5) methemoglobin
[英][met'hi:mə,gləubin] [美][mɛt'himə,globɪn]
高铁血红蛋白
1.
METHODS: The oxidative damages of erythrocyte induced by CSE were evaluated through biochemical assays of malonaldehyde (MDA), methemoglobin (MetHb) and reduced glutathione (GSH) levels, hemolytic rate, SDS-PAGE of membrane proteins and chromatographic analysis of membrane phospholipids.
方法:以市售香烟提取CSE,然后作用于红细胞,通过测定细胞溶血率、膜脂质过氧化水平、细胞内高铁血红蛋白以及还原谷胱甘肽含量、膜磷脂组成和膜蛋白谱变化等指标,对CSE导致的红细胞膜损害进行评估。
2.
While erthrocyte,hemoglobin and Hela cell were under oxidative damage induced by the hydrogen peroxide(H_2O_2) or tert-butyl hydroperoxide(TBHP) on different concentrations of dihydromyricetin,hemolysis rate of erythrocyte and methemoglobin converted from hemoglobin was estimated by ultraviolet-visible absorption spectroscopy.
在不同的二氢杨梅素浓度下,用过氧化氢或过氧化特丁烷(TBHP)对红细胞、血红蛋白和Hela细胞进行氧化伤害,以紫外-可见光分光光度法检测红细胞溶血率和由正常血红蛋白生成的高铁血红蛋白,硫代巴比妥酸(TBA)法测定红细胞中的丙二醛(MDA),MTT法检测Hela细胞的活力。
3.
4-(N, N-dimethyl)-aminophenol (4-DMAP), an effective methemoglobin forming agent, is widely used for therapy of acute cyanide poisoning at the present time.
4-DMAP的抗氰作用源于其氧化生成的高铁血红蛋白,但当高铁血红蛋白浓度超过50%将引起高铁血红蛋白血症。
6) MetHb
高铁血红蛋白
1.
[Results]The rates of neurasthenia,decrease of white blood cells and hemoglobin and the average level of MetHb were siginificantly higher in the exposure group than in the control group(P﹤0.
[结果]接触组神经衰弱症状、白细胞和血红蛋白偏低率、高铁血红蛋白平均含量均显著高于对照组(P﹤0。
2.
Yet, such solution is unstable; there are marked rise in MetHb content and visible change in molecular distribution upon storage.
但这类溶液不稳定，保存过程中伴随着高铁血红蛋白(Methemoglobin MetHb)含量增加，同时观察到分子量改变。
3.
Oxyhemoglobin is intrinsically unstable, and it oxidizes readily to methemoglobin (MetHb).
血红蛋白(Hemoglobin，Hb)的自身氧化以及血红蛋白与氧自由基(O_2~-)和过氧化氢(H_2O_2)的反应都会产生高铁血红蛋白(Methemoglobin，MetHb)。
补充资料：高铁血红蛋白测定
高铁血红蛋白测定
methemoglobin test
检测高铁血红蛋白的定性试验。正常血红蛋白可与空气中的氧结合成为氧合血红蛋白，呈鲜红色；又可和氧分离成为还原血红蛋白，呈暗红色。高铁血红蛋白不能与氧结合，呈棕色，但其能被氰化钾还原成氧合血红蛋白而变成鲜红色。根据高铁血红蛋白的这一特性可用分光镜法和化学反应法进行测定。
