[Comparative study of antineoplastic and immunosuppressive properties of ftorafur].

In experiments staged on mice with transplantable leukemia L 1210 an immunodepressive and antineoplasic action of phthorafur was studied. Depending upon its dose phthorafur lowered the number of lymphoma colonies and antibody-forming cells in the spleen of the animals immunized with sheep erythrocytes. The maximal immunodepressive action was found to set in following administration of the agent in a dose of 500 mg/kg 24 and 48 hours after antigenic stimulation.
