The results showed that the lesion of X-rays oncells displayed gradually attenuation with depth (or cellsurvival fraction displayed gradually increase with depth)while the lesion of heavy ions on cells followed Bragg curve(or cell survival fraction was inverse Bragg cueve).(2)Thedynamic change of micronuclei and cell survival inhepatoma SMMC-7721 irradiated by 25MeV/u〓 wasstudied.

采用HeLa、B16两种细胞分别研究了X-射线和重离子在水介质中入射的深度与相应细胞的存活率（1-失活率），结果表明：X-射线对细胞的损伤随深度而逐渐衰减（或细胞存活随深度逐渐增加），而重离子对细胞的损伤则为Bragg曲线（或细胞存活为倒Bragg曲线）。

In autumn,there were GTH1 cells and GTH2 cells in GTH cells. A large number of secretory granules in GTH1 cells were circumnuclear; In GTH; cells cytoplast,there were two types of secretory granules,small circle and large circle, in small number.Structure of STH cells had no obvious changes.

秋季，在GTH细胞中发现GTH_1和GTH_2两种细胞，GTH_1细胞具有大量的分泌颗粒，并呈围核分布，GTH_2细胞胞质中具有数量较少的小圆形分泌颗粒和大圆形颗粒；STH细胞的结构无明显变化。

Finally, because cnx-1 can further increase the germ cell death in ced-1 mutant, and the phenotype can be rescued by introducing cnx-1::gfp into the cnx-1; ced-1 double mutants, we suggest that cnx-1 acts in the engulfing cells other than the dying cells during the engulfment process of germline apoptosis.

除此之外，我们亦分析了cnx-1突变下ced-1(e1735)品种虫体之生殖母细胞的细胞死亡数量，发现cnx-1突变会额外地再提高ced-1突变下线虫生殖母细胞的死亡数量，且此现象可被外加入之cnx-1：：gfp 所消除；这两现象显示出cnx-1在线虫生殖母细胞的细胞尸体吞噬过程亦具有功能。

In this study, we utilized NCCmelan5 and NCCmelb4 melanoblast, two melanoblast cell lines which were previously used to investigate the treatment of vitiligo, to investigate the anti-apoptotic effects of LED (630nm), and ruled out others causes of repigmentation including proliferation, mitochondrial metabolism, melanin production, migration distances of MBs after irradiation, to formulate the theoretical basis LED's treatment of vitiligo.

在此研究中，我们使用研究白斑常用的NCCmelb4 and NCCmelan5两株黑色素母细胞珠来研究LED 光源对黑色素母细胞的抗凋亡的细胞保护功能，并且排除其对於细胞直接造成细胞增生，细胞移动，或黑色素增加的机转，希望为其治疗白斑的应用提供依据。

Then we transfected transitorily the recombinant of green fluorescent protein gene and middle molecular weight neurofilament cDNA into wide type N2a (N2a/wt) and N2a/tau40 to observe the effect of tau accumulation on GFP-NFM fusion protein transport in cellular processes in living cells. At last we used an apoptotic inducer, camptothecin (an inhibitor of topoisomerase-1) to treat N2a/wt and N2a/tau40 cell lines, and compared their apoptotic response.

主要结果如下：一、tau蛋白过度表达和聚积对细胞形态的影响：倒置显微镜下观察两种细胞的形态，发现N2a/wt细胞的突起多而长，而N2a/tau40细胞胞体变圆，突起明显缩短；免疫印迹结果显示转染了tau40的细胞内tau的免疫反应约增加14倍，免疫荧光结果显示N2a/tau40细胞胞体内呈现出较强的红色荧光，tau主要分布在核周和突起起始部分的胞质内，而N2a/wt细胞内的荧光很弱。

Then, pH-dependent behavior in both microspecies distribution and molecular electrical charge was described in detail.

其中运用药动学理论来定量描述和解析两抗菌药在大鼠体内两部位分布的动态学行为；使用体外培养的肺泡巨噬细胞单层模型，在依据其理化特性参数的基础上，来解释肺泡巨噬细胞对两抗菌药的吸收机理；并且得到以下初步结论

The results indicate that the thyroid gland of grey mullet is dispersedly distributed in the region of the arteria branchialis afferens of the first to the third pair of branchial arches. The monolayer follicle epithelial cells around a follicle were squamous shaped or cuboidal shaped, indicating an asynchrony of cellular activity in a follicle. The scale of the two shapes of cells differed significantly among developmental stages.

结果表明，鲻鱼甲状腺滤泡分散地分布在第1对至第3对鳃弓的入鳃动脉之间；构成同一滤泡的单层上皮细胞呈扁平形和立方形两种形态，反映出同一滤泡中上皮细胞生理活动的不同步，且发现不同发育时期的鲻鱼这两种形态细胞的比例有显著差异。

3By the analysis of linear correlation, coefficient correlation r is 0.999, coefficient of determination r~2 is 0.997,(F= 5862.949, P.001), we can think that there are linear correlation between the two adherences, the adherences are similar at different time, with the trend of increase by degress .

3应用直线相关分析考察两组细胞的贴壁率之间的关系，相关系数r=0.999，决定系数r~2=0.997，(F=5862.949，P＜0.001)，可以认为两贴壁率之间有直线相关关系，可以认为在不同的时间点两种细胞的贴壁率相似，并且有共同递增趋势。

Total RNAs from KAx-3 cells and AK127 cells(developed for 14h) were isolated. After the reverse transcription and PCR reaction, two distinct differential fragments were acquired., fragment A was from KAx-3 cells and fragment C was from AK127 cells. After retriving and reamplifying the differentially expressed fragments, white-blue plaqueselection, the fragments were purified. Northern blot proved that fragment A was from KAx-3 cells and fragment C was from AK127 cells. The results of sequencing and researching for NCBI database have been showed: part sequence of fragment A shows 91% similarity to the gene encoding DhkA, 92% similarity to the gene encoding DhkF, 91% similarity to the gene encoding STATc, 97% similarity to the homoeobox gene encoding protein. These genes play important part in controlling cell differentiation and cell proportion in Dictyostelium discoideum.

本研究通过提取盘基网柄菌发育14小时的野生型KAx-3细胞和突变型AK127细胞的总RNA，运用mRNA差异显示法分离出了两条明显的差异表达片段，其中片段A来自野生型KAX-3细胞，片段C来自突变型Ak127细胞；并通过凝胶回收差异片段、对差异片段进行再次PCR、蓝白斑筛选克隆、提取质粒、酶切电泳纯化差异片段；接着进行Northern杂交的结果表明，片段A只与野生型KAx-3细胞的总RNA有杂交信号，片段C只与突变型AK127细胞的总RNA有杂交信号，这就排除了差异片段假阳性的可能；最后通过测序，搜索NCBI BLAST数据库发现：片段A的小部分序列与编码组氨酸激酶DhkA基因中一段序列的相似性高达91%，与编码组氨酸激酶DhkF基因中的一段序列相似性高达92%，与编码STATc蛋白基因的一段序列相似性达91%，以及与编码同源框蛋白的基因中的一段序列相似性达97%，这些基因在盘基网柄菌细胞分化和细胞比例调控过程中起着相当重要的作用，这些数据进一步说明了突变细胞不能完成发育的原因。

Cell-cycle synchronization between the donor cell and recipient oocyte determines the embryo development in nuclear transfer. In the present study, we microinjected primary spermatocyte into the perivetelline space of oocyte. 37% pairs fused after electric stimuli and the resulting oocytes were culture for 2 h in MEM with or without CB.

在本研究中，我们将小鼠的初级精母细胞显微注入MI卵母细胞的透明带下，经直流电脉冲作用后有37％的初级精母细胞融入卵母细胞，然后将融合的卵母细胞分成两组在MEM和含有CB的MEM培养液中分别培养，2小时后将在CB培养液中培养的卵母细胞转入正常培养液中。

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。
