白术对小鼠移植性肉瘤S180的抑瘤作用及对Bcl-2基因表达的影响

目的 探讨白术对小鼠S180肉瘤的抑制作用及对肿瘤凋亡相关基因Bcl-2表达的影响.方法 昆明系小鼠60只,皮下注射S180细胞,同时分别给予白术、环磷酰胺处理小鼠,其后2周内测量各组肿瘤生长大小;采用RT-PCR法检测凋亡抑制基因Bcl-2的表达.结果 白术组的肿瘤重量低于模型组而大于环磷酰胺组(P均<0.05),但白术抑制肿瘤生长的作用强度未呈现量效关系,且其抑瘤率不及环磷酰胺(P<0.05);与对照组相比,白术能显著抑制肿瘤Bcl-2基因的表达水平(P<0.05).结论 白术具有抑制肿瘤生长的作用,可作为肿瘤治疗的辅助药物.

Baizhu suppresses S180 sarcoma growth and inhibits Bcl-2 expression in tumor-transfected mice

Objective To study Baizhu's inhibitory effect on S180 sarcoma growth and its effect on Bcl-2 expression in tumor-transfected mice. Methods S180 cells were subcutaneously injected into 60 healthy Kunming mice. Meanwhile the mice were dealt with MTX or Baizhu, separately; the weight of tumor was measured in the following two weeks; the expression of Bcl-2 was detected by RT-PCR. Results The tumor's weight in Baizhu group was lower than that in model group, but higher than in MTX group (P<0.05), but Baizhu's inhibition was not associated with its dose (P>0.05), and Baizhu's rate of tumor growth inhibition was lower than that of MTX. Compared with that in control group, Bcl-2 expression was lower in Baizhu group obviously. Conclusion Baizhu can inhibit tumor growth and serve as an adjuvant drug in tumor therapy.
