【摘要】 用MTT试验方法比较49种单体结构激光光敏剂的光动力学效应，结果显示50％肿瘤细胞抑瘤率位于前10位的单体光敏剂结构以血卟琳类为主，目前临床上试用的光敏剂血卟啉类单甲醚PSD-007处第17位。MTT方法用于筛检多种光敏剂具有简便，快速和数据可靠的优点。更多还原

【Abstract】 The comparative test was performed among 49 single photosensitizers. The ranks of the first ten effectives were mainly the kinds of hematoporphyrins,whicn were inhebited more than 50% tumor cells. The photosensizer, PSD-007, which has been already used in clinical test,was ranked at 17th. MTT assay is a speedy and efficent metnodor com paring photosentizers.更多还原
