title: [No increase in chemotherapeutic effectiveness of cyclophosphamide (CPA) in rat leukemia L 5222 by 5-ethyl-2'-deoxyuridine (EDU) (author's transl)].
abstract: Monotherapy of early rat leukemia L 5222 with 5 X 100 mg/kg EDU over 48 h yielded no increase in lifespan as compared to untreated controls. Combination therapy of advanced L 5222 with EDU and CPA in four different schedules results in no increase in life-span as compared to treatment with CPA only. DNA histogrms of preterminal L 5222 revealed no synchronizing effect of EDU.
