目的 中药木回春体外抗肝癌作用研究。方法 采用~3H—TdR掺入法检测木回春对QGY—7703人肝癌细胞DNA合成的影响。结果 实验组QGY—7703细胞DNA合成量较对照组皆有明显减少,差异显著(P<0.001)。且DNA合成量随药物浓度增加呈减少趋势,ED_(50)浓度为270.968μg/ml。结论 木回春可能成为治疗肝癌的理想药物。 Objective To study the anti-hepatoma effect of Chinese herbal rejuvenation in vitro. Methods The effect of wood rejuvenation on the DNA synthesis of QGY-7703 human hepatoma cells was detected by ~3H-TdR incorporation method. Results Compared with the control group, the amount of DNA synthesis in the experimental group QGY-7703 cells was significantly reduced (P<0.001). The amount of DNA synthesis decreased with increasing drug concentration, and the ED_(50) concentration was 270.968 μg/ml. Conclusion The wood rejuvenation may be an ideal drug for the treatment of liver cancer.
