The results showed that the decomposition of 4-nitroimidazole began with the split of the C—NO2 bond in the temperature range of 185—210℃. The strongly oxidative product NO2 destroyed the instable annulus of 4-nitroimidazole instantly, all the other C＝N, C＝C, C—H and N—H bonds of the five membered ring were broken simultaneously, and the detected gas products of 4-nitroimidazole decomposition were NO2, CO2 and CO.

结果表明，4-硝基咪唑的催化热分解起始于其分子中C-NO2化学键的断裂，温度范围是185~210℃。C-NO2键的强氧化性的裂解产物NO2瞬间作用于4-硝基咪唑分子中不稳定的五员环，使化学键C=N、C=C、C-H和N-H同时被打破。4-硝基咪唑的气体分解产物包括NO2、CO2和CO。

METHODS: The oxidative damages of erythrocyte induced by CSE were evaluated through biochemical assays of malonaldehyde, methemoglobin and reduced glutathione levels, hemolytic rate, SDSPAGE of membrane proteins and chromatographic analysis of membrane phospholipids.

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。

While erthrocyte, hemoglobin and Hela cell were under oxidative damage induced by the hydrogen peroxide (H2O2) or tert-butyl hydroperoxide on different concentrations of dihydromyricetin, hemolysis rate of erythrocyte and methemoglobin converted from hemoglobin was estimated by ultraviolet-visible absorption spectroscopy. Whereas mmalondialdehyde from erythrocyte was measured by thiobarbituric acid colorimetry, the cellular viability of Hela cell was examined using MTT 3-(4, 5-dimethylthiazol-2-yl-2, 5-diphenyl tetrazolium bromide assay.

在不同的二氢杨梅素浓度下，用过氧化氢或过氧化特丁烷对红细胞、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，硫代巴比妥酸法测定红细胞中的丙二醛，MTT法检测Hela细胞的活力。
