外膜层

免疫酶组织化学研究结果表明，NKB免疫反应神经纤维广泛分布于豚鼠下呼吸道各部：1.气管和支气管的上皮、平滑肌和外膜层；

NKB-immunoreactive fibers were demonstrated by immunohistochemistry in the following locations of the lower respiratory tract : 1 . within and beneath the lining epithelium , smooth muscle layer and tunica adventitia of the trachea and bronchus ;

结果缺氧后通过免疫组织化学可见15-LO蛋白质的表达增加，主要表达于心脏血管壁的外膜层，呈褐色颗粒，并且表达程度与缺氧时间呈正相关。

Results Protein expression of 15-LO gradually enhanced in tunica adventitia of blood vessel in the heart by immunohistochemistry . 15-LO were stained brown in tunica adventitia , and the expression of 15-LO increased as hypoxic time become longer in vivo .

外膜层较薄，主要为纤维组织，无外弹力层。

Tunica externa layer were thin , mainly fibrous tissue , no external elastic layer .

14天时表达减弱，阳性表达主要位于外膜层。

At POD 14 , the expression of ICAM-1 weakened , locating in the adventitia .

转移淋巴结对近侧支气管壁外膜层的间接浸润以腺癌最为突出。

The indirect invasion of metastatic lymph nodes in adenocarcinoma was more likely at the adventitial layer of proximal bronchial wall .

如果穿透肌层和外膜层，即发生溃疡穿孔，导致急腹症。

If the ulcer penetrates through the muscularis and through adventitia , then the ulcer is said to " perforate " and leads to an acute abdomen .

结果显示：①肺静脉壁的结构分为三层，即内膜层，中间层，外膜层。

The result of the second section suggested that : ? The pulmonary vein walls of dogs were composed of 3 layers : the tunica intima , tunica media and tunica adventitia .

IMA和RA内、中、外膜三层结构清晰，两者的显微结构很为相似。

The ultrastructure of intima , meddle layer and external membrane of IMA and RA are clear and similar .

输精管管壁由粘膜、肌层和外膜三层组成；

The tubal wall of spermatic duct is composed of mucosa , muscular layer and adventitia .

结果：人窦房结中央动脉管壁的纤维网架分为内膜、中膜和外膜3层；

Results : The collagen fibers of the central artery penetrated to the node may be divided into 3 layers : intima , media and adventitia .

结果表明：丽江山慈姑地上部分基本不含秋水仙碱，鳞茎秋水仙碱含量由外及内依次降低，其中外膜质层为0.134%和鳞茎外层为0.171%；

Contain few colchicine . The colchicine gradually reduce from outside to inner in the bulb of Iphigenia indica Kunth et Benth . , the outer-epidermis contain 0.134 % , the outer of bulb contain 0.171 % .

总体来看，强阳性细胞多分布于粘膜层和外膜，粘膜层游离端有强阳性物质分布，粘膜下层多呈弱阳性反应。

As a whole , strong positive cells were mostly observed in the tunica mucosa and adventitia , and positive material was observed on the dissociative side of tunica mucosa . Tunica submucosa showed weak positive reaction .

结果发现，血管内超声在颈内外动脉显现出内膜、中层和外膜的三层结构，在颈总动脉表现为难分层次的单层结构。

The results revealed that IVUS could show the typical three layers of structure ( intima , media and adventitia ) in the internal and external carotid arteries and the three layers of the commom carotid artery were hardly differentiated .

采用共聚焦免疫荧光术研究生长中侧支血管外膜中波形蛋白和层粘蛋白（FN）的表达变化；

Expression of vimentin and fibronectin in the adventitia was detected using confocal immunoflurescence .
