Oral treatment with alpha-difluoromethyl ornithine (2.75 g/kg rat/day) simultaneous with subscapular implantation in Buffalo rats of the 5213, 1-1 hepatoma, retarded significantly the tumor growth rate for 20 days. The regimen also decreased tumor ornithine decarboxylase activity (ODC); however, the tumors growing despite treatment, maintained their malignant characteristics and ODC activity when re-transplanted into normal animals.
在布法罗大鼠肩胛下植入5213、1-1肝癌的同时,口服α-二氟甲基鸟氨酸(2.75克/千克大鼠/天),可显著延缓肿瘤生长速度达20天。该方案还降低了肿瘤鸟氨酸脱羧酶活性(ODC);然而,尽管接受了治疗仍在生长的肿瘤,当重新移植到正常动物体内时,仍保持其恶性特征和ODC活性。
