Abstract
目的:观察温下方对Lewis肺癌的抑制作用及对细胞周期的影响.方法:C57BL/6小鼠皮下接种Lewis肺癌,随机分组,口服给药后计算抑瘤率、脾及胸腺指数;流式细胞技术分析肿瘤细胞周期变化及凋亡百分率.结果:温下方质量分数在生药2.8、5.57和11 g/(kg·d)时,对小鼠Lewis肺癌的抑制率分别为31.0%、34.3%和37.6%;肺癌细胞凋亡率增加至(11.13±4.52)%、(16.31±6.12)%和(20.08±5.13)%;G0/G1期细胞比例增加至(50.40±5.37)%、(56.01±5.91)%和(62.38±5.22)%,呈明显的剂量依赖关系.结论:温下方抑制肿瘤生长的机制可能与阻滞细胞周期、诱导细胞凋亡有关.
