查询词典 methaemoglobin

NOS also reflect the generation of NO, NOS was measured by a method which the oxidation of oxyhaemoglobin to methaemoglobin by NO is monitored spectrophotometrically. The absorption difference between 401 and 421nm was continuously monitored with a dual-wavelength recording spectrophotometer.

由NOS催化生成的NO与氧合血红蛋白反应生成高铁血红蛋白，反应2秒钟完成同时出现A〓和A〓吸光度的变化，测定该变化，根据此时高铁血红蛋白的摩尔吸光系数即可计算出NOS的比活性。

Methaemoglobin loses its ability to bind oxygen and causes hypoxia in the affected individuals. The condition is characterized by headache, weakness and breathlessness, and a bluish discolouration of the skin and mucous membranes called cyanosis.

这是因为亚硝酸盐使体内红血球素中的铁由亚铁氧化成正铁，正铁血红蛋白失去携氧能力，造成血氧过少，令人感到头痛，虚弱，呼吸困难，皮肤和黏膜会变成紫蓝色，医学上称为发绀。
