查询词典 rat terrier

The results showed that (1) all the arteries tested had tachyphylaxis to peptidergic agonists;(2) the desensitization of the arteries tested to catecholamines was uneasy except BA;(3) the desensitizations to AⅡ, AVP and PE were homologous;(4) the endothelium-EDRF -cGMP pathway had no contribution to the tachyphylaxis of PA to AⅡ and AVP;(5) membrane receptor cycling (internaliation and re-insertion) contributed only in part to homologous desensitization;(6) there was no change in the function of voltage-dependent Ca〓 channel during desensitization to AⅡ and AVP;(7) some changes in G protein occurred during homologous desensitization;(8) the most surprising finding was that the caudal arterial smooth muscle of stroke-prone spontaneously hypertensive rat showed tachyphylaxis to α〓-adrenoceptor agonist PE, while the tachyphylaxis of pulmonary artery of SHR was not changed compared with that of Wistar rat.

脱敏是消除效应的一种有效方式。因此，研究不同血管对不同激动剂脱敏的差异及阐明脱敏的机制，有助于阐明血管活动个性化的机制。研究表明：血管对肽类激动剂的脱敏方式为快速脱敏，而对儿茶酚胺类激动剂不易脱敏；血管对肽类激动剂和儿茶酚胺类激动剂表现为同源脱敏；内皮-NO-cGMP通路不参与肺动脉对AⅡ和AVP的快速脱敏；用PAO抑制膜受体的内在化只能短暂抑制脱敏的发展，提示用膜受体数目的下调说不能完全解释同源脱敏；血管对AⅡ和AVP脱敏后VSMC细胞膜电压依赖性钙通道功能无改变；CA对AVP脱敏后GTPγS的量-效曲线下移，说明有G蛋白的变化，但这种变化并非G蛋白的亲和性改变；SHRsp之CA平滑肌对AⅡ和AVP的快速脱敏并未减弱，但对PE却表现为快速脱敏，这是我们首次发现的一个非常有趣的现象。

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。

Resultsthe yuegan capsule increased the activity of sdh, g 6 pase and the amount of hepatic glycogen, and restrain the activity of acpase, and could improve the changes of rat hepatocytes structure.conclusionyuegan capsule has protective effects on ccl4 induced injury of primary cultured rat hepatocytes.

The moral of the story is: Since the time of our birth, tribulation has been chasing us like a hungry tiger and death has been waiting like a fierce lion at the bottom of a cliff. And the alternation of day and night is like a black rat and a white rat who keep biting into the tree of our lives.

这个故事的寓意是：从我们诞生的那一刻开始，苦难，就像饥饿的老虎一直追赶着我们；死亡，就像一头凶猛的狮子，一直在悬崖的尽头等待；而白天和黑夜的交替，就像一黑一白两只老鼠，不停地咬着我们暂时栖身的生活之树。
