同种移植

The goat testes with various size were collected from abattoir and to carry out injection test.

本试验对屠宰场收集到的不同体积的山羊睾丸进行了注射实验，为将来活体同种移植山羊精原干细胞建立有效的移植方法。

Before long it developed into two more complicated forms: homograft and heterograft .

不久，自体移植术又发展为两种较复杂的形式：同种移植术和异体移植术。

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。

Methods: The fetuses of interfamily pregnancy day 4, day 8 and day 12 were acted as experimental group, while the ones of intraspecific pregnancy day 4, day 8 and day 12 of embryo transfer and the uteri of pseudopregnant mice of corresponding time were employed as positive and negative groups respectively.

以科间妊娠第4天、第8天、第12天的孕体为实验组，小鼠同种移植妊娠第4天、第8天、第12天的子宫孕体和相应时间假孕小鼠的子宫为阳性和阴性对照。

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。

Discussion TNF-αis an inflammatory cell cytokine,with the properties of autocrine, produced by cadiocyte at the early age of MIRI,inducing myocardial function abnormal and cadiocyte necrosis in MIRI、pyaemia、chronic cardiac insufficiency、viral myocarditis and the homograft rejection of heart.

讨论 TNF-α是心肌缺血再灌注早期心肌细胞产生的炎性细胞因子，是一种自分泌的作用因子，在缺血再灌注损伤、脓毒症、慢性心功能不全、病毒性心肌炎以及心脏同种移植排斥反应中均能导致心肌功能能障碍和心肌细胞坏死。

Objective: To investigate the survival time of corneal rejection in allogene mice model and the effects of J2 on prevention of allograft rejection; To determine the effect of J2 on the immunal systems of both normal mice and those after allogeneic corneal transplantation.

目的： 研究同种异基因小鼠角膜移植后植片的生存时间及J2的抗角膜排斥反应的作用；研究J2对正常小鼠及同种异基因角膜移植小鼠的免疫系统的影响，从而探讨新型药物J2对于角膜移植排斥反应的作用机制。

Methods: The fetuses of interfamily pregnancy day 4, day 8 and day 12 were acted as experimental group, while the ones of intraspcific pregnancy day 4, day 8 and day 12 of embryo transfer and the uteri of pseudopregnant mice of corresponding time were employed as positive and negative groups respectively.

以科间妊娠D4、D8、D12的孕体为实验组，小鼠同种移植妊娠D4、D8、D12的子宫孕体和相应时间假孕小鼠的子宫为阳性和阴性对照。

Because of the greater differences between ecies, as o osed to within a ecies, these tra lants have the least chance of working.

和同种移植不同的是，异种之间存在很大差异，从而使得这种移植成功的可能性很小。

In our research,Wistar rats and SD rats which were parathyroidectomized were used as donors and recepients respectively.The parathyroid gland of the Wistar rat were allografted into the cerebroventricle and other different sites of the brains in SD rat s tereotaxically. Using methods of testing serum Ca~(2+) concentration,histological examination,histochemical and immunocytochemical methods and electron microscopic observation,we investigated the survival of the grafting tissue,its revascularization, infiltrating of monocytes, changes of microglia and astrocytes, the relationship of the CNS with the immune system, and the mechanism of rejection were investigated.The results as following: I .Effects on PTG after allografting into cerebroventricle and cerebral parenchyma of the brain: Testing serum Ca~(2+) conc.

本研究以Wistar大鼠作为供体，切除甲状旁腺的SD大鼠作为受体，在立体定位下将同种异体的PTG移植到大脑的不同部位，设计了侧脑室-内分泌系统移植的代替途径，比较了侧脑室内移植和脑实质内移植的异同，通过测定血清Ca~(2+)的浓度、组织学检查、组织化学和免疫细胞化学以及电镜观察对移植后PTG组织的存活、血管的再生、单核细胞的浸润、CNS内胶质细胞的变化、对免疫系统的影响及免疫排斥的机制进行了研究，结果如下：一、同种异体PTG侧脑室内移植与脑实质内移植的比较：血清Ca~(2+)的检查发现，PTG侧脑室内移植后第7天，血清Ca~(2+)的浓度恢复到8mg％以上，一直持续到移植后第8-12周；移植后第12周仍有60％移植PTG的动物血清Ca~(2+)维持在正常水平。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
