ENHANCED ANTI-MICROBIAL PDT

摘要

Present invention provides enhanced methods and improved devices to eliminate, reduce, destroy and/or inhibit undesired body fluid species, such as pathogen microbes and deteriorated or malignant cells in complex environments like blood, serum and other body fluids. In preferred embodiments, present invention provides an antimicrobial PDT treatment and devices that effectively inactivates, reduces and/or destroys both Gram (-) and Gram (+) bacteria in complex body fluids. Preferred device embodiments comprise guiding channels and at least one electromagnetic radiation source, arranged separately or in sequence. Preferably, laser device or LED-panels are used to deliver electromagnetic radiation to activate the photosensilizer. Electromagnetic radiation is preferably delivered intermittently with pulse width based on treatment parameters. When used with preferred photosensitizer composition based on Safranin O, preferred laser radiation wavelength is in the range of 500-580nm. Additionally, present invention diminishes adverse host's inflammatory responses by neutralizing the biological activity of pathogenic microorganism fragments and reducing and/or removing pathogenic microorganism fragments responsible for it.
