包囊

This paper reviewed the research progresses about the cysts, especially the resting cysts of protozoans, mainly focused on the characteristics of morphologies, structures, constituents, and living activities, as well as molecular mechanism and significance of encystment for the protozoans, also, cell behavior during encystment and excystment was involved based on the references reported.

以国内外文献报道为依据，综述了原生动物包囊，特别是休眠包囊的研究进展情况，主要集中在包囊的形态、结构、组成、生命活动特征、包囊形成的分子作用机理和意义，以及包囊形成与解脱过程中细胞行为上的研究等方面。

During encystment, organelles displaying characteristics of autophagic vacuole appear in the cytoplasm of the cortex and part of ciliate structures and other cell components are digested by these organelles.

Results All of 4 form including vacuolar form, granular form, ameba form and cyst form were found in each culture medium, separately, and main reproductive mode is binary fission, a few of gemmation was exist.

结果在两种培养基中均可见到人芽囊原虫的四种主要形态：空泡型、颗粒型、阿米巴型和包囊型，其繁殖方式以二分裂为主，可见少量出芽生殖。

In resting cysts, the microtubules under the pellicle, cortical ciliatures, conjunctions between cilia basal bodies, supporting structure of basal bodies and other microtubule structures are absorbed in different extent; microtubule-like assemble bodies appear at the center of the remained cilia basal bodies; the granules of chromatin and nucleolus in macronucleus become smaller whereas nucleus pores of the micronucleus become bigger; the inner membrane of some nucleus pores are attached with chromatin.

结果表明：纤毛虫形成包囊过程中，皮层细胞质中产生具有自噬泡消化特征的细胞器，将部分纤毛结构等逐步消化；休眠包囊中，表膜下微管、皮层纤毛器和纤毛基体间连接、基体托架及其他微管结构不同程度地被吸收、在残剩纤毛基体的中央形成微管形结构聚合体，大核染色质和核仁颗粒变小，核孔增大，并发生染色质附着于核孔内膜的现象；细胞脱包囊期间，皮层细胞骨架、线粒体等经历了在残剩结构基础上的再分化。

When the cysts reach the intestine of another person the individual amoebae are released from the cysts and are able to cause infection.

当包囊联络另外的一个人的肠个体的时候阿米巴被从包囊释放而且能够引起传染。

The cyst wall of Tachysoma pellionella consist of four morphologically distinct layers, which are ectocyst, mesocyst, endocyst and granular.

急纤虫在形成包囊后，包囊壁分为四层，从外向内依次是外层壁、中间层、内层壁和颗粒层。

After selective extraction, the cyst wall of two kind of resting cysts displayed a filament network. In the resting cysts of Tachysoma pellionella and Euplotes encysticus, the filament was located in mesocyst and endocyst respectively. On the other hand, a special filament scaffold region was observed below the cyst wall in two kind of cysts. Compared with the true IF which was located in central part of cyst, the filament of this region was net as well as uniform, and no any cytoplasm residue can be seen in this region. In the resting cyst of Euplotes encysticus, a filamental boundry which partitioned the special filament scaffold region and the true IF region was observed.

两类休眠包囊的包囊壁经生化分级抽提后均显示纤维结构，急纤虫休眠包囊中纤维定位于中间层，包囊游仆虫休眠包囊中纤维定位于内层壁；其次，在两类休眠包囊的包囊壁下，相当于细胞质表质层的位置，均有一个特殊的纤维网络区，与细胞质深层的网络区相比，此部分的纤维纯净、均匀，未见附着细胞器及细胞质残留物，在包囊游仆虫休眠包囊中此纤维网络区与真正的细胞质纤维网络之间由纤维构成的界膜隔开。

In malignant room skin tumour early phase can see something without the aid of instruments in regular or opaque dirty tier or wall have a lot of white or the gray pellet and form festival or the lamina on tier of pleurae Piece with the development of tumour change thickly long and change thickly long full pleura surface tubercle the tumour tubercle stretches room skin to all sides postpone continuing becoming movie cyst lungs uses the person The cellar is getting smaller as shrinking more and makes to be put into much trouble inclining a chest wall subside.

在恶性间皮瘤早期，肉眼可见在正常或不透明的脏层或壁层胸膜上有众多白色或灰色颗粒和结节或薄板块，随着肿瘤的发展，胸膜表面愈来愈变厚，长满结节，间皮瘤结节向四方伸延，连续成片，包囊肺脏使其窖越缩。。。在恶性间皮瘤早期，肉眼可见在正常或不透明的脏层或壁层胸膜上有众多白色或灰色颗粒和结节或薄板块，随着肿瘤的发展，胸膜表面愈来愈变厚，长满结节，间皮瘤结节向四方伸延，连续成片，包囊肺脏使其窖越缩越小

The former formed a kind of KR cyst, while the later formed a kind of NKR cyst. All the kinetosomes, ciliary shafts and microtubules were resorbed in the former, meanwhile, the cell lost most water and cell volume decreased distinctly. In the later, only part of kinetosomes and part of microtubules were resorbed. Cell lost water slightly and volume decreased slightly.

期间，细胞吸收了全部的毛基体、纤毛杆和微管结构，伴随着细胞剧烈的失水浓缩，细胞体积显著缩小；游仆虫在形成毛基体非吸收型包囊时，细胞仅经历了部分的脱分化过程，期间，细胞仅吸收了部分的毛基体及部分微管结构，并且细胞仅发生了轻微的脱水和浓缩，细胞以折叠的形式容纳在包囊壁内。

Generally, the hearing did not recovery to an availabel level in patients either with silastic film or cartilage slice implants.

再次手术取出植入物时发现，硅片常被包裹在纤维结缔组织形成的包囊中，其周围仍有广泛粘连；同种异体软骨片植入者一般无这种包囊，周围粘连亦较轻，但无论是硅片还是软骨片植入或其它方法手术，它们的术后听力一般都达不到应用水平，其远期疗效更差。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
