title: Anti-tumor activity of 1-acetyl-3-o-toluyl-5-fluorouracil against murine hepatoma MH134 and its effects on tissue weights following subcutaneous and oral administration.
abstract: Anti-tumor activity of 1-acetyl-3-o-toluyl-5-fluorouracil (A-OT) against MH134 solid tumors in mice was studied following subcutaneous and oral administration and compared with that of 5-fluorouracil (5-FU) administered subcutaneously at doses of 0.2, 0.4 and 0.6 mmol/kg/d. Oral administration of A-OT demonstrated a remarkable effect on MH134 solid tumors, the effect being more marked than that of subcutaneous administration of A-OT. Anti-tumor activity of oral administration of A-OT at a dose of 0.2 mmol/kg/d was comparable to that of subcutaneous administration of 5-FU at the same dose. The level of decrease in thymus weight and the magnitude of increase of spleen weight following oral administration of A-OT at any dose were smaller than those by subcutaneous administration of 5-FU (0.2 mmol/kg/d).
