目前环境保护工作需要对大量化学物质的致癌性进行检查,若使用常规动物试验方法,需要大量人力物力,费时亦较长,一般需两年左右始得结果,这无疑远远落后于实际需要。近年,逐渐发展了一些快速、简易鉴定方法,微生物诱变试验(Ames法)属其中一种。对该法使用价值国外已有较肯定的结论,但国内使用尚少。本文拟根据有关文献 At present, the environmental protection work needs to examine the carcinogenicity of a large number of chemical substances. If the conventional animal test methods are used, a large amount of manpower and material resources are required, which takes a long time and usually takes about two years to start to produce results. This undoubtedly lags far behind actual needs. In recent years, some rapid and simple identification methods have been gradually developed, and the Ames test is one of them. The value of the law abroad has been more positive conclusion, but domestic use is still small. This article is based on the relevant literature
