机体内脂质过氧化作用(LPO)已引起多学科的关注。对体内LPO程度的确定,国内目前普遍用硫代巴比土酸法测定血中丙二醛,以评价机体发生LPO的程度。但由于丙二醛十分活泼,易与机体内其它组分反应,从而影响了它作为反映LPO程度的准确性。RielyCA等和Dillard CJ等相继报导了用气相色谱法(G.C)测定动物机体内LPO过程中释放到呼出气中的乙烷和戊烷。作者为使LPO的呼气分析用于人群监测,而建 Lipid peroxidation (LPO) in the body has attracted multi-disciplinary attention. To determine the extent of LPO in vivo, the current domestic widespread use of thiobarbituric acid in the blood of malondialdehyde, to assess the extent of the body LPO. However, due to the fact that malondialdehyde is very reactive, it easily reacts with other components in the body, thus affecting its accuracy as a proxy for the degree of LPO. Riely CA et al., And Dillard CJ et al. Reported on the determination of ethane and pentane released into the exhaled breath during LPO in animals using gas chromatography (G.C.). The author built the LPO’s breath analysis for crowd monitoring
