摘要:
目的初步探讨血卟啉单甲醚(HMME)介导的光动力疗法(HMME—PDT)联合紫杉醇(Frx)对人
宫颈癌Hela细胞的杀伤效应。方法将宫颈癌细胞株Hela分为6组,a:空白对照组,b:化疗组,e:饱和光动力组,dl:化疗+低剂量光敏剂组,d2:化疗+中剂量光敏剂组,d3:化疗+高剂量光敏剂组。MIT法检测细胞生长抑制率。结果d3组与a、b、c组及d1、d2组相比,差异均有显著性(P<0.01);dl、d2、d3各组之间相比,差异有显著性(P<0.05);b组及e组与a组相比,差异有显著性(P<0.05)。结论HMME—PDT联合紫杉醇对体外培养的人宫颈癌Hela细胞有明显的杀伤效应,有可能作为一种新的治疗手段应用于临床。关键词:宫颈癌;血卟啉单甲醚;光动力疗法;紫杉醇中图分类号:R711.74
