酸硝甘油是一种具有一定毒性的化合物。任何一种毒物对于一个母亲来说,只要她在怀孕期间接触了该种化合物并吸收了一定的剂量,都可导致对胎儿的危害。就硝酸甘油而言,大剂量硝酸甘油对机体的明显的毒性作用是在机体内形成高铁血红蛋白。硝酸甘油能破坏职业接触者血液里血红蛋白分子中红细胞的正常还原机制和血红蛋白中铁元素的氧化作用。目前已有不少资料表明:环境中的硝酸甘油暴露更易导致婴儿体内血液中产生高铁血红蛋白。专家认为:这种作用可能与在胚胎期间血红蛋白中的
Nitroglycerin is a toxic compound. Any kind of poison for a mother, as long as she came into contact with the compound during pregnancy and absorbed a certain dose, can cause harm to the fetus. In the case of nitroglycerin, the apparent toxic effect of high doses of nitroglycerin on the body is the formation of methemoglobin in the body. Nitroglycerin can destroy the normal reduction mechanism of red blood cells in hemoglobin in the blood of occupational contacts and the oxidation of iron in hemoglobin. There are a lot of data to show that nitroglycerin exposure in the environment can easily lead to methemoglobin in the blood of infants. Experts think: This role may be related to hemoglobin during embryo
