胞质

In light and electronic microscopy, they appeared cell shrinkage, cell density increasing and eosinophilic, aggregation of cytoplasmic organelles, nucleolus fragmentation, and chromatin margination, condensation, and fragmentation. Those changes could be detected by TUNEL method.

在光镜和电镜下癌细胞凋亡表现为细胞体积缩小，胞浆浓缩嗜酸性，胞浆出泡、细胞器缩小或减少，核仁松解，染色质聚集、靠边、浓聚、断裂，在TUNEL法检测凋亡癌细胞时也可观察到相应的形态特点。

Results］the gross morphology of the tendons showed the experimental group had lesser adhesion and better reactiveness than that in the control group.the fibrin had degraded at 3 weeks. cell tracing showed that the labeled bone marrow derived mesenchymal stem cells remained viable and presented in the intratendinous region for at least 6 weeks, becoming more diffuse at later timepoints.at 3 weeks, collagen fibers appeared more organized and there were better morphometric nuclear parameters in the treatment group. at 6 and 12 weeks, there were no differences between the groups with regard to morphometric nuclear parameters.

结果］实验组相比对照组肌腱大体观察粘连差，肌腱活动性好。3周后纤维蛋白载体即降解，细胞示踪结果显示标记的骨髓间充质干细胞至少6周内仍可保持活性并存在于肌腱组织中，但之后逐渐扩散。3周时，实验组与对照组相比胶原纤维排列更为有序，且胞核形态结构更规则，但在6周及12周时，实验组与对照组胞核参数测定无统计学意义。3周时实验组比对照组具有更强的的生物力学特性，但之后则差别不明显。

EGF was mainly located in the cytoplasm and extracellular matrix of intestinal villus cells, endothelial cells and tunica serosa epithelial cells, while EGFR chiefly distributed in the cellular membrane of these cells.

其中 EGF主要存在于小肠黏膜上皮细胞、黏膜下层的血管内皮细胞内和浆膜上皮细胞的胞浆和胞外基质中，EGFR则分布于这些细胞的细胞膜上。

RESULTS: After co-culture, morphology of bone marrow stromal stem cells was changed, showing that flat cells began to retract and became spindle-shaped and some cells displayed a linear arrangement like Schwann cells.

结果：共培养后的骨髓基质干细胞形态发生改变，原来宽大扁平的胞体开始收缩，细胞胞体呈梭形，部分细胞类似施万细胞呈线性排列。

Most endothelial cells fell off, elastic fibre autolyze; the number of SMC decreased, some SMC nucleus contracted completely or depressed, typical apoptosis body were seen in later stage, muscle silk autolyzed and disappeared mostly; in outer layer saw much collagenic fiber, arranged unorderly; inflammation cells were seen in the aneurysm wall(hypertrophy cell et al.).

多数瘤壁的内皮细胞溶解脱落，不连续，弹力纤维自溶；动脉瘤血管壁均可见SMC明显减少，较多SMC染色质边聚、固缩，部分SMC核全部固缩或出现不规则凹陷，SMC核胞浆或胞核部分出现脱落或裂解成碎片，晚期可见典型的凋亡小体出现，肌丝大都自溶消失：外膜可见大量的胶原纤维，排列较紊乱；瘤壁还可见炎性细胞浸润。

The ultrastructure characters of pollen grain in Brassica napus are:1There are vacuoles in cytoplasm but no starch grain in uniceelluar pollengrain.2The veget- ative nucleus of bicellular pollen grain is generally spheroidal;while the generative cell is spinde-shaped,with a big nucleus,thin layer of cytoplasmand few cell orgens,no cell wall.3In three-celled pollen grain the sperm cell is separated from the cytoplasm of vegetative cell by two layers of plasmic membrances.

Brassica napus的花粉粒，在不同发育时期超微结构的特征如下：1单胞花粉粒有一个球形的细胞核和明显的核仁，细胞质内出现液泡，缺少典型的淀粉粒。2双胞花粉粒的营养核多为球形。生殖细胞纺锤形，无细胞壁，细胞核比例大，细胞质呈薄层，细胞器少。3三胞花粉粒有一个裂片状的营养核和两个纺锤形的精细胞，精细胞无壁，以两层质膜与营养细胞的细胞质相隔。

However, part of STxB had showed characteristics of the endoplasmic reticulum staining, suggesting weaker binding strength had influenced the transport rate from early endosome/recyling endosome to the Golgi apparatus.

但是部分STxB已呈现内质网定位特征，暗示着与受体结合能力的减弱影响了从早期胞内体/循环胞内体到高尔基体的运输速度。

Results The expression of the Mahoganoid protein and its mRNA was showed by brown staining and observed in the Leydig cells, spermatogonia, primary spermatocytes, spermatids, Sertoli cells, and peritubular myoid cells of testicular tissues and principal cells, basic cells and epithelial cells of epididymal tissues.

结果1。免疫组化法检测Mahoganoid蛋白的实验结果显示的棕色阳性信号可见于各天龄段大鼠睾丸的生精细胞、支持细胞、间质细胞和管周肌样细胞以及附睾输出管的高柱状、低柱状上皮细胞和附睾管的上皮细胞、主细胞、基细胞。其中Mahoganoid蛋白主要表达于胞膜和胞浆。

By use of perineurial recording technique in cutaneous pectoris of frog, we observed the effects of TSN on calcium currents in motor nerve terminals.

鉴于TSN主要生物学效应与胞内外钙离子密切相关，本文以不同方法研究了TSN对运动神经末梢钙电流、细胞胞内钙浓度以及对神经递质释放装置钙敏感性的影响，以期阐明TSN的作用机制。

The cell in acidic situation presented a degenerative chang-ment,such as an increased lipid drop and empty cavity in the cell plasma,a py-knotic nuclei,the dilatation of the endoplasmic reticulum and Golgi saccules,mi-tochondrial swelling the number of ribose decrease,and the ribose dissociated inthe plasma,a lot of swallowing cavity,the fibric material decreased accompany-ing with the acid being stronger.

随培养基pH逐渐下降，上述过程因受酸性阻抑而延缓，细胞增殖速度也受影响，处于酸性环境中的软骨细胞呈退行性变化，表现为细胞浆内脂质颗粒与小泡增多、细胞核皱缩、核仁浓染、内质网线粒体膨胀、核糖体数目减少，且与粗面内质网结合的少，游离在胞浆中的多。

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％。
