In this study we examined the anatomy of the infraclavicular region to assess the possibility of estimating brachial plexus depth before performing an infraclavicular block, by using readily identifiable landmarks such as the coracoid process and the clavicle.

在本研究中，通过简便的体表标志如喙突和锁骨，我们检查锁骨下区域的解剖来评估实施锁骨下阻滞前估计臂丛深度的可能性。

Agkistrodotoxin, a presynaptic neurotoxin and one of the two neurotoxins from the snake venom of Agkistrodon halys Pallas, has been further purified by DEAF -cellulose and CM-Sephadex column chromatography and vertical slab polyacrylamide gel electrophoresis.

本文在前文的基础上，改进了蝮蛇神经毒素的分离方法，纯化了蝮蛇毒中的两个神经毒素之一，突触前神经毒素Agkistrodotoxin，并对其生化特性进行了分析。

Recordings of the action potential of peroneal nerve trunk showed that the slow conduction fibers (＜1m/s) could be activated by the stimulation of SPN with a current intensity of 300μA, but not of DPN.

细胞内记录的资料显示，刺激PF或dPAG也引起几种不同的反应：①有兴奋性突触后电位和动作电位，并有兴奋后超极化现象；②在AP前有超极化现象；③只有EPSP和AP，无明显的兴奋后超极化。

I was too young for the responsibility I was given and I also had to play out of position as an out-and-out striker.

The entire changes is in conformity with pathological character of the CSM.

神经组 织学检查见到灰质前角神经元的变性、坏死、数量减少，以及侧索白质脱髓鞘变，排列紊乱，轴突断裂，病理变化符合CSM 的病理变化特征。

OBJECTIVE: To explore cervical adjacent zygapophyseal joint stress distribution following two level ADR and anterior cervical discectomy and fusion, so as to provide biomechanical reference for clinical application of two level ADR.

目的：观察轴向载荷对双节段颈椎人工椎间盘置换和前路椎间融合内固定对邻下位节段关节突关节内压力的影响，以期为双节段人工颈椎间盘置换的临床应用提供生物力学依据。

Chronic psychological stress can increase GC in Plasma and brain by HPAA. There are plentiful GR on Hippocam--pal cell membranes. It promote presynapitic membrane assoiling EAAs when GC combines with GR.

心理应激通过 HPAA 使血浆及脑组织中的 GC 升高，海马神经元细胞膜上存在丰富的 GR ， GC 与 GR 结合后，可促进神经元突触前膜释放兴奋性氨基酸。

The curves are compared which are obtained from three sets of damping oleo-hole with different constant section area under the same structure parameters and initial filling parameters.

经与3组不同直径常截面油孔在同样结构参数和初始填充参数下曲线的对比分析，证明采用变截面油孔缓冲器优化前起落架突伸性能的合理性。

Therefore, pDCs accumulated in spleens from HIV patients with high proviral loads, but they did not seem to be the main IFN- producers.

因此，浆细胞样树突状细胞在高前病毒载量的HIV阳性患者的脾脏内聚集，但并没有IFN等主要产物。
