摘    要:目的:探讨复方苦参液对大肠癌裸鼠皮下移植瘤的抑瘤情况及相关作用机制。方法:30只裸鼠建立大肠癌皮下移植瘤动物模型,随机分为3组:空白对照组(注射生理盐水)、低浓度治疗组和高浓度治疗组.观察3组第3,7,14,21日皮下移植瘤生长情况及裸鼠体质量的变化;治疗结束时取肿瘤组织及心、肝、肺、肾等行病理组织学检查,免疫组化法检测增殖细胞核抗原(PCNA)和CD34,TUNEL法检测细胞凋亡情况。结果:复方苦参液对裸鼠移植瘤的生长有明显抑制作用,与对照组相比,瘤体质量明显降低、体积减小(P〈0.05),坏死面积显著增加,细胞增殖降低(P〈0.05),血管生成减少(P〈0.05),凋亡指数明显升高(P〈0.05),但对裸鼠体质量无明显影响,心、肝、肺、肾等组织未见明显病理学改变。结论:复方苦参液具有抑制入大肠癌裸鼠皮下移植瘤生长的作用,可能与其抑制血管生成和诱导细胞凋亡有关。

关 键 词:结直肠肿瘤  苦参碱  小鼠    增殖细胞核抗原  细胞凋亡
