مستخلص: | The aim of this study was to evaluate the lethal potential of macrophages infected with Staphylococcus aureus after PACT (Photochemical Antimicrobial Chemotherapy) using phenothiazine derivatives (a solution containing 1:1 methylene blue and O toluidine blue) and laser (660 nm, 40 mW, 60 s, 12 J/cm 2 ) or LED (632 ± 2 nm, 145 mW, 40 s, 12 J/cm 2 ). Six experimental groups were evaluated: Control Group (untreated); Photosensitizer group (phenothiazines - 12.5 μg/mL); Laser Group; LED Group; Laser PACT Group; and LED PACT Group. The pre-irradiation time used in this study was 5 min. Macrophages and bacteria were cultured in specific culture media and/or allowed interaction between the cell types. Subsequently, tests were carried out to evaluate microbial proliferation, ROS production by macrophages and survival capacity of S. aureus after phagocytosis. Fluorescence microscopy assays were performed with the H (Copyright © 2018 Elsevier B.V. All rights reserved.) |
