methylene blue

 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.

Sorptive properties of a natural mineral glauconite towards methylene blue were studied and a composite of both substances was obtained. Antibacterial activity of the composite has been assessed against Staphylococcus aureus FDA 209P. An enriched fraction of natural glauconite was obtained by method of magnetic separation. Surface morphology of the glauconite was examined with scanning electron microscopy. The elemental composition was investigated using energy-dispersive microanalysis and roentgen fluorimetry, the texture – using Brunauer–Emmett–Teller analysis.
