查询词典 dentin

After 16 weeks growth, continuous and intact ameloblast, enamel, dentin, odontoblast was found.

生长16周的人牙胚，已经形成连续完整的成釉质细胞，牙釉质、牙本质和成牙本质细胞层。

Results: The expression of both mRNA and protein of c-myc were obvious in the bud and cap stages,while decreased in the bell stage, then increased in ameloblast and dentinoblast when dentin formation. The expressions of c-myc were stronger in mesenchymal cells than in epithelial cells. The expression and distribution of c-myc mRNA is consistent with that of c-myc protein.

结果：c-myc mRNA及蛋白的表达在蕾状和帽状期明显，钟状期减弱，而牙体组织形成期成釉细胞、成牙本质细胞及间充质牙乳头细胞表达又增强。c-myc蛋白表达和分布与c-myc mRNA转录基本一致。

Results: The expression of both mRNA and protein of c-myc were obvious in the bud and cap stages,while decreased in the bell stage, then increased in ameloblast and dentinoblast when dentin formation.

利用原位杂交技术、免疫组织化学技术检测SD大鼠牙胚发育不同时期c-myc mRNA转录及蛋白的表达情况。

RESULTS: CaB was not detected during early odontogenesis from the dental lamina to the late c ap stage .Small amount of the protein first appeared in ameloblast and some of dif ferenting cells in the surface of dental papilla in early bell stage. As to late bell stage, the cytoplasm of ameloblasts and odontoblasts with secreted dentin was all stained strongly, as well as some of n uclei.

结果：人牙胚蕾、帽状期成釉器无CaB的表达；钟状早期成釉器的内釉细胞及部分牙乳头表面处于分化状态的细胞弱阳性染色；钟状晚期成釉器的成釉细胞、成牙本质细胞及部分胞核呈现强阳性染色。

Normal dentin is twice as stiff as pinewood, but damaged dentin is more like rubber, which makes it pretty hard to chew with.

正常的牙本质比松木还坚硬一倍，但是遭到损坏的牙本质却软如橡皮。

The results showed that the thickness of dentin substrate can have some influence on peak value of Maximum principle stress (Variation 4%). The influence sensitivity decreased with the increase of dentin thickness.

结果发现模型中不同牙本质厚度会对粘结界面的最大主应力峰值产生一定水平的影响(变化范围4%)，其随厚度增大敏感度逐渐下降。

Fibronectin usually appeared in dental pulp and predentin, and also in space between the wall of dentinal tubule and process of odontoblast in mature dentin, suggesting that it played an important role in network arrangement of fibronectin which maintained normal form and position of pulp cells and other structures in dental pulp-dentin complex, and also in limitation of diffusion of pulpitis.

纤维粘连蛋白-IR不仅见于牙髓与前期牙本质，而且也见于成熟牙本质的牙本质小管与成牙质细胞突起，它对维持牙髓牙本质复合体各结构的正常位置，形态和防止炎症扩散可能发挥了重要作用。

RESULTS: No reparative dentin was formed after 3 days of post-operation. The new-formed reparative dentin and osteodentin were observed after 15 days.

结果：术后3d未见修复性牙本质形成。15d后可见修复性牙本质形成，并可见骨样牙本质。

The family of glycophosphoproteins comprising osteopontin, bone sialoprotein, dentin matrix protein 1, dentin sialophosphoprotein and matrix extracellular phosphoglycoprotein — small integrin-binding ligand N-linked glycoproteins — are emerging as important players in many stages of cancer progression.

糖磷酸化蛋白包含骨桥蛋白，骨唾液蛋白，牙质基质蛋白及细胞外基质糖蛋白――小的整联蛋白结合配体 N 联结糖蛋白――作为癌症演进早期的一个重要物质。

In the group of lased 60s the dentin tubles appeared cracking and some dentin tubles were opened.

激光60秒组对根管壁有过分熔融，形成裂纹而且不能完全封闭牙本质小管。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
