Kanzawa pointed, the abdominal vertebra BMD of PTH gene individuals in BB genetype is obviously higher than those of Bb and bb genetype,so he considered that the BstBI polymorphism of PTH gene has dependability with BMD while the DraⅡpolymorphism of PTH gene has no dependablity with BMD.3 The polymorphism of estrogen receptor gene and postmenopausal osteoporosisPMOP is a metabolic bone disease existing in post-menopause femmes, as a result of these femmes\' hypofunction of ovary,ESG level drawdown and the disequilibrium of bone couple procedure,the bone resorption of osteoclast exceeds the bone formation of osteoblastic,osteopenia and bone fragility accrescence have developed,then induces fracture and so on.

Kanzawa等研究发现，BB型PTH基因人的腰椎BMD较Bb、bb型显著为高，认为PTH基因BstBⅠ多态性与BMD有相关性；但PTH基因DraⅡ多态性则与BMD无相关性。三雌激素受体基因多态性与绝经后骨质疏松绝经后骨质疏松是指绝经后妇女由于体内卵巢功能低下，雌激素水平低落，骨偶联过程失衡，破骨细胞的骨吸收大于成骨细胞的骨形成作用所导致的骨量减少，骨脆性增加，进而易于发生骨折的代谢性骨疾病。

4DRG was co-culture with sciatic nerve segment in 10鸖 DMEM;the axons were longer and surround the sciatic nerve segment which was regard as anew evidence for chemotropism.

结果：(1)在无血清条件下单独培养的DRG，背根神经节的轴突数目众多，外形纤细弯曲，不成束，并且施万细胞和成纤维细胞稀少，所以可以排除两者对轴突生长的影响，为观察来源于变性坐骨神经段的可溶性因子对轴突生长的作用提供了有利条件；(2)在无血清条件下DRG和变性坐骨神经段联合培养，①先单独培养DRG，4天后待神经元轴突长出，再与坐骨神经段联合培养，观察到神经元的轴突数目减少，外形挺直，部分轴突之间相互粘附成束；②变性坐骨神经段和DRG同时联合培养，神经元的轴突数目明显减少，外形粗壮，轴突之间相互粘附成束；(3)有血清条件下单独培养DRG，轴突数目较多，外形挺直，长短不一，部分神经元的轴突之间相互粘附，施万细胞和成纤维细胞数目众多，观察到的轴突生长情况受到施万细胞和成纤维细胞的直接或者间接的影响。

The results indicate that, during the early storage period under short time treatment with heat air, the activities of amylase and polygalactouronase are effectively decreased; starch content reduction is inhibited; the degradation speed of pectin and the decrease speed of flesh hardness are slowed down, and the release rate of ethylene in fruit is decreased. During the later storage period, the decomposition rate of middle lamella and primary wall of the Li jujube fruit treated with heat air for a short time is delayed, exosmosis of cell contents is inhibited, and the cell structure is protected, so the storage time of Li jujube fruit is prolonged.

结果表明，梨枣采后贮前短时间热处理能有效地降低早期淀粉酶和多聚半乳糖醛酸酶活性，抑制淀粉水解，延缓果胶降解，降低乙烯释放量，延缓果肉硬度下降速度，后期能延缓果肉细胞中胶层和初生壁分解，阻止细胞内含物外渗，保护细胞的结构，从而延长了贮藏保鲜期。

There were the radicle polarity and the plumule polarity in differentiation of the first somatic embryogenesis.

此外，体细胞胚的发生和分裂是不同步的，往往在同一张切片上既可看到单个的胚性母细胞，又可见到二细胞、四细胞以致多细胞原胚并存的多样化原胚细胞群体。

The podocyte is a highly differentiated interdigitating cell,theist iniury is closely associated with the genesis and development of proteinuria,This article reviews manifestations,mechanism and the treatment of podocyte injury.

足细胞是一种终末分化的多突状细胞，足细胞的损伤与蛋白尿的发生、发展密切相关，现通过对常见足细胞损伤的表现，及针对足细胞损伤的机制和治疗予以综述。

The quantitive value of DNA was 1.82% and 1.92% respectively in nonembryonic cells and the embryonic; during bicellular stage, quadracellular stage and multicellular stage, content of DNA increase slowly, and reach the peak at pear-shap ed embryonic stage keep high level at mature embryonic stage.

非胚性细胞与胚性细胞期的量化值分别为1.82%和1.91%；在二细胞胚、四细胞胚、多细胞胚时期DNA缓慢增长，随着胚性愈伤组织的发育，DNA的含量在梨形胚时期达到高峰；成熟胚的DNA含量虽有所下降，但仍维持较高水平。

The results by invert embedding TEM showed that higher invasive CCL229cells had vast of ER,which distributed throughout cytosol especially largeamount of vesicle-like and flatten cisternal rER in pseudopodia or cell processesand membranous flow-like structure from perinuclear region to pseudopodia,and less Golgi complex.

倒置包埋法常规透射电镜对人大肠癌细胞的超微结构观察结果显示，高侵袭力的CCL229细胞中内质网数量较多并呈全细胞分布，尤其在细胞伸出的众多伪足中含有丰富的小泡状和扁平囊样粗面ER结构，而且观察到由小泡形成的&膜流样&结构从核周一直深入到伪足中，但细胞中高尔基器少见。

Generally we think muscular histogenesis has many steps of biology, including foetal mesoderm merotomy; myoblast shapes in arthromera; myoblast can form muscular tissue to move to limbs; the proliferation of sarcoblast can increase cells\'quatity.

一般认为，肌组织发生是一多步骤的生物学过程，包括胚胎中胚层的分节；成肌细胞在体节形成；成肌细胞向四肢迁移形成肌组织；成肌细胞增殖以增加细胞数量。

The contribution of extracellular radionuclides has not been carried out because it can be calculated and added to the S-values according to conventional MIRD method.

对于多细胞群中的某个细胞，吸收剂量的贡献剂量主要包括靶细胞自身的放射源和周围细胞内的放射源。细胞间质中的放射源和光子的剂量贡献可以用MIRD方法计算。

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。
