本文采用非暴露式气管注入法对大鼠一次染尘50mg，染尘后15、45、90、180和270天分批剖检，测定支气管肺泡灌洗液中二棕榈酰卵磷脂含量，同时对肺组织标本进行扫描电镜观察。

Results Compared high kV X-ray chest film with spiral CT,to simplex silicosis,X-ray films coincided with CT scans;to mixed silicosis,the effect of CT scans were better than X-ray's;to large nodule,coalesced progressive massive fibrosis,the detected ratio of CT scans were higher than X-ray chest films;to silicosis complication,for example,emphysema,pleural thickening,phthisic,mediastinal impairment lympy node etc,CT scans were more reliable than X-ray films,especially HRCT can earlier find silicotic nodule and fine structure of focus.Selective application of CT scan,had great diagnostic value in complicated silicosis and silco-tuberculosis and lung cancer complicated with silicosis etc.

结果 高千伏X线胸片与螺旋CT作对比，结果对单纯矽肺并发肺癌，CT片与X线胸片基本一致；对于复杂矽肺并发肺癌CT优于X线胸片；对于大结节、肺内进行性大块纤维化(progressive massive fibrosis，PMF)融合、空洞及钙化CT检出率明显高出胸片；对矽肺并发肺癌的合并其他如肺气肿、胸膜肥厚、结核、纵隔淋巴受累等CT均较胸片可靠；特别是HRCT能早期发现矽肺肿块样病灶中细微结构，选择性应用CT，对复杂矽肺并发肺癌合并结核等鉴别诊断有很大价值。

AIM: To study the expression of MMP2 and MMP9 in fibroblasts of rat silicotic fibrosis model and its significance.

Spiral CT is superior to radiography in detecting the silicotic nodule and complications, and it has a practical value in the diagnosis of this condition.

螺旋CT在矽肺大小结节的显示及并发症的检出上优于X线平片，对矽肺的正确、综合诊断具有重要价值。

ConclusionSpiral CT is superior to radiography in detecting the silicotic nodule and complications, and it has a practical value in the diagnosis of this condition.

螺旋CT在矽肺大小结节的显示及并发症的检出上优于X线平片，对矽肺的正确、综合诊断具有重要价值。

The greater the degree of exposure to silica and increasing length of exposure determine the amount of silicotic nodule formation and the degree of restrictive lung disease.

暴露在硅石中的程度和暴露时间的长短决定了矽结节形成的数量和限制性肺疾病的程度。

The relationship of the changes in chest radiograph and silicotic pathology to the content of lung quartz, and the biochemical indices was studied.

结果说明肺石英量的多少直接影响了矽肺病变和肺部X线改变的程度。

Methods Cultivation of alveolar type Ⅱ cells were mode from normal adult rat and of silicotic animal model of rat was established. In situ hybridization and irnmunohistochemieal staining were applied to detect the gene expression of TGFβ1 and PDGF-B in the alveolar type Ⅱ cells of primary culture and silicotic tissue.

分离培养正常成年大鼠肺泡Ⅱ型细胞，建立大鼠矽肺模型，用原位杂交和免疫组化技术检测体外培养的和矽肺病变中的肺泡Ⅱ型细胞TGFβ1和PDGF-B mRNA和蛋白的表达。

The results showed that SiO2 and total protein contents, PAM numbers and LDH activity in silicotic rats decreased gradually with the severity of silicotic pathologic changes.

结果表明，矽肺大鼠BALF中SiO2粉尘和总蛋白量以及细胞总数和LDH活性，均随矽肺病变加重而逐渐减少。虽然，BAL对不同程度矽肺病变均能洗出一定量的细胞和非细胞成分的物质，但以早期病变组排出量最多。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
