Antifungal effects of low level laser on Candida species with using Methylene blue and toluidine blue dayes
Introduction: Oral Candidiasis is the most common lesion in Immuno compromised patients. Using antifungal drugs are routine treatment for this condition. The aim of this study was incorporating photodynamic therapy with low level laser (685 nm), in presence of 2 dyes (methylene blue and tolidine blue), as a photosensitizer on C. albilcans, C. glabrata. C. krusie and C.tropicalis. Methods...
متن کاملToluidine blue O and methylene blue as endothelial redox probes in the intact lung.
There is increasing evidence that the redox activities of the pulmonary endothelial surface may have important implications for the function of both lungs and blood. Because of the inherent complexity of intact organs, it can be difficult to study these activities in situ. Given the availability of appropriate indicator probes, the multiple-indicator dilution (MID) method is one approach for de...
متن کاملIn vitro lethal photosensitization of S. mutans using methylene blue and toluidine blue O as photosensitizers.
The purpose of this in vitro study was to evaluate the antimicrobial effect of photodynamic therapy on Streptococcus mutans (A TCC 25175) suspensions, using a red laser for one minute in combination with toluidine blue O (TBO) or methylene blue (MB). Both photosensitizers were used in three concentrations (25, 10 and 5 mg/L). The activity ofphotosensitizers and laser irradiation were tested sep...
متن کاملSusceptibility of Candida albicans to photodynamic therapy using methylene blue and toluidine blue as photosensitizing dyes.
The increased resistance of Candida albicans to antibiotic therapy indicates the need for alternative treatments for oral candidiasis. Photodynamic therapy (PDT) has been researched as an alternative tool to inactivate pathogenic microorganisms. It uses a combination of a photosensitizer and a visible light source. This study evaluated the susceptibility of C. albicans to PDT and compared the e...
متن کاملStabilized with Methylene Blue
The in vitro viability, chemotaxis, and labeling stability of leukocytes labeled using 99mTc-exametazime stabilized with methylene blue were evaluated and compared with those obtained using nonstabilized 99mTc-exametazime. Methods: Two identical leukocyte populations, from 30 healthy donors, were labeled simultaneously using freshly prepared and 2-h-old stabilized 99mTc-exametazime. The followi...
