Methods 36 rabbits were made deficit in their knee joints and then they were randomly divided into autogenous osteiochondral mosaicplasty compound factor gelatum group, antogenous osteiochondral mosaicplasty group, and periosteum reimplantation group and control group.

方法将36只健康家兔膝关节造成实验性缺损，随机将动物分成自体骨软骨镶嵌移植联合凝胶生长因子复合体组、自体骨软骨镶嵌移植组、骨膜移植组和空白对照组。4、8、12周后对修复组织进行形态学观察及组织学检查。

Mainly the production of plastic bags: PE, PP, OPP, PO, PVC flat pockets, side seal bags,±BAG, BAG steam beads, organ bags, bone BAG, Shrink BAG, such as a wide range of printed plastic bags.

胶袋部主要生产：PE、PP、OPP、PO、PVC平口袋、边封袋、斜挂袋、汽珠袋、风琴袋、骨袋、收缩袋等各种印刷胶袋。

After 24 weeks,the operation area of group A was more smooth,and the surrounding normal cartilage naturally straight flush,transparent form new cartilage,subchondral bone formation in good condition;Group B restoration surgery the basic integrity of the cartilage tissue, center is not yet fully integrated,there was slight depression;CollagenⅡimmunohistochemistry of cartilage that was new brown area.Group C has no formation of articular cartilage.The growth and the intergration of subchondral bone of group A and B were better.

术后24周取材，见A组山羊手术区关节表面较为光滑，与周边正常软骨自然连续平齐，透明的新生软骨组织形成，软骨下骨形成完好；B组山羊手术区修复的软骨组织基本完整，中心部位仍未完全融合，有微小凹陷；Ⅱ型胶原免疫组化示新生软骨组织呈棕黄色。C组术区关节凹陷，无关节软骨组织形成。A组和B组，软骨下骨的生长及与周围组织的结合均较好，无植入物脱落现象的发生。

The effects of BMP-2, TNF-α and they two synergism in different concentration were also detected. The mRNA expression of cbfal, OC, H-ras, BMPR-IA, type Ⅰ and typy Ⅱ collagen of ligamental fibroblast under the co-stimulation of BMP-2 and TNF-α were detected using RT-PCR technique.

并分析了不同浓度的人重组骨形态发生蛋白-2（rhBMP-2，10ng/ml、100ng/ml、250ng/ml、500ng/ml）和人重组肿瘤坏死因子-α（rhTNF-α，5u/ml、50u/ml、100u/ml、500u/ml）及两者协同作用（500ng/ml rhBMP-2+50u/ml rhTNF-α）对两类细胞系分化方向（细胞形态变化、ALP活性、DNA及胶原合成、骨钙素分泌）的作用。

Aminoguanidine could not effectively prevent bone mass loss of diabetic rats.

但由于AGE对Ⅰ型胶原的修饰，使其在骨吸收中对蛋白酶水解产生高度抵抗，PTH不能充分发挥骨吸收作用。

The methodology and its mechanism for the biomimetic synthesis of HAp/Col bone-like composite by in vitro imitating bone biomineralization and self-assemble process of materials is reviewed here. hydroxyapatite/collagen ; bonelike composite ; biomineralization ; self-assembly

从成分上来讲，天然骨除了含有羟基磷灰石无机成分外，还含有胶原(collagen，Col)、糖蛋白、糖胺聚糖等少量的有机成分无机物与有机物含量之比约为7∶3，其中胶原占有机质重量的90%犤2

Methods:The cattle cancellus bone were degreased,deproteined and calcined to form TBC vector.After the surface was covered with collagen.the cultured rabbit osteoblasts were compounded to TBC in vitro.5,10 and 20 day later,the compound materials were observed under scanning electron microscorpe.

牛松质骨经脱脂、脱蛋白、煅烧等工艺制成煅烧骨作为载体，载体表面经胶原处理后将体外培养的兔骨膜成骨细胞复合到TBC，分别于5日，10日和20日取材，行扫描电镜观察，设对照组。

Methods: Absorbable collagenic membrances and bone powder were applicated in 35 implantation cases, and the efficiency of induction bone tissue regeneration was evaluated.

选择35例在种植手术时，种植体周围骨量不足的患者，采用可吸收胶原膜和骨粉行诱导骨组织再生，观察其促进颌骨再生和种植体骨整合的临床效果。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
