简介:摘要目的探讨熊果酸抗肿瘤对小鼠肿瘤生长和肺转移的作用。方法建立60只荷H22肝癌小鼠模型,并将60只实验小鼠平均分为试验1组、试验2组,给予试验1组小鼠熊果酸灌胃,给予试验2组小鼠环磷酰胺灌胃,灌药周期均为两周,末次灌药24小时后,将两种试验小鼠处死,称量小鼠肿瘤病灶质量,对小鼠肿瘤病灶进行病理学检查。结果经称量得出试验1组小鼠肿瘤质量明显轻于试验2组小鼠(P<0.05),病学检查结果显示试验1组小鼠的肿瘤细胞数量明显少于试验2组小鼠(P<0.05),试验1组小鼠的肿瘤肺转移发生率为10.0%,低于试验2组小鼠的30.0%。结论熊果酸能够抑制荷H22肝癌小鼠肿瘤生长和转移。
简介:摘要目的观察槲皮素对卵巢癌细胞生长的影响,为寻找治疗卵巢癌的新药物提供实验依据。方法运用细胞培养、光镜观察及MTT法测定细胞活性等方法,对比卵巢癌细胞在槲皮素作用不同时间后的生长情况和细胞活性,探讨槲皮素对卵巢癌细胞生长的影响。结果加入50μmol/L槲皮素后,卵巢癌细胞的生长受到明显的抑制,且呈时间依赖性。结论槲皮素能够抑制卵巢癌细胞的生长。
