异种性

Chicken and quail intergeneric hybridization is a classic distant hybridization in fowl. In fowl science, chicken and quail belong to Aves, Galliformes, Phasiamidae, Gallus and Coturnix, and this hybridization combination has become the example of researching the incompatibility of different germ cell and sterile of distant hybridization.

鸡与鹌鹑杂交是属间杂交，其杂交种胚胎早期出现大量的死亡，并且杂交种出壳以前雌性胚胎全部死亡，这使鸡与鹌鹑杂交成为研究异种生殖细胞不亲和性和杂交种不育的典型。

RESULTS ① rhBMP2/BCB used alone was capable of healing the defect in large part by 16 wk, with a similar repair process and mechanism to that seen with RBX;② use of rhBMP2/BCB in conjunction with vascularized periosteal graft exhibited stronger defect-repairing power, basically healing the defect by 8 wk. The repair process consisted of intramembranous and endochondral ossification that resembled the physiological repair during the fracture healing.

结果①单纯rhBMP2/BCB移植，可在16 wk使节段性骨缺损基本修复，其机制与过程与重组合异种骨相似；②rhBMP2/BCB与带血循骨膜联合移植，仅用8 wk即可修复骨缺损，其修复机制与骨折修复相仿，包括膜内成骨和软骨成骨两种机制。

After oral administration (0.50 mg*kg-1) of cetirizine,the rat homologous passive cutaneous anaphylaxis and mice auricle isologous passive cutaneous anaphylaxis were reduced significantly.

Objective To study the efficacy of combined use of rhBMP2/BCBand free periosteal graft in repairing segmental bony defects.

目的 探讨复合基因重组人BMP2(rhBMP2)的异种骨与游离骨膜联合移植修复节段性骨缺损的效果。

This paper analyses the weldable characteristics between congeneric metals and heterogeneous matals in details,aiming at the choice for electric locomotive air pipeline material.

针对电力机车空气管道材质的选择问题，详细分析了一些常用同种金属材料和异种金属材料的可焊性，并根据应用经验提出选材参考对象。

AIM To analyse the components of antigen-eliminated massive bovine cancellous bone and to study the mechanism of high concn H2O2 eliminating the antigenicity of xenogenic bone.

目的研究大块牛松质骨处理后的各种成分及高浓度H2O2消除异种骨抗原性的机制。

However, the specification has some limitations on the object identifying and binding mechanism, and these limitations make it difficult to provide portability of applications and interoperability of interworking systems.

然而规范中异种对象的标识及绑定机制存在问题，影响了应用程序的可移植性和互操作系统之间的互操作性。

Objective To establish a simple pig-to-monkey xenograft model to study delayed xenograft rejection.

目的 建立一个简便的研究延迟性排斥反应的猪—猴异种心脏移植模型。

To provide basic parameters of evaluating the biological safety of xenotransplantation from pig to human, ear tissues from 31 individuals were randomly collected from a Shazi Ling pig population. PCR and RT-PCR were performed to detect porcine endogenous retrovirus proviral DNA and mRNA respectively. The sensitivity of the PCR was evaluated using a positive control.

为评价从猪到人异种移植的生物安全性提供依据，从湖南沙子岭猪的保种群内随机采集31头个体的耳样组织，应用PCR和RT-PCR技术分别检测这些组织中内源性逆转录病毒（porcine endogenous retrovirus，PERV）的前病毒DNA和mRNA，并对PCR扩增的灵敏性进行评估。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
