简介：目的马尾藻类海草wightiiGreville是属于有大约200种类的Sargassaceae家庭的海洋的棕色的水藻。整个干燥植物粉末的ethanolic摘录包含了众多的phytoconstituents，包括flavonoids。学习在老鼠集中于马尾藻类海草wightii的anticancer活动。在二剂量的马尾藻类海草wightii(EESW)的ethanolic摘录铺平的方法被用来用DAL房间线在老鼠检验anticancer活动导致癌症。身体重量，可行、不能生存的肿瘤房间计数，吝啬的幸存时间，寿命的增加，和hematological参数为EESW的anticancer活动被观察。在老鼠的DAL房间的intraperitoneal接种显著地增加了的结果癌症房间计数。在在对待EESW的组癌症动物观察的癌症细胞数字的减少显示测试药在肿瘤细胞增长上有重要禁止的效果。有EESW的治疗也在肿瘤重量显示出重要减少，并且因此增加了对待DAL的老鼠的lifespan。另外，EESW管理显著地在对待DAL的老鼠恢复了hematological参数。现在的学习结果建议摘录提议的那个政府的结论提高了抗氧化剂潜力。因此，EESW拥有anticancer活动，这能从这研究被结束。

简介：目的：研究莪术醇对小鼠皮肤黑色素瘤B16-F10细胞凋亡的影响。方法：采用四氮唑盐（MTT）法检测不同浓度的莪术醇对B16-F10细胞增殖的影响;并用光学显微镜观察不同浓度的莪术醇对B16-F10细胞状态的影响;通过流式FITC-AnnexinV/PI双染法,检测不同浓度的莪术醇对细胞凋亡率的影响;通过间接荧光标记法检测不同浓度的莪术醇对细胞内活性氧水平的影响;通过罗丹明123染色,检测不同浓度的莪术醇对细胞内线粒体膜电位的影响。结果：不同浓度莪术醇处理B16-F10细胞24、48、72h,均可呈浓度、时间依赖性的抑制细胞增殖;显微镜观察到莪术醇可以引起细胞形态变圆,漂浮等细胞死亡现象。12.5、25、50、100μg/ml莪术醇作用48h后,诱导的细胞凋亡率分别为（19.5±3.4）%、（35.1±2.8）%、（45.9±4.1）%、（60.5±1.9）%,与对照组具有显著性统计学差异;诱导的细胞内活性氧水平的百分率分别为（6.9±1.8）%、（12.4±2.1）%、（20.9±3.1）%、（29.1±3.5）%,与对照组相比具有显著统计学差异。引起的线粒体膜电位的百分比分别为（40±1.1）%、（33.7±4.2）%、（27.3±2.5）%、（17.9±2.9）%,与空白对照组相比具有统计学差异。结论：莪术醇可以抑制B16-F10的增殖并促进细胞凋亡,其凋亡机制可能与细胞内活性氧组分的产生以及线粒体膜电位的变化有关。
