动脉外膜

AIM:To study the effect of adventitia removal on vascular structure and function in spontaneously hypertensive rats.

目的： 研究自发性高血压大鼠去除一侧颈动脉外膜后血管结构和功能的变化。

The infiltration of inflammatory cells in adventitia and the hemodynamic oppression by myocardial contraction are related to the occurrence and development of these lesions.

动脉外膜炎症和心肌收缩对血管的挤压与病灶的发生和发展有密切关系。

Aim To investigate the effect of atorvastatin on intimal hyperplasia of carotid artery after adventitia removal in spontaneously hypertensive rats.

目的 研究阿托伐他汀对自发性高血压大鼠颈动脉外膜去除后血管内膜增生的影响。

A false aneurysm is the term applied when only the adventitia is present.

假性动脉瘤一词用于只有一层动脉外膜的动脉瘤。

Most of the neural input into blood vessels also traverses through the adventitia.

大部份输入血管中的神经中枢也会穿过动脉外膜。

The adventitia is the outermost layer of the artery and typically consists of a loose matrix of elastin, smooth muscle cells, fibroblasts, and collagen.

动脉外膜是动脉的最外层，典型上，包含了疏松的弹力蛋白基质、平滑肌细胞、纤维母细胞、以及胶原。

The proliferation of medial smooth muscle cells and collagenous fibers of pulmonary arteriole in patients with PH were observed by electron microscopy.

电镜下，中重度PH组肺细小动脉中膜平滑肌增生，外膜胶原纤维密集；轻度PH组肺细小动脉中膜平滑肌细胞和外膜胶原纤维增生轻于中重度PH组；无PH组肺细小动脉结构改变不明显。

The gland wall is a continuation of the carotid wall and consists of intima, media and extima.

组织结构显示：颈动脉腺的外壁是动脉管壁的延续，包括外膜、中膜和内膜。

People often occur in elderly vascular sclerosis, high blood pressure sustained more easily lead to cerebral arteriosclerosis, vessel wall hyalinization appears fat, thus weakening the strength of the vessel wall, together with the blood of the structure of the wall is relatively weak, the middle vascular myocytes less, the lack of external elastic layer developed arterial adventitia easily occurred in the brain artery wall limitations small expansion, the formation of micro-miliary aneurysm.

人到老年血管常会发生硬化，持续的高血压更容易导致脑动脉硬化，血管壁出现脂肪玻璃样变，从而削弱血管壁的强度，加上脑血管壁的结构比较薄弱，血管中层肌细胞少，缺乏外弹力层，动脉外膜不发达，容易造成脑内小动脉壁发生局限性扩张，形成粟粒性微动脉瘤。

Was simultaneously injected into cisterna magna at the second injection blood in the presence of subarachnoid blood. At 2 to 4 days, GFP was expressed in leptomeninges over the brain stem, cortex and cerebral arteries, smooth muscle cells of small vessels were occasionlly transduced. GFP was expressed in adventitia of spastic basilar artery on days 2 (day 5 after first injection blood) after injection 〓, but was undetectable by days 4, transgene was not expressed in medial or intimal layers. The prensence of subarachnoid blood can not prevent access of adenovirus to vessels and transgene expression.

注入腺病毒载体后2天（初次注血第5天）行荧光显微镜、免疫组织化学和RT-PCR检测，结果在颅内大血管如基底动脉的外膜可见外源基因的表达，而外源基因不能转移至血管中膜和内膜，4天时（初次注血第7天）基底动脉的外膜中外源基因表达消失；注入腺病毒载体后2～4天，外源基因可以有效转移至颅底软脑膜细胞，小血管外膜和平滑肌层也可见外源基因的表达，表明蛛网膜下腔内的血凝块不能阻止腺病毒载体介导外源基因转移至颅内血管。
