup of the oculomotor nucleus .

目的 研究大鼠展神经核到动眼神经核投射通路的神经递质。

The double labelling technique by combination of horseradish peroxidaseretrograde tracing with immunohistochemical staining for γ-amino-butyric acidwas used to observe the distribution of GABA-positive neurons in the abducens and vestibular nucleus,and its projection to oculomotor nucleus of rats.

用辣根过氧化物酶(horseradish peroxidase，HRP)逆行标记结合γ-氨基丁酸(γ-amino-butyric acid，GABA)的免疫组织化学双标技术观察大鼠的展神经核和前庭神经核内GABA阳性神经元的分布，以及其向动眼神经核的投射。

Neuroscience 2001;104:523-538.[12]Ma WL, Zhang WB, Zhang YF. Projection of the calbindin D-28k neurons receiving visceral nociceptive information from interstitial nucleus of the spinal trigeminal tract to nucleus of the solitary tract in the rat. Acta Anat Sin 2003;34:(in Chinese with English abstract).

表明CB同样存在于经INV至PB的伤害性信息传导径路内，且传递内脏伤害性信息的CB神经元多于传递躯体伤害性信息的神经元，提示含CB的神经元可能也参与了经INV中继的外周伤害性信息向PB的传递。

Precursors of sulfates and alkali halides prepared in co-deposition process were mixed homogenously, annealed at high temperature and then formed CoO and NiO fibers, XRD, XPS, Raman and SEM were used to characterized the samples, the growth of these fibers might be a special LS mechanism: soluble precursors in molten salt decomposed gradually to form initial crystal nucleus and succeeding particles adhered to these nucleus and grew anisotropically in the special high temperature fluent medium, the higher decomposition temperature and solubility of the precursor are two key factors in this method, which are in favor of a longer growth process and result in larger sizes of the final metal oxides crystals.

以共沉淀方法生成硫酸盐与碱金属卤化物融盐的均匀混合前驱物，在高温下退火制备出了CoO和NiO的晶须，以XRD和XPS等对成份进行了分析，SEM分析了形貌特征，研究了不同前驱物热分解特性，认为本方法是一种简单的LS生长机制：可溶性前驱物于融盐中热分解后逐渐析出成核，后续的粒子附着在核上，在融盐环境下沿一定方向作准一维生长，其产物形貌之不同源于硫酸盐的高分解温度和在融盐中的可溶性，导致晶体生长过程中成核过程与生长过程竞争的结果对一般前驱物结果的偏移。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
