    ..Therefore, PDT with 10 microm Sylsens B (formulation I) and 18 J/cm(2) UVA-1 could be considered as effective and safe. This offers the possibility to perform clinical studies in future. ..

    ..We demonstrated that TPP was mutagenic using the Photo-SMART. For hematoporphyrin, the results of the Photo-SMART indicate the absence of mutagenicity. ..

    ..We conclude that T. rubrum is susceptible to PDT in a situation that mimics the clinical situation. The fungicidal effect of PDT on fungal spores is of particular importance. ..
