OBJECTIVE Sentinel lymph node biopsy is the recommended approach in the evaluation of axilla during breast cancer surgery. In this study, results of patients who underwent methylene blue sentinel lymph node biopsy were evaluated. MATERIALS AND METHODS The study included 32 female patients with T1 and T2 tumors. 5 ml of 1% methylene blue was injected into the peritumoral area or around the cav...

The study has focused on the development of a treatment technique and method for dye wastewater, such as an oxidation reduction process. The potentiochromic study of voltage sensitive methylene blue dye was performed in acidic medium at carbon electrodes. It was found that the carbon electrode shows sensitivity and durability for the retardation of dye. From the results it is revealed that the ...

Dyes such as batik dyes and the textile industry can pollute enviroment, especially receiving water bodies. The use of pineapple biomass waste an adsorbent for removal (methylene blue). Adsorption experiment using were varied in dose, contact time stirring speed. In this study, used consisted pure activated biomass. experimental result showed that masses into 0,5,1,2,5,3, dan 3,5 gr 250 mg/L gl...

Since 1990 avoidance of methylene blue as a dye in diagnostic amniocentesis is recommended. This is a result of the observation that a high incidence of jejunoileal atresia appeared in twin pregnancies following intraamniotic injection of methylene blue. We report four further cases of jejunoileal atresia in twins after intraamniotic injection of dyes since 1991. We describe the clinical course...

Stroke is a leading cause of death and long-term disability. Methylene blue, a drug grandfathered by the Food and Drug Administration with a long history of safe usage in humans for treating methemoglobinemia and cyanide poisoning, has recently been shown to be neuroprotective in neurodegenerative diseases and brain injuries. The goal of this paper is to review studies on methylene blue in expe...

oxidase 3 . Moreover, methylene blue was shown to be a strong inhibitor of the overall reaction. Oneelectron acceptors are also ineffective with the Dspecific enzyme; however, methylene blue and 2.6dichlorophenol-indophenol are able to reoxidize the reduced D-6-hydroxynicotine oxidase. In the presence of these dyes the rates of the overall process are higher than those with oxygen. Anaerobic ti...

Recently while experimenting with solutions of various dye stuffs on kala-azar serum, we observed that when solutions of methylene blue were left in contact with kala-azar serum, the dye gradually decolourised. We have tried out various strengths of methylene blue solutions varying from 1 in 2,000 to 1 in 80,000 and obtained the most satisfactory results when working with a solution of 1 in 40,...

We have analyzed the in vitro activities of pyronaridine and methylene blue against 59 Plasmodium falciparum isolates from Kenya in association with polymorphisms in Pfcrt (codon 76), Pfmdr1 (codon 86), and Pfnhe (full sequence). The median inhibitory concentrations that kill 50% of parasites were 13.5 and 3.3 nM for pyronaridine and methylene blue, respectively. Their activities were not assoc...

Increase of methemoglobin level is named as methemoglobinemia characterized by functional anemia and tissue hypoxia. Methemoglobinemia can be congenital, but acquired form are more often caused by various drugs and toxins. Methylene blue is the most effective antidote for acquired methemoglobinemia. When methylene blue is not available, alternative treatments such as ascorbic acid and hyperbari...
