目的：为了探讨中药８８９对体外培养的癌细胞的影响。方法：我们观察了该药对人白血病粒细胞（Ｋ５６２）、肝癌细胞（Ｈｅｐｅｒ）和绿猴肾细胞（Ｖｅｒｓｅｎｓ，为正常细胞）生长的影响。结果：浓度在２０．８３～４１．６７μｇ／ｍｌ、作用时间为２４～４８ｈ时，Ｋ５６２细胞死亡率和抑制率分别为８０．６７～６８．３３％和８６．２７～７０．１０％；Ｈｅｐｅｒ细胞抑制率为６０．９８～７５．９４％，与空白对照组相比，Ｐ＜０．０５和０．０１，而对Ｖｅｒｓｅｎｓ细胞生长无影响。结论：我们初步认为该药有较强的抑制癌细胞生长和繁殖的能力 Objective: To investigate the effect of Chinese medicine 889 on cancer cells cultured in vitro. METHODS: We observed the effect of the drug on the growth of human leukemic granulocytes (K562), hepatoma cells (Heper) and green monkey kidney cells (Versens, normal cells). Results: At the concentration of 20.83～41.67μg/ml and the action time of 24～48h, the mortality and inhibition rate of K562 cells were 80.67～68.33% and 86.27～70.10% respectively; The cell inhibition rate was 60.98-7.94%. Compared with the blank control group, P<0.05 and 0.01, but had no effect on Versens cell growth. Conclusion: We initially believe that this drug has a strong ability to inhibit the growth and reproduction of cancer cells.
