收缩血管的

The first part consists of three experiments:(1) The rings were incubated in KH, 20, 50 mmol/L 〓 for 1 house, relaxation in response to the EDHF stimuli A23187 in 30nmol/L U46619-induced preconrtaction in the presence of 7 μ mol/L indomethacin, a cyclooxygenase inhibitor, 300μmol/L LNNA, a nitric oxide biosyhnthesis inhibitor, and 1mmol/L tetraethylammonium , a 〓 blocker, or 3 μmol/L glibenclamide , a 〓 blocker, was compared with the control;(2) After the arteries were incubated in KH, UW solution or HTK solution at 4℃ for 4 hours, endothelium-derived relaxation (percentage of 30nmol/L U46619 precontraction) was induced by A23187 in the present of 7 μmol/L indomethacir and 300μmol/L LNNA;(3) After incubation with KH, UW solution and STH (either at 37℃ in oxygenated organ chamber or at 4℃ in a refrigerator for 4 hours), endothelium-derived relaxation (percentage of 30nmol/L U46619 precontraction) was induced by A23187 in the present of 7 μ mol/L indomethacin and 300 μmol/L LNNA.

第一部分研究结果：（1）单纯浸泡于KH的冠状动脉A23187能引发66.67％的血管舒张反应，经TEA及20mmol／L、50mmol／L钾离子作用后，血管舒张反应程度显著降低，但经GBM作用后改变不明显；（2）与保存于KH的冠状动脉相比，A23187引发的血管舒张反应程度，保存于UW液的明显下降，保存于HTK液的无明显变化；（3）在37℃条件下，血管环浸泡于STH出现缓慢轻微的舒张反应，浸泡于UW液初期出现短暂收缩反应，但此后主要以舒张为主：在37℃条件下，血管经UW液保存后，U46619引发的收缩反应程度降低；不论在37℃或4℃条件下，A23187引发的血管舒张反应，经UW液保存后明显下降，但用STH保存后变化不明显。

Expansion and contraction of blood vessels of normal blood flow is essential.

血管的扩张和收缩对血液的正常的流动是必需的。

Through the expelling of the toxins, illnesses caused by drug abuse are gradually alleviated and finally recovered, evidenced by the improvement of heart function and the increase of exercise stamina, the recovery from stomach ulcer (appetite greatly increased on the 5 th day of treatment and the weight increased by over 5 kg in 20 days), the recovery from constipation, liver pain, hunch back, impotence and menstruate irregularity, shrink pupil, trembling limbs, hardened blood vessels, and the irregular density and color of blood.

The transform of phenotype of VSMC: The mRNA expressions of SM22α-a notate gene of contractile VSM-were all detected on normal aortas,but decreased normally when the aortas were destroyed and cultured in vitro for 10 days,especially in the serum groups,whose SM22αmRNA could not be detected by RT-PCR.Here,BQ123 can increased their expressions.This demonstrated that serum culture and the secretion of ET-1 can produce the transform of phenotype from contractile to synthesize type.

血管平滑肌表型的转化：RT-PCR检测发现，血管平滑肌收缩表型标志基因SM22α在正常血管平滑肌中都有表达，但在内皮损伤后体外培养10天的血管表达明显减弱，其中血清培养组血管基本不表达，加内皮素受体阻断剂BQ123后，各组SM22α的表达均有所上调，这表明内皮素分泌和血清培养促进了血管平滑肌的表型由收缩型向分泌型的转化。

Since the reduced effective volume is due to extreme vasodilation then a vasoconstrictor can be used and the vasoconstrictor for which there is the most experience is Terlipressin.

由于减少的有效血容量起因于血管扩张，血管收缩剂可以用于治疗此病，有效的血管收缩剂是特利加压素。

In the recent 20 years,evidences have proved that endothelial cell barrier function and vascular permeability depend on the endothelial morphologic changes and the formation of intercellular gap. It is thought that change of endothelial contractility is the last congenerous pathway of different signal transduction in permeability changes.

近二十多年来从细胞学水平的研究已证明，内皮细胞形态变化和细胞间缝隙的形成决定了内皮细胞的屏障功能和血管的通透性，内皮细胞收缩性的改变被认为是不同的信号机制导致通透性变化的最后共同通路。

Methods 50 patients with diabetes and contrast group were observed, with transcrianial color Doppler flow imaging, cerebral blood stream velocity; pulsative index,resistive index and S/D were calculated of middle cerebral artery, anterior cerebral artery and posterior cerebral artery Results (1)Changes of cerebral blood stream velocity were non-specifitical in blood waves of TCDFI, but VE was reduced.

经临床诊断糖尿病50例，行TCDFI检测大脑中动脉、大脑前动脉、大脑后动脉等血管的血流速度指标及搏动指数、阻力指数，收缩期血流速度/舒张末期血流速度及频谱形态分析与健康组对照比对分析。结果(1)TCDFI频谱中，血流速度的变化，Vmax是非特异性的，而VE是明显下降的。

目的 为探讨糖尿病对脑血管的，而对脑动脉血流动力学进行对比。经临床诊断糖尿病50例，行TCDFI检测大脑中动脉、大脑前动脉、大脑后动脉等血管的血流速度指标及搏动指数、阻力指数，收缩期血流速度/舒张末期血流速度及频谱形态分析与健康组对照比对分析。结果(1)TCDFI频谱中，血流速度的变化，Vmax是非特异性的，而VE是明显下降的。

Our experiment showed that addition of benzydamine induced vasorelaxation in the denuded aorta precontracted with KCl in the normal krebs.

实验结果亦显示，benzydamine能抑制高钾所引起的收缩作用，并且藉由在无钙之Krebs溶液中，经benzydamine前处理的血管给予高钾刺激之后，再给予钙离子刺激血管收缩，发现其能抑制外钙内流所造成的血管收缩作用。

Effects of H_2O_2 on the tension of isolated aortic rings of rat As above methods,Our results indicated that (1) aortic rings with endothelium precontracted by NE to 10000μmol/L H_2O_2 induced a relaxation; aortic rings with endothelium to 100μmol/L H_2O_2 induced a significant contraction;H_2O_2 induced the same effects in aortic rings without endothelium, there is significant difference in presence and absence of endothelium.

双氧水对大鼠离体血管环张力的影响方法同2，结果：①NE预收缩后，加入10000μmol／L H_2O_2，内皮完整血管环表现为舒张作用；加入100μmol／L H_2O_2后血管环表现为收缩作用；H_2O_2对去内皮的血管环同样具有上述作用，与内皮完整组相比差异显著；②10000μmol／L H_2O_2可使得内皮完整及去内皮血管环中NO含量升高；100μmol／L H_2O_2可使得NO含量降低。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
