同种

At the beginning, HLA class I/peptide complex teramer was prepared, including the most frequent alleles in Chinese, i.e., HLA-A2 and HLA-A24. Then the aAPCs were assembled by coating a cell-sized bead with pMHC and anti-CD28 antibody, which were able to provide the dual signals required for T cell activation, and used as stimulator to generate pMHC-specific CTL by co-culture with allogeneic peripheral blood lymphocyte.

首先制备包括我国人群基因频率最高的HLA-A2，HLA-A24的HLA/抗原肽四聚体，在此基础上，制备能够为T细胞提供第一、第二活化信号的aAPC，其表面包被的HLA/抗原肽复合物容易控制，用于诱导同种个体的T细胞产生同种CTL。

Rat model of cryopreserved aortic and pulmonary valved homograft heterotopic transplantation was established to observe the changes of humoral and cellular immunological response and pathological changes of implanted homografts.

方 法 通过低温保存的大鼠同种异体带瓣主动脉和肺动脉异位移植的动物模型，观察同种移植后宿主体液和细胞免疫指标的变化，以及移植物的病理改变。

With the establishment of animal models of aortic homograft transplantation, using immunohistochemical staining, the difference of the expression of MHC Ⅰ antigen and MHC Ⅱ antigen was detected between fresh aortic homografts and cryopreserved ao rtic homografts.

建立大鼠同种异体主动脉移植模型，采用免疫组织化学实验研究新鲜主动脉和低温保存的主动脉同种异体移植后MHC Ⅰ类抗原和MHCⅡ类抗原表达的区别。

Methods Cell viability of the stented homograft valve preserved in liquid nitrogen after 3 months of preservation （experimental group,n = 6） was examined using flow cytometer.

制作同种带支架瓣膜经液氮保存3个月后，利用流式细胞仪技术定量检测瓣叶细胞活性（实验组，n=6），采集新鲜同种瓣膜作为对照（对照组，n=6）。

In the majority of cases, multiple clones from individuals resolved as monophyletic, which suggests that different copies of ITS not completely synchronized evolution, the same species of plant palm plants ITS sequences, sometimes far greater than differences between species of palm plants, However, the high levels of homoplasy in the ITS dataset, led to concerns that topologies obtained from these data might be unreliable; 2 Determination of the original 11 categories of Chinese palm plants matK sequences, and comparison with other 8 Chinese palm matK sequence from the NCBI GenBank database.

结果表明：部分棕榈科植物ITS序列种内差异较大，提示其不同ITS拷贝间没有完全实现同步进化，同种棕榈科植物植物ITS序列差异，有时候大于非同种棕榈植物间差异，这种情况下，由ITS序列构建的棕榈科植物系统树可能是不可信的； 2测定了11种中国原生棕榈科植物matK序列，并通过NCBI网站对GenBank数据库检索得到了其它8种中国原生棕榈科植物matK序列。

Methods The ventral heterotopic cardiac transplantation models were divided into three groups: rejection group, treated group, isograft group, each group with 20 recipients.

采用小鼠腹部心脏移植模型，分为同种异体移植组、同种异体移植+免疫抑制处理组和同系移植组，每组20对。

Methods Thirty SD rats and 60 Wistar rats were randomly divided into isograft group as control (donors and recipients were both Wistar rats) and allograft group (the SD rats as donors, Wistar rats as recipients).

将SD大鼠和Wistar大鼠随机分为同种同基因组和同种异基因移植组。

Analysis of the obtained genome amplification showed that DNA after PCR presented obvious polymorphism, and the results were the same using the same primer to amplify the larva and imago of the same species. It indicates that RAPD technique can be applied to the identification of dry samples and dipped larva sample of longicorn beetles as well as the research of phylogeny. These three methods for extracting genome DNA from different species of longicorn beetles at different preserved time are feasible.

对所获得的基因组扩增分析表明，经过PCR之后的DNA能呈现明显的多态性，同种天牛用同一引物扩增幼虫和成虫所获得的结果相同，可以认为，RAPD技术可以应用于天牛成虫干标本及幼虫浸渍标本的鉴定及系统发育研究中，也证明了这3种方法用于提取不同保存时间、不同种天牛基因组的DNA是切实可行的。

Gross observation and mass changes of the grafts: Two weeks after inoculation, there were obvious nod formations at the inoculated sites, but no nod formed in the blank control group.

移植物的大体观察与质量变化：接种2周后，同种异体软骨细胞-FasL组及同种异体软骨细胞组兔接种细胞-材料复合物处，均有明显的结节形成，对照组未形成接节。

We also found that the same species living in different locations showed markedly different phenology, which was related to the different climate regimes.

8部分引种在西双版纳热带植物园的不同来源的同种植物之间存在明显的物候差异；不同地方生长的同种植物物候期也存在明显的差异，其差异和气候空间差异有很大关系。

Plunder melds and run with this jewel!

掠夺melds和运行与此宝石！

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
