The exact mechanism might be that adriamycin destroyed SP and CGRP gangliocytes in trigeminal ganglions to decrease SP and CGRP synthesis and release therefore to inhibit the transmittion of nociceptin stimulation.

我们认为，将阿霉素直接注入神经干后，通过轴浆的逆行运输作用，阿霉素可到达三叉神经节，并选择性地破坏相应的节细胞，起到&化学切断&的作用，阻断中枢神经系统与三叉神经周围支之间的信息传递，从而达到治疗三叉神经痛的目的。

A.the gear ratio from rear roller to servomotor:It is a important parameter to ensure the basic yarn length and space and it must count exactly.

a。电机到后罗拉的齿数传动比：是纺纱中基纱纱支节长、节距准确性的一个重要参数，必须注意，准确计算。

The spiracles are bigger and more near dorsal line than all the others. Their trachea branches are taper and abundant and form short tracheoles. This gave the tufted form to the trachea, which appeared shrubby. The trachea branches that arranged in other segments gave them a tree-like look. They do not directly supply oxygen for tissues, but they suspend in the hemolymph and attach to the muscle of the heart, so that they can move in constant with the contraction of the heart muscle.②The 8th segment tracheal tufts have thinner cuticle and basal lamina than that of the other trachea, and have much pad cuticle, which is appropriate for them to move, and their basal lamina have small pores, which are favour of the permeation of gas.③Injecting the methylene blue into the larvae to label hemolymph, we observed that the hemolymph flow into the heart through the 8th segment tracheal tufts.④Normally these tracheal tufts have all kinds of hemocytes, which are abundant in the tufts. A large number of hemocytes released from tissues attach to the tufts by changing their structure when anoxic stress happen.

气管分支细短而丰富，形成气管簇，呈灌木丛状（其它各节气管则呈粗树干状分布），它不是直接给组织供氧，而是悬浮在血液中，与心肌相连接，随着心肌的收缩而不断运动；②气管簇的内膜及底膜都比其它各节的薄，且管壁内膜具有更多的适合运动的垫状表皮，底膜还有小孔结构，这有利于气体的通透；③向体内注射蓝色的亚甲基蓝标记血液发现，血液流动方向是经该气管簇后而流回心脏；④正常情况下，气管簇处有各种各样的血细胞聚集，当缺氧胁迫时有大量的血细胞从组织中释放出来，通过变形而紧贴气管簇，有利于气体的交换；⑤给体内注射无色的亚甲基蓝发现气管簇比其它各节更易变蓝，说明该处具有更高的获氧能力。

Flounder FoxD1 mRNA was over expressed in one cell of the two-cell stage zebrafish, MyoD expression in the somites on one side was reduced, but the expression in the adaxial cells was not affected; Myf5 expression in the presomitic mesoderm, adaxial cells and somites on one side was reduced.

在斑马鱼中过量表达FoxD1后，MyoD在一侧体节中的表达受到了严重抑制，而在近轴细胞中的表达未受影响，Myf5在体节前中胚层，近轴细胞，及体节中的表达都受到了抑制。

It has been certified that the maximum tensile and elongation of wheat straw without stem node is more than that of wheat straw with one stem node.

通过拉伸实验，测试了无茎节和1茎节麦秸秆在天然、浸海水、浸胶及浸胶后再浸海水4种工况下的极限拉力和极限延伸率。

Today, in the Greek and Russian orthodox churches, Christmas is celebrated 13 days after the 25th, which is also referred to as the Epiphany or Three Kings Day.

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。
