血管舒张的

Methods The endothelium-dependent dilation function was measured with high-frequency ultrasound in 61 patients with Takayasu arteritis and 36 normal subjects, the diameter of the brachial arteries before and after reactive hyperemia was also measured.

我们经过4年的观察研究发现多发性大动脉炎对血管内皮舒张功能有更直接的影响，EDD%在此病的观测中具有重要的临床意义。1资料与方法1.1研究对象①大动脉炎组：选择已确诊

This can improve systolic and diastolic function of blood vessels, and promote the re-distribution of blood.

这样的收缩和舒张可以改善血管的功能，促进血液的再分布。

It is an important medium which can dilatate blood vessel, participate in inflammatory reaction , infective immunoregulation activity and nerve conduction.

目的 一氧化氮是近年发现的一个高活性气体信号分子，除舒张血管外还是参与炎症反应、感染性免疫调控活动与神经传导的重要介质。

Previous studies showed that before the pial artery large dilation which were widely observed in CSD, there is also a small constriction occurring in pial arteres.

已有研究表明，在普遍被观察到的CSD过程中软脑膜动脉血管大幅度舒张之前，还存在一个较小幅度的软脑膜动脉扩张和收缩。

We have previously shown that the vasodilator effect of protopine on rabbit aorta is related to the elevations of cAMP and cGMP.

本实验室先前的研究已证实，普罗托品(protopine，Pro)舒张家兔主动脉的作用，可能与其增加血管平滑肌细胞内cAMP和cGMP水平有关。

It has great biologic effect, such as dilating blood vessel, reducing blood pressure, restraining cell s growth and proliferation, and so on.

其生物学效应广泛，有明显的舒张血管、降低血压、抑制细胞生长、增殖等功能，在肾脏功能调节方面起着重要的作用。

Isolated rat pulmonary artery was perfused and the tension of the vessel was measured, the effect of isopropyl 3-(3,4-dihydroxyphenyl)-2-hydroxypropanoate on the pulmonary artery precontracted by noradrenaline and concentration-response curves of 5-hydroxytryptamine(5-HT), endothelin-1(ET-1), U46619 and KCl was also observed.

制备大鼠肺动脉条，采用离体血管灌流方法，观察丹参素异丙酯对去甲肾上腺素预收缩动脉的舒张作用以及对多种血管收缩药量效曲线的影响。

ConclusionG-Rb has protective effects on ventricular remodeling through improving systolic and diastolic function of cor sinistrum in ventricular remodeling rats,increasing anti-oxidase activity, reducing the damage of free radicals and vasoactive substance in myocardium and correcting disequilibrium of PGI2/TXA2 in ventricular remodeling etc.

结论G-Rb对大鼠心室重构具有保护作用，可能与其改善心室重构大鼠的左心收缩和舒张功能，增强抗氧化酶活性，减少自由基及缩血管活性物质对心肌的损伤，纠正PGI2/TXA2失衡等机制有关。

The relaxing responses of renal arteries to DA receptor agonists may be related to the change of cAMP content.

DA1受体激动剂对肾血管的舒张反应可能与cAMP生成量的变化有着密切关系。

Methods The changes of contents of AGEs in plasma and the abdominal aorta and changes of VSMC of the abdominal aorta were investigated with methods of fluorospectrophotometry, immunohistochemistry, computer image analysis and transmission electron microscopy on streptozotocin-induced diabetic rats. Results From the fourth week, in diabetic rats, the contents of AGEs in plasma and the abdominal aorta increased, the relative area of α-SM-actin in the abdominal aorta decreased, the density of nucleus of VSMC increased, and mitochondria and rough endoplasmic reticules in VSMC increased.

后者在早期主要是血管平滑肌细胞(vascular smooth muscle cell， VSMC)和胶原纤维增多，弹性纤维减少，动脉增厚等，引起动脉的顺应性降低，舒张功能减弱［1～3］；晚期主要表现为动脉粥样硬化和动脉硬化，其中以VSMC的增生和迁移较为突出，其表型也由收缩型转化为合成型［4，5］。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
