mg/kg/day. All animals survived. Pathological examination of organs showed microscopic changes in the
liver of the mid and high dose male and female rats. These changes were characterized by enlargement of
hepatocytes. Kidney changes were observed in the mid and high dose females. These changes were
characterized by an increased basophilia of the cortical tubules predominantly in the distal convoluted tubules.
The no effect level (NOEL) appears to be 50 mg/kg/day.
