摘要
目的探讨在300 nm波长光激发下,利用340 nm自体荧光成像技术诊断乳腺癌和结肠癌的方法。方法在相同实验条件下对21例乳腺癌和结肠癌样本进行自体荧光成像,比较和测量肿瘤组织、正常组织、脂肪组织、血管组织的荧光强度。结果实验结果表明,样本中肿瘤组织的荧光强度高于其他组织,脂肪组织和血管组织的荧光强度要低于正常组织。结论乳腺和结肠的自体荧光图像中各组织荧光强度有明显的差异,可以作为诊断的辅助手段。
Objective To discuss the method of diagnosing human breast cancer and colon cancer using 340 nm native lfuorescence imaging triggered by 300 nm light. Methods Autolfuorescence imaging was performed on 21 samples of human breast and colon tissues under the same experimental conditions. The intensity of neoplastic, normal, fat, and blood vessel tissues was measured and compared. Results The results indicated that the intensity of the autolfuorescence of tumor tissue was typically higher, and the intensity of fat and blood vessel tissue was lower than that of normal tissue. Conclusion Different intensity of native lfuorescence of tissues was tested in breasts and colons, which can be used as auxiliary diagnosis.
