| 摘 要： | 用快速低温冷冻-ESR实验方法研究兔脂肪栓塞模型脑组织自由基的变化,实验发现脂肪栓塞实验组自由基相对浓度是正常对照组的2-3倍。ESR检测到脂类过氧化自由基和以碳为中心的烷基类自由基的事实表明脂肪栓塞病变存在活性氧自由基作用过程。文中对快速冷冻法可行性进行评估。

| Abstract: | A Rapidly-frozen technique and ESR method were used to directly measure free radicals generation in rabbit brain tissues due to venous fat-embolism.It had been found that ESR signal intensities of free radicals for the experimental fat-embolism group are 2-3 times higher than those for norinal contrast groups.The appearance of the lipid peroxyl radicals and the carbon-centered alkyl radicals provides an evidence that the fat-embolism pathologenesis may involve an active-oxygen radical action.In this paper the advantage of the rapidly-frozen method and its feasibility are elucidated. |
