Ang-1is a sort of chemotactic factor for vascular endothelial cell and a kind of promoter for angiogenesis.

Ang-1对血管内皮细胞具有明显的趋化作用，是新生血管形成的促进因子。

They stimulate endothelial cell proliferation and the growth of new blood ve els by releasing endothelial mitoge and chemotactic factors, such as bFGF and vascular endothelial growth factor .

它们能刺激内皮细胞的增殖和血管的生长，通过释放内皮有丝分裂和化学趋化因子，例如bFGF和血管内皮生长因子。

Results In 70 cases of primary hepatoma,20 cases involved portal vein and inferior vena cava; in 34 cases of pancreatic carcinoma, 29 involved vessels; and cholecystic carcinoma and gastric carcinoma never involved vessels.

结果 70例原发性肝肿瘤中20例累及门静脉或下腔静脉，34例胰腺癌中29例累及血管，胃癌及胆囊癌均未累及血管。

OBJECTIVE: To observe the inhibitory effects of hAS/293 and hES/293 cells on angiogenesis in chick chorioallantoic membrane.

目的：观察以基因工程技术构建的人血管抑素/293细胞和人内皮抑素/293细胞对鸡胚尿囊膜血管新生的抑制效应。

The terpenoid and its crude extracts were used to treat on blood vessel of chick chorioallantoic membrane, as well as human umbilical vein endothelial cell.

通过鸡胚绒毛囊膜和人脐静脉内皮细胞研究了白芨中萜类化合物及其粗提物对血管及血管内皮细胞的抑制作用。

Finally, sophisticated in io models, such as rodent models of peritoneal endometriosis as well as the chorioallantoic membrane assay and the dorsal skinfold chamber,allow for the detailed analysis of blood essel deelopment in ectopic endometrium and the efficacy of angiogenesis inhibitors.

最后，复杂的体内模型，例如腹膜的子宫内膜异位，绒毛膜尿囊膜分析和背部皮肤皱褶腔的啮鼠动物模型，在异位子宫内膜和血管生成抑制剂效用中考虑了血管发展的详细分析。

The chief changes were the RPE and choriocapillaris atrophy in FFA and ICGA with the MPPE in quiescent phase, but the choroidal circulation anomalies disappeared including the choroidal filling delay and dilated.

静止期MPPE患者在FFA和ICGA中的荧光改变则主要为RPE和脉络膜毛细血管的萎缩，而脉络膜血管充盈迟缓和血管扩张等循环异常变化基本消失。

Refractive error and axial length are two main factors that offect the severity of maculopathy. Besides, the histopathogenesis of macular area showed obliteration of choriocapillary and aging factor was suggested to involve in those small vessel obstruction.

近视度数和眼轴长是影响黄斑部病变严重性最主要的两项因素，另外，由黄斑部的组织病理学可看出脤络膜血管的阻塞，而年龄因素被认为是造成小血管阻的主因。

Creating chorioretinal venous anastomosis potentially offers a means of permanently bypassing the site of obstruction to venous outflow, to recovery the retinal blood circulation and to reduce the retinal ischemia. It is one of the methods curing the reason of CRVO and is demonstrated effective in non-ischemic CRVO patients using laser-induced chorioretinal venous anastomosis. Patients with ischemic CRVO have more severe situations and high risk factors of later neovascular complications occuring, the surgery of via a pars plana vitrctomy combined chorioretinal venous anastomosis can be the newest attempting treatment.

其发病机理和病因目前仍未完全阐明，也没有有效的治疗措施；除常规的药物和针对新生血管并发症的视网膜光凝治疗以外，近年来开展的各种旨在重建或恢复视网膜血液循环的激光和手术治疗方法正日益成为眼科界关注的焦点；利用建立脉络膜视网膜静脉吻合途径，使被淤滞的静脉血流经由脉络膜血管流出眼外，促进或者恢复视网膜血液循环，减少视网膜缺血缺氧状态的发生，是多途径CRVO对因治疗的方法之一。

Objective To investigate the expression of pigment epitheliumderived factor and vascular endothelial growth factor in choroidal melanoma.

目的 观察脉络膜黑色素瘤中血管内皮生长因子和色素上皮衍生因子的表达，探讨两者在脉络膜黑色素瘤血管生成、肿瘤生长和浸润转移中的作用。

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。
