Combined Effects of Fluoride and Aluminum on Liver Function of Mice / 环境与健康杂志

ABSTRACT

Objective To study the combined toxic effects of fluoride and aluminum on the liver of mouse and the probable mechanism. Methods Kunming mice were randomly divided into nine groups and treated with fluoride and aluminum through drinking watercontrol(tap water)group, 50 mg/L fluoride group, 150 mg/L fluoride group, 200 mg/L aluminum group, 600 mg/L aluminum group, 50 mg/L fluoride+200 mg/L aluminum group, 50 mg/L fluoride+600 mg/L aluminum group, 150 mg/L fluoride+200 mg/L aluminum group, 150 mg/L fluoride+600 mg/L aluminum group. After 24 weeks of treatment, the activity of ALT, AST, the content of TBIL, DBIL, IBIL, ALB, Ca, P and Mg in the serum was determined. Results Different doses of single fluoride or fluoride+aluminum led to significant different changes in the liver function(single fluorideF=2.61, P0.05). Compared with the control group, the Ca level in the serum decreased in the exposed groups except 150 mg/L fluoride+600 mg/L aluminum group(P0.05). Conclusion The combination of fluoride and aluminum at certain levels has a toxic effect on the liver, but the combination of fluoride and aluminum at high doses shows an antagonistic effect.
