应用傅里叶变换红外光谱对 2 0例人乳腺病理样品进行了分析。实验发现 ,乳腺癌组织与乳腺良性病变组织之间有较大的红外光谱差异。与乳腺良性病变组织比较 ,乳腺癌组织的红外光谱中磷酸二酯基团反对称伸缩振动向短波方向位移了 2cm-1,其对称伸缩振动向短波方向位移了 3cm-1;CO伸缩振动吸收A1173/A116 3比值增加 ,A10 2 5/A10 82 比值下降 ;CH3的反对称及对称伸缩振动减弱 ,CH2 的对称及反对称伸缩振动增强。 Twenty cases of human breast pathology were analyzed by Fourier transform infrared spectroscopy. The experiment found that breast cancer tissue and benign breast lesions have a larger infrared spectrum difference between. Compared with benign breast lesions, the anti-symmetric stretching vibration of the phosphodiester group in breast cancer tissues shifted 2cm-1 to the shortwave direction, and the symmetrical stretching vibration shifted to 3cm-1 in the shortwave direction. The CO stretching vibration absorption A1173 / A116 3 ratio, the A10 2 5 / A10 82 ratio decreased; the antisymmetric and symmetric stretching vibration of CH3 weakened, and the symmetry and antisymmetric stretching vibration of CH2 increased.
