methylene blue

 [meth´ĭ-lēn]
a synthetic organic compound, in dark green crystals or lustrous crystalline powder, used in treatment of methemoglobinemia, as a stain in pathology and bacteriology, and as a diagnostic aid in the detection of the premature rupture of fetal membranes.

meth·y·lene blue

(meth'ĭ-lēn blū), [C.I. 52015]
A basic dye easily oxidized to azure with dye mixtures; used in histology and microbiology to stain intestinal protozoa in wet mount preparations, to track RNA and RNase in electrophoresis, and as an antidote for methemoglobinemia; its redox indicator properties are useful in milk bacteriology.

methylene blue

n.
A heterocyclic aromatic compound, C16H18N3SCl·3H2O, consisting of dark green crystals that form a deep blue solution when dissolved in water. It is used as an antidote for cyanide poisoning, an analytical indicator, and a bacteriological stain.

methylene blue

Alternative oncology
A synthetic bacteriostatic dye that inhibits the growth of several experimental cell lines, which has been proposed as a therapy for certain cancers; used in combination with phototherapy, it may be useful for superficial bladder cancer.

meth·y·lene blue

(meth'i-lēn blū)
A basic dye easily oxidized to azure, with dye mixtures; used in histology and microbiology, to stain intestinal protozoa in wet-mount preparations, to track RNA and RNase in electrophoresis, and as an antidote for methemoglobinemia; its redox indicator properties are useful in milk bacteriology.

methylene blue

A solution of methylthioninium chloride that has been used to treat METHAEMOGLOBINAEMIA. It is also used as a bacterial stain and sometimes in surgery to demonstrate fistulas. The drug is on the WHO official list.

Methylene blue
