In addition, by calculating the bioaccumulation factor, the result shows that bioaccumulation ability of the Phragmites australis varies among the tissues, and the bioaccumulation ability of the root tissue that is prone to accumulate Pb and Cd is much higher than the stem and leaf tissues which are easy to concentrate Pb.

生物富集系数的计算结果显示，芦苇不同组织对有毒重金属元素的生物富集能力存在较大差异，根组织的生物富集能力最大，且容易富集Pb和Cd；而茎、叶组织的生物富集能力较低，易富集Pb。

In lung cancer tissues, benign phymatoid lesions, and adjacent non cancer lung tissues, telomerase activity was determined by telomeric repeat amplification protocol assay, and the expression of human telomerase RNA component, human telomerase reverse transcriptase, and human telomerase associated protein(hTEP1) mRNA were detected with reverse transcriptase PCR. The results were compared with the histological types, degree of differentiation, and TNM stage of lung cancer.

用 TRAP法检测端粒酶活性，用逆转录 PCR法检测肺癌组织、肺部良性瘤样病变和病灶旁非癌肺组织的 RNA成分（ human telomerase RNA component，hTR）、端粒酶逆转录酶（ human telomerase reverse transcriptase， hTERT）、端粒酶相关蛋白 1（ human telomerase associated protein， hTEP1）各亚基的 mRNA表达，其结果与肺癌的组织类型、分化程度及 TNM分期进行了比较。

Results In 9 cases of endometrial biopsy of materials by uterine curettage, the cells of endometrial stromal sarcomas of 6 cases were well differentiated and like stromal cells of endometrial hyperplasia; the cells of endometrial stromal sarcomas of 3 cases were poor differentiated, the cells of 2 were like that of malignant lymphoma, and another like that of pleomorphous sarcoma. In 9 cases were found the distribution of vessels cluster like endometrial corkscrew small artery. The tumor cells were grew along lymphatic or protruded in lymphatic, and there were small islands or small pieces of tumor cells in the interspace of muscles in 2 cases. The contrastive observation of the specimens of resected uterines of 9 cases confirmed the valve of above features to the confessed diagnosis of endometrial stromal sarcomas in the materials of endometrial biopsy or uterine curettage.

有3例分化差者，其中2例酷似恶性淋巴瘤，1例酷似多形性肉瘤。9例均见簇状分布的子宫内膜螺旋小动脉样的小血管分布，2例见瘤组织沿淋巴管和突入淋巴管内生长及小片平滑肌组织的肌间隙内有小灶状或小片状瘤组织分布。9例子宫切除标本的对比观察，进一步证实了上述特征对宫内膜活检或刮出物确诊子宫内膜间质肉瘤的价值。

Neurothekeoma and plexiform fibrohistiocytic tumor are dermal neoplasms that share many clinical and histologic features and whose histogenesis is equally disputed.

神经鞘黏液瘤和丛状纤维组织细胞性肿瘤好发于皮肤，两者的临床特点和组织学特征有许多相同之处，但两者的组织发生仍具争议。

Methods The expression of P73 in 92 cases of colorectal carcinoma tissue, 10 cases of colorectal polypous adenoma tissues, 34 cases of lymph node metastasis, 16 cases of liver metastasis, and 10 cases of normal colorectal tissues were measured by PV immunohistochemical approach.

选取92例大肠癌组织标本，腺瘤10例，淋巴结转移灶34例，肝转移灶16例，癌旁正常组织10例，通过免疫组化PV-9000通用型二步法检测P73在上述标本中的表达，分析P73在原发灶，转移灶，癌旁正常组织中的表达情况，与大肠癌临床病理参数的关系。

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。

The results of the physiological and biochemical indexes in callus tissue of Poncirus trifoliata tested under calcium carbonate(CaCO3) stress indicated that except total iron content, the negative correlations among CaCO3 concentration and peroxidase activity, superoxide dismutase activity, catalase activity, active iron content, soluble protein content and callus growth were recorded.

提要测定碳酸钙(CaCO3)胁迫下枳壳愈伤组织的某些生理生化指标的结果表明：除全 Fe 含量外，CaCO3浓度与过氧化物酶活性、超氧化物歧化酶活性、过氧化氢酶活性、活性Fe含量、可溶性蛋白质含量、愈伤组织增重均呈显著或极显著负相关，与培养液pH值呈显著正相关；随着培养的进程， POD活性、活性Fe和可溶性蛋白质含量、愈伤组织增重呈降低趋势， SOD和CAT活性先升后降，含高浓度CaCO3的培养液 pH值仅在20日左右略有降低。

As a representative organization of chinese youth's action against the climate change, with help form overseas forces, CYCAN premeditatedly and systematically provokes and leads the college students into the environmental protection course.

CYCAN 作为中国青年应对气候变化的代表组织，在海外组织的呼应下，有组织有预谋地煽动和指挥大量不明真相的青年学生参与到气候保护的行动中。--海因里希。伯尔基金会项目经理陈冀俍

Three major embryonic tissue systems,shoot apical meristem,root apical meristem,and the differentiation of procambial strands,were visible in torpedo-stage somatic embryo.

三种主要的胚性组织系统包括芽顶端分生组织，根顶端分生组织和原形成层束在鱼雷形胚阶段清晰可见。

The promeristem is consisted of three groups of initial cells, which have typical cytological characteristics of meristem cells. The primary meristem is composed of calyptrogens, primordial epidermises, periblems and pleromes. Both the calyptrogens and the primordial epidermises initiate from the same layer of initial cells.

原分生组织由3群原始细胞组成，其细胞具有典型分生组织的细胞学特征；初生分生组织包括根冠原、表皮原、皮层原和中柱原，其中根冠原和表皮原具有相同的起源。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
