ABST RACT Introduction: This study sought to determine the utility of the methylene blue test for evaluating esophagojejunostomy anastomosis. Materials and Methods: The study analyzed 65 patients with gastric cancer who underwent total gastrectomy and esophagojejunostomy anastomosis. The patients were divided into two groups. In Group A (n= 30), methylene blue was used to evaluate the esophagoj...

1. The respiratory metabolism of non-nucleated mammalian erythrocytes is enormously accelerated and approaches the magnitude of the metabolism of the nucleated erythrocytes of birds on the addition of methylene blue (and certain other dyes), to a final concentration of 0.005-0.0005 per cent. 2. In the presence of methylene blue the respiration is accelerated even when M/1000 KCN is also present...

BACKGROUND Methylene blue is widely used in the medical field, especially as a blue dye for staining. It is also used as a photosensitizing agent in antimicrobial photodynamic therapy, which once photoactivated is effective for the eradication of several multi-resistant bacteria. The objective of this study was to investigate the ototoxic potential of methylene blue and precise its use in otolo...

To report a case of methylene blue related endophthalmitis. Observational case report. Review of clinical record, photographs. A 60 year old man developed endophthalmitis after methylene blue was accidentally used to stain the anterior capsule during phacoemulsification of cataract. His left visual acuity deteriorated from 6/12 to 6/36 two weeks after the operation. Despite intensive treatment ...

This article presents the development and characterization of nanoparticles loaded with methylene blue (MB), which are designed to be administered to tumor cells externally and deliver singlet oxygen ('0,) for photodynamic therapy (PDT), i.e. cell kill via oxidative stress to the membrane. We demonstrated the encapsulation of MB, a photosensitizer (PS), in three types of sub-200 nm nanoparticle...

Carbon-coated TiO2 catalysts were found to have high photocatalytic activity for photodecomposition of methylene blue in water, higher than TiO2 without carbon coating [1]. However, these catalysts used for phenol decomposition showed lower activity than TiO2 without carbon coating. Also lower adsorption capacity of phenol on carbon-coated TiO2 catalysts was noted by comparison with adsorption ...

OBJECTIVE To evaluate the value of microarthroscopy in the equine midcarpal joint using the vital stains methylene blue, trypan blue, neutral red, and Janus green B to observe components of the synovial lamina propria, vascular architecture, and synoviocytes. STUDY DESIGN Experimental. ANIMALS Ten horses. METHODS Microarthroscopy of left and right midcarpal joints was performed with and w...

The study of Methylene Blue penetration in both skin and subcutaneous fat is presented. Experiments have been carried out with both rat skin and human adipose tissue in vitro at room temperature. Microscopic analysis with digital imaging system has been applied for visualizing and investigation of the Methylene Blue diffusion in the epidermal, dermal and adipose tissue. Diffusion coefficient of...

The study showed the effectiveness of photodynamic therapy based on methylene blue to treat severe distal and lateral subungual toenail onychomycosis. 22 patients were divided into two groups: group A consisting of 11 patients with severe toenail onychomycosis and group B consisting of 11 patients with mild-to-moderate toenail onychomycosis. All patients had onychomycosis caused by Trichophyton...
