胶原质

Objective: To explore the effects of Gymnadenia conopsea alcohol extract on the collagen synthesis in rat lungs exposed to silica and the influence on antioxidase activities, level of lipid peroxidation.

目的：探讨手掌参醇提物(Gymnadenia conopsea alcohol extract， GcAE)对染矽尘大鼠胶原合成的干预作用及其对脂质过氧化(lipid peroxidation， LPO)水平、抗氧化物酶活性的影响。

Four weeks after operation, a large quantity of rosy newly formed bone and green bone trabecula were showed in the BG-COL-PS-HYA group. At week 12, scaffold materials was substituted by new bone tissues basically, and Haversian system was visible. Eight weeks after operation, the results of X-ray film revealed that cortical bone was fully connected.

生物活性玻璃/胶原蛋白/透明质酸/磷酸丝氨酸组术后4周硬组织切片可见大量玫瑰红色新骨和绿色骨小梁形成，术后12周支架已基本由新生骨组织替代，哈弗系统形成；术后8周X射线显示骨皮质连接完整，12周缺损完全修复，髓腔基本再通。

AIM: To investigate the level of endogenous hyaluronic acid and its effect on collagen synthesis in composite skin.

目的：了解复合皮组织中内源性透明质酸水平及其对胶原合成的影响。

It has the advantage of a longer duration of efficacy compared with injection of hyaluronic acid and collagen that are absorbed into the body.

这样做的好处是时间较长的疗效与注射透明质酸和胶原蛋白的吸收到体内。

X-ray examination demonstrated that at 4 weeks after implantation, some or even lateral intertransverse bridging regions were unclear, and material density in the repairing group was lower than control group; at 8 weeks after implantation, interspace between up and down bridging was shrunk, and a great quantity of calluses were successively formed; at 12 weeks after implantation, complete confluence was observed, and the density in the repairing group was closed to that in the control group.

结果：采用脱蛋白处理后的松质骨可见大小不等、相互交通、开放孔隙的网架结构，孔径200~500 μm，孔隙率60%左右，其无机成分为羟基磷灰石，有机成分为胶原，力学性能保存良好，细胞相容性良好。X射线片结果显示：植入第4周，横突桥接处部分区域模糊，以内侧明显，此时修复组材料密度略低于对照组；第8周上下桥接部间隙变小，大量连续骨痂生成；12周后完全融合，两组材料密度接近。

Ten rats in each group were randomly sacrificed 14 and 28 days after intratracheal instillation.

结果 观察28天后，对照组：动物体重增加71%（ P ＜0.05），肺胶原蛋白含量提高17.7%（ P ＜0.05），过氧化脂质含量提高1.86倍（ P ＜0.05），羟脯氨酸含量提高24.01%（ P ＜0.05）。

In the rabbits, every Nd: YAG laser iridotomy smaller than 200μm and argon laser iridotomy, Nd: YAG laser combined with argon laser iridoto- my smaller than 450μm closed by the first postoperative week. The mecha- nism for iridotomy closure was assumed to be iris pigment epithelial prolifera- tion, migration and the reformation of stromal connective tissue once the pos- terior pigmented cells have initially bridged the iridotomy.

四、兔眼虹膜激光损伤后的修复能力较强，小于200μm的Nd：YAG激光孔及小于450μm的氩激光、Nd：YAG激光联合氩激光孔均在术后1周内关闭，前者以基质胶原结缔组织再生较明显，而后者以色素上皮增殖、迁移为著。

Collagen is the main component of extra-cellular matrix.It is very important to maintain the flexibility of skin and blood vessel,keep hair and nail soft and lustrous,improve the lubricative property of cartilage.

胶原蛋白是细胞外基质的主要成分，对维持皮肤、血管壁弹性，保持毛发、指甲柔软亮泽，提高软骨的润滑性等都有重要作用。

Objective To evaluate potential of collagen sustained release recombinant human bone morphogenic protein-2 (rhBMP-2) composed with coral and bone mesenchymal stem cells in repair of cranial defect aiming to clarify the origin of new bone after defect repair by such tissue-engineered bone.

目的观察以胶原缓释重组人骨形态发生蛋白-2(rhBMP-2)复合骨髓间充质干细胞及珊瑚构建的组织工程骨修复颅骨缺损的能力，明确复合BMSCs的组织工程骨修复颅骨缺损后新骨的来源。

AIM: To examine the role of matrix metalloproteinases expressed by the tartrate-resistant acid phosphatase-positive mononuclear and multinucleated cells in articular cartilage damage.

目的：观察在胶原诱导的C57BL/6小鼠类风湿性关节炎模型中，基质金属蛋白酶-2、9在耐酒石酸盐酸性磷酸酶阳性的单个核及多核细胞中的表达及其在关节软骨损伤中的作用。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
