Results The strongest photoinactivation effect occured in the HEP-2 cells co-cultured with 1 mmol/L ALA for 8 h. The killing activity of ALA-PDT to the HEP-2 cells was positively correlated with the power density of the irradiation (r=0.88, P＜0.05).Conclusions ALA-PDT can effectively kill the cultured HEP-2 cells in vitro. The optimal killing activity was related to the time and the power density of the laser irradiation.

结果 (1)光照时机选择在ALA与HEP-2细胞培养8 h时杀伤效应最强；(2)ALA-PDT对HEP-2细胞的杀伤效应与照光能量呈正相关r=0.88，P 结论 ALA-PDT能有效地杀伤体外培养的肿瘤细胞，其杀伤最佳效果与照光时机和照光能量有关。
