| 目的探讨咖啡酸锗对H22肝癌小鼠的体内抗肿瘤作用及其诱导细胞凋亡的机制.方法采用H22肝癌小鼠模型观察咖啡酸锗的体内抗肿瘤作用,透射电镜观察肿瘤细胞超微结构改变,免疫组化方法检测肿瘤组织中bax、bcl-2蛋白表达.结果咖啡酸锗对小鼠H22移植瘤的生长具有明显抑制作用,高、中浓度组抑瘤率分别为57.0%、40.4%(P＜0.01),电镜下可见典型的细胞凋亡形态特征.咖啡酸锗处理后肿瘤组织中bax蛋白表达明显增强,bcl-2表达降低(P＜0.05).结论咖啡酸锗对H22肝癌小鼠具有明显的体内抗肿瘤作用,同时 |

| Objective: To approach the effect of caffeic acid germanium to H22 hepatoma mouse and the mechanism of inducing cell apoptosis.Methods: Observe the effect of caffeic acid germanium to H22 hepatoma mouse in vivo,observe the ultramicro-structural change of tumor cell with transmission electron microscope,detect to the expression of bax,bcl-2 protein in tumor tissue with immunohistochemistry method.Results: There has the manifest depressant effect of caffeic acid germanium to the growth of mouse H22 hepatoma,the rate of restraining tumor of high and middle density group is 57.0%,40.4%(P<0.01).It is thus evident that morphologic characteristics of typical apoptosis in electron microscope.The expression of bax protein is increased and the expression of bcl-2 is decreased in the tumor tissue has been deal with caffeic acid germanium(P<0.05).Conclusion: There is evident effect of caffeic acid germanium to H22 hepatoma mouse in vivo,at the same time,it can prompt the expression of bax protein in tumor tissue and restrain the expression of bcl-2 protein,inducing the apoptosis of tumor cell. |
