There were no detectable differences in relative food consumption due to the addition of ascorbic acid or to an interaction of ascorbic acid with 2-AAF. However the presence of ascorbic acid in the water was associated with a significant reduction in relative water consumption. The addition of 2-AAF caused a significant increase in relative water consumption, and a significant interaction of ascorbic acid with 2-AAF was detected. Major histological findings were restricted to the urinary bladder. Vacuolization of the transitional epithelium, simple and nodular urothelial hyperplasia, fibrosis, and chronic inflammation of the lamina propria were found in varying degrees in the urinary bladders of mice receiving 2-AAF alone and in combination with ascorbic acid. The most severe lesions were seen in the mice given the combination of 2-AAF and ascorbic acid. The urinary bladders of mice receiving the control diet and ascorbic acid alone were normal. The chronic inflammation and fibrosis were restricted primarily to the fundus of the urinary bladder.
