ABSTRACT
Objective To detect the mutagenicity of sulfur mustard in the tk gene of L5178Y3.7.2c tk +/- mouse lymphoma cells. Methods The plating efficiency and the mutant frequency were detected by the microtiter procedure. Results Sulfur mustard induced tk locus mutation with mutation frequency 2-15 times higher than that of spontaneous mutation frequency of L5178Y3.7.2c tk +/- cells. There were two different phenotypes of mutation colonies induced, which were large and small colonies, but most of them were small colonies. Conclusion Sulfur mustard is characterized by marked mutagenic activity and cytotoxicity. The compound may result in large range of DNA damage.
