Electron microscope: endocytoplasmic reticulums expanding and breaking, ribosomes defluxion, lysosomes increasing, vascular endothelial cells swelling and blood vessels congestion appeared in all groups, and the mitochondria swelling is serious in the groups which pressures were more than 400 kPa.

电镜下可见内质网扩张、断裂，核糖体脱落，溶酶体增多，血管内皮细胞肿胀、血管淤血等在各压力均可发生，线粒体肿胀变形以400KPa以上压力组为明显。

Results: radiation-induced depolymerization of F-actin microfilament stress fibres was dependent on the radiation dose.

电离辐射对血管内皮细胞骨架蛋白F-actin的破坏可能是血管内皮细胞辐射损伤机体机理之一。

Observed the effect of renal sympathetic nerve activity in depressor reflex induced by phenvlcphrine by intravenous injection, after anesthetized rats were injected vasopressln antagonist OPC-2 1 268 in lateral ventricle, inquire into centre regulatory function of vasopressin in baroie flex.This experiments was performed on male Wistar rats weighting 280?

然而，在中枢对压力感受性反射的调制作用却有不同的提法在实验观察麻醉大鼠侧脑室注射血管升压素受体1阻断剂OPC-21268对静脉注射苯肾上腺素诱发的减压反射中所表现的肾交感神经放电活动的影响，探讨血管升压素在压力感受性反射的中枢调节作用。

Endothelial Ang-2 expression is associated with essel destabilization and regulates a balance between ascular regression and growth.

血管内皮的Ang-2 的表达与脉管的不稳定性有关，其可调节血管的退化与生长之间的平衡。

Four episodes of massive bleeding occurred before a definite diagnosis could be established by angiography. A high index of suspicion is the most important diagnostic aid that can prevent the physicians from overlooking the possibility that lower GI hemorrhage may have such an unusual source.

病人在经历四次动脉血管摄影后出血才得到确切控制，唯有临床高度怀疑且快速准确的动脉血管摄影检查，才可避免轻忽此一罕见下消化道出血原因，并得到立即有效的治疗。

The variation of plasma vasoactive peptide concentration was not only related to UAP attack but also significant to the maintance coronary diastole and corculation.

UAP的发生与血管活性肽的变化密切相关，血管活性肽对维持冠脉舒张和循环有重要意义。

So there are two ways to attack the vascular smooth muscles in terms vascular dilatation.

因此，就血管舒张而言，有两种途径来攻击血管平滑肌。

Dilation of a blood vessel, as by the action of a nerve or drug.

血管扩张血管的扩张，如由于神经或药品

It suggested that the disbalance between proliferation and apoptosis which might be relative to abnormal expression of c-myc may contribute to pulmonary vascular structural remodeling.

提示增殖和凋亡现象共存在于正常和处理大鼠的肺血管细胞中，也许c-myc等基因的导常表达导致了细胞增殖和凋亡的失衡，进而调节了慢性低氧肺血管结构的改建。

In the current study it is difficult to be certain that the decreased aortic distensibility in aortic dissection were due to structural changes of the aortic wall, or simply reflected dilated aortic dimension and aortic valve regurgitation. Further study is necessary to elucidate the underlying mechanisms for this abnormalities.

本研究用无创的超声技术证明主动脉夹层之升主动脉扩张性明显降低，这对主动脉夹层病因学的进一步深入研究无疑具有重要意义；但其降低是由于血管本身结构异常所致还是继发于血管内径的扩张尚有待进一步深入研究。

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。
