The carboxyhemoglobin levels in artery blood were detected with CO-oximeter and the expression of intercellular adhesion molecule-1 (ICAM-1) in the lung was detected by Western blotting.

应用一氧化碳血氧分析仪监测动脉血中碳氧血红蛋白水平的变化；应用Western blotting检测肺组织中细胞间粘附分子-1（ICAM-1）表达的变化。

The carboxyhemoglobin levels of in-flowing pulmonary blood and out-going pulmonary blood were determined at 2,4 and 6 hours after treatments. Malondialdehyde contents and superoxide dismutase activities in the lung,liver and blood were also determined. Pathological changes in lung and liver were examined with light microscope,and immunohistochemical technique was used for analysis of heme oxygenase-1 (HO-1) protein expression and distribution in lung and liver.

各组分别在制模后2、4和6 h测定出入肺血中碳氧血红蛋白水平；肺、肝组织及血液中丙二醛含量及超氧化物歧化酶活性；光镜下观察肺、肝组织形态学改变；免疫组化分析血红素加氧酶-1(HO-1)在肺、肝组织中的蛋白表达和分布。

Our experimental results imply that under high oxidative stress, the oxyhemoglobin tends to change to deoxyhemoglobin first and then to carboxyhemoglobin; the deformability of erythrocytes also instable under oxidative stress.

因此我们推论高氧化压力下，带氧血红素会先转变成去氧血红素再转变成一氧化碳血红素，且其变形能力会产生改变，而导致溶血现象。

Reducing afterblowing and using the carburant with low nitrogen content are important measure. The kinetics of nitrogen removal from liquid steel under vacuum with reaction between carbon and oxygen was studied on the multi-function induction furnace. The following conclusions were obtained by experiments: The nitrogen removal was obtained by the nitrogen transfer through the liquid steel diffusion layer at 67Pa and 110Pa pressure, and by the gas-liquid surface chemical reaction at 2000P.

结果表明：真空度对脱氮机理有影响，67Pa～110Pa时脱氮为一级反应，2000Pa时脱氮为二级反应，1340Pa时为混合控制；即使在。1％的条件下，碳氧反应亦可显著提高脱氮速度常数促进深脱氮，在RH内通过加强碳氧反应来提高脱氮率理论上是可行的；当钢液内存在内生或外来固态粒子时，有利于钢液中CO及N〓气泡的形成及排除，这时气泡内p〓≈0，有可能使钢液中氮含量低干与系统真空度平衡的氮含量。
