摘要: 设计了一种新型的测试挥发性物质密闭容器装置,建立了一套简便、快速、实用的挥发性物质体外致突变定量检测方法。应用平衡原理测得挥发性物质培养基/ 气分配系数和致突变测试容器装置中空气浓度,通过简单公式计算,即可获得培养基中受试物浓度。整个定量分析过程仅需4h。挥发性物质在致突变测试容器装置内可保持特定的浓度,剂量与效应关系明确。在Ames 致突变测试中,对沸点低于100 ℃挥发性物质,必须用容器装置才能检测致变性,沸点在100 ℃以上,200 ℃以下,容器装置方法仍是首选有效的检测方法。

Abstract: A new sealed container for testing the mutagenicity of the volatile shbstance is designed and simple , repid and useful mutagenic quantitative method for these substances in vit ro is developed. The media/ air partition cofficient s and the concent ration in the container of the volatile ubstance are measured using the equilibration Princile. Then the concent ration of the substance tested in the media is got by simple formule. The whole procedure is completed during 4 hrs only. The given comcent ration of the volatile substance in the container can be kept , and the dose2effect relationship is clear. In Ames/ Salmenlla assay the result s suggested that , when volatile chemicals with the boiling Point of below 100 ℃are tested the mutagenic test must use the container ; when the chemicals with the boiling point of 100 ℃- 200 ℃are tested the container is still useful and elected firstly.
