本文采用 4 76 .5nm的氩离子激发光激发肝硬化患者及健康人血清样品的自体荧光 ,分析了 4 90 - 6 0 0nm范围内的荧光光谱 ,发现二者光谱的带宽和相对强度比I4 90 /I6 0 0存在明显差异 ,同时使用这两个参量对样品进行分析时 ,与病理结果相比较得到了 76 .5 %的总符合率 ,该结果对肝硬化的光谱诊断有一定的参考价值
In this paper, autofluorescence of serum samples from cirrhotic patients and healthy volunteers was stimulated by 4 76. 5 nm argon ion excitation light. Fluorescence spectra in the range of 4 90-600 nm were analyzed. It was found that the bandwidth and relative intensities of the two spectra were higher than those of I4 90 / I6 0 0, there is a significant difference, while the use of these two parameters of the sample analysis, compared with the pathological results obtained 76.5% of the total coincidence rate, the results of the spectral diagnosis of cirrhosis have a certain reference value
