The methylene blue value is defined as the number of milliliter's standard methylene value solution decolorized 0.1 g of activated carbon (dry basis). [65] Methylene blue value reflects the amount of clay minerals in aggregate samples. [ 66 ]
Methylene blue is given as a 1% solution (10 mg/ml) 1 to 2 mg/kg administered intravenously slowly over five minutes. Although the response is usually rapid, the dose may be repeated in one hour if the level of methemoglobin is still high one hour after the initial infusion. Methylene blue inhibits monoamine oxidase, and serotonin toxicity can ...
The methylene blue allows the methaemoglobin to be converted to haemoglobin. Supportive treatment is also usually provided, depending on the severity of the toxicity, that resulted in the anaemia. [11] Ascorbic acid is used to treat methemoglobinemia, a symptom of naphthalene poisoning and is used when methylene blue is not available, or in ...
While the addition of methylene blue to treat cases of methemoglobinemia has been scientifically tested and proven, there are some side effects to note and monitor with high dosages of the antidote. Minor side effects include green or blue discoloration of urine; however, significant side effects include worsening of the present methemoglobinemia.
Dichloromethane (DCM, methylene chloride, or methylene bichloride) is an organochlorine compound with the formula C H 2 Cl 2. This colorless, volatile liquid with a chloroform-like, sweet odor is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents.

Allergic-like reactions and methemoglobinemia have been documented after the use of methylene blue dye in chromopertubation. [9] These reported symptoms vary from blue discoloration of body fluids to anaphylactic shock. [10] Methemoglobinemia is a blood disorder that can potentially result in various levels of cyanosis. [11]
Methyl blue is a chemical compound with the molecular formula C 37 H 27 N 3 Na 2 O 9 S 3.It is used as a stain in histology, [1] and stains collagen blue in tissue sections. It can be used in some differential staining techniques such as Mallory's connective tissue stain and Gömöri trichrome stain, and can be used to mediate electron transfer in microbial fuel cells.
Wright's stain is a hematologic stain that facilitates the differentiation of blood cell types. It is classically a mixture of eosin (red) and methylene blue dyes. It is used primarily to stain peripheral blood smears, urine samples, and bone marrow aspirates, which are examined under a light microscope.
