The histiological characteristcs, and activities of alkine phosphatase and acid phosphatase of the implantan were examined to study the effects of fluoride on biological activities of BMP.

结果 氟对BMP的生物活性有直接的影响，氟能促进BMP将更多的成纤维细胞转化为成骨细胞，并能增强成骨细胞的功能，加速钙盐沉积，而破骨细胞功能有所下降。

The protoxylem vessels initiated lignification in the early stage of vascular bundle differentiation, whereas metaxylem vessels and fiber walls started lignification from the middle lamella and cell comers after completion of vascular bundle differentiation. The walls of most parenchyma cells lignified after the stem reached its full height, while a few parenchyma cells remained non-lignified even the culm is 7 years old.

研究结果表明：毛竹茎的原生木质部导管在维管束发育早期就已木质化；后生木质部导管和纤维细胞在维管束分化完成后，自胞间层和细胞角隅处开始木质化；基本薄壁组织细胞木质化的发生较晚，通常在茎的节间完成伸长生长后才开始，但也有少数薄壁组织细胞始终保持非木质化的薄壁状态。

The surface antigen expressions of MNC were detected by flow cytometry. MNC were induced with DMEM medium, containing HGF alone, FGF4 alone, HGF+FGF4 or no growth factor, respectively. The markers of hepatic linear cells were examined before induction, and 7, 14, 21 and 28 d after induction by RT-PCR, immunocytochemistry and periodic acid-schiff in every group.

To study the effect of basic fibroblast growth factor and nerve growth factor on immune function in mice. Methods: Through the assays of Phagocyte, PFC, MTT and ELISA, the action of Mφ, B lymphocyte and T lymphocyte of mice was observed.

细胞生长因子是多功能的生物活性多肽，包括成纤维细胞生长因子、神经生长因子和表皮生长因子等，作为在细胞间传递信息的物质，细胞生长因子在机体内发挥着极其广泛的生物学作用，参与多种病理生理过程，如生长、免疫、肿瘤、创伤愈合等。

To explore the potential mechanism of cigarette smoke extract -induced cell injury, primary cultured skin keratinocytes and fibroblasts from rat were selected as target cells in Part Ⅰ study compared with the effect of UVA.

本研究第一部分以原代培养的大鼠皮肤角质形成细胞和成纤维细胞为对象，采用UVA损伤作用为参照，探索香烟雾提取物（Cigarette SmokeExtract，CSE）对皮肤细胞的损伤作用，重点观察CSE所致的皮肤细胞毒作用、功能损伤及可能作用机制。

One eye in patients was selected to do the tear film breakup time, Schirmer test and cornea fluorescein staining, and the expression of NFκB and TGFβ1 on bulbar conjunctiva endepidermis was detected by immunohistochemistry.

TGFβ1是多功能细胞因子，对上皮细胞具有较明显的抑制作用，对成纤维细胞及其他间叶组织来源的细胞均具有明显的刺激作用，表现为胶原合成增加，有利于组织修复及伤口愈合［3，4］。

Results In animal study, lumbricus could inhibit the growth of staphylococci, bacillus coli and bacillus aeruginosus. The time of wound healing in experimental group was 4 days shorter than that in control group. At 4d and 7 day the numbers of the capillary, blood vessel endodermis and desmohemoblast desmocyte and splitting epithelium of trial group were much more than those of control group. At 4d the trial group′s numbers of splitting mesenchymal cell were much more than that of control group. From 3d on the wound healing and granulation filling of experimental group were much quicker than those of control group.

结果 动物实验中，地龙能抑制金黄色葡萄球菌、大肠杆菌及绿脓杆菌的生长；实验组创面愈合时间较对照组提前了4天；第4、7天实验组动物创面的毛细血管数、血管腔内皮细胞数及间质成纤维细胞数均较对照组明显增多，上皮细胞分裂象也高于对照组，第4天的间皮细胞分裂象也高于对照组；自第3天始创面愈合及肉芽充填速度实验组明显快于对照组。

This pattern is characterized by the combination of pro-MMP-2 and membrane type 1 (MT1)-MMP expression, which drie pericellular generation of actie MMP-2 and local degradation of normal lier matrix. In addition there is a marked increase in expression of TIMP-1 leading to a more global inhibition of degradation of fibrillar lier collagens by interstitial collagenases (MMP-1/MMP-13). These pathways play a significant role in the progression of lier fibrosis.

其降解肝正常基质，同时抑制引起肝纤维化的纤维胶原降解，这种情况的特点是前明胶酶A合成和膜型1－MMP表达，使得小叶内细胞激活MMP-2和降解当处的正常肝基质，此外血浆1型组织基质金属蛋白酶抑制剂（TIMP-1）明显升高引起广泛的抑制间隙胶原酶(MMP-1/MMP-13)对纤维肝脏胶原的降解。

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.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
