查询词典 occlusion

H after last preconditioning, the spinal cord ischemia was induced for 20 min by infrarenal aortic occlusion.

最后一次预处理结束后24 h，夹闭所有动物腹主动脉肾下段20 min，制作兔脊髓缺血模型。

Arterial thromboses can extend proximally in aortic lesions causing infrarenal occlusion of the aorta.

动脉血栓可以延长近端的主动脉病变造成下腹主动脉闭塞。

Judging from the improved degrees of occlusion relationship,it seems that the improvement of anterior segment is better than that of posterior segment;the improvement of intraarch relationship is better than that of interarch: the improvement of buccal relationship is better than that of lingual.

合关系的改善程度，是前牙优于后牙；牙合内优于牙合间，颊侧优于舌侧。

ABSTRACT］ObjectiveTo investigate the efficacy and safety of combination of intravitreous injection of triamcinolone acetonide and laser therapy for macular edema due to retinal vein occlusion.

目的 了解玻璃体腔内注射曲安奈德联合视网膜激光光凝治疗视网膜静脉阻塞引起的黄斑水肿的有效性和安全性。

ConclusionCombo therapy of intravitreous injection of TA plus retinal photocoagulation can effectively treat macular edema caused by retinal vein occlusion and improve patients' vision, but recurrence or increase of intraocular pressure may occur in some of them.

结论玻璃体腔内注射TA联合视网膜激光光凝可以有效治疗RVO引起的黄斑水肿，提高视力，部分病人可出现高眼压、黄斑水肿复发等并发症。

Objective To investigate the change of ipsilateral substantial nigra after middle cerebral artery occlusion.

目的 研究大鼠大离中动脉闭塞后同侧黑质的变化。

Site of occlusion and involvement of the lenticulostriate arteries were confirmed by angiography.

动脉闭塞的位置及豆纹动脉究竟是否受累，则通过行脑血管造影来进一步明确。

Therefore, site of arterial occlusion and involvement of the lenticulostriate arteries may be presumed, to some extent, by precise evaluation of early CT signs in the deep MCA territories.

因此，从某种程度上说，通过对深部大脑中动脉分布区出现的早期CT征象进行精确的评估，可以推测出动脉闭塞的位置及豆纹动脉是否受累。

When the MCA trunk is occluded at its origin, and all of the lenticulostriate arteries are involved in ischemia (type 1 occlusion), hypodensity usually extends to the entire lentiform nucleus.

当大脑中动脉主干的起始段发生闭塞、造成所有豆纹动脉均受累缺血（1型大脑中动脉闭塞）时，通常整个豆状核区都会出现低密度

On the basis of these considerations, we investigated the incidence of parenchymal hypodensity within 3 hours after symptom onset and assessed the correlation of early CT signs in the deep MCA territories with involvement of the lenticulostriate arteries among patients with angiographically proved embolic MCA occlusion.

基于以上这些原因，本研究调查发病3小时以内、经脑血管造影证实大脑中动脉栓塞的患者，CT表现出梗塞区脑实质低密度的发生率；并评估深部大脑中动脉分布区早期CT征象与豆纹动脉受累之间的关系。

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。
