1、JournalofChineseOncology,2014,Vol.20,No.1冬凌草甲素对C6大鼠脑胶质瘤裸鼠异种移植模型的抗肿瘤疗效研究尹波,李志伟,张弩,盛汉松,林坚(温州医科大学附属第二医院,浙江温州325000)摘要:[目的]利用C6大鼠脑胶质瘤裸鼠异种移植模型研究冬凌草甲素对大鼠C6脑胶质瘤增殖的抑制效果。[方法]应用C6大鼠脑胶质瘤细胞株建立了该肿瘤的BALB/C裸鼠异种移植模型,腹腔注射低、中、高3个剂量的冬凌草甲素和固定剂量的对照化疗药物卡氮芥,比较给药前后的相对肿瘤增殖率、肿瘤抑制率和肿瘤体
2、积变化,单因素方差分析比较各组间差异。[结果]在给药后的22d,冬凌草甲素低、中、高3个剂量组所对应动物模型的相对肿瘤增殖率均小于100%,且随着冬凌草甲素给药剂量的增加而降低;肿瘤抑制率均为正值,且随着给药剂量的增加而升高,但3个剂量组之间差异无统计学意义(F=7.59,P>0.05);在给药后的22d内,未给药组和所有给药组动物模型体内的肿瘤体积均呈逐日增大的趋势,但在12d后,高剂量冬凌草甲素给药组动物模型的肿瘤体积增量要显著小于未给药组(F=41.15,P<0.05),在给药组中,随着给药剂量的增加,在同
3、一天动物模型所对应的肿瘤体积增量呈现递减趋势。[结论]冬凌草甲素对大鼠C6脑胶质瘤的增殖具有一定的抑制效果。主题词:冬凌草甲素;卡氮芥;胶质瘤;异种移植中图分类号:R739.41文献标识码:A文章编号:1671-170X(2014)01-0034-06doi:10.11735/j.issn.1671-170X.2014.01.B008Anti-tumorEfficacyofOridonintoRatC6GliomainNudeMouseXenograftModelYINBo,LIZhi-wei,ZHANGNu,e
