肺癌病人头发自由基电子自旋共振波谱(ESR)饱和特性研究——139例报道

Study on the Characteristics of Electron Spin Resonance Saturation Power in the Hair of 139 Patients with pulmonary Carcinoma

本文报道用电子自旋共振波谱(ESR)技术测定129例原发性支气管肺癌患者头发自由基的饱合功率特性并与1000例正常人结果比较,发现肺癌患者ESR-SP值大多较低,139例次中除1例为2.5mw以外,其余均在2.5mw以下;无3mw以上病例,81.3％低于2mw,而正常人96.1％在2mw以上。肺癌组的ESR-SP值中位数及95％上下限与正常人差异有极显著性。

The saturation power (SP) of the free radical of hair in the 139 patients with primary pulmonary carcinoma was determined by using the technlque of Electron Spin Resonance(ESP),and compared with that in the 1000 normals hair.It was found that the values of ESR-SP were lower in most of the patients with pulmonary carcinoma.The values in all patients, except one was 2.5mw,were under 2.5mw, none of the cases was over than 3mw, 81.3% of them were under 2mw; but 96.1% of the values in normals were above 2mw.The differences of the median values of ESR-SP and the values of 95% upper and lower limits between the patients and the normals were significant.
