Mice were treated with 25 and 50 mg/L NaAsO2 for 1 and 3 months: (a) Control; (b) 25 mg/L NaAsO2-treated mice for 1 month; (c) 50 mg/L NaAsO2-treated mice for 1 month; (d) 25 mg/L NaAsO2-treated mice for 3 months; and (e) 50 mg/L NaAsO2-treated mice for 3 months. (f) Analytical result of the liver injury score. Data were expressed as . compared with control mice.
