The organelles, such as Golgi bodies together with small vesicles, endioplasmic and reticulum play the key role in the formation of the secondary wall of helical tracheary elements in the stem of Cucurbita moschata, though cortical microtubules are correlative with the process as well.

高尔基体及其分泌小泡和内质网等细胞器参与了导管次生壁的形成，其中周质微管也起了一定的作用。

METHODS: The model of tissue damaged submandibular gland in 10 rats was made by deligation. One week later, the gland tissue was obtained to harvest submandibular gland stem/progenitor cells by enzyme digestion in vitro. Following 10-14 days of primary culture, small round cells were collected, purified and subcultured for monoclonal culture.

10只大鼠采用结扎下颌下腺主导管、抑制腺体分泌来建立组织损伤模型，1周后切取腺体组织，酶消化法体外分离下颌下腺干/祖细胞，原代培养10~14 d后，挑取培养皿中形成的小的类圆形、类上皮细胞集落予以纯化，传代后进行单克隆培养。

A conjugation small molecule containing both 3T moiety and diacetylene moiety is synthesized. It will be interesting to investigate the potential application in FET of the cubic organic semiconductor formed by topology polymerization.

合成了含有三聚噻吩(3T)和可引发拓扑聚合的双炔官能团的小分子光电材料，成膜后引发拓扑聚合形成&体型&聚合物半导体材料，探讨它在场效应管中的应用将是很有意义的工作。

What was observed under a light microscope included: tumor cells were mulberry and micropapillary shaped or were of glandule tubular arrangement; there was obvious interspace between cancer nest and neighboring areas; micropapillary was empty of fiber blood vessel axes, with micropapillae floating freely in spongy spaces and separated by fibrous septa.

光镜下特征性表现为肿瘤细胞呈桑椹状、微乳头状或小腺管样排列，癌巢与周围间质形成明显的空隙，微乳头缺乏纤维血管轴心，每个微乳头细胞团和周边的纤维组织均存在无细胞的间隙样结构；瘤细胞CerbB-2、CgA和EMA。

RESULTS: After differentiation of human adherent myoblasts by neural induction medium, no cells with a neural cell morphology (ie., small, refractile cell body with dendritic cell extensions) were seen. All remaining myoblasts cultured with neural induction medium, myoblasts with proliferation medium and myotubes with differentiation medium containing 20 mL/L HS were positive for β Tubulin Ⅲ. C2C12 myoblasts were negative for β Tubulin Ⅲ. In contrast, all the above cells were negative for the markers Neurofilament Mr 68×103 and GFAP.

结果：用诱导分化液作用后，未见小的、伴有突起的放射状形态的神经细胞；抗β Tubulin Ⅲ对经神经元胶质细胞诱导分化液作用后的人成肌细胞、增殖培养液培养后的各代人成肌细胞及仅含20 mL/L HS分化液分化形成的肌管细胞染色均为阳性； C2C12细胞β Tubulin Ⅲ抗体染色阴性；上述所有细胞抗Neurofilament Mr 68×103和抗GFAP染色均为阴性。

The histopathology showed that the tumors were rich in cells arranged in fascicles with bipolar and spindled processes. The nuclei showed minor pleomorphism. A few tumor cells were centered on the vessels with a nuclear-free zone that was characteristic of ependymoma.

病理组织学上肿瘤富于细胞，排列成束状、交织状，细胞胞突细长双极，核异型性小，少数肿瘤细胞围绕血管周围形成室管膜瘤的无核区结构。

Fruit a nut; male flowers with 2 bracteoles; thecae separate, pubescent at apex; bracts campanulate or forming a tubular sheath

果为一坚果雄花具2小苞片；囊分开，青春期的在先端；苞片钟状的或形成一管状的鞘 1 Corylus 榛属

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。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
