photosensitizers

Antimicrobial phototherapy is an alternative method for combating clinically signifi cant microorganisms associated with lesions of the skin, mucous membranes of the oral cavity, respiratory, gastrointestinal and urogenital tracts. The method uses non-toxic dyes called photosensitizers, molecules that can be excited by harmless visible light to form reactive oxygen species.

Cancer of the stomach is the main cause of death among cancer diseases of the gastrointestinal tract. This is due to the late diagnosis. This study was aimed at developing new methods for diagnosis of gastric cancer using a photosensitizer 5-ALK / PIXIX. The experiments were carried out on white non-native rats with an average mass of 250 grams. The animals were divided into 2 groups: control and experimental (stress + nitrosamine diet).

Antimicrobial phototherapy is an alternative method for combating clinically signifi cant microorganisms associated with lesions of the skin, mucous membranes of the oral cavity, respiratory, gastrointestinal and urogenital tracts. The method uses non-toxic dyes called photosensitizers, molecules that can be excited by harmless visible light to form reactive oxygen species. Numerous studies of the method in vitro and in vivo have demonstrated the destruction of microorganisms or a signifi cant reduction in their number.
