摘要
本文用傅里叶变换红外显微光谱对一系列胃肠道（食道、胃、结肠）肿瘤组织和相应正常组织的冰冻切片进行了研究，结果显示，所有肿瘤组织的光谱基本一致，而正常组织的光谱按１４００～９５０ｃｍ－１区域的特点可分为三类。对光谱中蛋白质酰胺Ⅰ带曲线拟合的结果表明。
Series of cancer tissues and corresponding normal tissues of gastrointestinal tract (stomach,colon,esophagus) were studied by FTIR technique and the results showed the analogy of the spectra for the cancer tissues,while the spectra of normal tissues can be classified into three kinds.The secondary structures of protein were obtained by using deconvolution and curve fitting techniques with AmideⅠbands and the results showed that the contents of α helix and β sheet are different between the normal and cancer tissues.
