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.
