| Abstract: | Objective To investigate DNA damages of liver cells and lymphocytes of rats exposed to vinyl chloride monomer(VCM), to examine the changes of hepatic function, and certain biochemical indexes. Methods DNA damages were detected by single cell gel electrophoresis (comet assay). The activities of metabolizing enzymes were measured by spectrophotography, and hepatic function was determined by biochemical analyser. Results The incidence rates of comet cells in the experimental groups were significantly higher than those of the controls; and the rates of comet cells between liver cells and lymphocytes among the groups were closely correlated. Conclusion VCM could induce DNA damage of liver cells and lymphocytes, where was a dose-effect/response relationship. |
