组织上

Higher frepuency of germination , lower frequency of abnormal seedling , rapid growth and tender plantlets of Matthiola incana were obtained from the seeds cultured on MS basal medium without any hormone , which helps in inducing calli .

紫罗兰组织培养的研究(1)愈伤组织诱导及植株再生的研究：紫罗兰种子在不含任何激素的MS培养基上，发芽率高，畸形苗率低，幼苗生长快速，较鲜嫩，有利于愈伤组织的诱导。

Based on the deep comprehending of the organization in a university, this paper analyzed their shortcoming, and designed a meshy hierarchy that is more suitable for a university.

文章在对大学的有机组织进行分析的基础上，分析了现有一些组织结构的缺点，并设计了更适合大学的网络化层级组织。

Firstly, callus induction and subculture for Mikania micrantha were studied systematically. The research on callus induction showed that: Shoot tip has higher induction rate than other explants ; At 25℃ and dark regime, the callus was better cultivated on Murashige and Skoog medium (pH5.8) containing 2.0mg/L 2,4-D and 1.0mg/L KT.

首先，对微甘菊愈伤组织诱导和继代增殖培养进行系统研究，愈伤组织诱导研究表明：外植体中芽尖诱导率最高，在含2，4-D2.0mg／L、KT1.0mg／L、pH5.8的MS培养基上25℃黑暗条件下愈伤组织诱导效果较好。

Methods SP immunohistochemistry was used to detect actin expression in normal breast tissue, grade Ⅰ,Ⅱ and Ⅲ atypical hyperplasia and breast cancer. Electromicroscopy was used to observe the changes of ultrastructure of myoepithelial cells.

用免疫组化SP法分别检测正常乳腺组织、Ⅰ级一般性增生和Ⅱ级、Ⅲ级不典型增生乳腺组织及乳腺癌组织中肌动蛋白的表达情况，并用电镜观察肌上皮细胞超微结构的变化。

Histologically, nodules of adipose and myxoid tissue were demarcated by bands of fibrous tissue.

组织学上，根据纤维组织的带状中性粒细胞区分脂肪和黏液组织结节。

We found that 1 mutant EG4 cells showed typical characteristics of pluripotent stem cells which had no obvious difference with wild cells; 2 When induced by 10〓 M retinoic acid , mutant EG4 cells differentiated into adipocytes with high frequency compared with mutant cells, suggested that EGFR plays a role in adipocyte differentiation; 3 when injected into nude mice, mutant teratocarcinomas contained a large amount of connective tissues as well as skeletal muscle, while wild EG4 cells produced frequently cartilage, keratinocyte and neuroepithelium.

我们建立了稳定表达胞内区功能缺失的外源EGFR cDNA片段的EG4细胞，分析其生长分化特性，发现 1）突变型细胞可在未分化状态下维持长时间的增殖，表明EGFR对EG多能干细胞表型无明显影响；2）〓 M的维甲酸A(retinoid acid A，RA)诱导后，大部分对照组细胞分化为脂肪细胞，而突变型细胞分化为脂肪细胞的比例明显较少，表明EGFR在脂肪细胞的发育分化中具有一定的调节作用；3）畸胎瘤切片分析显示，突变型瘤组织分布有大量的未分化细胞和结缔组织，分化细胞以肌肉细胞为主；对照组瘤组织含丰富的角质上皮、软骨、神经管等依赖EGFR的分化组织。

Tissue engineering is a multidisciplinary science merging with cell biology, material science, engineering and chemistry. Its basic idea is to expand a number of cells in vitro and seed them on a polysynthetic biodegradable polymer structure, and finally enable the organization of 3-dimmentional and functional tissues or organs.

组织工程技术是融合了细胞生物学、材料科学、工程学和化学的一门边缘学科，它的基本思想是用少量组织细胞经体外培养扩增后播种在可降解的生物支架材料上，再回植入体内形成有功能的组织或器官。

Methods we designed the single incision on the postmedial line of the cranium and dissectted bluntly under aponeurosis of occipitofron talis muscle. after lifting the temple tissue sufficiently,we resected superfluous scalp and sutured demixing.

将手术切口设计在颅后中线上，从帽状腱膜深层钝性分离，进入颞区在颞浅筋膜深分离至眶外侧，充分上提颞部组织后切除多余头皮组织，最后分层缝合。

They also share some overlapping histological features. Thus, it can be difficult both radiographically and histologically to distinguish these neoplasms.

两者在组织学特征上存在部分类似，因此较难从X线摄影与组织结构上区分这两个肿瘤。

Different types of LIDH were not only exhibit morphological differences,they were also different histologically.The higher capillary infiltration rate of the extruded LIDH might be responsible fot its resorptive process and severe clinical findings.

腰椎间盘突出的不同病理类型不仅是形态学上的差异，也具有各自不同的组织学基础，破裂突出组织的较高血管浸润率很可能与其较严重的临床表现以及较明显的组织吸收过程相关联。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
