Combined effect of cytostatic drugs and E-N-L-trimethyl lysine in healthy and transplantable tumor bearing mice.

E-N-L-trimethyl lysine (TML) decreases the toxicity of Vincristin, Cyclophosphamide and Doxorubicin (Adriamycin) when administered simultaneously to healthy mice. Simultaneous treatment of L1210 ascites leukemia bearing mice with 100 mg/kg TML and 2, 2.5, 3.2, 3.5, 4 mg/kg Vincristin or 10-15; 20 mg/kg Doxorubicin increases significantly the survival of the animals when compared with untreated and Vincristin or Doxorubicin treated mice. Repeated impulse treatment of S-180 subcutaneous sarcoma with 100 mg/kg TML and 50-100 mg/kg Cyclophosphamide results in a significantly higher surviving time and surviving rate than Cyclophosphamide treatment alone.
