测定尘肺病人及实验动物肺中碳尘和二氧化硅含量,可以阐明粉尘对肺部损害的性质及严重的程度,是掌握粉尘致病作用剂量与效应间关系的基本材料,因此有必要寻找简单而又精确的肺内粉尘测定方法。在处理样品时,需消化肺组织,浓集粉尘,常用的消化方法有干式和湿式两种,如需同时测定肺中碳尘时,则需用湿式消化法,常用消化组织的试剂 Determination of carbon dust and silica in the lungs of patients with pneumoconiosis and experimental animals can clarify the nature and severity of dust damage to the lungs and is the basic material for understanding the relationship between the dose and effect of dust pathogenicity and therefore it is necessary to find a simple And accurate method of determination of lung dust. In dealing with the sample, the need to digest the lungs, dust concentration, commonly used digestion methods are dry and wet two, for the simultaneous determination of lung carbon dust, you need to use wet digestion, commonly used digestive tissue reagents
