So the influence of the RGD peptide on gingival fibroblasts and epithelial cells is similar.

因此RGD涂层对人牙龈上皮细胞和牙龈成纤维细胞生物学行为的影响相似。

Thus gp130 is the common signal transduction molecule. Gp130 molecule expresses universally on many tissues including immune system, hemapoietic system, and nerve system. Gp130 has an essential role in the function and regulation of the above systems, especially in the development of hemapoietic system. The signal transduced by gp130 is necessary during the differentiation and proliferation of hemapoietic cells. It is evidenced that the embryo of gp130 gene-knockout mouse was dead due to a serious impediment of the development of hemapoietic system.

Gp130在人体组织细胞上广泛性表达，介导和调节机体的免疫、造血以及神经系统的生理功能，尤其是在造血系统的发育过程中，具有极其重要的作用，动物实验表明，敲除小鼠的gp130分子基因可以使其在胚胎的早期阶段产生严重的造血系统障碍，最终导致流产，由此表明在造血细胞的分化、发育和生物学行为中，gp130介导的信号是必不可少的。

According to the research of the biology, physiology, psychology, the life comes and then have a kind of special ability, but this kind of ability hide hiddenly in people, canning not see clearly superficially, we calls this kind of ability as natural endowments that latent ability, namely people often say.

根据生物学、生理学、心理学的研究，人生来就具备一种特殊能力，但这种能力隐秘地潜藏在人们体内，表面上看不出来，我们称这种能力为潜在能力，即人们常说的天赋。

Studieson the rice reproductive organ mechanisms will be significant in theory and in practice.Now over 70 homeotic genes have been cloned from rice by using the conserved sequencesof the homeotic genes of dicots as probe screening the rice genomic library or cDNA.

属于单子叶植物，是发育分子生物学研究领域中常用的一种模式植物，同时也是世界上最重要的粮食作物之一，其花器官发育的结果直接影响稻谷产量和品质，因此对其花器官发育的研究有着深远的意义。

Proposes the concepts of nonlinear circulant system and nonlinear circulant switched system and develops correspondingly the mathematical models,which are extended from Hypercycle as a biological.

在生物学超循环系统的基础上，提出了非线性循环系统和非线性循环切换系统的概念，并建立了数学模型，这类系统具有广泛的实际背景。

Cases of tumor was performed by immunohistrochemical staining EMA and Vim were positive. 12 cases were hyperplasic lesions of mesothelial cell. Induced rats' MPM had a higher similarity with human' s MPM, especially in pathogenicity, positions, histological type and biological behavior of invasion and metastesis.

结果 实验组发生胸膜间皮瘤66例，诱发率71.74%，大体形态肉眼结节型间皮瘤较多见（72.73%）组织形态可见上皮型、梭形细胞型及混合型双向多潜能分化，13例免疫组化EMA及Vim双向阳性，并可见12例胸膜间皮细胞增生性病变，诱发瘤在病因，发病部位，组织形态学以及浸润转移的生物学行为方面与人体间皮瘤极为相似。

This thesis, basing on clinic experience and understanding of Tradional Chinese Medicial theory about tumor's etiological factors and side-effects of chemotherapy or radiation cure, studied total saponins of Sanguisorba officinal is effects and mechanisms of action on hypocytosis induced by radiation and chemical.

本课题根据中医理论对肿瘤及放化疗毒副作用病因和病机的认识，结合中医临床经验，以传统止血中药地榆为研究对象，在已有的研究基础上针对放、化疗致血细胞减少症，采用现代药理学研究方法和细胞学及分子生物学研究方法，深入探讨地榆总皂苷促血细胞生成的作用及分子机理。
