антибактериальная фотодинамическая терапия

Photodynamic treatment using led red (660 nm) and laser infrared (808 nm) radiation for the treatment of simulated abdominal abscesses in laboratory animals

 This study examined the eff ectiveness of antimicrobial photodynamic therapy (APDT) in the treatment of simulated purulent abdominal abscesses in laboratory animals. Two “radiation + photosensitizer” regimens were tested: 1) using red LED (660 nm) radiation and methylene blue, 2) using laser infrared (808 nm) radiation and indocyanine green.

Ex vivo model of using the method of optical skin clearing during antimicrobial photodynamic action

This study evaluated the effi cacy of transcutaneous photodynamic therapy using blue (428 nm) LED irradiation on Staphylococcus aureus 11 in combination with a water-soluble cationic pyridyl porphyrin and optical clearing agents (OCA) in an ex vivo model. Results showed that OCA signifi cantly enhanced photodynamic inactivation with a 61% reduction in bacterial cell counts after 15 minutes of light exposure, comparable to direct irradiation.
