The morphological changes of cultured bovine chromaffin cells were observed and the dopamine secreted was determined by HPLC to explore the feasibility of gene therapy with adrenal medulla cell transplantation.

为给肾上腺髓质细胞移植治疗帕金森病提供理论依据，观察正常体外培养和冷冻复苏后牛肾上腺嗜铬细胞的形态变化，并检测培养液中的多巴胺含量。

An electron microscopic study of resting cysts and their organelles in Paraurostyla weissei has revealed that:⑴The cyst wall is composed of four layers named from outside to inside:ectocyst,mesocyst,endocyst,and granular layer.The granular layer is delimited by the cell pellicle.Both the layer and pellicle contain a few vesicles.

为研究纤毛虫休眠状态下细胞的分化及其胞器的特征，本文以透射电镜术显示，魏氏拟尾柱虫休眠包囊中，颗粒层壁内有小泡，表膜位置也偶见小泡样结构，大部分线粒体以多个相互聚集在一起，自噬泡将线粒体等胞器包裹在内经历消化过程，细胞内膜系统十分发达。

Methods Rat spinal cord injury models were established by aneurysm clip compression, and nestin expression and proliferation of ependymal cells at different times were shown with pathological and immuno-histochemical staining.

应用动脉瘤夹压迫建立大鼠脊髓损伤模型，通过组织病理学及免疫组织化学方法检测不同时段室管膜细胞的反应性增生和神经外胚层多潜能细胞特异性抗原nestin的表达。

(1) Dobutamine can significantly increase 〓 exchange currents of ventricular myocytes in normal and hypertrophied rats, and the sensitivety to dobutamine in hypertrophied cells is decreased.

（1）多巴酚丁胺可显著增加正常大鼠和心肌肥厚大鼠心肌细胞的〓交换电流，但对肥厚心肌细胞的效应下降。

Multilocular renal cell carcinoma has aggregates of clear cells within the septae dividing cystic spaces.

多房性肾细胞癌的囊内有透明细胞的聚集，其间有分隔。

BACKGROUND: It is of significance to study the direct differentiation of human bone marrow mesenchymal stem cells into dopaminergic neurons and their functional characteristics for the treatment of neuropsychiatric disease such as Parkinson's disease with cell transplantation.

背景：研究人骨髓间充质干细胞定向分化为多巴胺神经元及分化后细胞的功能特征，对细胞移植治疗包括帕金森病在内的神经精神性疾病具有重要临床意义。

Today, it would be hard to find a multicellular organism that does not reproduce sexually (although some can reproduce both ways, like the Komodo dragon and its parthenogenic ability).

今天，我们很难找到一种多细胞机体不是有性繁殖的。当然，有些生物同时具备两种生殖方式，比如生长在印度尼西亚科莫多岛巨蜥就具备单性生殖能力。

The embryogenic cell first divided into multicellular proembryos,then globular embryoid,pearshaped embryoid,long embryoid,scutiform embryoid and mature embryoid.

胚性细胞继续分裂形成多细胞原胚，经球形胚、梨形胚、长形胚、子叶分化期到成熟胚，其发生的胚状体与单子叶合子胚形成具有相似的过程。

The results showed (1) The cells in upper and lower leaf epidermises of P. cyrtonema grew in a basically identical manner, that is, by their elongating and widening, and the elongating rate was higher than the widening rate.

结果表明：(1)多花黄精叶片的上下表皮细胞的发育方式基本一致，都是表皮细胞进行伸长生长和加宽生长，且伸长生长速度大于加宽生长速度。

During sexual differentiation, mitochondria and smooth endoplasmic reticulum in cells of testis also increase in quantity, but it is less than that in ovary, they disintegrate after sexual differentiation. The big grana always exsist in course of sexual differentiation, but small grana don\'t appear.

分化时精巢细胞的超微结构显示线粒体和内质网数量也有增加，但不如分化中卵巢细胞的数量多，分化后线粒体和内质网解体，在整个分化过程中大颗粒一直存在，无小颗粒出现。

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。
