The present paper report the karyotype of four nemerteans and nuclear DNA content s of eight nemerteans.

本文研究了4种纽虫的核型和8种纽虫的核DNA 含量，为纽形动物的细胞遗传学研究提供参考。

The animals were randomly divided into groups as follows: testⅠ: Group S, 20 rats were immobilized by using of flexible wire mesh (5x5mm) bent to bodies, and freed of food and water during the experimental period (8pm-8am).

本研究目的是结扎建立实验性牙周炎动物模型，研究限制性应激与牙周炎之间的关系；在应激基础上给与大鼠尼古丁，探讨应激和吸烟协同作用在牙周炎的发生发展过程中的作用，为进一步阐明牙周炎的发病机制奠定基础。

For example,1889-1890 years, the people studies the diphtheria toxin and the tetanus infection toxins with the immunology technique, using it again later on to study the plant toxin, such as the castor toxin, the croton toxin and snake poison, spider poison within the animal toxins.

例如，1889～1890年，人们用免疫学技术研究白喉毒素和破伤风毒素，随后又用它来研究植物毒素，如蓖麻毒素、巴豆毒素和动物毒素中的蛇毒、蜘蛛毒。

A research team at the Johns Hopkins University School of Medicine trained baboons and squirrel monkeys to orally self-administer an Adderall-like drug for two to four weeks, and the team found evidence of amphetamine-induced brain damage, specifically, lower levels of dopamine and fewer dopamine transporters on nerve endings in amphetamine-treated primates than in untreated animals.

一个研究小组在约翰霍普金斯大学医学院的训练狒狒和松鼠猴口头自我管理的Adderall等类药物的2到4周，而且该研究小组发现的证据苯丙胺诱导的脑损伤，特别是较低层次的多巴胺多巴胺转运体和减少对神经末梢的安非他明的待遇比未经处理的灵长类动物。

But those previous studies, Liu said, were either very small or were animal studies.

但这些以往的研究，刘建超说，要么很小或动物的研究。

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。

Because in vivo experiment using human vessels is not possible, and postmortem pathological examination of human arteries in vasospasm provides only limited amount of information, a number of animal models of vasospasm have been developed.

由于临床上很难对痉挛的血管进行在体实验研究，人们便设计了多种动物模型来模拟临床征象进行研究。
