癌症患者血清的激光拉曼光谱

按正常人和不同种类癌症患者进行分类，用激光拉曼光谱分别对正常人，鼻咽癌患者、肝癌患者和慢性白血病患者四类受试者的血清在０－２０００ｃｍ＾－１范围内进行测试。结果表明，同类患者中不同受试者血清的激光拉曼光谱特征峰值大小虽然不同，但光谱图特征基本一致；不同种类癌症患者血清的激光拉曼光谱图存在较大差异；在各类癌症患者血清的激光拉曼光谱图特征峰附近，正常人血清均没有拉曼光谱特征峰。

Raman Spectra of the Serums from Cancerous Persons

The serums of different categories, those who are normal people and those who are patient suffering from nasopharyngeal cancer, liver cancer and chronic leukaemia, were determined by laser Raman spectra at the range of 0-2,000 cm-1. The results demonstrated that the serums of those who are suffering from the same disease show different characteristic peak height, but their Raman spectrogram characteristics are almost the same. There exists great difference in the laser Raman spectrogram for the serums of the different kinds of cancerous patients. Near the characteristic peaks of laser Raman spectrograms of serums from the cancerous patients, the normal person's serum has no Raman spectrogram characteristic peak.
