Photoprotective Effect of the Plant Collaea argentina against Adverse Effects Induced by Photodynamic Therapy
Figure 3
Photoprotective assays of C. argentina extract against ALA-PDT in LM2 cells. ALA-PDT was performed employing 0.6 mM ALA, 3 h of incubation, and different irradiation times. ((a)–(e)) correspond to the different protocols employed, as explained in Section 2. Cell viability was expressed as percentage of the control without irradiation.
