文献多次报导:人体正常组织在4700A附近有一荧光峰,荧光光谱呈钟形,而肿瘤组织除具有4700A 的荧光峰外,在5900A 附近(有的报导为6300A 或6900A 附近),多一个荧光峰,并称此荧光峰为肿瘤的固有荧光。据此,我们开展了实验,其结果和已有的报导有所不符。试验条件、现象及初步结果如下。 The literature has repeatedly reported that human normal tissue has a fluorescence peak near 4700A and its fluorescence spectrum is in a bell shape. In addition to a fluorescence peak of 4700A, the tumor tissue is near 5900A (some reports are near 6300A or 6900A) and there is one more fluorescence peak. , and that this fluorescence peak is the intrinsic fluorescence of the tumor. Based on this, we conducted experiments and the results did not match the existing reports. Test conditions, phenomena, and preliminary results are as follows.
