Results: The total saponins of Achyranthes Bidentata Blume not only had significantly inhibitive effects on NE-induced vasoconstriction, but also had direct relaxation effect on vascular smooth muscle.

结果：怀牛膝总皂苷不仅对NE引起的血管收缩有显著的抑制作用，而且还有直接舒张血管平滑肌的作用。

Effectiveness of simulated IAG in counteracting vascular structural adaptational changes and the angiotensin Ⅱ receptor Ⅰ protein expression changes induced by simulated weightlessness was investigated.

第五部分研究1h／d STD时的-1G〓重力负荷是否可完全防止模拟失重大鼠脑部及后肢动脉血管组织形态学及血管紧张素Ⅱ1型受体蛋白表达的变化。

Effectiveness of simulated IAG in counteracting vascular structural adaptational changes and the angiotensin Ⅱ receptor 1 expression changes induced by simulated weightlessness This part of the work testified previous morphological results about the vessels obtained in our laboratory using electron microscopy.

每日-G〓暴露1h即可防止模拟失重大鼠动脉血管出现适应性结构重塑本实验电镜观察再次验证了本实验室早先关于模拟失重大鼠脑及后肢动脉血管相反方向结构重塑变化的报道。

Antibodies against col Ⅲ reacted strongly in the entire pterygial stroma. Conclusions Components of ECM are changed in the pterygium: the sub-epithelial connective tissues and vessels are more prominent in the pterygia than in normal conjunctiva tissues, and abnormal fibers are visible only in the deeper subepithelial connective tissues. This study documents the overexpression of LN and col Ⅲ. They may play roles in cellular adherency, migration and angiogenesis. Also this study documents the overexpression of MMP3 which may degrade ECM in the pathogenesis of the pterygium.

结论翼状胬肉组织中ECM的成分较正常球结膜发生改变，有大量的弹性纤维变性、胶原纤维增生及新生血管形成；col Ⅲ在翼状胬肉组织中表达增加，LN及胶原纤维可能对翼状胬肉中血管形成、细胞粘附和迁移及ECM重建起作用；MMP-3在翼状胬肉组织中表达增加，其对ECM成分的降解作用可能有助于翼状胬肉的形成和向角膜中央侵袭。

From the results obtained, it is concluded that agmatine differentially affects the vascular tone in the femoral, renal, and mesenteric vascular beds.

根据上述结果得出的结论是， AGM对后肢，肾脏和肠系膜血管床的血管紧张性具有不同的作用。

In 66 anaesthetized rats, the effects of local injection of agmatine on femoral, renal, and mesenteric vascular beds were investigated respectively by constant flow perfusion method.

在66只麻醉大鼠，分别采用后肢、肾脏和肠系膜动脉在体恒流灌注法，观察了向灌流环路中直接注射胍丁胺(agmatine， AGM)的血管效应，以所引起的灌流压增减反映血管的收缩和舒张。

The characters of the composition, which is double component sealant made from 1-3% alginic acid sodium and 20% CaCl2 solution, is best in the biological experiment. Before new medical glue appeared in clinical, this gel is hopeful to be applied in clinic and provide theory basis for clinical anastomosis.

质量分数为1%~3%的海藻酸钠水溶液与质量分数为20%的CaCl2组成的双组分密封胶，生物实验中各项性能良好，在新的医用胶面世以前，可以作为血管粘接吻合密封剂，有望在临床中实验推广，为临床血管粘接吻合应用提供理论依据。

门静脉血管造影在肝移植后门静脉并发症诊断中有重要的作用，经皮血管成形术对治疗门静脉狭窄可取得较好的疗效

Stenoses, and ealuation of carotid disease in patients with arrhythmias, alular heart disease, or cardiomyopathy.

由于CTA依靠造影剂灌注识别狭窄的血管腔病变，很少由于血流紊流和动脉扭曲而过高估计血管狭窄。

The detection of blood flow velocity can help diagnose vascular diseases such as angiosclerosis , angiostenosis or angiemphraxis.

血液流速的检测有助于诊断血管硬化、狭窄或阻塞等血管类疾病。

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。
