由细胞组成的

Discoloration of the tongue, commonly white, is due to deposits of epithelial debris, effete (or worn-out) bacteria, and food.

舌头的变色物质通常是白色的，由上皮细胞的沉淀物，死亡的细菌和食物组成。

EN is mechanical to alvine mucous membrane the protective screen of machinery of mucous membrane of protective action bowel of protective screen is main by mucous membrane of the mucus layer of surface of alvine mucous membrane, bowel epithelial reach its the composition such as close connection.

肠内营养对肠屏障功能的维护机理是多方面的，EN制剂的种类对小肠功能的改善功能也不相同。1 EN对肠黏膜机械屏障的保护功能肠黏膜机械屏障主要由肠黏膜表面的黏液层、肠黏膜上皮细胞及其紧密连接等组成。

TUNEL method was used to detected the apoptosis in the artery. Results:①The MSC cocultured with VSMC expressed smooth muscle a-actin, calponin and CD31, no cells positive for calponin and CD31 were detected in the control group; and a lot of filaments were observed in the co-cultured MSC by electron microscopy.②We gain dual-stable expression of AT2R gene medicated by doxycycline regulatable system of mesenchymal stem cells.

单独培养及VSMC条件培养液培养的MSC仅SM-α-actin表达阳性；(2)Dox-on系统由四个质粒组成：调节质粒pUHD17-1 hyg，荧光报告质粒pUHC 13-3，筛选质粒pSV2neo以及含目的基因AT2R的应答质粒pUHD10-3/AT2R，以上质粒经鉴定均与其背景资料相符合，可用于实现目的基因片段在靶细胞中可调控表达研究；(3)本实验通过连续两个回合的转染及抗生素压力筛选，经Dox诱导表达后获取出低背景、高诱导表达AT2R基因的克隆。

Amino acid similarities between goat and human were 87% and between gaot and mouse were 83%. Just like other members of FGFs superfamily, FGF5 protein also has a signal sequence ,at same time its protein has higly similar sequence about 120 Amino acid in central core sequence with other breed. Tissue specific expression of the FGF5 gene was also investigated in cashmere goat by RT-PCR analysis. The results showed that FGF5 gene was expressed in different time of the tested skin tissues, including anage and telegon.

结果如下：(1)本研究利用 RT-PCR 方法克隆了羊 FGF5 基因的 cDNA 序列，得到了 925bp的序列，并对该序列进行了分析，与成纤维细胞生长因子家族的成员一样也是由三个外显子组成，也具有一信号序列，成熟蛋白为 270 个氨基酸，经同源性比对得出大鼠与小鼠的 FGF5 氨基酸同源性最高为 97%，在与羊的蛋白质比较中大鼠与羊的同源性为 83%，小鼠与羊的同源性为 84%，人与羊的同源性最高，为 89%。

The fossil consists of a complete skull of an archaeocyte an extinct group of ancestors of modern cetaceans.

这些化石是由现代鲸类的祖先的原细胞的完整头骨组成。

Purpose:The kallikrein-kinin system is a complex multi-enzymatic system that has been implicated in the control of renal circulation, glomerular hemodynamics, and tubular function, which include kininogen, kallikrein and kinin.

目的：激肽系统(kinin-kallikrein system，KKS)是体内主要的降压系统之一，由激肽原、激肽释放酶(kallikrein ，KLK)和激肽组成，在调节血管壁的张力、细胞增殖及基质增生等方面具有重要作用。

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。
