This presentation reports on newer animal models and techniques that we and others have developed. These models attempt to predict in a reasonable experimental time frame the occurrence of structural changes in the lungs that are the basis of various chronic diseases. Since the major chronic diseases of the lung parenchyma involving what we think of as well-understood structural changes are pulmonary fibrosis and emphysema, I will discuss in detail ways of looking at effects of air pollutants on lung collagen and lung elastin metabolism.
本报告介绍了我们及其他研究人员所开发的更新型动物模型和技术。这些模型试图在合理的实验时间范围内预测肺部结构变化的发生情况,而这些结构变化是各种慢性疾病的基础。由于肺实质的主要慢性疾病涉及我们认为已充分了解的结构变化,即肺纤维化和肺气肿,因此我将详细讨论研究空气污染物对肺胶原蛋白和肺弹性蛋白代谢影响的方法。
