The peak at 1 550/cm was weak andwide in cancerous tissues but strong and high in normaltissues.The ratio of I1 647/I1 550 was 2.0 in normal tissuesand 2.36 in cancerous tissues (P＜0.05). The ratio of Ⅰ1 550/I 1 080 was 4.5 in normal tissues and 3.4 in canceroustissues (P＜0.01). The peak at 1453/cm was higher than at1 402/cm in normal tissue and lower than at 1 402/cm incancerous tissues.CONCLUSION: The results indicate that F-FIR may be used in clinical diagnosis.展开更多
