INTRODUCTION Methylene blue dye has been used worldwide successfully with few complications in breast surgery. We present two different complications involving methylene blue: 1) skin and parenchymal necrosis when dye was injected in a subdermal fashion and 2) Mycoplasma infection caused by contaminated methylene blue in breast reduction surgery. METHODS We present two cases seen at the Unive...

According to Franke (l), the occurrence of a green color following addition of solutions of methylene blue to fluids containing bilirubin first was described by Chetchowski in 1897. It has provided the basis for a simple method of testing for bile pigment in urine and recent reports have reaffirmed its value for this purpose (2-5). The explanation for the color effect has long been a subject of...

BACKGROUND Photodynamic therapy is a therapeutic modality that has consolidated its activity in the photooxidation of organic matter, which arises from the activity of reactive oxygen species. OBJECTIVE To evaluate the effect of red laser 660nm with the photosensitizer methylene blue on Propionibacterium acnes in vitro. METHOD The experimental design was distributed into four groups (1 - co...

Methylene blue is a phenothiazine-related heterocyclic aromatic molecule presently used in the treatment of methemoglobinemia. Recently, it has been implicated in the treatment of severe refractory vasoplegic shock caused by anaphylaxis, sepsis, or postcardiopulmonary bypass. We present a case of a 27-year-old male with profound vasoplegic shock of unknown etiology which was refractory to vasop...

background and objectives : due to the extensive use of antibiotics, the spread of drug-resistant bacteria is one of the most worrisome threats to public health. one strategy that can be used to overcome potential shortcomings might be the inactivation of these organisms by photodynamic therapy. in this study, we have investigated whether drug-resistant wound-associated organisms (staphylococcu...

A sensitive and selective kinetic-spectrophotometric method is proposed for the determination of microg mL(-1) amounts of Cu2+ based on its catalytic effect on the oxidation of L-ascorbic acid by Methylene Blue in a strongly acidic medium. The reaction is monitored spectrophotometrically by measuring the decrease in color intensity of Methylene Blue at 665 nm. The analysis of Cu2+ ion is perfor...

Green synthesis is a potential method and increasingly popular for synthesizing nanoparticles. In this study, iron nanomaterial was green sythesized using Cleistocalyx operculatus leaves extract as reducing agent. Morphology structure of the as-prepared characterized by scanning microscope, X-ray diffraction analysis methods. The collected product nano material with morphology paticles diameter...

the reduction capacity of ammonia while present even at ppm level can be demonstrated by the increased encounter probability between ammonia and methylene blue dye (mb+) incorporated in nanomordenite and na-mor zeolites. the rate of reduction methylene blue dye by ammonia on the surface nanomordenite zeolite is faster than na-mordenite (na-mor) zeolite.because nanomordenite zeolite with high si...
