目的 探讨新型基因工程人肿瘤坏死因子(nrh T N F) 和足叶乙甙( V P- 16) 的协同抗肿瘤作用及nrh T N F 的毒副作用。方法 以复制成功的 Lewis 肺癌(3 L L) 小鼠为模型局部用药。结果 nrh T N F 或 V P- 16 瘤体内注射均能使肿瘤生长及肺转移受到一定的抑制,抑瘤率分别为3371 % 、3046 % ,肺转移瘤数与对照组比较 P < 005 ,肿瘤出现一定程度坏死。而联合用药则能显著抑制肿瘤生长及肺转移,抑瘤率为6577 % ,大于理论抑瘤率5391 % ,肺转移瘤数与对照组比较 P < 001 ,肿瘤出现广泛的出血坏死。同时观察到nrh T N F 对实验小鼠无明显毒副作用。结论 nrh T N F 和 V P- 16联合应用,具有协同抗肿瘤作用,对于肺癌治疗具有进一步临床应用探讨价值。目的 探讨新型基因工程人肿瘤坏死因子(nrh T N F) 和足叶乙甙( V P- 16) 的协同抗肿瘤作用及nrh T N F 的毒副作用。方法 以复制成功的 Lewis 肺癌(3 L L) 小鼠为模型局部用药。结果 nrh T N F 或 V P- 16 瘤体内注射均能使肿瘤生长及肺转移受到一定的抑制,抑瘤率分别为3371 % 、30
Objective To investigate the synergistic anti-tumor effects of novel gene-engineered human tumor necrosis factor (nrh T N F) and etoposide (V P-16) and the toxic side effects of nrh T N F. Methods A model of Lewis lung cancer (3 L L) mice successfully replicated was administered topically. Results Intratumoral injection of nrh T N F or V P-16 could inhibit tumor growth and lung metastasis. The tumor inhibition rates were 33.7%, 30.4%, respectively. Pulmonary metastases were compared with the control group. < 005, the tumor appeared necrotic to a certain extent. The combined use of drugs can significantly inhibit tumor growth and lung metastasis, the tumor inhibition rate was 65.77%, greater than the theoretical tumor inhibition rate of 53.91%, the number of lung metastases compared with the control group P <0. 01, the tumor appeared extensive. Bleeding and necrosis. At the same time, it was observed that nrh T N F has no obvious toxic side effects on experimental mice. Conclusion The combination of nrh T N F and V P-16 has a synergistic anti-tumor effect, and has further clinical application value for the treatment of lung cancer.
