The human cartilages are composed of chondrocyte and extracellular matrix , the form of chondrocytes are hypertrophy and the quantity are less; the ECM of cartilage are compised of type Ⅱ collagen and proteoglycan. Articular cartilages are all hyaline with little fibers. Trauma and arthritis are the main cause of cartilage injury, the ommilayer injury ofcartilage can be recovered by marrow, but because of without stimulation mechanism, the new tissues are merely fibrocartilages, they can not be coincide with hyaline cartilage in menchanics; the purely damage of articular cartilage can not stimulate chondrocyte to regenerate because of without blood circulation, thus, the plerosis of articular catilage can not depend on the proliferation of local chondrocyte. Ever since, people tried their best to find a way to reconstruct articular cartilage.

中文题名人骨髓基质干细胞成软骨诱导及多孔复合材料作为细胞载体的体外实验研究副题名外文题名 Cartilage induction of human mesenchymal stem cells and experiment on compound porous materials as cells' scaffold in vitro 论文作者刘晓岚导师周江南学科专业外科学研究领域\研究方向学位级别博士学位授予单位中南大学学位授予日期2003 论文页码总数68页关键词骨组织工程软骨细胞骨髓基质干细胞壳聚糖高分子外消旋聚乳酸馆藏号BSLW /2003 /R68 /10 造成人体关节软骨损伤的原因主要为创伤和关节炎，关节软骨全层损伤可由于骨髓中间充质干细胞的高速增殖修复，但这种修复由于缺乏相应的刺激机制，只能形成纤维软骨，而不能形成符合关节生理、力学要求的透明软骨；单纯软骨部分损伤软骨组织内无血管，软骨细胞迁移迟缓，无法使损伤区域软骨细胞再生，因此，关节炎及关节创伤后的软骨修复不能依赖于软骨细胞的增殖和迁移。

The morphology of virions seems to not be change after incubated with the paeonol by electron microscope. The regained infectivity of TMV recovered by dialysis from incubation with paeonol in vitro showed that the paeonol have not direct viricidal effect. The paeonol did not reduce infectivity when applied before TMV inoculation. The paeonol in low concentration can restrain the polymerization of TMV coat protein in vitro. The paeonol did not reduced infectivity of TMV-RNA in vitro. It is proposed that the paeonol inhibited TMV by binding with TMV coat protein to interfere with recognition of a host receptor essential for infection or by interfering TMV-CP polymerization in plants. The anti-TMV activity of low molecular weight chemicals extracted from Polygonum cuspidatum were determined.

丹皮酚与TMV混合，电镜下观察对粒体形态没有影响；TMV与丹皮酚混和后透析可恢复侵染力，表明丹皮酚对病毒粒体并没有直接毒害作用；预先用丹皮酚喷施叶面不影响病毒的侵染，表明丹皮酚未干扰TMV对叶片侵染位点的识别；丹皮酚在低浓度时可阻碍TMV-CP的体外聚合，对TMV-RNA并无体外抑制侵染作用，据此推测丹皮酚对TMV的抑制作用可能主要通过其与TMV-CP结合影响病毒粒体对叶片表面侵染位点的识别，或影响体内TMV粒体的脱衣壳或TMV-CP亚基的体内聚合。

Blade according to claim 23, characterised in that the two bundles of rovings of the spar are pressed against one another by their portions (51a, 51b) passing through the blade footing (43), between the looped root portion (48) and the portions of the halves that are engaged and held applied against one another in the shell (44) so as to form the sole bundle (5) of the spar.

刀片根据索赔23 ，特点是在这两个捆无捻粗纱的SPAR公司是压一由他们的另一部分（ 51A条， 51B条），通过叶片的基础上（ 43 ）之间，环根部分（ 48岁）和部分该部分是从事和举行的适用对一另一个在蚬壳公司（ 44 ）从而形成唯一的束（ 5 ）的SPAR公司。

Blade according to claim 7, characterised in that the two bundles of rovings of the spar are pressed together in their portions (11a, 11b) traversing the blade footing (3), between the looped root portion (8) and the portions of the halves that are engaged and held apart from one another in the shell (4), so as each to form one of the bundles (10a, 10b) of the spar.

刀片根据索赔7 ，特色是在这两个捆无捻粗纱的SPAR公司是同时按下在其部分（第11 A ， 11 B款）穿越叶片的基础上（ 3 ）之间，环根部分（ 8 ）和部分的边认为所从事的举行，除了从一个另一个在蚬壳（ 4 ），使每形成1对束（ 10 A条， 10 B条）的SPAR公司。

直观以复合体脱离热压滚筒后亮度高，不发雾，平度好，无起泡为基准，在这样的温度区域内，热熔胶从外表到内部深处，整个都可以充分接受热力的作用，胶体内各种原材料共混后的改性可以得到充分的发挥，整个胶层彻底熔融，产生了真正的、牢固的粘结，而非表面的、浅层次的、经不得折弯或再加热出现的离壳、起泡现象。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
