查询词典 ameloblast

Immunohistochemical staining during different stages in ameloblast odontoblast and enamel free area cells were measured by the image analysis,the date of which was handled with SPSS11.5 software.

随后做图像分析测定不同发育阶段的成釉细胞、成牙本质细胞、无釉区细胞的免疫表达水平，所得数据用SPSS11.5 软件进行统计分析。

Results It was demonstrated that β-TrCP expressed in oral epithelium, tooth bud, mesenchymal cell cytoplasm of ameloblast and edontoblast of different stage of tooth development.

结果β-TrCP在胚胎10.5、13.5、14.5、16.5、18.5d的小鼠牙胚上皮层与间充质层，以及出生后0、3、6d的小鼠成釉细胞与成牙本质细胞胞浆呈特征性表达。

We reveal a case of ameloblast ic carcinoma of the mandible and report present illness, clinical exam, surgical therapy treatment and post-operation follow up in particulars.

本文提出一例罹患下颚造釉细胞癌的患者，就其发病过程、临床检查、手术治疗方式及追踪情形作一完整之报告。

There is a significant linear correlation between stratum intermedium cell and ameloblast in apoptosis and expression of PCNA and TNSALP.

中间层细胞先于成釉细胞表达TNSALP，出生后5d时即呈现强阳性染色，而后其表达又逐步减弱；成釉细胞7d时开始出现阳性，且呈逐渐增强趋势。

This finding corresponded to the immunohistochemical data showing the presence of phosphorylated forms of p38, c-Jun N-terminal kinase, and extracellular signal-regulated kinase during ameloblast differentiation.

这个发现与免疫组织化学数据相符，显示在成釉细胞的分化过程中，p38磷酸化形式，c-Jun氨基端激酶以及细胞外信号调节激酶均有表达。

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。

The results suggest that Smad4,one of the intracellular downstream molecules of TGF-β superfamily,and an inductive signal mediating epithelial-mesenchymal interaction,may regulate the differentiation of ameloblast and odontoblast cells,and modulate dentinogenesis and amelogenesis.

结论首次观察到Smad4信号分子在人牙胚发育过程中的表达，Smad4作为TGF-β超家族细胞内信号分子，可能参与上皮间充质的相互作用，同时也参与成釉细胞和成牙本质细胞的分化以及牙釉质和牙本质的形成。

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: Ameloblastin mRNA was negative under microscope in the ameloblast proliferate differentiation period, it showed weakly positive expression in intra-cellular and new-birth enamel matrix in secrete initial stage while it showed strongly positive expression in intra-cellular and new-birth enamel matrix when it came to secretion phase.

结果：釉鞘蛋白mRNA在成釉细胞增殖分化期表达为阴性，分泌初期细胞内及新生釉基质中开始出现弱阳性表达；至分泌期，细胞内及新生釉基质中均呈强阳性表达。

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。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
