Fig 7. Effect of PDT on cells of subcutaneous tumors in the ICG-treated and ICG-lactosome-treated mice.

Fig 7

Tumors were obtained for examination of apoptosis at 24 h after irradiation (500 mW/cm2 and 200 s, 100 J/cm2) in the ICG (A) and ICG-lactosome (B) groups. TUNEL staining was performed on the specimens. (C) Apoptotic indexes in the ICG-treated and ICG-lactosome-treated mice with subcutaneous tumors. P = 0.001 between the ICG and ICG-lactosome groups; n = 5/group.
