There were abundant networks of NPY-Ir nerve fibers in the pial mater. It is expected that NPY released from these nerve fibers might be one source of Y〓-R ligands in SMCs, especially in the arteries under second branchs and in the arterioles.

在软脑膜中有密集的含NPY-Ir神经纤维网，所分泌的NPY可能是脑动脉（特别是第二级分支以下的小动脉和微动脉）平滑肌细胞中〓受体的配体来源之一。

The results indicated that the typical apoptosis was induced by PRRSV in lungs and uteri. The ultrastructural changes showed different characterizations at different stages of the infection. During the early stage from 8th h to day 3 postinfection,the apoptosis cells shrank,the cytoplasm concentrated,the chromatin condensed,the kernel disaggregated and the endoplasmic reticulum dilated. During the middle stage from day 5 to day 9 postinfection,the apoptosis cells evidently shrank,the cell membranes protu berated,the plastosome manifolded,and apoptosis bodies were found. During the last stage from day 10 upwards postinfection,the apoptosis bodies degenerated and disappeared,and no inflammation occurred. Few apoptosis cells were necrotic.

结果表明，PRRSV可诱导宿主肺和子宫发生典型的细胞凋亡，表现为细胞的超微形态结构随着病毒感染进程出现不同的特征性变化，早期（感染后第8 h至第3 d）凋亡细胞多表现为细胞体积缩小，细胞质密度增强，染色质浓缩，核仁解体，内质网扩张；中期（感染后第5 d至第9 d）凋亡细胞体积显著缩小，细胞膜突起，线粒体增多，有凋亡小体形成；晚期（感染后第10 d以后）凋亡细胞形态多表现为凋亡小体降解和消失，少数凋亡细胞在凋亡晚期表现为坏死细胞。

ObjectiveTo explore the significance of examinations of electrophysiology in the patients with cervical radicular spondylosis.

育龙网核心提示：探讨电生理检查对神经根型颈椎病的诊断意义。方法对97例神经根型颈椎病患者进行肌电图、运动神经传导速度、F波传导速度和体

These abnormal changes mainly occurred at two stages:(1) at meiotic prophase, almost half of Peiai 64S microsporocytes exhibited aberration, with sparse free ribosomes, underdeveloped mitochondria and many swollen endoplasmic reticula.

这些变化主要发生在两个阶段：（1）减数分裂前期，约半数的小孢子母细胞的胞质出现异常，游离核糖体稀少，并具有不发育线粒体和大量泡状内质网。

Electron micrograph showed us that hepatocytes were damaged seriously along with the prolonged NHBD time in A group. At the NHBD 120 and 150min in A group, hepatocytes showed numerous cytoplasmic vacuoles and lysosomes, round swollen mitochondria with clear matrix and rough endoplasmic reticula which was not in a stacked arrangement.

电镜发现，A组随着心跳停搏时间的延长，肝细胞的损伤逐渐加重，至120和150min时，肝细胞内可出现大量空泡和溶酶体，线粒体和粗面内质网结构也遭到破坏，但未出现明显的坏死和凋亡改变。

RESULTS: Neuronal degeneration and necrosis, mitochondria swelling, polyribosomes disaggregation from endoplasmic reticula, and golgiosomes dilation in the hippocampal CA1 area in the two FDP intervention groups were less severe compared with the control group.

结果：果糖干预组在神经元变性坏死、线粒体肿胀、内质网脱颗粒及高尔基体扩张等方面较FS组减轻，差异有显著性。

From the point of spatial distribution of mineral assemblage of a hydrothermal sulfide congeries, the upper part is dominated with chimney, and the lower part with massive sulfides followed by stockwork sulfides in the deep part. This seems to be a common feature of various hydrothermal active areas.

从矿物组合的空间分布来看，热液硫化物堆积体上部以烟囱体为主，下部以块状硫化物为主，深部以网脉状硫化物为主，这在不同热液活动区似乎具有普遍性。

Veined,stockwork and alteration-sheathed gold ores have been found in the area,belonging to four genetic types:the volcanic hydrothermal ores related to early—middle Carboniferous volcanism; subvolcanic hydrothermal ores related to intermediate—acidic porphyry intrusions; hydrothermal ores to the granitic intrusion and dynamo- hydrothermal ores related to regional dynamic metamorphism along the faults.

矿石类型有含金石英大脉型、石英网脉型和蚀变岩型。矿床成因类型有4种：一为火山热液型，其成因与区内早—中石炭世火山作用有关；二为潜火山热液型，与中酸性斑岩体侵位有关；三为岩浆热液型，与花岗质岩浆的侵位有关；四为动力变质热液型，沿断裂带分布于蚀变玄武岩中，系区域动力变质作用的产物。

At the age of 19 weeks, we have observed ciliated-mucous cells, some cells presented with mucous granules in the supranuclear cytoplasm and a ciliating border with short growing shafts, while the other cells presented with large mucous granules as well as compound cilia.

小粘液颗粒细胞呈柱状，胞浆顶部含有少量球形的粘液颗粒，细胞表面有短小的微绒毛，细胞核大呈椭圆形，胞浆电子密度高，胞浆下部有粗面内质网和线粒体，核上部有高尔基体。

All the ligands and complexes have been characterized with ~1H-NMR, MS and EA.X-Ray single crystal diffraction reveals that zirconium complex containing the tert-butyl substituted N_2O_2 ligand is an oxo- and hydroxyl-bridged dinuclear structure, which is possibly formed by partial hydrolysis of chlorides at one of the zirconium centers. A tetranuclear zirconium complex has been obtained and chacaterized, which is formed by complete hydrolysis of the chlorides at the zirconium centers.

通过研究配合物的单晶结构，我们发现叔丁基取代的不对称N_2O_2配体与ZrCl_4反应生成的锆配合物为氧桥和羟基桥连接的双核锆配合物，中间过程涉及单核锆配合物中氯原子部分水解，并得到氯原子部分水解的双核锆配合物和全部水(来源：8e6eAB67C论文网www.abclunwen.com)解的四核锆配合物的晶体结构，在晶体培养过程中发现双核锆配合物能够以手性自发拆分结晶析出。
