Parameters of lipid peroxidation and the levels of calcium ions in blood plasma and exhaled air condensate (EAC) were studied in 47 patients with lung cancer. The changes in EAC turned out to be more specific than those of blood plasma. The level of lipoperoxidation in condensate in cancer patients was lower than in healthy subjects. However, calcium cations concentrations in both blood and EAC were relatively higher, the latter difference being significant. The investigation pointed to a greater diagnostic value of EAC measurements, as compared with blood plasma, in lung cancer patients.
对47例肺癌患者的脂质过氧化参数以及血浆和呼出气冷凝液（EAC）中的钙离子水平进行了研究。结果发现，EAC中的变化比血浆中的变化更具特异性。癌症患者冷凝液中的脂质过氧化水平低于健康受试者。然而，血液和EAC中的钙阳离子浓度相对较高，后者的差异具有显著性。该研究表明，与血浆相比，测量EAC对肺癌患者具有更大的诊断价值。
