摘要: 背景与目的:观察维生素E或/和硫辛酸对光气损伤小鼠的抗氧化作用,为临床救治光气中毒提供实验资料。材料与方法: 确定小鼠在光气中毒后体内发生了一定程度的氧化损伤,然后分组给予维生素E或/和硫辛酸,应用全自动血球分析仪进行血液学分析,采用荧光法测定动物肝脏与肺脏MDA。结果:维生素E (6 mg/kg) 或/和硫辛酸 (0.8 mg/kg)对光气引起的全血WBC、PLT降低有促进恢复作用,对肝脏与肺脏MDA的升高有一定的抑制作用,维生素E单用组效果显著,维生素E与硫辛酸复合组效果最差。结论:维生素E对光气导致的脂质过氧化的抗氧化作用优于硫辛酸,维生素E与硫辛酸复合组效果不及单用。

Abstract: BACKGROUND & AIM: To study the antioxidation effcts of Vitamin E or/and lipioc acid on mice injuries caused by phosgene. MATERIAL AND METHODS:50 mice with acute injury induced by phosgene were randomly divided into 5 groups of control, poisoning,Vitamin E,lipioc acid,Vitamin E adding lipioc acid.The WBC and PLT were analyzed with auto-analysis meter,and MDA of liver and lung was determined with fluorometry. RESULTS: The dose of 6 mg/kg Vitamin E or/and 0.8 mg/kg lipioc acid could increase the amounts of WBC and PLT in peripheral blood(P<0.05)and inhibit MDA level of liver and lung. The group Vitamin E showed best inhibition on MDA (P<0.05).The group of Vitamin E plus lipioc acid did not show significant cooperative effect;on the contrary they came forth antagonistic effect. CONCLUSION: The antioxidation effect of Vitamin E is better than lipioc acid on mice injuries caused by phosgene. Among three groups,the group of Vitamin E plus lipioc acid has certain antagonism in inhibiting the level of MDA.
