查询词典 Vesicles

Results Pycnosis and deep staining of neurons, deposits of synapse vesicles and bluring of synapses, fusion and dissociatio of myelin sheaths which were exposed to 10, 50 and 90 mW/cm^2 HPM were observed. The contents of the above four amino acids elevated more markedly on 6 h than those of controls, but on 1 d only the elevation of GABA and glycine after exposure to 10 and 50 mW/cm^2 HPM was observed.

结果平均功率密度10，50和90mW/平方公分S波段高功率微波可引起大脑皮层神经元固缩、深染，尼氏体减少；突触结构模糊，囊泡堆积；髓鞘融合、解离等。10和50mW/平方公分组照后6h大脑皮层上述4种氨基酸含量均显著增高(P.01)；而照后ld仅见γ-氨基丁酸和甘氨酸含量仍较高(P.01)。

According to the preview study, the low dielectric constant will reduce the self-oxidation of the pyrogallic, which lead to the result of the lower self-oxidation rate in vesicles than that in solutions.

根据前面的研究结果，低的介电常数会抑制其自氧化，因此就出现了在囊泡中自氧化速率低于在水溶液中的现象。

The activty of SOD in vesicle solution is then determined. But still no apparent superactivty is found due to the following reasons: 1. The lowered dielectric constant reduces not only the self-oxidation rate of pyrogallic, but also the activity of SOD; 2. There are no efficient enough interaction between vesicles and SOD.

在上述体系中进行的SOD的活性研究中，没有发现表观超活性，估计是两方面的原因：一是囊泡周围低的介电常数同样也降低了SOD酶的活性，二是由于表面活性剂浓度较小，仅为0.5％左右，使得囊泡体积分数较小，不能与SOD酶发生充分有效的结合。

Results: The cultured chondrocytes were polygonal cells. There were many rough endoplasmic reticula and mitochondria in cytoplasm, and a lot of secretory vesicles under cell membrane and in the cytoplasm. When cultured for 10 days, some small and white nodules were formed on the bottom of the culture dished, and volcanic-mouth-like structures were formed when cultured for 20 days. Both these nodules and structures contained GAG-positive substances were demonstrated by safranine-O staining.

结果：体外培养的软骨细胞为多角形，透射电镜下见胞浆内有丰富的粗面内质网系统及线粒体，胞膜下及胞浆中有较多分泌泡；连续培养10天时，培养瓶底部出现肉眼可见的白色结节，蕃红-O染色显示白色结节含大量氨基葡聚糖阳性物质，20天时形成火山口样结构，也被蕃红-O染成深红色。

The results showed that,in spiteof many ultrastructural changes of the fruit epidermis cells during the fruit development,itremained almost unchanged that the cytoplasm was filled with numerous endoplasmic reticulathroughout the whole developmental process.Most of these endoplasmic reticula were tube-likeand rough-ER with enlarged cisterna from which were produced many vesicles. Some of thevesicles were shown to merge into vacuole and to traverse through plasmadesmata.

结果表明，虽然不同发育期果皮细胞的超微结构发生了变化，然而最引人注目的是，内质网自始至终密布于整个细胞质中，而且大多为槽库膨大的、合成功能旺盛的管状粗面内质网，并分泌出大量的具运输功能的小泡：观察到这些小泡与液泡融合和穿越胞间连丝的景象。

A lot of organelles such as mitochondria, rough endoplasmic reticula and Golgi bodies were observed in fiber cell. Then, double karyotheca disappeared, and the organelles disintegrated. Multivesicular bodies appeared in fiber cytoplasm. With the further development of fiber, fiber wall underwent continual thickening with aging, and polylaminate structure gradually appeared. While the agglutinated nucleus, transfer vesicles, plasma membrane and plasmodesmata still presented.

研究发现，次生壁形成早期，细胞核具有双层核膜，染色质凝聚，可见大量的线粒体、粗面内质网和高尔基体等细胞器存在于纤维细胞中；随后，双层核膜消失，细胞器将逐渐解体，多泡体开始出现在纤维细胞的细胞质；随着年龄的增加，纤维细胞壁逐渐增厚，并出现多层结构现象，而运输小泡、细胞膜、胞间连丝和凝聚的染色质将持续存在。

A novel polymer of Poly(diglycidyl maleate-co-stearyl methacrylate) was synthesized and its structure was characterized by ~1H NMR. Its self-assembly behavior was studied in different solvents. It was found that vesicles and tubule-liked aggregates can be obtained through self-assembly of P(DGMA-co-SMA)/THF/EtOH system. And spheral aggregates were obtained in P(DGMA-co-SMA)/THF/H_2O system while the spheral aggregates were converted into rod-liked aggregates and line-liked aggregates after aged for different time.

合成了带含环氧基侧链和十八烷基侧链的聚(马来酸二缩水甘油酯-co-甲基丙烯酸十八酯)，用~1H NMR对所得的共聚物进行了表征；研究了其在选择性溶剂中的自组装行为，发现P(DGMA-co-SMA)／THF／EtOH体系可以通过自组装形成囊泡形自组装体和支化的管状自组装体，P(DGMA-co-SMA)／THF／H_2O体系最初自组装形成球形自组装体，随着陈化时间的延长，球形自组装体逐渐融合成长条形自组装体和线形自组装体；探讨了自组装过程的机理，建立了可能的自组装过程模型。

The mixture of Galpi plus sucrose appeared to protect phospholipid vesicles during dehydration and rehydration to the same degree as did raffinose or the stachyose plus sucrose mixture.

甲基肌醇半乳吡喃糖和蔗糖混合对人工脂囊膜保护作用，其结果与棉子糖和蔗糖混合之保护作用相同。

During the wall thickening, the number of Golgi bodies increased apparently and cytoplasm was filled with Golgi vesicles. Polylamellate structure of the secondary wall appeard, Along with the further development of tracheary elements, the nucleous disappeared and organelles were decreased, while cortical microtubules were arranged neatly against the inner side of plasmalemma.

初生壁与质膜之间有间隔较规律的次生壁突起；中期，线粒体和高尔基体的数量明显增加，细胞质中几乎充满高尔基体及其囊泡，次生壁中微纤丝已成有序排列；晚期，细胞核消失，导管中央形成空腔，细胞器迅速减少，仅观察到少量高尔基体和线粒体，有大量周质微管沿细胞长轴分布，且在次生壁的周围有大量小泡附着，次生壁的分层结构清晰可见。
