为什么有些物质颗粒(粉尘)吸入肺后会引起胶原纤维化或其他病变而有些则否?这些问题目前尚未得到确切的了解,但有一点是肯定的:每一类尘肺所产生的病变首先决定于吸入尘粒的特性和机体对它的反应:肺部合并感染可能亦起一定的作用。这当中就涉及细胞学、免疫学和酶的活性等一系列问题,应用电子显微镜来观察病变所产生的细胞内变化,将会提供有关发病机理方面一些很宝贵的资料。各种类型尘肺的发病机理学说已有较详细阐述,这里仅介绍一些有关近代的看法。
Why do some substance particles (dust) inhale into the lung can cause collagen fibrosis or other diseases while others are not? These problems have not yet been clearly understood, but one thing is certain: the type of pneumoconiosis that occurs in each type of pneumoconiosis depends primarily on The characteristics of inhaled dust and the body’s response to it: Pulmonary infection may also play a role. This involves a series of questions such as cytology, immunology and enzyme activity. Using electron microscopy to observe the intracellular changes caused by the lesion will provide some valuable information on the pathogenesis. The theory of the pathogenesis of various types of pneumoconiosis has been elaborated in more detail. Only a few opinions on modernity are presented here.
