在研究石棉粉尘对人体健康的危害程度和严重性方面,我们除了应用横断面调查和回顾队列调查等方法外,还作了一点新的尝试。其一,增加了典型病案的收集和分析,争取了活检和尸解;其二,配合了相应的动物实验;其三,还应用了彩色电视录象方法。 通过对某县青石棉污染情况的调查,我们体会到只搞一般的流行病学调查尚有不足,因此在多次现场考察的基础上,注意了间皮瘤病例的收集和分析。间皮瘤在我国是一种较为罕见的恶性肿瘤,与石棉关系密切,具有特异性。该县近几年来已发现
In addition to applying cross-sectional surveys and reviewing cohort surveys, we also made some new attempts to study the degree and severity of asbestos dust on human health. First, an increase of the collection and analysis of typical cases, for biopsy and autopsy; Second, with the corresponding animal experiments; Third, the application of color video recording method. Through the investigation of the pollution of crocidolite in a county, we realize that only conducting general epidemiological investigations still has some shortcomings. Therefore, on the basis of many on-site investigations, we pay attention to the collection and analysis of mesothelioma cases. Mesothelioma in our country is a relatively rare malignancy, and asbestos are closely related, with specificity. The county has been discovered in recent years
