During the differentiation, the simple morphology of OPCs progressively evolved to more complex forms with profuse outgrowth of elongated processes and extensive secondary branching.

OPCs能够在体外化学条件培养基内继续生长分化，胞体不断增大，细胞突起逐渐增多、增长并形成大量分支。

This year, his group showed that EDR1's role is to weaken a plant alarm signal called salicylic acid, a close chemical relative of aspirin that is produced by cells in diseased parts of the plant and orchestrates the plant's defences against the infection.

今年，他的小组显示，edr1的作用在于削弱一种称为水杨酸的植物预警信号，水杨酸是阿斯匹林的化学近亲，由植物罹病部位的细胞分泌，负责组织植物抵抗感染。

Immunohistochemistry results showed that the gray of PC12 cell cytoplasm appeared shallowing after HFS, suggesting that tyrosine hydroxylase activity decreased; The numbers of visible mitochondria in the cytoplasm, secretory granules, processes and synapse were decreased.

结果：相比对照组，HFS后PC12类神经细胞光镜下突起长度显著缩短，突起个数明显减少；酪氨酸羟化酶免疫组织化学结果显示HFS后PC12细胞胞质灰度降低，提示酪氨酸羟化酶代谢水平下降；电镜下可见胞质中的线粒体、分泌颗粒减少，突起和突触减少。

Methods: Immunohistochemicl method was used to detect the expression of Ki -67 in human villi and GTD.

采用免疫组织化学的方法，观察正常早期妊娠绒毛和妊娠滋养细胞疾病组织中Ki-67的表达。

We talced depigmentized skin of 60 patients respectively before and after treatment by Chinese herb, contrasting with the vulvae skin of 20 healthy persons and observed their different expressions of reproduction antigen Ki-67 and human primary haematopoietic cell antigen CD34 in different skin tissue by immunohistochemical method.

观察组60例患者于治疗前后分别取患处皮肤与20例正常人外阴部皮肤对照，采用免疫组织化学的方法，分别检测增殖性抗原Ki—67以及人原始造血细胞抗原CD34在不同皮肤组织中的表达并进行观察。

Instead of prescribing chemotherapies according to a doctor's best guess, they propose a genetic analysis to predict which type of chemotherapy would stand the greatest chance of zapping cancerous cells.

并不依赖于临床医生自己的臆断，而是通过分析患者的基因型来作出哪种化学制剂最有效地杀伤肿瘤细胞的推测。

Experiment 1, let rats acquire taste preference to quinine solution, and take account of β-EP-immunoreactive neurons in different nucleuses of hypothalamic areas, separately adopted taste preference learning training and immunohistochemistry; Experiment 2, Added banana essence into quinine solution to discuss the connection between flavor preference learning and the expression of β-EP; Experiment 3, To research endogenous opiate like substances contribute to the establishment of CTP and influence the behavior of taste preference by naloxone was i.p.

实验一，采用味觉嗜好学习训练和免疫组织化学方法，让大鼠获得对奎宁的味觉嗜好，计数了下丘脑不同核团内β-内啡肽免疫反应细胞数；实验二，向奎宁溶液中加入香蕉气味，探讨风味嗜好学习与下丘脑β-内啡肽表达的关系；实验三，腹腔内注射纳络酮，探讨内阿片肽对CTP建立及味觉嗜好行为表达的影响。

Fifiteen experiment animals were divided randomly into normal control group, 12h-post-trauma group and 36h-post-trauma group (5 each). Immunohistochemistry and image analysis techniques were used to measure the area, optic density value and integrated optic density value and integrated optic density value of Ngb immunoreactive products in primary somatosensory cortex (S1) and retrosplenial granular b cortex, which was located in the inner side and out side of traumatic brain injury cavity in coronal section of rat brain respectively.

采用自由落体硬膜外撞击方法建立脑外伤模型，15只实验动物分为正常对照组及脑损伤12、36h组，应用免疫组织化学和图像分析技术观察伤灶周围第一躯体感觉皮质区(S1)和压部后颗粒细胞b皮质区内Ngb免疫反应阳性信号面积、光密度和累积光密度的变化。

Methods Fifty white guinea pigs with normal hearing were randomly divided into the control group, ligustrazine group and traditional Chinese drug group. The alternations of hearing function were evaluated by the examination of auditory brainstem response. Some specimens were perfused by AgNO3 and observed the damage of bristle cell. And some were sent for immunohistochemistry to detect the expression of iNOS. Results Compared with the control group, the threshold of ABR in ligustrazine group and TCD group were tignificantly different.

将50只健康白色红目豚鼠随机分为对照组、顺铂组和中药组，各组动物均于用药前及停药后测试听觉脑干诱发电位，采用耳蜗铺片观察毛细胞损伤情况，应用免疫组织化学方法测定各组动物耳蜗内iNOS的表达情况。

The effects of copper sulphate, lead acetate, zinc sulphate, cadmium chloride and neckel chloride on growth and root tip cell divition of Cucumis sativus seedlings were studied respectively.

选用黄瓜籽苗为材料，硫酸铜，醋酸铅、硫酸锌、氯化镉和氯化镍为化学处理试剂，研究它们对黄瓜籽苗的生长及其根尖细胞有丝分裂的影响。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
