The results indicated that the mutant protein promoted the survival of dorsal root ganglion、induced TF-1 prolification and made the normal mice lose weight,decrease appetite and reduce fat index.The weight loss effect was dependant with its administration dosage,ED50 was 150.986?

结果是突变体蛋白能促进鸡胚背根神经节的生长；促进TF-1细胞增殖，MTT测定法表明突变体蛋白与国际参考品相比，比活不低于2.0×106U/mg；使正常小鼠的体重减轻，摄食量减少，脂肪指数下降，并且体重的减轻与突变体蛋白的给药剂量呈现良好的剂量依赖关系，其ED50为：150.986？

It includes three-stories of initials in the protomeristem of the root tip.

实验观察表明，甜菜根尖的原分生组织有三层原始细胞。

The immunohistochemical location of noncollagenous protein, bone sialoprotein , osteopontin and osteocalcin at different stages following periradicular surgery was undertaken. The crystals formation on surfaces of MTA was evaluated when treated in different conditions without cells in vitro and in vivo. MTA was used to manage clinical problems, including perforations in roots or furcations, and pulpless permanent teeth with incomplete root formation. The study included the following three parts

本研究试图通过体内外研究探讨MTA表面牙骨质形成的机理，动物体内动态观察根尖周组织在用MTA倒充填后的组织反应和细胞外基质非胶原蛋白的表达，体外观察MTA在不同的环境下表面的形态及成分变化，和在体内环境下材料表面磷灰石层的形成，同时结合临床病例观察其临床治疗效果。

MTA was used to manage clinical problems. These included pulpless permanent teeth with incomplete root formation and perforation in roots or furcations. Total 10 cases (12 teeth), former 7 cases (7 teeth) and latter 4 cases (5 teeth), were present. The follow-up periods were various from 6m to 21m.

应用免疫组织化学手段，观察细胞外非胶原蛋白骨唾蛋白（bonesialoprotein，BSP）、骨桥素（osteopontin，OPN）和骨钙素（osteocalcin，OC）在根尖周组织愈合期间的表达，尤其是在与倒充填材料直接相邻区域的表达。

Pycnosis occurred dose- and acidity-dependently in 10~180 mg/L Al(superscript 3+)-treated V. faba root cells.

模拟酸雨与高浓度的Al(上标 3+)(10~180 mg/L)复合处理可引起根尖细胞固缩，固缩率随Al(上标 3+)浓度增加和pH降低而增高。

"Superficially resembling higher plants, stoneworts have rootlike and stemlike structures, as well as whorls of branches at regular intervals."

轮藻的外观似高等植物︰具根状假根和按一定间隔出现的轮生分枝，直立的圆柱形中轴外围以由小细胞组成的鞘

Tumefaciens-mediated genetic transformation system of Roselle callus, AtPSK2 gene was introduced into and expressed functionally in Roselle cells.

利用玫瑰茄愈伤组织遗传转化体系，通过根癌农杆菌将AtPSK2基因导入玫瑰茄细胞，并获得了功能性表达。

The aim was to understand the mitotic chromosome aberrations in root tip cell of industrial polluted Stellaria media and micronucleus.

［目的］了解工业污染区繁缕根尖细胞有丝分裂期染色体的畸变和微核。

The results showed that the growth of Jinguang plum seedlings were remarkably restrained by salt stress. With the increasing of salt concentration, the plant height, leaf area, leaf fresh weight, leaf dry weight, stem dry weight and root dry weight were remarkably decreased, and the chlorophyll content, photosynthesis rate, transpiration rate and stomatic conductance in leaves were declined too, but the intercellular CO2 concentration was inclined.

结果表明盐胁迫抑制了金光杏梅幼苗的生长，随着盐浓度的升高，金光杏梅的株高、叶面积、叶鲜重、叶干重、茎干重、根干重均显著降低；叶片叶绿素含量、净光合速率、蒸腾速率、气孔导度亦显著降低，且盐浓度越高，下降幅度越大；细胞间隙CO2浓度随着盐浓度增加而增大，表明盐胁迫下非气孔因素是导致金光杏梅叶片光合速率下降的主要原因。

Many studies have revealed that apoptosis is an important and normal part in plant embryo development, tracheary element formation and development of root, shoot, leaf, flower.

大量研究表明，细胞凋亡是植物胚胎发育，导管分子的形成，根、茎、叶、花等器官正常生长发育的重要组成部分。
