Methods: One hundred and fifty mice were randomly divided into five groups to observe the effect on tumor growth after H22 cancer cells had been transplanted subcutaneously into their right armpit region and treated with different dosages (5 mg/kg, 2. 5 mg/kg and 1. 25 mg/kg) of BP for 14 days, with Mi-tomycin (Mit-C) used as control. Another 150 mice were randomly divided into three groups, models of tumor metastasis in the lung by various paths (lymphatic, blood circulatory and spontaneous) were established respectively. They were treated with BP or Mit-C to observe the influence of treatments on tumor metastasis by various paths. Results: BP of various dosages showed no effect on tumor growth, but in high and middle dosage, it could significantly reduce the number or metastasis nodules ( P<0. 05). Conclusion: BP has a tumor metastasis inhibitory effect, which might be one of the candidates for new anti-tumor metastasis agents. Its mechanism may be blocking the function of platelets in the tumor metastasis progress.展开更多
目的:探讨罗勒多糖对荷NuTu-19卵巢癌大鼠模型的作用。方法:建立荷NuTu-19卵巢癌大鼠模型,体内观察罗勒多糖对荷瘤大鼠肿瘤生长及转移行为的影响,取大网膜瘤组织,提取总RNA,经逆转录、荧光标记后与R 20 s大鼠表达谱芯片杂交,经Gene P ix...目的:探讨罗勒多糖对荷NuTu-19卵巢癌大鼠模型的作用。方法:建立荷NuTu-19卵巢癌大鼠模型,体内观察罗勒多糖对荷瘤大鼠肿瘤生长及转移行为的影响,取大网膜瘤组织,提取总RNA,经逆转录、荧光标记后与R 20 s大鼠表达谱芯片杂交,经Gene P ix Pro 3.0图像处理软件分析。同时取肿瘤组织,进行常规病理学检测。结果:罗勒多糖处理组肿瘤的数量明显少于对照组,肿瘤体积小于、腹水量显著少于对照组(P<0.05);腹腔脏器转移程度积分与对照组有显著差异(P<0.01);同时采用表达谱芯片技术从药物组肿瘤组织中比较筛选出了268条差异表达基因。结论:罗勒多糖可能是一种抗卵巢癌转移的新型中草药,它对卵巢癌显现的独特效果可能是多个药效靶点综合作用的结果,本研究也显示了表达谱芯片技术在药物效应靶点研究中的优势和价值。展开更多
