Abstract
目的 研究保肝延年注射液的抗肝癌作用.方法选择小鼠肝癌H22癌模型、MTT法和集落形成法,观察保肝延年注射液对荷瘤鼠和人肝癌SMMC-7721细胞株的作用.结果腹腔注射保肝延年注射液80mg/kg、160mg/kg、320mg/kg,肿瘤受到明显抑制,抑制率分别为72.5%、90.1%和94.6%(P＜0.05,P＜0.01);小鼠生存时间显著延长;在体外保肝延年注射液对人肝癌细胞有明显的细胞毒作用,其IC50为2.04 μg/ml;同时保肝延年注射液可抑制人肝癌SMMC-7221克隆原细胞形成集落,其IC50为2.35μg/ml.结论保肝延年注射液在体内和体外均具有抗肝癌作用。
