Abstract:
Hydralazine (1-hydrazinophthalazine) was administered in drinking water as a 0.0312% solution to randomly bred Swiss mice for life beginning at 5 weeks of age. The treatments gave rise to statistically significant incidences of lung tumors: 55% in females and 43% in males. A decreased copper concentration and superoxide dismutase activity in the lung of mice were observed. The role of copper and superoxide dismutase in the malignant process is briefly discussed.
