矿尘的体外效应国际讨论会于1979年9月4日至7日在英国威尔斯的尘肺研究所举行。有12个国家75名代表参加。会议审查了关于粉尘生物学体外效应研究的不同技术,提出了大量的各种粉尘试验材料,但以石棉尘为主。曾有报告用溶血作用强弱来分类矿尘,但会议上普遍认为溶血不能很好地预测粉尘在体内的致病性,但不失为研究矿尘与生物膜作用的有效方法。会议重点交流讨论了巨噬细胞及其他细胞的毒性试验。注意到不同种的巨噬细胞及身体不同部位的原始巨噬细胞可能有不同的反映,在会上报告过应用小 The International Symposium on In Vitro Effects of Mine Dust was held at the Institute of Pneumoconiosis in Wells, UK, from September 4 to 7, 1979. 75 delegates from 12 countries participated. The meeting reviewed different techniques for studying the in vitro effects of dust biology and proposed a large variety of dust test materials, but mainly asbestos dust. It has been reported that hemolysis is used to classify mineral dust. However, it is generally accepted at the conference that hemolysis can not predict the pathogenicity of dust in vivo, but it is an effective method to study the effect of mineral dust and biofilm. The conference focused on the exchange of toxicological tests of macrophages and other cells. Noting that different types of macrophages and primitive macrophages in different parts of the body may have different reflections, at the meeting reported the application of small
