Thy-1.1~+ OT-I CD8 T cells were adoptively transferred into Thy-1.2~+ host C57 mice treated with either isotype or PK136 Ab as mentioned above followed by injection i.v.withΔactA LM-OVA.On day 7 after infection,equal number of Thy-1.1~+ CD8 T effector cells from either hosts were sorted and adoptively transferred into second host mice(Thy-1.2) which were also on day 7 after infection and treated with isotype or PK136 Ab,respectively.

为进一步阐明NK细胞促进CD8Tm细胞的产生是作用于收缩期而不是扩增期，我们设计了如下的实验：将Thy-1.1~+ OT-I CD8 T细胞过继回输到经PK136抗体或对照抗体处理的C57小鼠体内并用ΔactA LM-OVA感染，7天后将两组小鼠脾脏中的Thy-1.1~+ CD8T细胞分离纯化后等量分别回输到同步感染的经PK136抗体或对照抗体处理的第二受体小鼠体内。

Thunberg Fritillary Bulb is one of the most popular Traditional Chinese herbs. Some trials in vivo and animals indicated that Peimine and Peiminine, extracted from Thunbery Fritillary Bulb, have the function of reversing MDR of two different kinds of mechanisms. They can improve the cytotoxic of ADR to cancer cells by 5～10 folds under concentration of 10% cancer cell growth inhibitory rate. Peimine and Peiminine not only feather typical character of modifier of MDR, but also differ from other moldifiers such as Calcium channel blocker, Cyclosporines in chemical structure, they belong to cevine groups alkaloid, a subgroup of C-Nor-D-homosteroid alkaloid.

浙贝母是临床常用中药，体外及动物试验证明，浙贝母中的有效活性成分贝母甲素和贝母乙素具有逆转肿瘤细胞MDR的作用，而且能逆转两种不同机制的多药耐药肿瘤细胞的耐药性，在无明显细胞毒剂量下，可使阿霉素对耐药肿瘤细胞的杀伤活性提高5-10倍，不但具备明确的多药耐药逆转剂的特征，而且在化学结构上属异甾类生物碱中的瑟文类生物碱，完全不同于钙离子拮抗剂、免疫抑制剂和其它现有的耐药逆转剂，具有作用靶点宽、化学结构独特的特点。

In TUNEL assay it can be observed that cystamine can reduce myocardial cell apoptosis . At the same time Western Blot analysis to prove cystamine can reduce cardiac cell apoptosis and Deth receptor and Mitochondria through theses two pathsway, NF-κB protein expression significantly increased furthermore, it promots cell survival, which can reduce cardiac hypertrophy,apoptosis.

在TUNEL assay中可以观察到胱胺可以减少心肌细胞的凋亡，同时我们也利用Western Blot证明胱胺可以减少心肌细胞的凋亡是透过Deth receptor和Mitochondria这两条路径，而这样子降低凋亡的现象很有可能与NF-kB这讯息传递的分子上升有关，因此胱胺确实具有保护心肌细胞的作用，可改善心肌细胞肥大、凋亡的情形。

In cross-sectioned root form 2 middle bark layer next Internal bark layer especial structure of regularly array; epidermis cell of stems and leaves have developed thickened epiderm, leaves epidermis covers hair, it formed developed vascular bundles.(4)Chromosomes of Agropyron cristatum is tetraploid .

根横切面上形成了在紧靠内皮层的两层中皮层细胞有规则整齐排列成两环的特殊结构；茎和叶表皮细胞均具有发达的角质层，叶表皮多密被毛，其形成了发达的维管束及维管束鞘。

After that , the comparison of the fertilizable competences of ICSI and IVF on cryopreservated oocytes was studied in this article , in order to establish an optimized method to improve the fertilizable competences of oocytes up to the level of embryos .

和胞浆内单精子注射两种方法对玻璃化冷冻卵母细胞的受精能力进行了比较研究，旨在建立能够进一步提高牛冷冻卵母细胞受精能力的改进方案，使卵母细胞冷冻技术上升到与胚胎冷冻同样成熟的水平。

He experiment results indicate that (1) The extract of Rubia Cordifolia L has the effects of anti-proliferation and inducing APO;(2) Whenadministrating with 5-fu, the extract of Rubia Cordifolia L obviously enhanced the effects of anti-proliferation and inducing APO of 5-fu;(3) The basement of molecular biology of the extract of Rubia Cordifolia L for inducing APO of MGC-803 cells is correlated with inhibiting the expression of bcl-2 of anti-apoptosis gene.

UNEL法与PCNA的免疫细胞化学法的结果：0.2、0.4、0.8、1.0mg/ml浓度的茜草提取物与2、4、8、16μg/ml浓度的5-Fu，分别诱导细胞凋亡和抑制细胞增殖，表现出浓度、时间依赖性关系，除个别浓度与个别时间之间无显著性差异（P＞0.05）外，不同浓度与不同作用时间之间均有显著性差异（P＜0.05或P＜0.01），并且两种药物联合使用时，MGC-803细胞的APO%显著提高，降低PCNA的阳性表达率（P＜0.05或P＜0.01）。

To this end,we used the Transwell system to select two highly invasive subcell lines SNU5-P3 and PAMC82-P3 from minimally invasive parent cells,and compared gene expression in paired cell lines wit...h high and low invasive potentials.38 genes were commonly upregulated in the two highly invasive subcell lines.

通过全基因组芯片比较SNU5-P3和PAMC82-P3与其亲本细胞的基因表达谱，获得了38个在两张芯片共同上调表达的差异基因，其中16/38(42%)已报道是与侵袭转移功能相关的基因。LOXL2是一个在两张芯片共同上调表达的基因，通过生物信息学分析和细胞表达谱分析，表明LOXL2可能是胃癌侵袭转移密切相关的功能基因。

One of these "daughter" cells is a new sperm producing cell, whilst the other cell further divides to form two new cells, each with only one member of each chromosome pair. As the unfertilised egg also contains only one member of each chromosome pair, the act of fertilisation re-institutes an embryo with 46 chromosomes.

之一，这些&女儿&细胞是一种新的精子产生细胞，而其他细胞的进一步分裂，形成两个新的细胞，每个只有一个成员，每一个染色体的配对，由於unfertilised鸡蛋也只包含一个成员，每一个染色体的配对，该法的受精重新研究所胚胎与46染色体。

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。
