Calcium as a second messenger transfers external signal ( hormone, light , temperature and other environal stimulates) to intracellular signal, and induces a series of intracellular affairs.

钙离子作为细胞内第二信使把外源信号(激素、光、温度等环境刺激)转变成胞内信号，导致一系列胞内事件的发生。

Positive rate was relatively high, and the foreign gene could also maintain in testicular tissue for a long time, it could still be detected in the tissue in 7 months after being injected. However. Deferent results could be gained when the detection were made with different primers on different sites of the recombinant plasmid. This could be explained by transgene lost when the foreign gene recombinated and integrated in heterogenetic cell, or transgene degradated by cell nucleases.

然而，我们也看到，在后代检测中，利用不同的引物扩增重组质粒不同部位时，检测结果存在差异，转基因阳性率不同，这种差异说明当外源基因进入到异源细胞内，在重组整合时发生了外源基因丢失的现象，并由此导致外源基因的整合率下降，也可能是受细胞内核酸酶的作用，使得外源基因遭到降解。

Results 20 cases of CT examination had made proper diagnoses,the CT imaging finding about the most of peripheral cholangiocarcinoma included:There was the atactic low density tumour in liver,its borderline was unclear,enhanced scan appearances were irregular peripheral enhancement,centripetal enhancement,and delaying enhancement;There was concretion and dilatation of bile buct in or around the focus;The local envelope of liver was lacunose and the local liver was atrophied,There was abroad putrescence and liquescence in the focus.

结果 20例CT做出了正确的诊断，部分周围型胆管细胞癌的CT表现肝内不规则低密度肿块边界欠清，增强扫描表现病灶边缘呈不规则环状强化，有向心性强化的趋势，出现延迟强化；病灶内或周围可见结石，病灶内及周围肝内胆管扩张；局部肝包膜回缩、肝叶萎缩，病灶内大片坏死、液化。

Furthermore,the changes of cell organelles realized different cell functions, which fiber for mechanical support,parenchyma cell for preservation and vessel for transportation.3.FE-SEM and DCR technique revealed the arrangements of CMfs on cell wall of fiber, parenchyma cell and vessel.Firstly,fiber cell formed multilamellate concentric structure with thin and thick lamellae alternate.

纤维、基本薄壁组织细胞、导管分子的终端分化就是PCD；并且PCD过程是一个具有较长周期的过程，周期长短比较为基本薄壁组织细胞＞纤维＞导管分子；三类细胞最后的凋亡决定于细胞内原生质体完全降解的时刻。

In the PbⅠ stage oocyte, perivitelline enlarged further, the cumulus cells expanded and the cell junctions disappeared. On the membrane of oocyte near the first polar body, a no microvillus area was observed, where probobly was the position for the second polar body extruding.

在PbⅠ阶段的卵母细胞内，卵周隙进一步扩大，卵丘细胞扩散，无细胞间连接存在，卵母细胞表面靠近第一极体的部位存在无微绒毛的区域，可能是第二极体释放的部位。

Therefore, the disruption of the actin cytoskeleton initiates a cascade of structural and functional alteration in renal epithelial cells and which will lead to the dysfunction of reabsorption in kidney.

肌动蛋白聚合形成了肾脏上皮细胞内对微绒毛起支撑作用的细胞骨架，因此肌动蛋白细胞骨架的破坏势必导致肾小管上皮细胞结构和功能的改变，从而引起肾脏的重吸收功能障碍。

So far, because of the components of AN are very complex, the mechanisms of AN-induced cytotoxicity to cause cell aberrations and oral diseases are not clearly understood. The purpose of this study is trying to investigate the roles of two check point kineses: Chk1/Chk2 in the ANE-induced geno- and cytotoxicity.

但由於槟榔成分过於复杂，对於槟榔成分究竟是如何造成各种细胞变异甚至口腔疾病的详细致病机转目前并不清楚，因此本篇研究的主要目的即是针对细胞内两种细胞周期检查点Chk1/Chk2在槟榔成分所造成的基因与细胞毒性中所扮演的角色进行探讨。

Positive nerve fibers are in pedal nerve cords and visceral nerve cords. There are no neuronal nitric oxide synthase or inducible nitric oxide synthase positive cells or fibers in the nervous system. A few of endothelial nitric oxide synthase strongly positive nerve cells are identified in pedal ganglia and visceral ganglia. Weakly positive cells and nerve fibers of eNOS can be seen in all of the ganglia and nerve cords.

免疫组化定位表明，神经型一氧化氮合酶和诱导型一氧化氮合酶在整个神经系统内均呈阴性；足神经节和脏神经节内有少量神经细胞呈内皮型一氧化氮合酶强阳性；各神经节和神经索内的部分小细胞和神经纤维呈eNOS弱阳性。

There is an apparent dissociation of β 2 AR induced augmentations of the intracellular Ca 2+ transient and contractility from cAMP production and PKA dependent cytoplasmic protein phosphorylation.

受体激活所引起的细胞内钙和收缩力的增加与细胞内环磷酸腺苷的增加和胞浆蛋白磷酸化有明显的脱节。

In mature stage,the organelle,such as dissociative ribosome,Golgi body,endoplasmic reticulum and nuclear,was disassembled quickly.

在此时期内，筛管内的游离核糖体、高尔基体、内质网、细胞核等细胞器迅速解体消失。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
