A number of plant and bacterial toxins act on ribosomes located in the cytosol.

许多天然的蛋白类毒素可以通过内吞途径进入细胞而抑制细胞的核糖体功能，从而导致细胞死亡。

After treated in 4% paraformaldehyde,we applied Hematoxylin-Eosin and Nissl staining to exhibit the structure of the retinae and ganglion cells respectively,and also we used immunohistochemical ABC method to display the distribution of GFAP-immunoreactive cells that were specifically classified as the astrocytes.

E 染色以显示视网膜结构，Nissl染色显示神经节细胞，免疫组织化学ABC法染色以显示星形胶质细胞特征性标志物胶质纤维酸性蛋白的阳性反应细胞的分布。

METHODS The killing effects of NDV-L on cancer cells and normal cell were observed by means of plaque assays, HA titer test and MTT test. The inducing effects of NDV-L on apoptosis were observed by means of Giemsa's dying test, phase contrast light microscopy, transmission electron microscope, DNA extraction, and flow cytometry.

通过噬斑形成单位、HA效价、MTT法等方法检测NDV -L对细胞的杀伤作用；通过Giemsa's染色法、倒置相差显微镜、透射电镜、DNA凝胶电泳、流式细胞仪检测NDV -L诱导肿瘤细胞凋亡的作用。

We used a single-cell model for human ventricular myocytes and also coupled-cell models composed of BP and NP cells.

我们用了一个人类心室肌细胞的单细胞模型和由BP和NP细胞组成的配对细胞模型。

This page provides some protocols about porcine brain tubulin, sea urchin sperm axonemes, rat liver cell cytosol and organelle fractions, organelle motility assay, tissue culture of PtK1 cells, basic protein chemistry and so on.

该网页提供了一些有关猪脑的微管蛋白、海胆的精子基因丝、大鼠肝脏细胞的细胞质和细胞器的级分、细胞器的运动性实验、PtK1细胞的组织培养、基本的蛋白化学等等方面的操作流程。

Microtubules play important roles in many essential cell functions including mitosis, intracellular transport, positioning of membrane-bounded organelles, and cell shape.

微管在细胞的许多过程中发挥着重要作用，如有丝分裂、胞内运输、膜围细胞器的定位以及细胞形态保持等等。

Observations underelectron microscopy showed that YSV destroyed the structure of chromatin,damaged cell organelles of tumor cells, and induced apoptosis and necrosis intumor cells.

超微结构研究显示，YSV(320μg／kg／d)诱导人肝癌BEL-7402细胞的染色质溶解、固缩，细胞器的普遍崩解，细胞出现凋亡和坏死。

Methods The 3-5 generation fibroblasts were inoculated in 24-well with rat-tail collagen. A denuded area was made when the 3 generation of the fibroblasts was influent into a monolayer. Cells were then exposed to the presence of various concentrations of viper venom, mitomycin C, and the cells migrated into the denuded area were counted evely 6 hours.

将培养的第3~5代人结膜下成纤维细胞接种于涂有鼠尾胶原的24孔板中，待细胞生长融合后在培养板上划线，造成无细胞的裸露区，分别加人不同浓度的蛇毒制剂、丝裂霉素C及二者的混合液，每6h观察记录移行至裸露区的细胞。

Nucleus changes in apoptotic cells were investigated by using Hoechst 33258 staining and photofluorography. Apoptotic rate was evaluated by propidium iodide staining and flow cytometer.

应用Hoechst 33258染色法观察凋亡细胞的形态学改变；PI染色流式细胞仪检测细胞凋亡率；Western印迹法检测Bcl-2蛋白的表达。

The histopathological changes were observed at the end of the experiment,the results showed that the significant increases in the thickness of mucosa、RAS and parietal cell number were present in TL(0.4 or 0.8 g/kg,ig)groups after prolonged effect of 0.015% ammonia water on gastric mucosa in rats,the mucosal epithelial cell and parietal cell lesions were significantly decreased in the TL group when compared with the model group.

结果表明，灌胃TL0.4及0.8 g/kg，可使粘膜及壁细胞的损伤、胃体部及胃窦部的炎细胞浸润症状、粘膜及PAS阳性层厚度、壁细胞计数等各指标较模型组有显著改善。

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。
