Compared with the control, the lungs of 3-day-hyperxia-exposure group developed into edema, hemorrhage and inflammatory infiltration and this condition aggravated at the 7th day. The pulmonary septum was significantly widened at the 14th day, the interstitial fibrocytes as well as alveolar epithelial cells proliferated obviously, and the tendency of lung fibrosis was also presented. The results mentioned above showed that the modle of hyperoxia lung injury was successfully established, and the acute inflamationm was its early symptom while the fibrosis was its late manifistation. There was no positive cytes of IFN-γ in the lung of nomal rats, The positive cytes of the groups under hyperxia-exposure for 3, 7, 14 day, which climbed to the climax at the 7th day and began to decline from the 14th day, were found in alveolus epithlia,pulmonary interstitial, bronchoepithlia and macrophage.

高氧14天（5.46±0.30）虽有所下降，但同空气组比，差异仍然具有显著性（P.05）；BALF中蛋白含量高氧3天（0.45±0.10）、7天（0.66±0.08）、14天（0.79±0.14）显著高于空气组（0.18±0.08，P值均。05）；肺通透系数高氧3天（6.61±2.05）、7天（10.88±1.54）、14天（12.75±2.20）均明显高于空气组（2.99±1.27，P值均。05）；同时病理组织学改变也表明与空气组比较，高氧3天时肺组织水肿、出血、炎性细胞浸润，7天时进一步加重，14天时肺间隔明显增宽，间质纤维细胞和肺泡上皮细胞明显增生，出现肺纤维化倾向；以上结果均表明我们成功地建立了高氧肺损伤动物模型，且急性炎症反应是其早期表现，纤维化改变是其晚期表现。

Epithelial cells showing hybridization signal in cytoplasms predominated in the positive cells.

杂交阳性细胞中，胞浆出现阳性杂交信号的细胞占主要部份。

Desmosomal junctions were seen between cells. Conclusion The culture conditions used in the experiment are suitable for the primary culture of human laryngeal epithelial cells. The cultured cells will facilitate further research on etiology and pathogenesis of larynx carcinoma because of their proliferative and differentiative potency.

本实验采用的培养条件适宜人喉上皮细胞的生长，所获细胞纯度高，培养过程简便；从生物学行为来看，体外培养的人喉上皮细胞同样具有增殖能力和分化潜能，是进行癌变研究的良好对象。

The expression of p16INK4a protein was tested by immunochemical assay, and the life span in vitro of nasopharyngeal epithelial cells was calculated as population doublings.

我们应用老化相关半乳糖苷酶染色检测SA-β-Gal活性的表达情况，并利用免疫组化测定p16INK4a蛋白的表达。

Dissolution and detachment of these cells create epithelial erosions that characterize the disease.

Helicobacter pylori infection causes the defect of mismatch repair in eucaryotes, and microsatellite instability in gastric epithelial cells, which increases the spontaneous mutation of relative genes, and finally results in the susceptibility to tumors in human bodies.

H pylori 感染导致了真核细胞错配修复(mismatch repair， MMR)系统的缺陷，在胃上皮细胞中引起微卫星不稳定(micrsatellite instable， MSI)，使相关基因自发突变率增加，最终可导致机体对肿瘤的易感。
