Neuropeptide Y, neurotensin, which is in antagonism, are released from platelet and participate in pathological reaction mainly in vasoconstrictive action in the pathologic process of ischemic cerebrovascular disease.

NPY与NT在ICVD病理过程中，由血小板大量释放并积极参与了以缩血管效应为主的病理反应，是造成血栓形成、局部血管痉挛的重要病理因素。

This process includes: platelet aggregation, sticking to damaged blood vessels, releasing vasoconstrictive agonists, activating or binding coagulation agents, and releasing platelet-derived growth factor and platelet factor IV.

该过程包括：血小板聚集，黏附于受损血管，释放血管收缩因子，激活或结合于凝固因子，最后释放血小板源性生长因子和血小板因子Ⅳ。

Excessive neural input does not mediate diminished vasoconstrictive responses in the ACL transected knee; inflammatory mediators may play a role in the deficient vascular responsiveness of the ACL transected knee.

过量的神经输入没有能够调节前交叉韧带切除了的膝关节的血管收缩应答反应；炎症调节因子可能在前交叉韧带切除的膝关节血管应答不良中期重要作用。

The vasodilating mechanism of AE from CM ma he related to promoting the release of NO from endothelium of blood vessel and synthesis of NOS and NOS in aortic tissue.

桑白皮丙酮提取物的舒张血管作用机制可能与血管释放NO和促进cNOS、NOS合成有关。

Carvedilol, a non-cardioselective vasodilating BB is more effective in reducing portal pressure than propranolol, but to date there have been no clinical studies assessing the efficacy of carvedilol in primary prophylaxis.

与心得安相比，卡维地洛，这种非心脏选择性扩张血管的BB，能更有效的降低血管入口处的压力，但至今尚没有临床研究对卡维地洛的主要预防作用进行评估。

At present the main treatment is to increase endurance, and actively prevent and treat lung infection, and control fibrosis drug use, such as penicillamine, colchicine, azathioprine, and so on, can also be supplemented by anti-vascular inflammatory drugs, such as low-dose glucocorticoids , vasodilating agents, such as anticoagulants.

目前治疗主要是提高抵抗力，积极防治肺部感染，同时用控制纤维化的药物，如青霉胺、秋水仙碱、硫唑嘌呤等，也可辅以抗血管炎症药物，如小剂量糖皮质激素、扩血管剂、抗凝剂等。

METHODS: Differences of the vasodilating action of Ipt in big artery and small artery were studied using isolated rat tai l artery helical strips and aortic rings, and the effects of Ipt on potassium cu rrents in smooth muscle cells derived from rat tail artery were observed by usin g patch clamp technique.

采用大鼠尾动脉螺旋状血管条和主动脉离体血管环两种组织，对比观察盐酸埃他卡林对大、小动脉扩张作用的药理学特性，并且利用膜片钳技术观察盐酸埃他卡林对大鼠尾动脉平滑肌细胞钾电流的影响。

Results AE from CM had vasodilating effect on the contracti on of mesentery blood capillary in guinea pigs and the contraction of rat thoracic aortic ring induced by l0μmol/L phenylephrine, even under the condition of pre-treating with glibenclamide (1μmol/L) or propranolol (3μmol/L). When the endothelium of the rat thoracic aortic ring was removed, AE from CM had not vasodilating effect hut constrictive effect. AE from CM could also increase the contents of NO, NOS and cNOS in the aortic tissue and had no obvious effect on the NO content in plasma and iNOS in aortic tissue of rats.

结果 桑白皮丙酮提取物有抑制去甲肾上腺素收缩豚鼠肠系膜微血管的作用，抑制苯肾上腺素(10μmol/L)收缩离体大鼠胸主动脉环的作用，预加优降糖或普蔡洛尔(3μmol／L)后仍然有松弛作用；大鼠胸主动脉环去内皮后药物无松弛作用，反而起收缩作用；显著升高血管的NO和NOS、cNOS含量，对大鼠血浆的NO和血管iNOS的含量影响不大。

Endothelium-derived nitric oxide plays an important role in the regulation of vasomotion and the balance between thrombosis and thrombolysis.

血管内皮细胞产生的一氧化氮(nitric oxide，NO)在调节血管舒缩、维持凝血—溶栓平衡方面扮演着重要的角色。

SI can inhibit vasomotion in vaso-dilation status, but its mechanism is not mediated by endogenous NO.

血管运动得以恢复；在SI的有效作用时间内应用L—NMMA则不能使处于舒张状态的血管收缩。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
