It is suggested that the algae symbiot can affect host organellar function,quantity and location, stimulate the food uptake and digestive activity, restrain the functional activity of the organelle, change the gene expression and cause the change of genome structiure in the P. bursaria-chlorellae system.

据结果推测，纤毛虫中的藻类共生体可影响宿主细胞中胞器的功能、数量和分布，可影响细胞核核仁的数量和分布；可影响宿主细胞的形态、生长、抗氧化能力及胞质糖含量；可影响宿主细胞的食物摄取及相关胞器的消化活性，抑制宿主胞器的功能活动；并可改变宿主细胞基因的表达，导致细胞基因组结构的变化。

According to anther abortion characteristics and hormone functions, it was suggested that IAA, GA3 and ZR deficiency might be associated respectively with the inhibition of starch grain accumulation, pollen mother cell and tapetal cell expansion and tetrad formtion, and that abortion and even death of pollen mother cells and tapetal cells in sterile anther might be accelerated by high ABA accumulation.

根据内源激素的功能推测，不育花药IAA含量过低使花药淀粉积累受阻，GA_3含量不足影响花粉母细胞和绒毡层细胞的膨大，过低的ZR含量使花粉母细胞不能分裂形成四分体，过高的ABA含量促进花粉母细胞退化和死亡。

RESULTS: APC promoter 1A was methylated in NCI-H460 cells, and unmethylated in NCI-H446 and SPC-A1 cells. Hypermethylation was detected in all 5 CpG islands (687, 707, 714, 719, 726) of APC promoter 1A in NCI-H460 cells. The expression of APC in NCI-H460 cells was decreased by 26.04% of that in NCI-H446 cells and by 32.36% of that in SPCA1 cells. After treatment of 1, 5, 10, 15μmol/L 5-aza-dC, the expression of APC promoter 1A in NCI-H460 cells was enhanced by 4.59, 5.78, 9.58, 5.98 folds, respectively.

结果：SPC-A1和NCI-H446细胞APC甲基化阴性，NCI-H460细胞APC甲基化阳性；甲基化芯片检测Ncl-H460细胞在APC启动子1A 5个CpG位点均存在甲基化(687、707、714、719、726)，SPC-A1和NCI-H446甲基化阴性，荧光定量结果NCI-H460的APC转录较SPC-A1和NCI-H446有明显的下降，仅为二者平均的30.04%；经5-aza-dC脱甲基化作用后，NCI-H460细胞的APC表达增加了约5~10倍，其中10μmol/L浓度作用下，APC表达增加最多。

In this study, we found that the mechanism for LED (630nm) repigmentation in vitiliginous skin is not through direct stimulation of melanin synthesis, proliferation, nor cellular migration. On the contrary, LED puts healthy MBs to arrest and prevents death of un-healthy cells through a cyto-protective mechanism with regulation of the mitochondria pathway of apoptosis.

我们发现红光二极体照光治疗白斑的机制，并非在於直接促进黑色素增加，使细胞增生，或是使细胞移动能力增加，反而是使黑色素母细胞一些生理功能停歇，经由调节经粒腺体的凋亡机转，来预防黑色素母细胞的死亡，进而达到保护的作用。

Objevtive: To investigate the effect of effective parts of Zingiber officinal on the adhesion of ECV-304 cells with monocytes cultivated in vitro and on the expression of monocyte chemotactic protein-1 (MCP-1) and adhesion molecules.

中文摘要：目的：研究鲜姜有效部位对离体培养的血管内皮细胞与单核细胞的黏附力及对单核细胞趋化蛋白和黏附分子表达的影响，探讨其保护血管内皮细胞的作用机制。

Culture and immunohistochemistry of Schwann cells Schwann cells that are derived from sciatic nerve of Sprague-Dauley rats are successfully isolated, cultured. The Schwann cells are transplanted into the hemisected adult rat spinal cord after purification and condense and enclosed by L I -antibody. Eight weeks later, the experiments of the S- 100 immunohistochemistry indicate that Schwann cells are still alive and array orderly relatively.

本实验的主要研究内容及结果如下： 1、雪旺细胞的培养及免疫组化染色利用新生S-D大鼠的坐骨神经成功地分离、培养获得了纯度较高的雪旺细胞，并将雪旺细胞移植进入大鼠脊髓损伤创面，饲养8周后经过S-100免疫组化ABC染色发现雪旺细胞在大鼠体内成活良好并成簇排列。

At least 0.1μg/ml of endotoxin can induce the morphologic changes and the decrease of F-actin in HUVECs. Endotoxin can injury HUVECs only when its concentration reaches 0.4μg/ml and incubates over 12 hours. It suggests there is a different molecule mechanism in VEC from the endotoxin-CD14 pathway in CD14 positive cells.

内毒素直接损伤血管内皮细胞须较大浓度(＞0.4μg/ml)，但在较低浓度下(0.1μg/ml)可直接引起内皮细胞的一些形态学变化和F-actin含量的变化，初步推测血管内皮细胞可能存在着与通常认识的内毒素—内毒素结合蛋白—CD14途径激活细胞不同的分子机制。

Meanwhile, in order to explore the stability of gene expression and the properties of gene-modified bone marrow cells further, we have observed the capability of reconstituting hematopoietic system of gene-modified and the expression of transduced gene in vivo by using of BMT to engraft lethally irradiated mouse with the gene-modified bone marrow cells.

同时，为进一步探讨转导细胞基因表达的稳定性以及生物学特征，本实验通过骨髓移植的方法，将基因标记骨髓细胞移植给受致死量照射小鼠，观察了基因转导细胞重建体内造血的能力，以及造血重建后外源基因在脾结节及骨髓细胞的表达。

Here, using a strategy of re-expressing key developmental regulators in vivo, we identify a specific combination of three transcription factors Ngn3 (also known as Neurog3 Pdx1 and Mafa that reprograms differentiated pancreatic exocrine cells in adult mice into cells that closely resemble beta-cells.

这里，在体内通过一种策略将生长发育中关键的调控因子进行再表达，我们鉴定出了一系列3个转录因子（Ngn3 (亦称 Neurog3)，Pdx1 和 Mafa），将它们重组入成年小鼠的胰腺外分泌细胞，相应的细胞可分化成类似于β细胞的细胞。

The injured gill cells had a different ultrastructure, with endoplasmic reticulum dilated and vesiculated, mitochondrial cristaes partially disintegrated, gill fibre cuticles denatured and dropped. The ultrastructural damages to hepatopancreatic cells were characterized by the decrease of microvilli, swelling and breaking up of mitochondria, expansion of endoplasmic reticulum, disruption and vacuolization of nucleus, tumefaction of nuclear membrane and increase of lipid droplets. As for the toxicological changes of myocardial cells, the mitochondria were swelling, having a lot of vacuolus and disintegrating, while the myofibrils were irregular with endoplasmic reticulum dissolved.

鳃细胞的损害表现为鳃丝水肿，细胞器溶解，角质层变薄，线粒体、内质网的肿胀、解体；肝胰脏细胞的主要损害特征为肝管微绒毛减少，线粒体水肿解体，内质网扩张，细胞核空泡化，核膜水肿和脂肪滴增加；心脏细胞的毒理变化为线粒体内嵴肿胀、瓦解，肌原纤维不规则，内质网溶解。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
