Objective To study the protective effect and mechanism of endothelin-1(ET-1)-re- ceptor antagonist PD142893 on early ischemia-reperfusion injury in rats lung allografts.

肺缺血再灌注损伤是肺移植术后早期死亡的主要原因，寻找有效方法预防和减轻肺IRI，有着重要的临床意义〔'一3〕。

In this group,16 cases were involved in central pulmonary arteries (66.7%) and 4 cases with dilated bronchial arteries (17%),9 cases with pulmonary infraction (37.5%) whose pulmonary embolismic index was ranged from 24% to 83%, other 15 cases with no pulmonary infraction whose embolismic index was ranged from 5% to 61%,and there were significant difference between the two groups.

中央肺动脉受累16例，占66.7％（16/24），支气管动脉扩张4例，占16.7％（4/24），发生肺梗死9例，占37.5％（9/24）。9例发生肺梗死的肺动脉栓塞指数24％～83％（平均46.5％），15例非肺梗死的肺动脉栓塞指数5％～61％（平均21％），两组栓塞指数具有显著差异性。

The arterial blood gases, lung compliance, extravascular lung water content,morphology and the activity of superoxide dismutase were determined in 20 min following the treatment.

观察2小时期间的血气、肺顺应性，并进行血管外肺水量、肺组织SOD活性测定及组织形态学的观察。

The hepatopulmonary syndrome occurs when intrapulmonary dilatation causes hypoxemia in cirrhosis. The free radicals may play a significant contributory role in the progression of HPS, and flavonoid agents could protect against deleterious effects of free radicals.

这个太专业了，不当之处请见谅：肺内扩张导致肝硬化部位血氧供应不足时就会发生肝肺综合症，自由基在肝肺综合症进程中可能扮演了一个极其显著的角色，类黄酮剂能够防止自由基的毒害作用。。

Although the pathogenesis is not very clear, new understandings about development of pulmonary fibrosis has appeared in company with impenetration of cell biology research and molecular biology research. In a word, research of pulmonary fibrosis gradually appears to be integrated and multidisciplinary crossover.

尽管肺纤维化发病机制目前尚不完全清楚，但随着细胞生物学和分子生物学研究不断深入，对肺纤维化的发生、发展机制有了许多新得认识，肺纤维化机制的研究正逐渐走向整体化和多学科交叉方向。

The spiral CT scan can not only find out the pulmonary contusion cases opportunely, but also can estimate the injury position, character, degree, complication and prognosis, which as a diagnosed evidence for treated the patients timely and rightly. The CT scan will be implemented after injured 48H as a routinely practice. The delayed pulmonary contusion can not be assimilated completely, and may remained pulmonary fibrosis, pleural incrassation or conglutination.

CT不仅能及时发现迟发性肺挫伤，还可对发生的部位、性质、损伤程度、并发症以及预后等做出及时判定，为临床及时准确治疗提供可靠的诊断依据；应将伤后48h CT复查列为常规；迟发性肺挫伤不易完全吸收，易遗留肺纤维化及胸膜增厚、粘连。

On experimental day （ day 0 ）, the rats were intratracheally instilled with bleomycin （ 5mg.kg -1 .body weight ）,and then treated with Angelica Sinensis 100mg.kg -1 and 200mg.kg -1 until they were killed.

按 BLM 5mg.kg -1 体重复制大鼠肺纤维化模型， 24 小时后给药，于 7 、 14 、 28 天观察肺间质纤维化形成的病理变化和肺匀浆中谷胱甘肽、透明质酸的含量变化。

Except for control group, rats in the other groups were intratracheally administered with bleomycin. Animals in pulmonary fibrosis model groups were sacrificed on day 3, 7, 14, 28 and 56. The sections of the right lung were stained by HE, Masson and sirius red. The left lung was weighed and its hydroxyproline content was assayed. The mRNAs of TGF-β1, MMP-9 and TIMP-1 in the lung homogenate were measured by semi-quantitative RT-PCR.

除N组外，其余各组采用气管内注入BLM致大鼠肺纤维化模型，分别于3、7、14、28、56d处死各组大鼠，右肺行苏木精－依红、Masson胶原及天狼猩红染色，测定左肺经脯氨酸的含量RT-PCR法半定量测定转化生长因子－1(TGF-β1)、基质金属蛋白酶－9(MMP-9)和基质金属蛋白酶组织抑制物－1(nMP-1)mRNA在肺内的表达。

The morphologic changes of these three tissues were observed with light microscope and transmission electronic microscope; the pulmonary wet-to-dry weight ratio, the pulmonary weight indexs, and the ratio of the area of the multilamellar body to the area of cytoplasm in type II alveolar cell were measured. Results 1.The permeability of the pulmonary endothelial cells increased 2 hours after the injection of oleic acid.

经光镜和透射电镜观察对照组和实验组三种组织的形态学改变；并测定肺组织的湿干重比和肺系数；采用立体计量法测定肺II型细胞板层小体与细胞质面密度比。

Coagulation dysfunction does exist in neonates with pneumorrhagia caused by scleredema and asphyxia. Plasma TXB2 and FPA should be considered as the early objective monitoring indices in neonates who are highly suspected as having pneumorrhagia .

新生儿肺出血患儿存在血小板活化和异常凝血；窒息和硬肿症所致的新生儿肺出血都存在止血凝血功能障碍这一共同因素；TXB2和FPA可作为预测新生儿肺出血的早期客观监测指标。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
