【Abstract】 Objective To study the effects of fluorosis on oral mucosal cell and hepatocyte DNA damage in rats.Methods Two groups of male SD rats were provided with deionized drinking water containing 0( control group) and fluoride(150mg/L sodium fluoride) respectively for 4 weeks. Single cell gel - electrophoresis assay was used to test the DNA damage rate in rat oral mucosal cells and hepa-tocytes.Results The DNA damage rates of fluorosis group were 50.20% in oral mucosal cells and 44.80% in liver cells and were higher than that of the control group significantly. Conclusions The data indicated that fluorosis could induce oral mucosal cell and hepatocyte DNA damage in rats.更多还原
