阻断

Chloride channels have been identified in vasucular smooth muscle cells. These channels have been shown to be involved in myogenic tone regulation and neuromuscular transmission in various vascular beds. However, whether the chloride channels are responsible for the formation of excitatory junction potentials of the smooth muscle cells in the spiral modiolar artery remains elucidated.

许多研究已证实，血管平滑肌细胞膜上存在氯离子通道，进一步研究发现氯离子通道不仅参与调节平滑肌细胞的肌原性紧张，而且参与了许多种类血管床的神经平滑肌细胞之间的信息传递，但Cl-通道及氯离子通道阻断剂对耳蜗螺旋动脉细胞兴奋性接头电位(excitatory junction potential，EJP)是否有影响，目前还不清楚。

In the present study, the effects of chloride channels blockers,(Niflumic acid,NFA;IAA-94;DIDS) on EJP were explored in guinea pigs, using intracellular recording techniques on acute isolated spiral modiolar artery.

本实验运用细胞内微电极记录技术，在豚鼠耳蜗螺旋动脉(spiral modiolar artery， SMA)离体标本上，研究氯通道阻断剂(Niflumic acid， NFA； IAA-94； DIDS )对去甲肾上腺素引起SMA平滑肌细胞的反应和平滑肌细胞EJP的影响。

We speculate that antisense p42 may affect the separation of replicated centrosome, thus results in the formation of monopolar spindle, and affact the happening of the cytokinesis of HAP42 cell.

推测反义p42可能特异地延迟或阻断联系中心体间某些蛋白的水解，影响了细胞已复制的中心粒的分离，形成了单极纺锤体。

Results Shuichangpu increased the resting tnesion of longitudinal and cicular muscule of fundus and bodys.Atropine and hexamethonium inhibited the effect of shuichangpu partially.

结果 水菖蒲水煎液增高胃底和胃体纵、环行肌条的张力，阿托品和六烃季胺部分阻断水菖蒲增高胃底纵、环行肌及胃体环行肌张力的作用。

Objective:To evaluate the value of uterine arterial blocking before myomectomy in laparoscopic procedures.

目的：探讨腹腔镜下子宫动脉阻断后行肌瘤剥除治疗子宫肌瘤的临床效果及可行性。

GA antagonized SMA constriction induced by myricetin. The antagonizing effect on myricetin in shock 1, 2 and 3 hours groups was more obvious than that in the other groups. CONCLUSION :At the early stage after hemorrhagic shock, the endothelium-dependent and independent vascular contractile response show a compensatory increase.

SMA血管环对杨梅黄酮的反应主要表现为：休克0、0.5、1和2 h组明显高于正常对照组，于休克2 h达最高点；休克3 h和4 h组明显低于正常对照组，运用18α-GA阻断MEGJ后，各组血管环的收缩反应性较18α-GA作用前明显下降，其中以休克1、2和3 h组下降幅度明显大于其他组。

According to the condition of renal trauma, partial nephrectomy, nephrorrhaphy, nephroangistomy were made. The longest time of warm ischemia of kidney was 102 minutes, the shortest time of that was 28 minutes, with the average of 53 minutes.

术中采用静脉注射肌苷后，常温下阻断肾血流，根据肾破裂情况，分别采用肾部分切除、分层对位缝合、血管修补等修复手术。

In conclusion, postinjection alcohol neurolysis pain can be treated with steroid injection, which may increase the efficacy of NCPB.

总结来说，酒精神经烧灼术后疼痛可以用类固醇注射来治疗，并且可能增加腹腔神经丛阻断的效果。

March 2, 2004 Neurolytic celiac plexus block reduces pain for patients with pancreatic cancer but does not improve quality of life or survival, according to the results of a randomized trial published in the March 3 issue of The Journal of the American Medical Association .

March 2， 2004 -根据一项发表於3月3日美国医学协会期刊的随机试验结果显示，腹腔神经丛阻断术能减轻胰脏癌病患的疼痛，但是无法改善生活质量或存活数。

Activation of Fasl and Caspase3 may be related to cells apoptosis in the injured spinal cord. Early application of rhEPO could improve the neuromotor function. The protection is partially due to the reduction of neural cell apoptosis.

结论］早期应用外源性EPO对脊髓不完全损伤具有保护作用，可明显改善神经运动功能恢复情况，此种保护作用可能与EPO能够阻断Caspase3、fasfasl死亡蛋白途径的神经细胞凋亡有关。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
