Thickened interlobular septa'looking as the "crazy-paving"'was found in 4 cases in high-resolution CT'correspondence with edema and lymphocyte exudation in interlobular septa in pathological findings.No mediastinal and hilar adenopathy was found. Conclusion The characteristic appearances of PAP on MSCT correspond to its pathological features.

多层CT的问世，使单次屏气时间内完成高质量的全肺薄层扫描成为现实，极大提高了图像的时间和空间分辨率，胸部高分辨率CT还能清晰显示次级肺小叶为单位的肺内细微结构，极大提高了CT在肺部疾病诊断中的应用价值。

There was no significant difference in epithelial destruction, intra-luminal obstruction and BO formation between allografts from HO-1 transgenic pigs or non-transgenic pigs. However, in day 28 and 56 allografts, we did see some of the grafts still showed bronchiole structure with normal epithelial cells which hasn'tbeen found before.

使用HO-1 基因猪的异体移植肺块，在气管表皮破坏、气管内径阻塞、及阻塞性细支气管炎形成的程度，与使用非基因猪并无显著差异，惟在第28 天及56 天的肺块中，有部份的异体移植肺块中可见正常的支气管型态及表皮细胞。

Objective To explore the changes of apoptosis of cells in the lung tissue of rats with silica instillation and to its significance in silicosis, and to clarify the role of caspase-3 in the apoptosis progress.

肺纤维化是一组由多种病因所引起的肺破坏性疾病，目前的治疗一直未能改善其不良的预后，故加深对肺纤维化的认识，并在此基础上发展新的治疗策略已尤为迫切[1]。

Three hours OLV does not cause injury of the nondependent lung, yet six hours OLV leads to injury of the nondependent lung. Low-dose ALM would not deteriorate the injury of the nondependent lung.

OLV 3hr不会造成无通气肺组织的损伤，而OLV 6hr则引起无通气肺组织的损伤：小剂量ALM在提高HPV反应，改善OLV期间动脉氧合的同时，并不加重无通气肺组织的损伤。

The loss of normal lung parenchyma leads to pulmonary hypertension that leads to thickening of the small arteries along with reduplication to form a plexiform lesion, as seen here in a peripheral pulmonary artery.

正常肺实质的损伤可导致肺血管的压力增高，在此切片肺动脉的周边部可见肺内小动脉的管壁增厚，管腔狭窄引起肺动脉血压增高。

objective according to 14 cases of patients with post-traumatic bronchial rupture of the ct and x-ray findings.analysis of its causes,trauma type,and ct,x-ray value and the advantages and disadvantages.methods 14 cases of bronchial rupture in patients with clinical data,x-ray,ct-chip analysis and summing up.results traumatic bronchial rupture study the performance of the main image①bronchial cut-off levy;②atelectasis and pulmonary fall levy③pleural effusion,pneumatosis;④mediastinum,subcutaneous emphysema;⑤many thoracic fractures;⑥traumatic wet lung,and so on.conclusion for traumatic bronchial rupture combined with x-ray and ct examination can be clearly diagnosed early.

目的 根据14例患者外伤后支气管断裂的ct和x线表现，分析其起因、外伤类型和ct、x线应用价值及优劣势。方法对14例支气管断裂患者的临床资料、x线平片、ct片进行分析、总结。结果外伤性支气管断裂的主要影像学表现①支气管截断征；②肺不张与肺坠落征；③胸腔积液、积气；④纵隔、皮下气肿；⑤胸廓多发骨折；⑥合并创伤性湿肺等。结论对于外伤性支气管断裂结合x线摄片和ct检查是可以早期明确诊断的。

By using β-NADPH-diaphorase histochemical staining technique,wefound for the first time that NOS activity was detected in the epithelium of airpathway and endothelium of vessels but was not detected in the small vessels(ID＜100μm),and the NOS express in pulmonary vascular endothelium of preascitic andascitic broilers were elevated,especially in the endothelium and smooth muscle layer ofsmall vesseles with thicker walls and of muscularized nomuscular artery in asciticbroilers.

本研究从田间自然发生腹水症的肉鸡群中选取正常肉鸡、亚临床腹水鸡和腹水鸡为实验对象，通过比较这三种肉鸡血流动力学、心电图、动静脉血血气、肺外动脉舒张反应性、肺血管结构以及肺组织一氧化氮合酶的活性和分布等方面的不同，探讨了肺动脉舒张能力在肉鸡肺动脉高压形成中的作用和机制。

We observed the correlation between the dynamic change of the serumconcentration of NOS and hemodynamics index,found the serum concentration ofNOS was depressed observably after lung contused and NOS was actived and arrivedpeak at 24h after injected LPS.L-arigin can improve hemodynamics index andthe lung wet/dry index in lung contusion phase; Aminoguanidine can improvehemodyamics index and the lung wet/dry index obviously in ARDSphase.

通过观察ARDS动物模型血清一氧化氮合酶浓度的动态变化以及与血气指标和血液动力学监测指标的关系，发现肺挫伤早期NOS的浓度明显降低，ARDS发生后NOS的浓度明显升高，并在24h达到其峰值，肺挫伤早期给予NOS促进剂、ARDS发生过程中给予NOS阻滞剂可明显改善血气及血液动力学指标、肺湿/干比。

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。

The diagnostic accuracy can be improved using the CT guiding spring core biopsy needle for percutaneous pulmonary biopsy for both malignant tumor and benign lesion. Especially for benign lesion the diagnostic accuracy with spring core biopsy needle was distinctive higher than that with fine needle aspiration.

CT导引下使用弹簧芯状活检针经皮肺穿刺活检的并发症发生率与细针针吸活检相近，对肺内良性病变和恶性肿瘤的诊断准确性同样具有较高的准确性，特别是对肺内良性病变的诊断准确率明显高于针吸活检。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
