肺泡的

The respiratory portion begins when an air sac first arise which appears as an outpocketing of the bronchiole.

呼吸性细支气管：壁上有散在的肺泡开口，上皮为单层立方上皮，在肺泡开口处，移行为单层扁平上皮。

RESULTS: The expression of VCAM1 in the lung tissues of normal rats was weak, and distributed mainly in alveolar epithelial cells, bronchiole epithelial cells, alveolar macrophage and some pulmonary interstitium.

结果： 在正常对照组，VCAM1大鼠肺组织中呈弱表达，分布于肺泡上皮细胞、细支气管上皮细胞、肺泡巨噬细胞及少量的肺内间质。

After repeffusion alveolar capillaries were engorge, miM infiltration of the inflammatory cells and minimal interstitial edematous was seen in the perivascular.

仅12、18和24h组可见灶状肺泡萎陷；缺血-再灌注组的肺小动脉及血管内充血，部分肺泡壁血管充血伴周围炎性细胞渗出。

The method is characterized by induction equability, stabilization during operation, analepsia rapidly,accelerated progress of healing up, so it is the first effective way to treat pulmonary alveolar proteinosis.

静脉全麻下大容量全肺灌洗治疗肺泡蛋白沉积症具有诱导平稳、术中血流动力学稳定、术后苏醒迅速，疗效好等优点，为肺泡蛋白沉积症的首选治疗。

CT can well display the lesions of hepatic ang pulmonary alveolar hydatid cyst, and is of high value for the diagnosis.

螺旋CT可以很好显示肝肺泡状包虫病病灶，对肝肺泡状包虫病具有较高的诊断率。

The superficial microvascular networks were sparser, while the subpleural microvascular networks were denser. The superficial blood vessels and the interlobular blood vessels were mutual transitional, and the anastomosing between the superficial blood vessels with the subpleural vessels. According to the branching sequence of the subpleural arteriole, it could be divided into the arteriole, terminal arteriole, precapillary arteriole and capillary in turn. The subpleural capillary networks were mainly web-like, while small holes were also found on the cast. The honeycomb vascular networks were various in size and form at a low magnification. The outline of alveolus, alveolar sac, alveolar duct and respiratory bronchiole and terminal bronchiole, made of microvascular networks, could be found in the cut surface.

胸膜面浅层的微血管网稀疏，深层的胸膜下微血管网致密；胸膜面浅层的微血管与小叶间隔的微血管之间相互移行，与胸膜下微血管之间形成吻合连接；根据胸膜下微动脉连续分支的顺序，常可将其分为微动脉、终末微动脉、毛细血管前微动脉和毛细血管四级；胸膜下毛细血管网主要以网络状的形式存在，但在铸型上均可见数量不等的"小孔状"结构；低倍镜下肺实质内微血管网呈现大小不等、形态各异的蜂窝状结构，可以见到由微血管网构成了肺泡、肺泡囊、肺泡管和呼吸性细支气管以及终末细支气管等结构的轮廓。

The positive expression of TGFβ1, PDGF-B rnRNAs and their proteins were prominent in the proliferative alveolar type Ⅱ cells of experimental group of silicotic models. Weak expression of TGFβ1 mRNA were found only in a part of normal alveolar type Ⅱ cells of control group.

2大鼠矽肺实验组增生的肺泡Ⅱ型细胞明显表达TGFβ1和PDGF-B mRNA和蛋白；对照组仅有部分正常肺泡Ⅱ型细胞TGFβ1 mRNA呈弱阳性。

The relationship between the morphological features and the adaptability to lower-oxygen was analyzed by stereoscopy.

牦牛肺小叶结构明显，肺泡Ⅰ型上皮菲薄，构成肺泡壁的绝大部分。

The HE and the VG stain were pathologically examined and the expression of TGF-β1 and TNF-α mRNA in the lung tissues were analyzed by nucleic acid hybridization in situ. Results: YQHX1,2,3 obviously alleviated rats alveolitis and fibrosis.

结果：模型组肺泡炎和肺纤维化程度较重，且其胶原纤维沉积较多，TGF-β1、TNF-α的表达增多；而中药治疗组肺泡炎和纤维化程度较轻，胶原沉积明显减少，TGF-β1、TNF-α表达减少。

The experimental group has various changes in the different density of potentill anserine extract. the small rat pulmonary tissue surface ofⅰgroup can see sporadic petechia of different degree; pulmonary alveolus cavity can see sporadic erythrocyte under the microscope. the small rat pulmonary tissue surface of ⅱ group is no obvious abnormality by naked eye; pulmonary alveolus cavity can see sporadic erythrocyte and thin powder color liquid under the microscope.

实验组不同浓度的蕨麻提取物对小鼠肺组织的影响不同，ⅰ组小鼠肺组织表面肉眼见不同程度的散在点状出血、显微镜下肺泡腔内见散在红细胞；ⅱ组小鼠肺组织表面肉眼无明显异常，显微镜下肺泡腔内见散在红细胞及淡伊红色液体，两组均见肺泡壁毛细血管扩张充血及毛细血管内皮细胞呈不同程度的增生肥大。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
