Ca2+concentration in singular Cu treatment group was usually higher than that in composite group by using localization of Ca2+ antimonite precipitation technique,.And distributing of Ca2+ in composite group.has no obvious difference from control group.

运用焦锑酸钾沉淀法发现，单一Cu处理的慈姑根细胞质中的C扩+浓度要比复合处理的普遍高，而复合处理组根细胞内的c扩十分布与对照无显著的差异，只是有较少的细胞中的焦锑酸钙沉淀颗粒比对照多。

Spermatogenesis is a complex process of cell division and differentiation resulting in a series of molecular and morphological changes in male germ cells.

精子发生是一个多阶段，多步骤持续的细胞分裂和分化过程，它受到性染色体和常染色体上一系列基因的调控。

利用兔后腿软组织损伤、海水浸泡模型，分别于损伤后浸泡于海水中2小时，浸泡后分别进行各种低渗盐水冲洗，分别于干预处理后1h、3h、6h、8h、12h，在损伤周围0.5cm范围内的肌肉组织中取材，0.5cm3损伤组织用4%福尔马林固定，HE染色，光镜下观察损伤组织的细胞浸润情况，用免疫组化法检测受伤肌肉组织凋亡相关基因Caspase3表达情况；1mm3损伤组织用1%戊二醛一%多聚甲醛混合固定液(pH7.4 ) 4℃固定，电镜观察其细胞凋亡及细胞膜、线粒体等结构的变化；生化检测Na+，K+-ATPase活性，了解其组间的差别。

Methods:Cardiac muscle of twoday neonate rattus was digested repeatedly by 0.0625% trypsin.The cardiocytes were collected in DMEM medium,which contains 10% fetal bovine serum.Myocardial cells were isolated with the technique of differential anchoring velocity with 90 min and were pured by Brdu.The cardiocytes were placed into CO2 incubator to incubate seven days after their purification.

应用0.0625%的胰蛋白酶重复消化出生第2 d乳鼠的心肌组织多次，收集的细胞用含10%胎牛血清的DMEM培养基中和，用差速贴壁分离法分离，在以溴脱氧尿嘧啶纯化心肌细胞后置CO2培养箱孵育7 d。

The immune system reacts powerfully to a surprising variety of the patient's molecules, ranging from targets exposed at the surface of cells to some inside of cells to even some within a further sequestering chamber, the cell nucleus.

狼疮患者的免疫系统会对体内许多分子产生强烈反应，种类多到令人惊讶，从暴露在细胞表面的分子到细胞内的分子，甚至是包在细胞核内的分子。

In the period of 8 to 16 weeks after operation,new bone was formed continuously, artificial bone gradually reconstructed to mature lamellar bone,bone trabeculae and medullary cavity,etc. Conclusion The preparation of CPC is simple.

结果 CPC植入后4周有新生软骨形成及未成熟的骨组织，可见大量的软骨细胞、成骨细胞、胶原组织及较多的小血管。8～16周新骨继续生成，人工骨逐渐改建为成熟的板层骨、骨小梁和髓腔结构。

Results There existed new cartilage and new immature bone tissue in the bone substitute in 4 weeks after operation, as well as mass of cartilageous cells,osteoblasts, collagen tissue and more small vessels were seen. In the period of 8 to 16 weeks after operation,new bone was formed continuously, artificial bone gradually reconstructed to mature lamellar bone,bone trabeculae and medullary cavity,etc.

Meanwhile, more ligands were tethered onto the comb-like PEG modified surface with a great amount of reactive end groups, which increased cell proliferation. The glycocalyx mimicking surface designed with comb-shaped PEG end-tethered by RGD peptide was proved to present non-specific resistance and excellent cyto-compatibility simultaneously.

此外， CPEG比LPEG具有更多的活性反应基团，用PEG末端活性的醛基固定整合素配体多肽片段RGD，可有效地诱导材料表面的内皮细胞化，改善材料的细胞相容性。

Udensis' genetic variation, its historical causes and dispersal, and references for the explanation of China's geological changes and post-Pleistocene geographical dispersal of plants.

由于七筋菇植物不同细胞型共存，两种细胞型的分布区相邻或重叠，为我们探讨七筋菇种群的遗传结构和遗传分化，多倍体的起源、扩散和演化，及其迁移路线提供了理想的天然研究场所。

However, it remains to be determined if virion attachment to target cells is sufficient to induce cell death, or if apoptosis is triggered directly or indirectly by one or more virion-associated proteins.

但是，是毒吸附细胞表面诱导凋亡的发生还是病毒的一个或多个结构蛋白诱导细胞凋亡的发生还有进一步的研究。

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。
