NE, 5-HT or a GABA〓 receptor agonist muscimol using behavioural method.

在第二系列的实验中，我们使用行为测痛的方法观察了鞘内注入非竞争性〓受体阻断剂印防已毒素和竞争性〓受体阻断剂荷包牡丹碱，对鞘内注入NE、5-HT和〓受体激动剂muscimol所引起的镇痛作用的影响。

This suggested that the mechanism of alleviating asthma was that when drugs were combined with the active part ofβ2 receptor ,the conformation of receptor was changed and receptor was activated,spasm of bronchial smooth muscle was alleviated,of which relieved edema of air passage、restrained inflammatory cell and so on,these would contribute to pursiness.

这表明，麻杏石甘汤的平喘机制应该是通过和β2受体活性部位结合，改变了受体的构象，受体被激活，使得支气管平滑肌松弛，减轻了气道水肿，抑制了炎症细胞等，有利于缓解和消除喘息。

C The cDNA sequence of GnRH receptor in submaxillary is identical to the relative sequence of GnRH receptor in pituitary, but whether the entire sequence of GnRH receptor are identical between two organs should be further studied.

颌下腺GnRH受体cDNA序列和大鼠脑垂体的GnRH受体的相应片段相同，但全长序列是否相同，尚无定论。4.GnRH具有调节大鼠颌下腺分泌NGF的作用。

Aim: To determine whether activation of κ-opioid receptor with U50,4 88 H, a selective κ-opioid receptor agonist, produces any changes in electrical u ncoupling during prolonged ischemia and whether these changes in electrical unco upling is associated with the cardioprotection induced by κ-opioid receptor ac tivation, and to explore the possible mechanism.

测量指标：以分光光度计在490nm波长下测定氯化三苯基四氯唑与活细胞反应的产物formazan含量的方法测定心肌细胞活性、测定冠脉流出液中乳酸脱氢酶的含量以及心室内压；②全心停灌70min，应用四电极法观察不同浓度U50，488H、nor-BNI和5-HD对缺血期间心肌整体阻抗和电脱耦联参数(电脱耦联时间、平台时间、电脱耦联最大速率和阻抗倍数)的影响。

In addition, our data indicated that the conformation of NR1 subunit homodimers was affected by the partner NR2 subunits during the formation of heteromeric receptor complexes, which might underlie the mechanism by which NR2 subunits modify NMDA receptor function. We also found that in the endoplasmic reticulum, even the whole extracellular N-terminal domain was truncated, the NR subunit could form homomers or heteromers with each other in HEK293 cells, which indicate that the NT is not the crucial element for the receptor assembly.

同时，通过推算FRmax，我们发现NR亚单位同二聚体的N端构象在形成功能性受体的前后是发生变化的，特别是对于NR1a亚单位，其同二聚体的N端构象会因与其配对的NR2亚单位的不同而发生不同的改变。

The properties of several rhodopsin sequences were analyzed by comparing withα2A-adrenergic receptor, and a great similarity was found between bovine rhodopsin andα2A-adrenergic receptor. Therefore transmembrane helices ofα2A-adrenergic receptor were constructed homologically based on the bovine rhodopsin.In the newly constructed structure, a 0.090 nm3 active-site, which was enclosed by several reported active residues, was found.

通过对比多个与α2A-肾上腺素受体同属G-蛋白偶联受体的视紫红质蛋白序列，选择以相似性最大的牛视紫红质蛋白为模板，同源模建了α2A-肾上腺素受体的跨膜结构，并在结构中找到了体积为0.090 nm3，已被报导的活性残基包围的活性位点。
