美蓝也叫亚甲蓝、甲烯蓝,化学名称为氯化四甲基硫堇,是一种氧化还原剂,对血红蛋白有两种作用。在高浓度时,使血红蛋白的亚铁氧化为高铁,生成高铁血红蛋白;相反,在低浓度时,可使高铁血红蛋白还原为血红蛋白。正常健康者,也有少量高铁血红蛋白,但大部分血红蛋白内含二价铁,所以能完成正常携带氧和释放氧的功能,这少量的高铁血红蛋白通过体内酶的作用,能还原为低铁血红蛋白。因此,正常情况下,血中不
Methylene blue, also known as methylene blue, methylene blue, the chemical name of tetramethylthioninium chloride, is a redox agent, hemoglobin has two roles. At high concentrations, hemoglobin is oxidized to ferrous iron to produce methemoglobin; in contrast, methemoglobin is reduced to hemoglobin at low concentrations. Normal healthy people, but also a small amount of methemoglobin, but most of the hemoglobin contains ferrous iron, it can complete the normal carrying oxygen and oxygen release function, this small amount of methemoglobin hemoglobin through the body’s role in the body can be reduced to methemoglobin. Therefore, under normal circumstances, the blood does not
