The modification potentials of germanium on the development of preneoplastic hepatic enzyme altered foci were examined in an in vivo mid-term assay system. Two week after the initial single ip dose(200 mg/kg) of diethylnitrosamine (DEN), administration of germanium at a concentration of 0.05% on the diet was commenced simultaneously with an ip injection of D-galactosamine at a dose of 300 mg/kg body wt. All rats were subjected to two thirds partial hepatectomy at week 5 and sacrificed for assessment of lesion yield at week 8. The modifying potential was scored by comparing the number and area per §² of induced glutathione S-transferase placental form-positive (GST-P+) foci in the liver with those of the corresponding control-group given DEN alone. Germanium showed no statistically significant increase in the number, area and mean diameter of GST-P^(+) foci.
